Below is general information about the safety of the known ingredients contained in the product Menopause Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. Black cohosh has been safely used in some studies lasting up to a year (15036,15158,17091,19553,35908); however, most studies have lasted only up to 6 months (141,4614,4620,7054,9437,9494,13143,13184,14330,14423)(14424,15037,15889,15893,35824,35852,35853,35858,35865,35897)(35902,35904,35946,35964,95525,103269). There is concern that black cohosh might cause liver damage in some patients. Several case reports link black cohosh to liver failure or autoimmune hepatitis (4383,10692,11906,12006,13144,14469,15160,16721,16722,16723)(16724,16725,16726,16727,35857,107906). However, the evidence that black cohosh causes liver damage is not conclusive (17085). Until more is known, monitor liver function in patients who take black cohosh.
PREGNANCY: POSSIBLY UNSAFE
when used orally in pregnant patients who are not at term.
Black cohosh might have hormonal effects and menstrual and uterine stimulant effects (15035). Theoretically, this might increase the risk of miscarriage; avoid using during pregnancy. There is insufficient reliable information available about the safety of black cohosh when used to induce labor.
LACTATION: POSSIBLY UNSAFE
when used orally.
Black cohosh might have hormonal effects. Theoretically, maternal intake of black cohosh might adversely affect a nursing child (15035). Until more is known, nursing patients should avoid taking black cohosh.
POSSIBLY SAFE ...when used orally and appropriately. Gamma-oryzanol 300 mg daily has been used most commonly in clinical research without reports of adverse events (751,752,753,754,755,51111). ...when used topically and appropriately (51112).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Grapefruit has Generally Recognized as Safe status (GRAS) in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes. A grapefruit seed extract has been safely used in clinical research (5866). In addition, capsules containing grapefruit pectin 15 grams daily have been used in clinical research for up to 16 weeks (2216).
POSSIBLY UNSAFE ...when used orally in excessive amounts. Preliminary population research shows that consuming a quarter or more of a whole grapefruit daily is associated with a 25% to 30% increased risk of postmenopausal breast cancer (14858). Grapefruit juice is thought to reduce estrogen metabolism resulting in increased endogenous estrogen levels. More evidence is needed to validate this finding.
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of using medicinal amounts of grapefruit during pregnancy and lactation; avoid using.
LIKELY SAFE ...when used orally in amounts found in foods.
POSSIBLY SAFE ...when supplements are used orally and appropriately, short-term. Doses of up to 3 grams daily have been used with apparent safety for up to 3 months (37494,54850,94544,105275,105276).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts found in foods.
PREGNANCY AND LACTATION: POSSIBLY SAFE
when used orally in doses of up to 100 mg daily for 30 days in combination with diosmin.
Some evidence suggests that taking this combination may be associated with placental insufficiency when used during the third trimester of pregnancy; however, the combination does not seem to induce fetal abnormalities, retard fetal growth, increase the risk of intrauterine death, or affect birth weight. Also, when breastfeeding, this combination does not seem to affect infant growth or feeding (54970).
LIKELY SAFE ...when used in amounts commonly found in foods. Lemon has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when inhaled in amounts used for aromatherapy, short-term. Lemon essential oil has been used with apparent safety as aromatherapy for up to 2 weeks in clinical research (93475,98128,98129). There is insufficient reliable information available about the safety of lemon when used topically, or when used orally or intranasally in medicinal amounts.
PREGNANCY AND LACTATION:
Insufficient reliable information available.
Avoid using in amounts greater than those typically found in foods.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Lime has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).
POSSIBLY UNSAFE ...when used topically. Lime oil and lime juice contain photosensitizing constituents (12,11019,40894,59925,59928,100125,100126,100129). ...when used intravaginally. Lime juice has caused mild to moderate adverse effects in women using lime juice-soaked tampons or as a douche, especially in concentrations of 20% or more (100127,100128). There is insufficient reliable information available about the safety of lime when used orally in medicinal amounts.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than those typically found in foods.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Sage is approved for use as a food in the United States (4912).
POSSIBLY SAFE ...when used orally in medicinal doses, short-term. Common sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) have been used with apparent safety when taken orally in doses of 280 mg daily for up to 8 weeks (10334,10810,17177,105338). ...when used topically. Common sage (Salvia officinalis) has been used with apparent safety as a single agent or in combination products for up to one week (10437,72619,107023). ...when the essential oil is inhaled as aromatherapy, short-term (72658).
POSSIBLY UNSAFE ...when used orally in high doses or long-term (12,1304). Some species of sage, including common sage (Salvia officinalis), contain a thujone constituent that can be toxic if consumed in large enough quantities (12,1304).
PREGNANCY: LIKELY UNSAFE
when used orally.
The constituent thujone can have menstrual stimulant and abortifacient effects (19).
LACTATION: POSSIBLY UNSAFE
when used orally; sage is thought to reduce the supply of mother's milk (19).
LIKELY SAFE ...when sweet orange juice or fruit is used orally in amounts commonly found in foods (1310,3340,15171,92309,114401).
POSSIBLY SAFE ...when the essential oil of sweet orange is inhaled as aromatherapy, short-term (35735,58060,90505,105455). There is insufficient reliable information available about the safety of sweet orange peel when used orally.
CHILDREN: LIKELY SAFE
when sweet orange juice or fruit is used orally in amounts commonly found in foods.
CHILDREN: POSSIBLY UNSAFE
when the sweet orange peel is used orally in excessive amounts.
There have been reports of intestinal colic, convulsions, and death in children given large amounts of sweet orange peel (11).
PREGNANCY AND LACTATION: LIKELY SAFE
when sweet orange juice or fruit is used orally in amounts commonly found in foods (1310,3340).
LIKELY SAFE ...when used orally in amounts commonly found in foods. Tangerine has Generally Recognized as Safe (GRAS) status in the US (4912). There is insufficient reliable information available about the safety of tangerine when used orally or topically as a medicine.

Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Menopause Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
 Details
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued (16725). It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.
|
Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Details
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells (13101).
|
Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Details
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme (13536). However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers (16848). Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.
|
Theoretically, black cohosh may alter the effects of estrogen therapy.
Details
|
Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
Details
|
Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
Details
In vitro research shows that black cohosh modestly inhibits OATP2B1 (35450). OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
|
Grapefruit juice can decrease blood levels of acebutolol, potentially decreasing the clinical effects of acebutolol.
Details
Clinical research shows that grapefruit juice can modestly decrease acebutolol levels by 7% and reduce peak plasma concentration by 19% by inhibiting organic anion transporting polypeptide (OATP) (17603,18101). The acebutolol half-life is also extended by 1.1 hours when grapefruit juice is consumed concomitantly (18101). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of aliskiren, potentially decreasing the clinical effects of aliskiren.
Details
Clinical research shows that grapefruit juice can decrease aliskiren levels by approximately 60% by inhibiting organic anion transporting polypeptide (OATP) (91428). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of amiodarone, potentially increasing the effects and adverse effects of amiodarone.
Details
|
Grapefruit juice might decrease blood levels of amprenavir, although this is not likely to be clinically significant.
Details
Some clinical research shows that grapefruit juice can slightly decrease amprenavir levels (17673); however, this is probably not clinically significant.
|
Grapefruit juice can increase blood levels of oral artemether, potentially increasing the effects and adverse effects of artemether.
Details
|
Grapefruit juice might increase blood levels of some oral benzodiazepines, potentially increasing the effects and adverse effects of these drugs.
Details
Clinical research shows that grapefruit juice can increase plasma triazolam concentrations. Repeated consumption of grapefruit juice greatly increases triazolam concentrations and prolongs the half-life, probably due to inhibition of cytochrome P450 3A4 (CYP3A4) (7776,22118,22131,22133). Some studies show that grapefruit juice, particularly when taken in large quantities, reduces the clearance and increases the maximum blood levels, area under the plasma concentration curve (AUC), and duration of effect of midazolam. However, there is no effect on intravenous midazolam (4300,10159,11275,17601,22117,22119,16711,91427,95978). Grapefruit juice has also been shown to increase the maximum blood levels and duration of effect of diazepam, but the clinical significance of this is not known (3228). This interaction does not appear to occur with alprazolam (17674).
|
Grapefruit juice can increase blood levels of blonanserin, potentially increasing the effects and adverse effects of blonanserin.
Details
Blonanserin is metabolized primarily by cytochrome P450 3A4 (CYP3A4). A small clinical study shows that taking grapefruit juice along with oral blonanserin increases exposure to blonanserin almost 6-fold due to inhibition of intestinal CYP3A4 by grapefruit juice and prolongs the elimination half-life of blonanserin by 2.2-fold due to inhibition of hepatic CYP3A4 by grapefruit juice (96943).
|
Grapefruit juice can increase blood levels of budesonide, potentially increasing the effects and adverse effects of budesonide.
Details
Budesonide is metabolized by cytochrome P450 3A4 (CYP3A4). A small clinical study shows that taking grapefruit juice along with oral budesonide increases the plasma concentration of budesonide. This effect is attributed to grapefruit-induced inhibition of CYP3A4 in both the colon and small intestine (91425).
|
Grapefruit juice can increase blood levels of buspirone, potentially increasing the effects and adverse effects of buspirone.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of buspirone (3771).
|
Grapefruit juice can decrease the clearance of caffeine, potentially increasing the effects and adverse effects of caffeine.
Details
Clinical research shows that grapefruit juice decreases caffeine clearance (4300).
|
Grapefruit juice can increase blood levels of oral calcium channel blockers, potentially increasing the effects and adverse effects of these drugs.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of amlodipine (523), nifedipine (528,22114), nisoldipine (529), verapamil (7779,8285), felodipine, nimodipine, nicardipine, diltiazem, pranidipine, nitrendipine, and manidipine (524,528,1388,4300,7780,11276,22136,53338,22138,22139) (22140,22141,22142,22143,22147,22148,22149,53367,22158),
This interaction is likely the result of the inhibition of intestinal metabolism of these drugs by CYP3A4 (7779,7780), although some research suggests grapefruit may alter plasma drug levels by reducing the rate of gastric emptying (22167). Consuming grapefruit juice 1 liter daily increases steady state concentrations of verapamil by as much as 50% (8285). However, some references dispute the clinical relevance of the interactions with amlodipine, diltiazem, and verapamil (3230,4300,22159). Other research in healthy individuals suggests plasma levels of felodipine and nifedipine are not affected when given intravenously (22144,22146). There is considerable interindividual variability in the effect of grapefruit juice on drug metabolism, which might account for inconsistent study results (7777,7779,8285). In healthy older adults, the hemodynamic response to felodipine plus grapefruit juice might be influenced by altered autonomic regulation. In older healthy adults, a single dose of grapefruit juice and felodipine enhanced the blood pressure-lowering effects of felodipine. However, after a week of grapefruit juice and felodipine (steady state), the hypotensive activity was reduced, possibly due to compensatory tachycardia (1392). Research indicates it is necessary to withhold grapefruit juice for as long as 3 days to avoid interactions with felodipine and nisoldipine (5068,5069,6453,22145).
|
Grapefruit juice can increase blood levels of carbamazepine, potentially increasing the effects and adverse effects of carbamazepine.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of carbamazepine (524).
|
Grapefruit juice can increase blood levels of carvedilol, potentially increasing the effects and adverse effects of carvedilol.
Details
Clinical research shows that grapefruit juice increases the bioavailability of a single dose of carvedilol by 16% (5071).
|
Grapefruit juice can decrease blood levels of celiprolol, potentially decreasing the clinical effects of celiprolol.
Details
In human research, taking grapefruit juice within two hours of celiprolol appears to decrease absorption and blood levels of celiprolol by approximately 85% (91421). This interaction is due to grapefruit-induced inhibition of organic anion transporting polypeptide (OATP) (17603,17604,22161). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of cisapride, potentially increasing the effects and adverse effects of cisapride.
Details
|
Theoretically, grapefruit juice might increase blood levels of clomipramine, potentially increasing the effects and adverse effects of clomipramine.
Details
Case reports have shown that clomipramine trough levels increase significantly after the addition of grapefruit juice to the therapeutic regimen (5064).
|
Grapefruit juice can decrease blood levels of the active metabolite of clopidogrel, thereby decreasing the antiplatelet effect of clopidogrel.
Details
Clopidogrel is an antiplatelet prodrug that is metabolized primarily by cytochrome P450 2C19 (CYP2C19) to form the active metabolite. A small clinical study shows that taking grapefruit juice with clopidogrel decreases plasma levels of the active metabolite by more than 80% and impairs the antiplatelet effect of clopidogrel. This effect is possibly due to grapefruit-induced inhibition of CYP2C19 (91419).
|
Theoretically, grapefruit juice might increase blood levels of colchicine, potentially increasing the effects and adverse effects of colchicine.
Details
Colchicine is an alkaloid that undergoes P-glycoprotein (P-gp) mediated drug efflux in the intestines, followed by metabolism by cytochrome P450 3A4 (CYP3A4). There is concern that grapefruit juice will increase the effects and adverse effects of colchicine due to grapefruit-induced inhibition of P-gp and/or CYP3A4. In vitro evidence shows that grapefruit juice increases absorption of colchicine by inhibiting P-gp (94158). A case of acute colchicine toxicity has been reported for an 8-year-old female who drank grapefruit juice while taking high-dose colchicine, long-term (94157). However, one small clinical study in healthy adults shows that drinking grapefruit juice 240 mL twice daily for 4 days does not affect the bioavailability or adverse effects of a single dose of colchicine 0.6 mg taken on the fourth day (35762).
|
Grapefruit juice can increase blood levels of oral cyclosporine, potentially increasing the effects and adverse effects of cyclosporine.
Details
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP1A2.
Details
In vitro research suggests that grapefruit juice might inhibit CYP1A2 enzymes (12479). So far, this interaction has not been reported in humans.
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP2C19.
Details
In vitro research suggests that grapefruit juice might inhibit CYP2C19 enzymes (12479). Also, a small clinical study shows that taking grapefruit juice with clopidogrel, an antiplatelet prodrug that is metabolized primarily by CYP2C19, decreases plasma levels of the active metabolite and impairs the antiplatelet effect of clopidogrel. This effect is likely due to grapefruit-induced inhibition of CYP2C19 (91419).
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP2C9.
Details
In vitro research suggests that grapefruit juice might inhibit CYP2C9 enzymes (12479). So far, this interaction has not been reported in humans.
|
Grapefruit juice can increase levels of drugs metabolized by CYP3A4.
Details
Clinical research shows that grapefruit juice can inhibit CYP3A4 metabolism of drugs, causing increased drug levels and potentially increasing the risk of adverse effects (3227,3774,8283,8285,8286,22129,91427,104190). When taken orally, effects of grapefruit juice on CYP3A4 levels appear to last at least 48 hours (91427). Grapefruit's ability to inhibit CYP3A4 has even been harnessed to intentionally increase levels of venetoclax, which is metabolized by CYP3A4, in an elderly patient with acute myeloid leukemia who could not afford full dose venetoclax. The lower dose of venetoclax in combination with grapefruit juice resulted in serum levels of venetoclax in the therapeutic reference range of full dose venetoclax and positive treatment outcomes for the patient (112287).
Professional consensus recommends the consideration of patient age, existing medical conditions, additional medications, and the potential for additive adverse effects when evaluating the risks of concomitant use of grapefruit juice with any medication metabolized by CYP3A4. While all patients are at risk for interactions with grapefruit juice consumption, patients older than 70 years of age and those taking multiple medications are at the greatest risk for a serious or fatal interaction with grapefruit juice (95970,95972). |
Grapefruit juice can increase blood levels of dapoxetine, potentially increasing the effects and adverse effects of dapoxetine.
Details
Pharmacokinetic research shows that drinking grapefruit juice 250 mL prior to taking dapoxetine 60 mg can increase the maximum plasma concentration of dapoxetine by 80% and prolong the elimination half-life by 43%. This effect is attributed to the inhibition of both intestinal and hepatic cytochrome P450 3A4 (CYP3A4) by grapefruit (95975).
|
Grapefruit juice can increase blood levels of dextromethorphan, potentially increasing the effects and adverse effects of dextromethorphan.
Details
Clinical research shows that grapefruit juice can inhibit cytochrome P450 3A4 (CYP3A4) metabolism, causing increased dextromethorphan levels (11362).
|
Theoretically, grapefruit juice may increase the levels and clinical effects of empagliflozin.
Details
Animal research suggests grapefruit juice increases the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of empagliflozin, possibly due to inhibition of metabolism by uridine diphosphoglucuronosyl transferase (UGT) (115467). This effect has not been reported in humans.
|
Grapefruit juice can increase blood levels of erythromycin, potentially increasing the effects and adverse effects of erythromycin.
Details
Clinical research shows that concomitant use of erythromycin with grapefruit can inhibit cytochrome P450 3A4 (CYP3A4) metabolism of erythromycin, increasing plasma concentrations of erythromycin by 35% (8286).
|
Grapefruit juice can increase blood levels of estrogens, potentially increasing the effects and adverse effects of estrogens.
Details
Clinical research shows that grapefruit increases the levels of endogenous and exogenous estrogens by inhibiting cytochrome P450 3A4 (CYP3A4) enzymes (525,526,14858). Grapefruit juice increases exogenously administered 17-beta-estradiol by about 20% in females without ovaries and ethinyl-estradiol in healthy females (525,526,22160).
|
Grapefruit juice can decrease blood levels of etoposide, potentially decreasing the clinical effects of etoposide.
Details
Clinical research shows that grapefruit juice decreases the absorption and plasma concentrations of etoposide. There is some evidence that grapefruit juice co-administered with oral etoposide can reduce levels of etoposide by about 26% (8744). Grapefruit juice seems to inhibit organic anion transporting polypeptide (OATP), which is a drug transporter in the gut, liver, and kidney (7046,17603,17604). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of fexofenadine, thereby decreasing the clinical effects of fexofenadine.
Details
Clinical research shows that grapefruit juice can significantly decrease oral absorption and blood levels of fexofenadine. In one study, consuming a drink containing grapefruit juice 25% decreased bioavailability of fexofenadine by about 24%. Consuming a full-strength grapefruit juice drink reduced bioavailability by 67% (7046). In another study, consuming grapefruit juice 300 mL decreased fexofenadine levels by 42%. Consuming 1200 mL of grapefruit juice reduced levels by 64% (17602). Similarly, drinking grapefruit juice 240 mL decreased the oral bioavailability of fexofenadine by 25% in another pharmacokinetic study (112288). Fexofenadine manufacturer data indicates that concomitant administration of grapefruit juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that grapefruit also reduces the clinical response to fexofenadine (17603).
Grapefruit juice seems to inhibit organic anion transporting polypeptide (OATP), which is a drug transporter in the gut, liver, and kidney (7046,17603,17604,22161). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604). |
Grapefruit juice can increase blood levels of fluvoxamine, potentially increasing the effects and adverse effects of fluvoxamine.
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases fluvoxamine levels and peak concentration (17675).
|
Grapefruit juice can increase blood levels of halofantrine, potentially increasing the effects and adverse effects of halofantrine.
Details
Clinical research shows that grapefruit juice inhibits cytochrome P450 3A4 (CYP3A4) metabolism, which increases halofantrine levels and peak concentration, as well as a marker of ventricular tachyarrhythmia potential (22129).
|
Grapefruit juice can increase blood levels of statins that are metabolized by cytochrome P450 3A4 (CYP3A4), potentially increasing the effects and adverse effects of these statins. Additionally, grapefruit juice might interfere with the bioavailability of statins that are substrates of organic anion transporting polypeptides (OATP).
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases absorption and plasma concentrations of statins that are metabolized by CYP3A4. These include lovastatin (527,11274), simvastatin (3774,7782,22127), and atorvastatin (3227,12179,22126). Keep in mind that there is considerable variability in the effect of grapefruit juice on drug metabolism, so individual patient response is difficult to predict (7777,7781).
Some statins, including pravastatin, fluvastatin, pitavastatin, and rosuvastatin, are not metabolized by CYP3A4. However, grapefruit juice might still affect the bioavailability of these statins. These statins are substrates of OATP. Grapefruit juice can inhibit OATP. Therefore, grapefruit juice may reduce the bioavailability or increase drug levels of these statins depending on the type of OATP. However, grapefruit juice affects OATP for only a short time. Therefore, separating drug administration by at least 4 hours is likely to avoid this interaction (3227,12179,17601,22126,91420). |
Grapefruit juice can interfere with itraconazole absorption, although the clinical significance of this interaction is unclear.
Details
|
Grapefruit juice can decrease blood levels of levothyroxine, potentially decreasing the effectiveness of levothyroxine.
Details
Clinical research shows that grapefruit juice modestly decreases levothyroxine levels by 11% by inhibiting organic anion transporting polypeptide (OATP) (17604,22163). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of the active metabolite of losartan, potentially decreasing the clinical effects of losartan.
Details
Losartan is an inactive prodrug which must be metabolized to its active form, E-3174, to be effective. In one human study, grapefruit juice reduced losartan metabolism, increased losartan AUC, and reduced the AUC of the major active losartan metabolite, E-3174 (1391).
|
Grapefruit juice can increase blood levels of methadone, potentially increasing the effects and adverse effects of methadone.
Details
Clinical research shows that grapefruit juice inhibits the metabolism of methadone, increasing methadone levels and peak concentrations (17676). In one case, a 51-year-old male taking methadone 90 mg daily and no other medications was found unresponsive. The patient reported drinking grapefruit juice 500 mL daily for 3 days prior to the event. Methadone is a substrate of cytochrome P450 3A4 (CYP3A4), and grapefruit juice-induced inhibition of CYP3A4 is the likely cause of this interaction (102056).

Grapefruit juice can increase blood levels of methylprednisolone, potentially increasing the effects and adverse effects of methylprednisolone.
Details
Clinical research shows that grapefruit juice can increase the plasma concentration of orally administered methylprednisolone. Grapefruit juice 200 mL three times daily given with methylprednisolone 16 mg increased methylprednisolone half-life by 35%, peak plasma concentration by 27%, and total area under the curve by 75% (3123).
|
Grapefruit juice might decrease blood levels of nadolol, potentially decreasing the clinical effects of nadolol.
Details
Nadolol is a substrate of organic anion transporting polypeptide 1A2 (OATP1A2) (17603,17604,22161). Some research shows that grapefruit juice and its constituent naringin can inhibit organic anion transporting polypeptides (OATP), which can reduce the bioavailability of OATP substrates (17603,17604,22161,91427). However, preliminary clinical research shows that grapefruit juice containing a low amount of naringin does not significantly affect levels of nadolol (91422). It is not known if grapefruit juice containing higher amounts of naringin reduces the bioavailability of nadolol.
|
Grapefruit juice can increase blood levels of nilotinib, potentially increasing the effects and adverse effects of nilotinib.
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases absorption of nilotinib. Grapefruit juice increases nilotinib levels by 29% and peak concentration by 60% (17677).
|
Grapefruit juice can decrease levels of drugs that are substrates of OATP.
Details
In vitro and clinical research show that consuming grapefruit juice inhibits OATP, which reduces the bioavailability of oral drugs that are substrates of OATP. Various clinical studies have shown reduced absorption of OATP substrates when taken with grapefruit, including fexofenadine, acebutolol, aliskiren, celiprolol, levothyroxine, nadolol, and pitavastatin (17603,17604,18101,22126,22134,22161,22163,91420,91427,91428,112288). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of oxycodone, potentially increasing the effects and adverse effects of oxycodone.
Details
Oxycodone is metabolized by both cytochrome P450 3A4 (CYP3A4) and cytochrome P450 2D6 (CYP2D6). A small clinical study shows that grapefruit juice can increase plasma levels of oral oxycodone about 1.7-fold by inhibiting CYP3A4. While the analgesic effects of oxycodone do not seem to be affected, taking grapefruit juice along with oxycodone may theoretically increase the adverse effects of oxycodone (91423).
|
Grapefruit juice does not seem to affect renal P-glycoprotein (P-gp). Theoretically, it might inhibit intestinal P-gp, but evidence is conflicting.
Details
While most in vitro research shows that grapefruit products inhibit P-gp, (1390,11270,11278,11362,95976), research in humans is less clear. Two small clinical studies in healthy adults using digoxin as a probe substrate show that grapefruit juice does not inhibit P-gp in the kidneys (11277,11282). It is unclear whether this applies to intestinal P-gp, for which digoxin is not considered to be a sensitive probe (105568). Grapefruit juice has been shown to reduce levels of fexofenadine (7046,17602,112288), and increase levels of quinidine (5067,22121). However, as both of these drugs are also substrates of other enzymes and transporters, it is unclear what role, if any, intestinal P-gp has in these findings.
|
Grapefruit juice can increase blood levels of pitavastatin, potentially increasing the effects and adverse effects of pitavastatin.
Details
Pharmacokinetic research shows that taking grapefruit juice with pitavastatin 2-4 mg can increase blood levels of pitavastatin by 13% to 14%. Unlike simvastatin and atorvastatin, pitavastatin is not significantly metabolized by cytochrome P450 3A4 (CYP3A4) enzymes. Grapefruit juice appears to increase levels of pitavastatin by inhibiting its uptake by organic anion transporting polypeptide 1B1 (OATP1B1) into hepatocytes for metabolism and clearance from the body (22126,91420). Grapefruit juice seems to increase levels of pitavastatin to a greater degree in patients homozygous for a specific polymorphism (388A>G) in the OATP1B1 gene compared to those heterozygous for this polymorphism (91420).
|
Grapefruit juice can decrease blood levels of the active metabolite of prasugrel, thereby decreasing the antiplatelet effect of prasugrel.
Details
Prasugrel is a prodrug that is metabolized by cytochrome P450 3A4 (CYP3A4) into its active metabolite. A small pharmacokinetic study in healthy volunteers shows that drinking grapefruit juice 200 mL three times daily for 4 days and taking a single dose of prasugrel 10 mg with an additional 200 mL of grapefruit juice on day 3, results in a 49% lower peak plasma level and a 26% lower overall plasma exposure to the active metabolite when compared with drinking water. However, despite the reduced exposure, platelet aggregation seems to be reduced by an average of only 5% (105567). The clinical significance of this interaction is unclear.
|
Grapefruit juice can increase blood levels of praziquantel, potentially increasing the effects and adverse effects of praziquantel.
Details
Clinical research shows that grapefruit juice can inhibit cytochrome P450 3A4 (CYP3A4) metabolism of praziquantel. Plasma concentrations of praziquantel can increase by as much as 160% when administered with 250 mL of commercially available grapefruit juice (8282).
|
Grapefruit juice may increase blood levels of primaquine, potentially increasing the effects and adverse effects of primaquine.
Details
Clinical research shows that grapefruit juice increases the bioavailability of primaquine by approximately 20% (22130). The clinical significance of this interaction is not clear.
|
Grapefruit or grapefruit juice, especially if consumed in large amounts, can cause additive QT interval prolongation when taken with QT interval-prolonging drugs, potentially increasing the risk of ventricular arrhythmias.
Details
Clinical research in healthy volunteers shows that drinking 6 liters of grapefruit juice over 6 hours prolonged the QTc by a peak amount of 14 milliseconds (ms). This prolongation was similar to the QT prolongation caused by the drug moxifloxacin. In individuals with long QT syndrome, a smaller dose of grapefruit juice, 1.5 liters, resulted in a greater peak QTc prolongation of about 30 ms (100249). The effect of smaller quantities of grapefruit juice on the QT interval is unclear.
|
Grapefruit juice may increase blood levels of quetiapine, increasing the effects and adverse effects of quetiapine.
Details
Quetiapine is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4 (3227,3774,8283,8285,8286,22129,91427,104190). In one case report, a healthy 28-year-old female with bipolar disorder stabilized on quetiapine 800 mg daily presented with quetiapine toxicity considered to be related to consuming a gallon of grapefruit juice over the past 24 hours (108848).
|
Grapefruit juice can alter blood levels of quinidine, potentially increasing or decreasing the clinical effects of quinidine.
Details
|
Theoretically, grapefruit juice may increase the concentration and clinical effects of rivaroxaban.
Details
Rivaroxaban is metabolized partially by cytochrome P450 3A4 (CYP3A4). Grapefruit juice can inhibit CYP3A4. Animal research shows that grapefruit juice increases the peak plasma concentration (Cmax) of rivaroxaban by about four-fold, without increasing the area under the drug concentration-time curve (AUC) (115468).
|

|
Grapefruit juice can increase blood levels of sildenafil, potentially increasing the effects and adverse effects of sildenafil.
Details
Clinical research shows that grapefruit juice inhibits cytochrome P450 3A4 (CYP3A4) metabolism of sildenafil, increasing its absorption and plasma concentrations. Oral bioavailability of sildenafil can increase by 23% when administered with 500 mL of commercially available grapefruit juice (8283).
|
Grapefruit juice may slightly increase blood levels of sunitinib, potentially increasing the effects and adverse effects of sunitinib.
Details
Sunitinib is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit and grapefruit juice can inhibit CYP3A4 and increase levels of some drugs metabolized by this enzyme. One small clinical study shows that drinking 200 mL of grapefruit juice three times daily can increase the bioavailability of sunitinib by 11% (91429). While this effect is unlikely to be clinically significant, patients should use caution when using grapefruit along with sunitinib. Dose adjustments may be necessary.
|
Grapefruit juice can increase blood levels of tacrolimus, potentially increasing the effects and adverse effects of tacrolimus.
Details
Clinical research shows that drinking grapefruit juice 200 mL daily while taking tacrolimus 3 mg daily increases the trough blood concentration of tacrolimus by approximately 3-fold in patients with connective tissue diseases (95974). A single case has also reported a 10-fold increase in tacrolimus trough levels after the ingestion of grapefruit juice over 3 days (22122). This effect is attributed to the inhibition of cytochrome P450 3A4 (CYP3A4) by grapefruit (95974).
|
Theoretically, grapefruit juice might increase blood levels of tadalafil, potentially increasing the effects and adverse effects of tadalafil.
Details
Animal research shows that grapefruit juice increases tadalafil serum concentrations and overall exposure, likely through inhibition of cytochrome P450 3A4 enzymes (104189).
|
Grapefruit juice might decrease blood levels of talinolol, potentially decreasing the clinical effects of talinolol.
Details
Clinical research suggests that grapefruit juice reduces talinolol bioavailability, likely by inhibiting intestinal uptake (22135). The clinical significance of this effect is unclear.
|
Grapefruit juice can increase blood levels of terfenadine, potentially increasing the effects and adverse effects of terfenadine.
Details
|
Grapefruit juice can decrease blood levels of theophylline, potentially decreasing the effectiveness of theophylline.
Details
Clinical research shows that grapefruit juice seems to modestly decrease theophylline levels when given concurrently with sustained-release theophylline (11013). The mechanism of this interaction is unknown.
|
Grapefruit juice can increase blood levels of ticagrelor, thereby increasing the effects and adverse effects of ticagrelor.
Details
Ticagrelor is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4. A small clinical study shows that taking grapefruit juice with ticagrelor increases blood levels of ticagrelor more than two-fold and increases the antiplatelet activity of ticagrelor (91418). Additionally, animal research shows that grapefruit juice increases peak plasma concentration (Cmax) and the area under the drug concentration-time curve (AUC) of ticagrelor (115468).
|
Grapefruit juice can increase blood levels of tolvaptan, potentially increasing the effects and adverse effects of tolvaptan.
Details
Tolvaptan is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4. A small clinical study shows that grapefruit juice can increase the bioavailability and blood levels of tolvaptan by approximately 1.6-fold for up to 16 hours (91426).
|
Theoretically, drinking large amounts of grapefruit juice might increase the effects and adverse effects of warfarin.
Details
In one case report, a patient experienced significantly increased international normalized ratio (INR) associated with consumption of 50 ounces of grapefruit juice daily (12061). However, smaller amounts of grapefruit juice might not be a problem. In a small clinical trial, consumption of 24 ounces of grapefruit juice daily for one week had no effect on INR in males treated with warfarin (12063).
|
Theoretically, hesperidin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
Animal research suggests that hesperetin, a bioflavonoid aglycone derivative of hesperidin, may have antiplatelet activity (54822).
|
Theoretically, taking hesperidin with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, hesperidin may decrease the levels and clinical effects of celiprolol.
Details
Animal research shows that concomitant use of hesperidin may reduce the plasma area under the curve of celiprolol by up to 75% (91760). This effect has not been reported in humans.
|
Theoretically, concomitant use with CNS depressants may cause additive sedative effects.
Details
|
Theoretically, hesperidin may increase the levels and clinical effects of diltiazem.
Details
Animal research suggests that hesperidin may enhance the bioavailability of diltiazem, increasing the plasma area under the curve of diltiazem by up to 65.3% (91761). This effect has not been reported in humans.
|
Theoretically, hesperidin might inhibit P-glycoprotein-mediated drug efflux and potentially increase levels of drugs that are substrates of P-glycoprotein.
Details
In vitro research shows that hesperidin can inhibit P-glycoprotein efflux (54908). This effect has not been reported in humans.
|
Theoretically, hesperidin might increase the levels and clinical effects of verapamil.
Details
Animal research suggests that hesperidin may enhance the bioavailability of verapamil, increasing the plasma area under the curve of verapamil by 96.8% (91762). This effect has not been reported in humans
|
Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
Details
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage (110781).
|
Animal research shows that phenolics in lime juice inhibit cytochrome P450 3A4 (11976). This has been demonstrated in rats treated with sildenafil, a CYP3A4 substrate, and high doses of lime juice (110777).
|
Theoretically, concomitant use of lime oil with photosensitizing drugs may increase the risk of phototoxicity (11019).
|
Theoretically, sage might decrease the clinical effects of anticholinergic drugs.
Details
|
Theoretically, sage might interfere with the clinical effects of anticonvulsant drugs.
Details
Some species of sage can cause convulsions when consumed in large quantities (10812).
|
Theoretically, taking sage with antidiabetes drugs might increase the risk of hypoglycemia.
Details
In patients with polycystic ovary syndrome (PCOS) or inadequately controlled type 2 diabetes, common sage (Salvia officinalis) has demonstrated hypoglycemic activity (91971,103380). However, other clinical research in patients with inadequately controlled type 2 diabetes shows that common sage extract does not lower fasting blood glucose levels (105340).
|
Theoretically, sage might increase or decrease the effects of antihypertensive drugs.
Details
Animal research suggests that common sage (Salvia officinalis) can cause prolonged blood pressure reduction (4152). However, clinical research suggests that Spanish sage (Salvia lavandulaefolia) can increase blood pressure in some people with hypertension (10334). Until more is known, use with caution.
|
Theoretically, taking sage might increase the sedative and adverse effects of benzodiazepines.
Details

Details
Some constituents of sage have CNS depressant activity (10334).
|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP2C19 (10848). So far, this interaction has not been reported in humans.
|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP2C9.
Details
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP2C9 (10848). So far, this interaction has not been reported in humans.
|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP2D6.
Details
|
Theoretically, sage might decrease the levels and clinical effects of drugs metabolized by CYP2E1.
Details
Animal research suggests that drinking common sage (Salvia officinalis) tea increases the expression of CYP2E1 (72627). So far, this interaction has not been reported in humans.
|
Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP3A4.
Details
|
Theoretically, sage might interfere with hormone therapy.
Details
In vitro evidence suggests that geraniol, a constituent of Spanish sage (Salvia lavandulaefolia), exerts estrogenic activity (39572). The clinical significance of this effect is unclear.
|
Theoretically, sage might increase levels of drugs transported by P-glycoprotein.
Details
In vitro research suggests that common sage (Salvia officinalis) can inhibit the multi-drug transporter protein, P-glycoprotein (72641). This effect has not been reported in humans.
|
Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
Details
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (12115,17603,17604). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Details
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72% (7046,17604). In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31% (17605). Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine (17603). Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (7046). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
Details
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females (12154).
|
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Details
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (17603,17604). For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90% (7046,12115). Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours (17603,17604).
|
Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Details
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates (12116,15327). In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP) (7046,12115). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.
|
Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
Details
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice (14348). Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.
|
Calcium-fortified sweet orange juice might reduce quinolone absorption.
Details
|
In vitro, tangeretin, a constituent of tangerine, induces a 52% increase in the metabolism of midazolam by cytochrome P450 3A4 (CYP3A4) (28609). This suggests that tangeretin may stimulate CYP3A4 activity. However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam, a CYP3A4 substrate (28609). Theoretically, tangerine juice might increase CYP3A4 activity and decrease levels of drugs metabolized by this enzyme. However, this effect is unlikely.
Details
Some drugs metabolized by CYP3A4 include amitriptyline (Elavil), amiodarone (Cordarone), citalopram (Celexa), felodipine (Plendil), lansoprazole (Prevacid), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), and many others.
|
In vitro, tangeretin, a constituent of tangerine, appears to increase the metabolism of midazolam in human liver microsomes by up to 52% (28609). However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam (28609). Theoretically, tangerine juice might increase the metabolism and reduce the effects of midazolam. However, this effect is unlikely.

Below is general information about the adverse effects of the known ingredients contained in the product Menopause Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, black cohosh is generally well tolerated when used in typical doses.
Most Common Adverse Effects:
Orally: Breast tenderness, dizziness, gastrointestinal upset, headache, irritability, rash, tiredness.
Serious Adverse Effects (Rare):
Orally: Endometrial hyperplasia and hepatotoxicity, although data are conflicting for both.
Cardiovascular
...A single case of reversible bradycardia has been reported for a 59-year-old female who took one tablet of a specific black cohosh product (Remifemin, Schaper & Brümmer) daily for 2 weeks.
The adverse event was considered probably related to black cohosh use, although the exact mechanism by which black cohosh exerted this effect was unclear (35920).
There has been concern that, if black cohosh has estrogen-like effects, it could also potentially cause estrogen-like side effects including increased risk for thromboembolism and cardiovascular disease. These outcomes have not been specifically assessed in long-term trials; however, some research shows that a specific black cohosh extract (CimiPure, PureWorld) does not significantly affect surrogate markers for thromboembolism and cardiovascular risk such as fibrinogen, cholesterol, triglycerides, glucose, or insulin levels compared to placebo (16850).
Dermatologic ...Black cohosh has been associated with skin irritation and rashes (7054,10987,14330,15889,35853). A case report describes a patient who developed cutaneous pseudolymphoma 6 months after starting a specific black cohosh extract (Remifemin). Symptoms resolved within 12 weeks of discontinuing black cohosh (15890).
Gastrointestinal ...Orally, black cohosh can commonly cause gastrointestinal upset (4383,4615,4616,10988,13184,35824,35853,35965,103269,111714). Constipation and indigestion have also been reported (7054,35852).
Genitourinary
...Orally, black cohosh, including the specific black cohosh product Remifemin, may cause vaginal bleeding and breast tenderness in some postmenopausal patients (15889,35824).
However, the frequency of these events seems to be less than that of tibolone, a prescription hormone medication used to treat symptoms of menopause (15889,35904).
Due to the potential estrogen-like effects, there is concern that black cohosh might increase the risk of endometrial hyperplasia. However, a specific black cohosh extract CR BNO 1055 (Klimadynon/Menofem, Bionorica AG) does not appear to cause endometrial hyperplasia. Clinical research in postmenopausal adults shows that taking 40 mg daily of this extract for 12 weeks does not significantly increase superficial cells when compared with placebo, and causes significantly fewer superficial cells when compared with conjugated estrogens (Premarin) (14330). Additional clinical research shows that taking 40 mg daily of this extract for a year does not increase the risk of endometrial hyperplasia or endometrial thickening in postmenopausal adults (15036). Another specific combination product containing black cohosh extract plus St. John's wort (Gynoplus, Jin-Yang Pharm) also does not significantly increase superficial cells compared to placebo after 12 weeks of treatment (15893). Some patients taking tamoxifen plus black cohosh have experienced endometrial hyperplasia and vaginal bleeding. However, these effects are more likely due to tamoxifen than black cohosh (7054).
Hepatic
...There is concern that black cohosh might cause liver disease, hepatotoxicity, or hepatitis.
Adverse effects on the liver have not been documented in clinical studies. However, multiple case reports of liver toxicity, hepatitis, and abnormal liver function have been described in females taking black cohosh products alone or in combination with other herbs or drugs. In some cases, patients developed liver failure and required immediate liver transplantation (4383,10692,11909,12006,13144,14469,15160,16721,16722,16723) (16724,16727,35883,35888,35890,35895,89465,101592,107906). In one case, a female developed autoimmune hepatitis after 3 weeks of taking black cohosh. Symptoms resolved 2 weeks after discontinuing black cohosh (11906). In at least three cases, females have developed elevated liver enzymes and symptoms of hepatotoxicity after taking black cohosh products. Symptoms resolved and liver enzymes normalized within a week of discontinuing black cohosh (16725,16726). Analysis of two liver biopsies suggests that hepatotoxicity associated with black cohosh use results from the accumulation of 4HNE protein adducts in the cytoplasm of liver cells, which promotes the migration of lymphocytes to the affected area and induces an autoimmune response leading to troxis necrosis (89469).
However, many of these cases are poorly documented. Causality is possible based on some reports; however, other reports do not indicate that black cohosh is the probable cause of the events (15891,15892,16722,16723,16727,89465). Hepatitis can occur with no identifiable cause, raising the possibility that black cohosh and hepatitis might have been coincidental in some cases. Also, plant misidentification can occur, resulting in accidental substitution of a hepatotoxic plant (11910). Therefore, some experts argue that these cases do not provide conclusive evidence that black cohosh is responsible for liver disease (17085,35882,111634). Nonetheless, some countries require cautionary labeling on black cohosh products suggesting a risk of liver toxicity. The United States Pharmacopeia also recommends cautionary labeling on black cohosh products (16722). Until more is known about this potential risk, consider monitoring liver function in patients who take black cohosh.
Musculoskeletal
...One patient treated with black cohosh in a clinical trial discontinued treatment due to edema and arthralgia (35897).
Black cohosh has been linked to asthenia and muscle damage in one case. A 54-year-old female experienced asthenia with elevated creatinine phosphokinase (CPK) and lactate dehydrogenase (LDH) levels while taking black cohosh. The patient had taken a specific black cohosh extract (Remifemin) for 1 year, discontinued it for 2 months, restarted it, and then experienced symptoms 2 months later. Symptoms began to resolve 10 days after discontinuing black cohosh (14299).
Neurologic/CNS
...Orally, black cohosh may cause headache, dizziness, or tiredness (35852,35886).
There is one case report of seizures in a female who used black cohosh, evening primrose oil, and chasteberry (10988).
Also, there has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
In another case report, orobuccolingual dyskinesia, including tongue-biting, eating difficulties, and speech problems, was reported in a 46-year-old female who took two tablets containing black cohosh 20 mg and Panax ginseng 50 mg daily for 15 months. The patient's condition improved after stopping treatment with the herbs and taking clonazepam 2 mg daily with baclofen 40 mg daily (89735).
Ocular/Otic ...There is some concern that black cohosh might increase the risk of retinal vein thrombosis due to its estrogenic activity. In one case, a patient with protein S deficiency and systemic lupus erythematosus (SLE) experienced retinal vein thrombosis 3 days after taking a combination product containing black cohosh 250 mg, red clover 250 mg, dong quai 100 mg, and wild yam 276 mg (13155). It is unclear if this event was due to black cohosh, other ingredients, the combination, or another factor.
Oncologic ...There is some concern that black cohosh may affect hormone-sensitive cancers, such as some types of breast or uterine cancer, due to its potential estrogenic effects. However, evidence from a cohort study suggests that regular use of black cohosh is not associated with the risk of breast or endometrial cancer (17412,111634).
Psychiatric ...A 36-year-old female with a 15-year history of depression developed mania with psychotic and mixed features after taking a black cohosh extract 40 mg daily. The patient gradually recovered after stopping black cohosh and receiving treatment with antipsychotics (104517).
Pulmonary/Respiratory ...There has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
Renal ...There has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
Other ...While rare, weight gain has been reported in some patients taking black cohosh. However, in most cases the causality could not be established. A review of the literature, including published case reports, spontaneous reports to adverse event databases, and clinical trials, suggests that black cohosh does not cause weight gain (107907).
General ...Gamma-oryzanol is generally well tolerated. No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally, grapefruit and grapefruit juice are generally well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions in sensitive individuals have been reported. When large quantities are consumed, arrhythmias, mineralocorticoid excess, QT prolongation, and pseudohyperaldosteronism have been reported. There is also some concern for increased breast cancer risk with grapefruit consumption.
Cardiovascular ...Orally, consumption of pink grapefruit juice 1000 mL can cause QT prolongation and cause arrhythmias in healthy patients and worsen arrhythmias in cardiomyopathy patients (13031,91424).
Endocrine ...Orally, high doses of grapefruit juice have been observed to cause pseudohyperaldosteronism and mineralocorticoid excess (53340,53346).
Gastrointestinal ...In a case report, grapefruit juice held against the teeth resulted in enamel and tooth surface loss (53368).
Immunologic ...Orally, grapefruit can cause allergic sensitization characterized by eosinophilic gastroenteritis, urticaria, and generalized pruritus (53351,53360).
Oncologic ...Preliminary population research shows that postmenopausal adults who consume a quarter or more of a whole grapefruit daily have a 25% to 30% increased risk of developing breast cancer (14858). Grapefruit is a potent inhibitor of cytochrome P450 3A4, which metabolizes estrogen. Consuming large amounts of grapefruit might significantly increase endogenous estrogen levels and therefore increase the risk of breast cancer. More evidence is needed to validate these findings. Until more is known, advise patients to consume grapefruit in moderation.
Renal ...In population research, consumption of 240 mL/day of grapefruit juice is associated with an increased risk of kidney stones (4216,53372).
General ...Orally, hesperidin is generally well tolerated.
Dermatologic ...A case of recurrent allergic dermatitis was reported in a 70-year-old female with no known allergies who applied topical hesperidin methyl chalchone (94538).
Immunologic ...A case of recurrent allergic dermatitis was reported in a 70-year-old female with no known allergies who applied topical hesperidin methyl chalchone (94538).
General
...Orally, lemon is well tolerated in amounts commonly found in foods.
A thorough evaluation of safety outcomes has not been conducted on the use of larger amounts.
Most Common Adverse Effects:
Orally: Epigastralgia and heartburn with the regular consumption of fresh lemon juice.
Dermatologic ...Topically, the application of lemon oil might cause photosensitivity, due to furocoumarin derivative content. This occurs most often in fair-skinned people (11019).
Gastrointestinal ...Orally, fresh lemon juice, taken as 60 mL twice daily, has been reported to cause gastrointestinal disturbances in 37% of patients in one clinical trial, compared with 8% of patients in the placebo group. Specifically, of the patients consuming lemon juice, 21% experienced heartburn and 8% experienced epigastralgia, compared to 1% and 3%, respectively, in the placebo group (107489).
General
...Orally, lime juice may cause diarrhea or tooth sensitivity and wear, but these adverse effects are rare (59927,100123,100131).
Topically, lime oil and lime juice can cause allergic contact dermatitis (12,4058,100122,100132). Phytophotodermatitis is common when topical exposure to lime is followed by exposure to the sun (40894,59925,59928,100125,100126,100129).
Intravaginally, 20% to 100% lime juice can cause burning, dryness, pain, itching, erythema, edema, or abnormal bleeding (100127).
Dental ...Orally, tooth sensitivity and erosion of teeth have been reported for a woman who had consumed 150-300 mL of lime juice each night before bed for 3 years without brushing her teeth (100123). Tooth sensitivity has also been reported in a clinical trial (100131).
Dermatologic ...Topically, lime can cause phytophotodermatitis hours to days after exposure. Numerous case reports involve preparing or otherwise handling drinks containing lime slices or juice, often at beach bars where there is also sun exposure (40894,59925,59928,100125,100126,100129,113820). Exposure from the skin of others who have handled lime juice has also been reported (113818,113819). Symptoms include redness, swelling, bullae, and hyperpigmented red-brown macules which can take weeks to months to clear (100125,100126,100129,113819,113820). This photodermatitis is likely due to coumarins and furocoumarins, which are psoralen isomers (113819,113820).
Gastrointestinal ...Orally, diarrhea has been reported as an adverse effects in a clinical trial (59927).
Genitourinary ...Intravaginally, 20% lime juice has resulted in burning, dryness, erythema, and edema (100127). Higher doses of 25%, 50%, or 100% lime juice were dose-dependently related to vaginal, cervical, or vulval symptoms, especially pain, itching, and abnormal bleeding. The abnormal bleeding was most common in women that had applied 100% lime juice with a tampon. Peeling, erythema, discharge, and tenderness also occurred (100128).
Immunologic ...Topically, lime can rarely contribute to allergic contact dermatitis (4058,100122,100132).

Topically, sage extract sprayed into the mouth and throat can cause dryness or mild burning of the throat (72619).
Neurologic/CNS ...Orally, sage can cause dizziness or agitation (10810,17177). Thujone, a constituent of common sage (Salvia officinalis), is a neurotoxin and can cause seizures (10812,12868). Camphor and cineol, constituents of common sage and Spanish sage, can also cause neurotoxicity and seizures in high doses (10334,12868). Generalized tonic-clonic seizures have been reported in adults, children, and infants after ingestion of sage oil (12868,72666).
Pulmonary/Respiratory
...Orally, sage can cause wheezing (10810,17177).
Occupational exposure to sage dust can cause reduction in ventilatory capacity and chronic respiratory impairment (72672,72682,72686).
