Below is general information about the safety of the known ingredients contained in the product Insane Cutz. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Black pepper has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when black pepper oil is applied topically. Black pepper oil is nonirritating to the skin and is generally well tolerated (11). ...when black pepper oil is inhaled through the nose or as a vapor through the mouth, short-term. Black pepper oil as a vapor or as an olfactory stimulant has been used with apparent safety in clinical studies for up to 3 days and 30 days, respectively (29159,29160,29161,90502). There is insufficient reliable information available about the safety of black pepper when used orally in medicinal amounts.
CHILDREN: LIKELY SAFE
when used orally in amounts commonly found in foods (11).
CHILDREN: POSSIBLY UNSAFE
when used orally in large amounts.
Fatal cases of pepper aspiration have been reported in some patients (5619,5620). There is insufficient reliable information available about the safety of topical pepper oil when used in children.
PREGNANCY: LIKELY SAFE
when used orally in amounts commonly found in foods (11).
PREGNANCY: LIKELY UNSAFE
when used orally in large amounts.
Black pepper might have abortifacient effects (11,19); contraindicated. There is insufficient reliable information available about the safety of topical pepper when used during pregnancy.
LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (11).
There is insufficient reliable information available about the safety of black pepper when used in medicinal amounts during breast-feeding.
LIKELY SAFE ...when used orally, parenterally, or rectally and appropriately. Caffeine has Generally Recognized As Safe (GRAS) status in the US (4912,98806). Caffeine is also an FDA-approved product and a component of several over-the-counter and prescription products (4912,11832). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, doses of caffeine up to 400 mg daily are not associated with significant adverse cardiovascular, bone, behavioral, or reproductive effects in healthy adults (11733,98806). The US Dietary Guidelines Advisory Committee states that there is strong and consistent evidence that consumption of caffeine 400 mg daily is not associated with increased risk of major chronic diseases, such as cardiovascular disease or cancer, in healthy adults (98806). This amount of caffeine is similar to the amount of caffeine found in approximately 4 cups of coffee. Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
POSSIBLY UNSAFE ...when used orally, long-term or in high doses (91063). Chronic use, especially in large amounts, can produce tolerance, habituation, psychological dependence, and other adverse effects (3719). Acute use of high doses, typically above 400 mg daily, has been associated with significant adverse effects such as tachyarrhythmia and sleep disturbances (11832). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
LIKELY UNSAFE ...when used orally in very high doses. The fatal acute oral dose of caffeine is estimated to be 10-14 grams (150-200 mg/kg). Serious toxicity can occur at lower doses depending on variables in caffeine sensitivity such as smoking, age, or prior caffeine use (11832,95700,97454,104573). Caffeine products sold to consumers in highly concentrated or pure formulations are considered to a serious health concern because these products have a risk of being used in very high doses. Concentrated liquid caffeine can contain about 2 grams of caffeine in a half cup. Powdered pure caffeine can contain about 3.2 grams of caffeine in one teaspoon. Powdered pure caffeine can be fatal in adults when used in doses of 2 tablespoons or less. As of 2018, these products are considered by the FDA to be unlawful when sold to consumers in bulk quantities (95700).
CHILDREN: POSSIBLY SAFE
when used orally or intravenously and appropriately in neonates under the guidance of a healthcare professional (6371,38340,38344,91084,91087,97452).
...when used orally in amounts commonly found in foods and beverages in children and adolescents (4912,11833,36555). Daily intake of caffeine in doses of less than 2.5 mg/kg daily are not associated with significant adverse effects in children and adolescents (11733,98806). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
PREGNANCY: POSSIBLY SAFE
when used orally in amounts commonly found in foods.
Intakes of caffeine should be monitored during pregnancy. Caffeine crosses the human placenta, but is not considered a teratogen (38048,38252,91032). Fetal blood and tissue levels are similar to maternal concentrations (4260). The use of caffeine during pregnancy is controversial; however, moderate consumption has not been associated with clinically important adverse fetal effects (2708,2709,2710,2711,9606,16014,16015,98806,108814). In some studies consuming amounts over 200 mg daily is associated with a significantly increased risk of miscarriage (16014,37960). This increased risk seems to occur in those with genotypes that confer a slow rate of caffeine metabolism (98806). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, up to 300 mg daily can be consumed during pregnancy without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations (11733,98806). However, observational research in a Norwegian cohort found that caffeine consumption is associated with a 16% increased odds of the baby being born small for gestational age when compared with no consumption (100369,103707). The same Norwegian cohort found that low to moderate caffeine consumption during pregnancy is not associated with changes in neurodevelopment in children up to 8 years of age (103699). Advise patients to keep caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of coffee or tea.
PREGNANCY: POSSIBLY UNSAFE
when used orally in amounts over 300 mg daily.
Caffeine crosses the placenta, producing fetal blood concentrations similar to maternal levels (4260,98806). Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies (16014,98806). Advise patients to keep caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of coffee or tea. Additionally, high doses of caffeine throughout pregnancy have resulted in symptoms of caffeine withdrawal in newborn infants (9891). High doses of caffeine have also been associated with spontaneous abortion, premature delivery, and low birth weight (2709,2711,91033,91048,95949). In a cohort of mother/infant pairs with a median maternal plasma caffeine level of 168.5 ng/mL (range 29.5-650.5 ng/mL) during pregnancy, birth weights and lengths were lower in the 4th quartile of caffeine intake compared with the 1st. By age 7, heights and weights were lower by 1.5 cm and 1.1 kg respectively. In another cohort of mother/infant pairs with higher maternal pregnancy plasma caffeine levels, median 625.5 ng/mL (range 86.2 to 1994.7 ng/mL), heights at age 8 were 2.2 cm lower, but there was no difference in weights (109846).
LACTATION: POSSIBLY SAFE
when used orally in amounts commonly found in foods.
Caffeine intake should be closely monitored while breast-feeding. During lactation, breast milk concentrations of caffeine are thought to be approximately 50% of serum concentrations and caffeine peaks in breastmilk approximately 1-2 hours after consumption (23590).
LACTATION: POSSIBLY UNSAFE
when used orally in large amounts.
Caffeine is excreted slowly in infants and may accumulate. Caffeine can cause sleep disturbances, irritability, and increased bowel activity in breast-fed infants exposed to caffeine (2708,6026).
LIKELY SAFE ...when used orally in amounts commonly found in foods. Dandelion has Generally Recognized As Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts (12).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using amounts greater than those in foods.
POSSIBLY UNSAFE ...when used orally. In one clinical study, 4 out of 10 patients taking Rauvolfia vomitoria dried root powder 300-800 mg daily for 6 weeks developed extrapyramidal symptoms including tremor, akathisia, hypokinesia, and dystonia. Two cases were severe enough to warrant treatment with antiparkinsonian medications (95991). Rauvolfia vomitoria also contains small amounts of the drugs reserpine and yohimbine. These constituents may cause serious adverse effects including bradycardia, hypertension or hypotension, irregular heartbeat, myocardial infarction, seizures, and depression (94328). There is insufficient reliable information available about the safety of Rauvolfia vomitoria when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Animal research suggests that Rauvolfia vomitoria has teratogenic effects (93434,93435,93436).

Below is general information about the interactions of the known ingredients contained in the product Insane Cutz. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Details
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin (29269). This has not been reported in humans.
|
Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
Details

|
Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
Details
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects (16833). In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner (103819).
|

|
Theoretically, black pepper might increase levels of P-glycoprotein substrates.
Details
|
Theoretically, black pepper might increase the sedative effects of pentobarbital.
Details
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time (29214).
|
Black pepper might increase blood levels of phenytoin.
Details
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin (537,14442). Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin (14375). Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper (14442).
|
Black pepper might increase blood levels of propranolol.
Details
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol (538).
|
Black pepper might increase blood levels of rifampin.
Details
|
Black pepper might increase blood levels of theophylline.
Details
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline (538).
|
Theoretically, caffeine might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Details
Some evidence shows that caffeine is a competitive inhibitor of adenosine and can reduce the vasodilatory effects of adenosine in humans (38172). However, other research shows that caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine (11771). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing (11771).
|
Theoretically, concomitant use might increase levels and adverse effects of caffeine.
Details
Alcohol reduces caffeine metabolism. Concomitant use of alcohol can increase caffeine serum concentrations and the risk of caffeine adverse effects (6370).
|

Details
|
Theoretically, taking caffeine with antidiabetes drugs might interfere with blood glucose control.
Details
|
Theoretically, large amounts of caffeine might increase the cardiac inotropic effects of beta-agonists (15).
|
Theoretically, caffeine might reduce the effects of carbamazepine and increase the risk for convulsions.
Details
Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when taken in doses above 400 mg/kg (23559,23561). Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine 2-fold in healthy individuals (23562).
|
Theoretically, cimetidine might increase the levels and adverse effects of caffeine.
Details
Cimetidine decreases the rate of caffeine clearance by 31% to 42% (11736).
|
Caffeine might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Details
Caffeine might increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg per day inhibit clozapine metabolism (5051). Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Although researchers speculate that caffeine might inhibit CYP1A2, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients more sensitive to an interaction between clozapine and caffeine (13741). In one case report, severe, life-threatening clozapine toxicity and multiorgan system failure occurred in a patient with schizophrenia stabilized on clozapine who consumed caffeine 600 mg daily (108817).
|
Theoretically, contraceptive drugs might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, caffeine might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Details
Caffeine inhibits dipyridamole-induced vasodilation (11770,11772). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing (11771).

|
Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, caffeine might reduce the effects of ethosuximide and increase the risk for convulsions.
Details

Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Details
Caffeine has been shown to inhibit monoamine oxidase (MAO) A and B in laboratory studies (37724,37877,37912,38108). Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis (15). In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension (91086). Hypertension was resolved after the patient switched to drinking decaffeinated coffee.
|
Theoretically, concomitant use might increase the risk of hypertension.
Details

Details
|
Theoretically, caffeine might reduce the effects of phenytoin and increase the risk for convulsions.
Details
|
Theoretically, caffeine might increase the levels and clinical effects of pioglitazone.
Details
Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone (108812). However, the exact mechanism of this interaction is unclear.
|
Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Details
Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce the metabolism of one or both agents (11739).
|
Theoretically, concomitant use might increase stimulant adverse effects.
Details
Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects (11832).
|
Theoretically, terbinafine might increase the levels and adverse effects of caffeine.
Details
Terbinafine decreases the clearance of intravenous caffeine by 19% (11740).
|
Theoretically, caffeine might increase the levels and adverse effects of theophylline.

|
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Details
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion (13474,90926). Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion (46960).
|
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Details
Laboratory research suggests that dandelion might inhibit CYP1A2 (12734). So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
|
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
Details
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme (12734).
|
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Details
Animal research suggests that dandelion has diuretic properties (13475). As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
|
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Details
Dandelion contains significant amounts of potassium (13465).
|
Theoretically, dandelion might lower fluoroquinolone levels.

|
Theoretically, combining Rauvolfia vomitoria with antiplatelet or anticoagulant drugs might have additive effects.
Details
Rauvolfia vomitoria contains small amounts of yohimbine. Research in healthy adults shows that taking yohimbine in doses of 8 mg or more seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor (86773,86806,86835,86853). The effects of Rauvolfia vomitoria itself are unclear.
|
Theoretically, taking Rauvolfia vomitoria with antidiabetes drugs might increase the risk of hypoglycemia.

|
Theoretically, Rauvolfia vomitoria might alter the effects and side effects of ephedrine.
Details
Rauvolfia vomitoria contains resperine, which might reduce indirect-sympathomimetic drug activity. However, another constituent of Rauvolfia vomitoria, yohimbine, has stimulant activity and may increase the risk of adverse effects with ephedrine (15).
|
Theoretically, Rauvolfia vomitoria might reduce the effects of levodopa.
Details
|
Theoretically, concomitant use might cause additive effects.
Details
|
Theoretically, concomitant use might cause additive effects.
Details
|
Theoretically, concomitant use might alter the effects of Rauvolfia vomitoria and increase the risk for adverse effects.
Details
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine, a constituent of Rauvolfia vomitoria, 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor (105881). Also, concomitant use of TCAs with Rauvolfia vomitoria may decrease the effects of rauwolfia alkaloids (15).

Below is general information about the adverse effects of the known ingredients contained in the product Insane Cutz. 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 pepper seems to be well tolerated when used in the amounts found in food or when taken as a medicine as a single dose.
Topically and as aromatherapy, black pepper oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Burning aftertaste, dyspepsia, and reduced taste perception.
Inhalation: Cough.
Serious Adverse Effects (Rare):
Orally: Allergic reaction in sensitive individuals.
Gastrointestinal ...Orally, black pepper can cause a burning aftertaste (5619) and dyspepsia (38061). Single and repeated application of piperine, the active constituent in black pepper, to the tongue and oral cavity can decrease taste perception (29267). By intragastric route, black pepper 1.5 grams has been reported to cause gastrointestinal microbleeds (29164). It is not clear if such an effect would occur with oral administration.
Immunologic ...In one case report, a 17-month-old male developed hives, red eyes, facial swelling, and a severe cough following consumption of a sauce containing multiple ingredients. Allergen skin tests were positive to both black pepper and cayenne, which were found in the sauce (93947).
Ocular/Otic ...Topically, ground black pepper can cause redness of the eyes and swelling of the eyelids (5619).
Pulmonary/Respiratory ...When inhaled through the nose as an olfactory stimulant, black pepper oil has been reported to cause cough in one clinical trial (29162).
General
...Caffeine in moderate doses is typically well tolerated.
Most Common Adverse Effects:
Orally: Anxiety, dependence with chronic use, diarrhea, diuresis, gastric irritation, headache, insomnia, muscular tremors, nausea, and restlessness.
Serious Adverse Effects (Rare):
Orally: Stroke has been reported rarely.
Cardiovascular
...Caffeine can temporarily increase blood pressure.
Usually, blood pressure increases 30 minutes after ingestion, peaks in 1-2 hours, and remains elevated for over 4 hours (36539,37732,37989,38000,38300).
Although acute administration of caffeine can cause increased blood pressure, regular consumption does not seem to increase either blood pressure or pulse, even in mildly hypertensive patients (1451,1452,2722,38335). However, the form of caffeine may play a role in blood pressure increase after a more sustained caffeine use. In a pooled analysis of clinical trials, coffee intake was not associated with an increase in blood pressure, while ingesting caffeine 410 mg daily for at least 7 days modestly increased blood pressure by an average of 4.16/2.41 mmHg (37657). Another meta-analysis of clinical research shows that taking caffeine increases systolic and diastolic blood pressure by approximately 2 mmHg when compared with control. Preliminary subgroup analyses suggest that caffeine may increase blood pressure more in males or at doses over 400 mg (112738).
When used prior to intensive exercise, caffeine can increase systolic blood pressure by 7-8 mmHg (38308). The blood pressure-raising effects of caffeine are greater during stress (36479,38334) and after caffeine-abstinence of at least 24 hours (38241).
Epidemiological research suggests there is no association of caffeine consumption with incidence of hypertension (38190). Habitual coffee consumption also doesn't seem to be related to hypertension, but habitual consumption of sugared or diet cola is associated with development of hypertension (13739).
Epidemiological research has found that regular caffeine intake of up to 400 mg daily is not associated with increased incidence of atrial fibrillation (38018,38076,91028,91034,97451,97453,103708), atherosclerosis (38033), cardiac ectopy (91127), stroke (37804), ventricular arrhythmia (95948,97453), and cardiovascular disease in general (37805,98806). One clinical trial shows that in adults with diagnosed heart failure, consumption of 500 mg of coffee does not result in an increased risk for arrhythmia during exercise (95950). However, caffeine intake may pose a greater cardiovascular risk to subjects that are not regular users of caffeine. For example, in one population study, caffeinated coffee consumption was associated with an increased risk of ischemic stroke in subjects that don't regularly drink coffee (38102). In a population study in Japanese subjects, caffeine-containing medication use was modestly associated with hemorrhagic stroke in adults that do not consume caffeine regularly (91059).
The most common side effect of caffeine in neonates receiving caffeine for apnea is tachycardia (98807).
Dermatologic ...There are several case reports of urticaria after caffeine ingestion (36546,36448,36475).
Endocrine
...Some evidence shows caffeine is associated with fibrocystic breast disease or breast cancer in females; however, this is controversial since findings are conflicting (8043,108806).
Restricting caffeine in females with fibrocystic breast conditions doesn't seem to affect breast nodularity, swelling, or pain (8996). A population analysis of the Women's Health Initiative observational study has found no association between consumption of caffeine-containing beverages and the incidence of invasive breast cancer in models adjusted for demographic, lifestyle, and reproductive factors (108806). Also, a dose-response analysis of 2 low-quality observational studies has found that high consumption of caffeine is not associated with an increased risk of breast cancer (108807).
Clinical research in healthy adults shows that an increase consumption of caffeine results in increased insulin resistance (91023).
Gastrointestinal ...Gastrointestinal upset, nausea, diarrhea, abdominal pain, and fecal incontinence may occur with caffeine intake (36466,37755,37806,37789,37830,38138,38136,38223,95956,95963). Also, caffeine may cause feeding intolerance and gastrointestinal irritation in infants (6023). Perioperative caffeine during cardiopulmonary bypass surgery seems to increase the rate of postoperative nausea and vomiting (97451). Caffeine and coffee consumption have been associated with an increase in the incidence of heartburn (37545,37575,38251,38259,38267) and gastrointestinal esophageal reflux disease (GERD) (38329,37633,37631,37603).
Genitourinary ...Caffeine, a known diuretic, may increase voiding, give a sense of urgency, and irritate the bladder (37874,37961,104580). In men with lower urinary tract symptoms, caffeine intake increased the risk of interstitial cystitis/painful bladder syndrome (38115). Excessive caffeine consumption may worsen premenstrual syndrome. Consumption of up to 10 cups of caffeinated drinks daily was associated with increased severity of premenstrual syndrome (38177). Finally, population research shows that exposure to caffeine was not associated with an increased risk of endometriosis (91035).
Immunologic ...Caffeine can cause anaphylaxis in sensitive individuals, although true IgE-mediated caffeine allergy seems to be relatively rare (11315).
Musculoskeletal
...Caffeine can induce or exacerbate muscular tremors (38136,37673,38161).
There has also been a report of severe rhabdomyolysis in a healthy 40-year-old patient who consumed an energy drink containing 400 mg of caffeine (4 mg/kg) and then participated in strenuous weightlifting exercise (108818).
Epidemiological evidence regarding the relationship between caffeine use and the risk for osteoporosis is contradictory. Caffeine can release calcium from storage sites and increase its urinary excretion (2669,10202,11317,111489). Females with a genetic variant of the vitamin D receptor appear to be at an increased risk for the detrimental effect of caffeine on bone mass (2669). However, moderate caffeine intake, less than 300 mg daily, does not seem to significantly increase osteoporosis risk in most postmenopausal adults with normal calcium intake (2669,6025,10202,11317). Premature infants treated with intravenous caffeine for apnea of prematurity, have a lower bone mineral content compared with infants who are not treated with caffeine, especially when treatment extends beyond 14 days (111489).
Neurologic/CNS ...Caffeine can cause headaches, anxiety, jitteriness, restlessness, and nervousness (36466,37694,37755,37806,37865,37830,37889,38223,95952). In adolescents, there is an inverse correlation between the consumption of caffeine and various measurements of cognitive function (104579). Insomnia is a frequent adverse effect in children (10755). Caffeine may result in insomnia and sleep disturbances in adults as well (36445,36483,36512,36531,37598,37795,37819,37862,37864,37890)(37968,37971,38091,38242,91022,92952). Additionally, caffeine may exacerbate sleep disturbances in patients with acquired immunodeficiency syndrome (AIDS) (10204). Combining ephedra with caffeine can increase the risk of adverse effects. Jitteriness, hypertension, seizures, temporary loss of consciousness, and hospitalization requiring life support has been associated with the combined use of ephedra and caffeine (2729). Finally, epidemiological research suggests that consuming more than 190 mg of caffeine daily is associated with an earlier onset of Huntington disease by 3.6 years (91078).
Ocular/Otic
...In individuals with glaucoma, coffee consumption and caffeine intake has been found to increase intraocular pressure (8540,36464,36465,37670).
The magnitude of this effect seems to depend on individual tolerance to caffeine. Some research in healthy young adults shows that caffeine increases intraocular pressure to a greater degree in low-consumers of caffeine (i.e., 1 cup of coffee or less daily) when compared to high-consumers (i.e., those consuming 2 cups of coffee or more daily) (100371). The peak increase of intraocular pressure seems to occur at about 1.5 hours after caffeine ingestion, and there is no notable effect 4 hours after ingestion (36462,100371).
Oncologic ...Most human studies which have examined caffeine or methylxanthine intake have found that they do not play a role in the development of various cancers, including breast, ovarian, brain, colon, rectal, or bladder cancer (37641,37737,37775,37900,38050,38169,38220,91054,91076,108806).
Psychiatric
...Caffeine may lead to habituation and physical dependence (36355,36453,36512,36599), with amounts as low as 100 mg daily (36355,36453).
An estimated 9% to 30% of caffeine consumers could be considered addicted to caffeine (36355). Higher doses of caffeine have caused nervousness, agitation, anxiety, irritability, delirium, depression, sleep disturbances, impaired attention, manic behavior, psychosis and panic attacks (36505,37717,37818,37839,37857,37982,38004,38017,38028,38072)(38079,38138,38306,38325,38331,38332,97464). Similar symptoms have been reported in a caffeine-naïve individual experiencing fatigue and dehydration after a dose of only 200 mg, with resolution of symptoms occurring within 2 hours (95952).
Withdrawal: The existence or clinical importance of caffeine withdrawal is controversial. Some researchers think that if it exists, it appears to be of little clinical significance (11839). Headache is the most common symptom, due to cerebral vasodilation and increased blood flow (37769,37991,37998). Other researchers suggest symptoms such as tiredness and fatigue, decreased energy, alertness and attentiveness, drowsiness, decreased contentedness, depressed mood, difficulty concentration, irritability, and lack of clear-headedness are typical of caffeine withdrawal (13738). Withdrawal symptoms typically occur 12-24 hours after the last dose of caffeine and peak around 48 hours (37769,36600). Symptoms may persist for 2-9 days. Withdrawal symptoms such as delirium, nausea, vomiting, rhinorrhea, nervousness, restlessness, anxiety, muscle tension, muscle pains, and flushed face have been described. However, these symptoms may be from nonpharmacological factors related to knowledge and expectation of effects. Clinically significant symptoms caused by caffeine withdrawal may be uncommon (2723,11839). In a case report, caffeine consumption of 560 mg daily was associated with increased suicidality (91082).
Renal ...Data on the relationship between caffeine intake and kidney stones are conflicting. Some clinical research shows that caffeine consumption may increase the risk of stone formation (37634,111498), while other research shows a reduced risk with increasing caffeine intakes (111498). A meta-analysis of 7 studies found that overall, there is an inverse relationship, with a 32% decrease in the risk of kidney stones between the lowest and highest daily intakes of caffeine (111498).
Other ...People with voice disorders, singers, and other voice professionals are often advised against the use of caffeine; however, this recommendation has been based on anecdotal evidence. One small exploratory study suggests that caffeine ingestion may adversely affect subjective voice quality, although there appears to be significant intra-individual variability. Further study is necessary to confirm these preliminary findings (2724).
General
...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether dandelion, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Dermatologic ...Topically, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.
Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diurectic, laxative, cholagogue, and antirheumatic properties (46959).
Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).
General
...Orally, Rauvolfia vomitoria is possibly unsafe due to the potential for serious adverse effects from its reserpine and yohimbine constituents.
Serious Adverse Effects (Rare):
Orally: Akathisia, dystonia, hypokinesia, and tremor.
Cardiovascular
...Orally, drinking a beverage made by boiling Rauvolfia vomitoria foliage with bitter orange fruit can reduce levels of high-density lipoprotein (HDL) cholesterol in patients with diabetes.
The effect of Rauvolfia vomitoria alone is unclear (35751).
Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might also cause some of the adverse effects associated with these constituents. Adverse reactions to reserpine have included angina-like symptoms (94328). At high doses, adverse effects related to yohimbine have included hypertension (17645,86801,91521), tachycardia or palpitations (3312,17465), and myocardial infarction or atrial fibrillation (17465).
Dermatologic ...Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might also cause some of the adverse effects associated with these constituents. Orally, low amounts of reserpine may cause adverse reactions including facial flushing, skin rash, and itching (94328). Yohimbine may cause rash, erythrodermic skin eruption, and exanthema (3312,3971,86878,86896).
Endocrine ...Since Rauvolfia vomitoria contains small amounts of reserpine, theoretically it might cause some of the adverse effects associated with this constituent. Orally, low amounts of reserpine may cause adverse reactions including galactorrhea or breast enlargement (94328).
Gastrointestinal ...Since Rauvolfia vomitoria contains small amounts of yohimbine, theoretically it might cause some of the adverse effects associated with this constituent. Yohimbine has been reported to cause nausea, vomiting, increased salivation, diarrhea, and gastrointestinal distress (3970,17465,86780,86786,86804,86827,86896).
Genitourinary ...Since Rauvolfia vomitoria contains small amounts of yohimbine, theoretically it might cause some of the adverse effects associated with this constituent. Orally, yohimbine may cause dartos contraction or decreased libido in some patients (86786,86882).
Hematologic ...Since Rauvolfia vomitoria contains small amounts of yohimbine, theoretically it might cause some of the adverse effects associated with this constituent. A case of drug-induced agranulocytosis has been reported following prolonged use of oral yohimbine (86877).
Immunologic ...Since Rauvolfia vomitoria contains small amounts of yohimbine, theoretically it might cause some of the adverse effects associated with this constituent. There is one report of a hypersensitivity reaction including fever; chills; malaise; itchy, scaly skin; progressive renal failure; and lupus-like syndrome associated with ingestion of a one-day dose of yohimbine (6169).
Musculoskeletal ...Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might cause some of the adverse effects associated with these constituents. Orally, low amounts of reserpine may cause edema (94328). Orally, yohimbine may cause muscle aches (86850).
Neurologic/CNS
...Orally, Rauvolfia vomitoria has been associated with the development of extrapyramidal symptoms in some patients.
In one clinical study, 4 out of 10 patients who were taking Rauvolfia vomitoria dried root 300-800 mg daily developed extrapyramidal symptoms, including tremor, akathisia, hypokinesia, and dystonia. Two cases were severe enough to warrant treatment with antiparkinsonian medications (95991).
Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might also increase the risk of adverse effects associated with these constituents. Doses of reserpine of greater than 0.5 mg daily appear to increase the risk of side effects. In extremely large amounts, Parkinson-like symptoms, extrapyramidal reactions, and convulsions may occur (15,94328,94332). Orally, yohimbine has been associated with reports of tremulousness, head twitching, seizures, loss of consciousness, enhanced brain norepinephrine release, decreased energy, dizziness, vertigo, headache, feeling cold, flushing, diaphoresis, and paralysis (11,18,3312,3971,17465,86786,86801,86804,86827,86896).
Oncologic ...Since Rauvolfia vomitoria contains small amounts of reserpine, theoretically it might increase the risk of adverse effects associated with this constituent. Some preliminary research suggested a possible relationship between reserpine products and an increased risk of breast cancer; however, further analysis found that use of reserpine products is not associated with an increased risk of breast cancer (94328).
Psychiatric ...In one clinical study, Rauvolfia vomitoria dried root 300-800 mg orally daily for 6 weeks was not associated with reports of depression or thoughts of suicide in patients with psychosis (95991). However, since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might cause some of the adverse effects associated with these constituents. Orally, low amounts of reserpine may cause nightmares, drowsiness, fatigue, lethargy, and slowed reflexes. In larger amounts, depression may develop. After discontinuation of reserpine, mental depression may persist for several months. Doses of reserpine of greater than 0.5 mg daily appear to increase the risk of these side effects. Orally, yohimbine may increase malaise, fatigue, insomnia, restlessness, agitation, and anxiety (3312,3970,3971,17465,86786,86801,86804,86822,86827,86834) (86868,86878,86882,86896).
Pulmonary/Respiratory ...Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might cause some of the adverse effects associated with these constituents. Orally, reserpine may cause nasal congestion or bronchospasm (15,94328). Allergic reactions may also occur; while these events are rare, they may precipitate asthma (15,94328). Orally, yohimbine may cause bronchospasm, tachypnea, cough, sinusitis, and rhinorrhea (17465,86825,86850,94112). Excessive doses of yohimbine can cause respiratory depression (1118).
Renal ...Since Rauvolfia vomitoria contains small amounts of yohimbine, theoretically it might cause some of the adverse effects associated with this constituent. A case of acute kidney failure related to yohimbine-induced systemic lupus erythematosus has been reported (6169).
