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 and appropriately (13161,14306,14307,14308,15655,15752,17187,92271,92274,103247)(103250,108898). However, cocoa naturally contains caffeine, and caffeine may be unsafe when used orally in doses of more than 400 mg daily (11733,98806). While most cocoa products contain only small amounts of caffeine (about 2-35 mg per serving) (2708,3900), one cup of unsweetened, dry cocoa powder can contain up to 198 mg of caffeine (100515). To be on the safe side, cocoa should be used in amounts that provide less than 400 mg of caffeine daily. Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine naturally found in ingredients such as cocoa does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product. Cocoa and dark chocolate products worldwide also contain heavy metals such as lead and cadmium. In the US, one ounce (approximately 28 grams) of most commercially available dark chocolate products tested contained levels of lead and/or cadmium above the maximum allowable dose level for California, with cadmium levels generally increasing with the percentage of cocoa (109847,109848,109849). Advise patients to consume cocoa in moderation. ...when used topically. Cocoa butter is used extensively as a base for ointments and suppositories and is generally considered safe (11).
CHILDREN: POSSIBLY UNSAFE
when dark chocolate is used orally.
Cocoa and dark chocolate products worldwide contain heavy metals such as lead and cadmium. In the US, one ounce (approximately 28 grams) of most commercially available dark chocolate products tested contained levels of lead and/or cadmium above the maximum allowable dose level for California, with cadmium levels generally increasing with the percentage of cocoa (109847,109848,109849). Children are at increased risk of adverse effects from intake of lead and/or cadmium. There is insufficient reliable information available about the safety of other chocolate-based products that typically contain smaller quantities of cocoa.
PREGNANCY: POSSIBLY SAFE
when used orally in moderate amounts.
However, due to the caffeine content of cocoa preparations, intake should be closely monitored during pregnancy to ensure moderate consumption. Fetal blood concentrations of caffeine approximate maternal concentrations (4260). Some research has found that intrauterine exposure to even modest amounts of caffeine, based on maternal blood levels during the first trimester, is associated with a shorter stature in children ages 4-8 years (109846). While many cocoa products contain only small amounts of caffeine (about 2-35 mg per serving) (2708,3900), unsweetened, dry cocoa powder can contain up to 198 mg of caffeine per cup (100515). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, doses of up to 300 mg daily can be consumed during pregnancy without an increased risk of spontaneous abortion, still birth, preterm birth, fetal growth retardation, or congenital malformations (11733,98806). To be on the safe side, cocoa should be used in amounts that provide less than 300 mg of caffeine daily. Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine found in ingredients such as cocoa, which naturally contains caffeine, does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
PREGNANCY: POSSIBLY UNSAFE
when used orally in large amounts.
Caffeine found in cocoa crosses the placenta producing fetal blood concentrations similar to maternal levels (4260). Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies (16014,98806). Additionally, high intake of caffeine during pregnancy have been associated with premature delivery, low birth weight, and loss of the fetus (6). While many cocoa products contain only small amounts of caffeine (about 2-35 mg per serving) (2708,3900), unsweetened, dry cocoa powder can contain up to 198 mg of caffeine per cup (100515). To be on the safe side, cocoa should be used in amounts that provide less than 300 mg of caffeine daily (2708). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine found in ingredients such as cocoa, which naturally contains caffeine, does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product. Cocoa and dark chocolate products worldwide also contain heavy metals such as lead and cadmium. In the US, one ounce (approximately 28 grams) of most commercially available dark chocolate products tested contained levels of lead and/or cadmium above the maximum allowable dose level for California, with cadmium levels generally increasing with the percentage of cocoa (109847,109848,109849). Large doses or excessive intake of cocoa should be avoided during pregnancy.
LACTATION: POSSIBLY SAFE
when used in moderate amounts or in amounts commonly found in foods.
Due to the caffeine content of cocoa preparations, intake should be closely monitored while breastfeeding. During lactation, breast milk concentrations of caffeine are thought to be approximately 50% of serum concentrations. Moderate consumption of cocoa would likely result in very small amounts of caffeine exposure to a nursing infant (6). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine found in ingredients such as cocoa, which naturally contains caffeine, does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
LACTATION: POSSIBLY UNSAFE
when used orally in large amounts.
Consumption of excess chocolate (16 oz per day) may cause irritability and increased bowel activity in the infant (6026). Cocoa and dark chocolate products worldwide also contain heavy metals such as lead and cadmium. In the US, one ounce (approximately 28 grams) of most commercially available dark chocolate products tested contained levels of lead and/or cadmium above the maximum allowable dose level for California, with cadmium levels generally increasing with the percentage of cocoa (109847,109848,109849). Large doses or excessive intake of cocoa should be avoided during lactation.
LIKELY SAFE ...when used orally in amounts commonly found in foods. The typical diet supplies 2-24 mg of diindolylmethane daily (7170,7176,7664).
POSSIBLY SAFE ...when used orally and appropriately in medicinal doses. Diindolylmethane has been used with apparent safety at a dose of 45 mg daily for up to 6 months or at a higher dose of 100-140 mg daily for up to 3 months (47709,47729,93836,103830).

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
 Details
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals (391). However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.

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).

Diindolylmethane might have mild estrogenic or antiestrogenic effects (7664). Theoretically, large amounts of diindolylmethane might interfere with hormone replacement therapy.
|
In vitro evidence suggests that some methoxylated flavones have antiplatelet effects (12079,12083). Theoretically, methoxylated flavones might additive effects when used with anticoagulant or antiplatelet drugs.
Details
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
|
Some in vitro evidence suggests that methoxylated flavones might induce CYP1A2, possibly by increasing gene transcription (12078). However, other in vitro research has not shown this effect (100676). So far this interaction has not been reported in humans. Theoretically, concurrent use of methoxylated flavones and drugs metabolized by CYP1A2 might increase drug metabolism, decrease serum levels, and reduce effectiveness.

In vitro evidence suggests that methoxylated flavones might inhibit cytochrome P450 3A4 (CYP3A4). This effect seems to be structure-dependent, and does not occur with all methoxylated flavones (100676). So far this interaction has not been reported in humans. Theoretically, concurrent use of certain methoxylated flavones with drugs metabolized by CYP3A4 might result in increased drug levels and an increased risk for adverse effects.
Details
Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), Pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline (Slo-bid, Theo-Dur, others), zileuton (Zyflo), Zolmitriptan (Zomig), and others.

In vitro, methoxylated flavones inhibit organic anion transporting polypeptide (OATP) 1B1, 1B3, and 2B1 (106331). This may reduce the bioavailability of oral drugs that are substrates of OATP. However, this interaction has not been reported in humans.
|
In vitro evidence shows that some methoxylated flavones including tangeretin, nobiletin, and heptamethoxyflavone, inhibit P-glycoprotein (15327,94025). Theoretically, these methoxylated flavones might increase absorption and blood levels of drugs that are transported by P-glycoprotein.
Details
Some of these drugs include some chemotherapeutic agents (daunorubicin, docetaxel, etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir, saquinavir), H2 antagonists (cimetidine, ranitidine), some calcium channel blockers (diltiazem, verapamil), corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.

Resveratrol might increase levels of drugs metabolized by CYP2E1.
Details
In vitro research suggests that resveratrol inhibits CYP2E1 isoenzyme (7864,70896). Also, a pharmacokinetic study shows that taking resveratrol 500 mg daily for 10 days prior to taking a single dose of chlorzoxazone 250 mg increases the maximum concentration of chlorzoxazone by about 54%, the area under the curve of chlorzoxazone by about 72%, and the half-life of chlorzoxazone by about 35% (95824). Chlorzoxazone is used as a probe drug for CYP2E1.

Below is general information about the adverse effects of the known ingredients contained in the product Immortal-RX. 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
...Alpha-lipoic acid appears to be generally well tolerated when used orally, intravenously, or topically.
Most Common Adverse Effects:
Orally: Headache, heartburn, nausea, and vomiting.
Topically: Irritation and rash.
Intravenously: Nausea and vomiting.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about insulin autoimmune syndrome (IAS).
Cardiovascular ...Orally, hypotension has been reported rarely in a clinical trial (104650).
Dermatologic ...Orally, skin rash and itching have been reported after use of alpha-lipoic acid (16391,20490,21674,96233,104650). Topically, alpha-lipoic acid can cause local irritation, including burning, stinging, mild rash, or contact dermatitis (12021,30836,111701). In one case, an 86-year-old female developed allergic contact dermatitis with severe itching and oozing after applying alpha-lipoic acid 5% cream to her lower extremities. The patient had a positive skin patch test for alpha-lipoic acid, confirming the causative agent (111701). In another case, a 47-year-old female developed contact dermatitis characterized by a pruritic rash and labial adhesions hours after applying a 5% vulvar serum containing lipoic acid 0.9 grams, vitamin E, vitamin C, hyaluronic acid, and retinol palmitate to the vulva to treat vulvar lichen sclerosis. Testing confirmed that the causative agent was alpha-lipoic acid (111704). Intravenously, local allergic reactions have occurred at the injection site (1547).
Endocrine ...Orally, at least 50 published cases of insulin autoimmune syndrome (IAS) thought to be associated with use of alpha-lipoic acid have been reported (16392,104656,104657,104658,104659,107893,112941). Most reported cases have been associated with alpha-lipoic acid supplements or enriched foods; IAS has not been reported with intake of alpha-lipoic acid in food. IAS has been linked to compounds, such as alpha-lipoic acid, that contain sulfhydryl groups, but it is unclear if taking alpha-lipoic acid with other drugs known to trigger IAS increases the risk (107893,112941). IAS is characterized by very high serum insulin levels and high titers of autoantibodies against endogenous insulin. Sulfhydryl groups interact with disulfide bonds of insulin, increasing its immunogenicity (112941). Symptoms include severe spontaneous hypoglycemic episodes, as well as hunger and neuroglycopenic symptoms such as blurred vision, weakness, confusion, dizziness, sweating, and palpitations (104656,104657,107893,112941). Time to onset of IAS ranges from 1 week to 4 months (107893). Most cases of IAS have been reported in Japan and have occurred in individuals with the human leucocyte antigen (HLA)-DRB1*04:06 allele (16392,104656,107893). For patients of European decent, cases of IAS have mainly occurred in individuals with the HLA-DRB1*04:03 allele (104656,104658,104659,107893). This suggests that either of these alleles might produce a genetic predisposition to alpha-lipoic acid-associated IAS. Reported doses of alpha-lipoic acid have ranged from 200-800 mg daily, most commonly 600 mg daily (104656,104658,104659,107893). IAS-related hypoglycemic episodes have been treated with oral or intravenous glucose or sucrose, as well as prednisone. Episodes decline following discontinuation of alpha-lipoic acid, and insulin values normalize within 3-9 months (104656,104658,104659,107893).
Gastrointestinal ...Orally, heartburn, nausea, and vomiting have been reported after use of alpha-lipoic acid (3557,12106,16391,20475,30844,96225,101868,103327,103328,103333)(103335,104650,104654,104655). Higher doses (1200-1800 mg daily) seem to cause more severe effects than lower doses (600 mg daily) (3557,20475,30844,96225). Alpha-lipoic acid may also cause a burning sensation from the throat to the stomach, abdominal discomfort, or bitter taste when used orally (20478,20490,21664,96225). Intravenously, alpha-lipoic acid can cause gastrointestinal upset, including nausea and vomiting. Adverse effects are more common in patients receiving higher intravenous doses (3557) and may be more common in the elderly (96225).
Genitourinary ...Orally, alpha-lipoic acid may cause urinary disorders (20479). Oral alpha-lipoic acid has also been associated with a change in urine odor (96225,103327).
Neurologic/CNS
...Orally, alpha-lipoic acid may cause headache (21664,103328,104655) or dizziness (104650).
Intravenously, paresthesias have been reported to worsen temporarily at the beginning of therapy. Also, intravenous alpha-lipoic acid can cause headache. Adverse effects are more common in patients receiving higher intravenous doses (3557).
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
...Orally and topically, cocoa is generally well tolerated.
Most Common Adverse Effects:
Orally: Borborygmi, constipation, diuresis, gastrointestinal discomfort, headaches, and nausea.
Serious Adverse Effects (Rare):
Orally: Tachycardia.
Cardiovascular ...Some cases of increased heart rate have been reported with oral cocoa use (13161,42132).
Dermatologic ...In some cases, when taken orally, cocoa can cause allergic skin reactions (13161). Topically, cocoa butter has occasionally caused a rash. In animals, it has been shown to block pores and cause acne; however, this has not been found in humans (11).
Gastrointestinal ...In human trials, chocolate consumption was associated with a higher incidence of flatulence, irritable bowel syndrome, upset stomach, gastric upset, borborygmi (a gurgling noise made by fluid or gas in the intestines), bloating, nausea, vomiting, and constipation or obstipation (41986,42221,41921,1374,42220,1373,42099,42097,42156,42123,18229,42169,42111). Chocolate consumption has been implicated as a provoking factor in gastroesophageal reflux disease (GERD) (41974,42005,41946,1374). Unpalatability has been reported (42079,42169). Consumption of chocolate and other sweet foods may lead to increased dental caries (42129,42030).
Genitourinary ...In some cases, when taken orally, cocoa can cause increased urination (13161).
Neurologic/CNS ...In some cases, when taken orally, cocoa can cause shakiness and might trigger migraine and other headaches (13161,42169,92271).
Other ...Due to the high sugar and caloric content of chocolate, there is concern about weight gain in people who consume large amounts of chocolate (17187).
General
...Orally, diindolylmethane is generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, gas, headache, nausea, rash, and vomiting.
Serious Adverse Effects (Rare):
Orally: Drug rash with eosinophilia and systemic symptoms (DRESS).
Dermatologic ...Orally, diindolylmethane can cause rash (47615,93836). In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS) after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. An allergen patch test was positive for diindolylmethane (93840).
Endocrine ...Orally, diindolylmethane was associated with grade 3 asymptomatic hyponatremia in 2 of 4 patients taking 600 mg daily for 28 days in one clinical study. Hyponatremia was not seen in the 8 patients taking diindolylmethane 150-450 mg daily (47729).
Gastrointestinal ...Orally, diindolylmethane can cause nausea, vomiting, diarrhea, and gas (47652,47676,47709,47729,93836).
Genitourinary ...Orally, diindolylmethane can cause the urine to darken (93836).
Hematologic ...In one case report, a 65-year-old male developed a deep vein thromboembolism (DVT) and bilateral pulmonary emboli (PE) within a few weeks of initiating treatment with diindolylmethane. It is unclear if diindolylmethane contributed to this event; the patient was at increased risk for emboli due to his age, weight, tobacco use, and possible history of pulmonary embolism (93835).
Hepatic ...In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS), involving elevated liver transaminases, after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. An allergen patch test was positive for diindolylmethane (93840).
Immunologic ...In one case report, a patient developed drug rash with eosinophilia and systemic symptoms (DRESS) after consuming a product containing diindolylmethane, vitamin E, and broccoli powder. The patient developed fever, activated lymphocytes, and swollen lymph nodes. An allergen patch test was positive for diindolylmethane (93840).
Musculoskeletal ...Orally, diindolylmethane has been reported to cause arthralgias (47615).
Neurologic/CNS ...Orally, diindolylmethane can cause headache (47652,47676,93836). One case has reported ischemic stroke in a 38-year-old female with a history of a patent foramen ovale (PFO), traumatic subdural hematoma, right partial hemicraniectomy, and use of several supplements, including 200 mg of diindolylmethane daily, vitamin D3, vitamin K2, elderberry, caffeine, and possibly cannabis (112895). It is unclear if diindolylmethane contributed to this event; the patient was at increased risk for stroke due to PFO and other factors.
General ...There is currently a limited amount of information available about the adverse effects of laxogenin. Products labeled as containing laxogenin or 5-alpha-hydroxy laxogenin might contain contaminants, including prohibited compounds (99191).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
...In foods, resveratrol is well tolerated.
