Below is general information about the interactions of the known ingredients contained in the product Super Detox. 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, artichoke leaf extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
 Details
A meta-analysis of small clinical studies shows that taking artichoke leaf extract for 8-12 weeks can modestly reduce fasting plasma glucose when compared with placebo (105768).
|
Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
Details
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo (105767).
|
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2B6.
Details
In vitro research shows that artichoke leaf extract inhibits CYP2B6 activity (97717). However, this interaction has not been reported in humans.
|
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2C19.
Details
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity (97717). However, this interaction has not been reported in humans.
|
Theoretically, bupleurum might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, bupleurum might decrease the effects of antidiabetes drugs.
Details
|
Theoretically, bupleurum might decrease the effects of immunosuppressants.
Details
|
Theoretically, concomitant use with alcohol might decrease calcium D-glucarate activity.
Details
There is some evidence that urinary excretion of calcium D-glucarate metabolites increases in people consuming alcohol (779).
|
Theoretically, calcium D-glucarate might increase the clearance of drugs that undergo glucuronidation.
Details
|
Theoretically, calcium D-glucarate may reduce plasma levels of kanamycin.
Details
Calcium D-glucarate may increase the rate of kanamycin elimination, which may decrease its clinical and adverse effects (777).
|
Taking milk thistle with antidiabetes drugs may increase the risk of hypoglycemia.
Details
|
Theoretically, milk thistle might inhibit CYP2B6.
Details
An in vitro study shows that silybin, a constituent of milk thistle, binds to and noncompetitively inhibits CYP2B6. Additionally, silybin might downregulate the expression of CYP2B6 by decreasing mRNA and protein levels (112229).
|
It is unclear if milk thistle inhibits CYP2C9; research is conflicting.
Details
In vitro research suggests that milk thistle might inhibit CYP2C9 (7089,17973,17976). However, contradictory clinical research shows that milk thistle extract does not inhibit CYP2C9 or significantly affect levels of the CYP2C9 substrate tolbutamide (13712,95026). Differences in results could be due to differences in dosages or formulations utilized (95026).
|
It is unclear if milk thistle inhibits CYP3A4; research is conflicting.
Details
|
Theoretically, milk thistle might interfere with estrogen therapy through competition for estrogen receptors.
Details
|
Theoretically, milk thistle might affect the clearance of drugs that undergo glucuronidation.
Details
Laboratory research shows that milk thistle constituents inhibit uridine diphosphoglucuronosyl transferase (UGT), the major phase 2 enzyme that is responsible for glucuronidation (7318,17973). Theoretically, this could decrease the clearance and increase levels of glucuronidated drugs. Other laboratory research suggests that a milk thistle extract of silymarin might inhibit beta-glucuronidase (7354), although the significance of this effect is unclear.
|
Theoretically, milk thistle might interfere with statin therapy by decreasing the activity of organic anion transporting polypeptide 1B1 (OATB1B1) and inhibiting breast cancer resistance protein (BCRP).
Details
Preliminary evidence suggests that a milk thistle extract of silymarin can decrease the activity of the OATP1B1, which transports HMG-CoA reductase inhibitors into the liver to their site of action. The silibinin component also inhibits BCRP, which transports statins from the liver into the bile for excretion. However, in a preliminary study in healthy males, silymarin 140 mg three times daily had no effect on the pharmacokinetics of a single 10 mg dose of rosuvastatin (16408).
|
Theoretically, milk thistle may induce cytochrome P450 3A4 (CYP3A4) enzymes and increase the metabolism of indinavir; however, results are conflicting.
Details
One pharmacokinetic study shows that taking milk thistle (Standardized Milk Thistle, General Nutrition Corp.) 175 mg three times daily in combination with multiple doses of indinavir 800 mg every 8 hours decreases the mean trough levels of indinavir by 25% (8234). However, results from the same pharmacokinetic study show that milk thistle does not affect the overall exposure to indinavir (8234). Furthermore, two other pharmacokinetic studies show that taking specific milk thistle extract (Legalon, Rottapharm Madaus; Thisilyn, Nature's Way) 160-450 mg every 8 hours in combination with multiple doses of indinavir 800 mg every 8 hours does not reduce levels of indinavir (93578).
|
Theoretically, milk thistle might increase the levels and clinical effects of ledipasvir.
Details
Animal research in rats shows that milk thistle increases the area under the curve (AUC) for ledipasvir and slows its elimination (109505).
|
Theoretically, concomitant use of milk thistle with morphine might affect serum levels of morphine and either increase or decrease its effects.
Details
Animal research shows that milk thistle reduces serum levels of morphine by up to 66% (101161). In contrast, laboratory research shows that milk thistle constituents inhibit uridine diphosphoglucuronosyl transferase (UGT), the major phase 2 enzyme that is responsible for glucuronidation (7318,17973). Theoretically, this could decrease the clearance and increase morphine levels. The effect of taking milk thistle on morphine metabolism in humans is not known.
|
Theoretically, milk thistle might increase the absorption of P-glycoprotein substrates. However, this effect does not seem to be clinically significant.
Details
Although in vitro research shows that milk thistle can inhibit P-glycoprotein activity (95019), clinical research does not agree. A small pharmacokinetic study in healthy volunteers shows that taking milk thistle (Enzymatic Therapy Inc.) 900 mg, standardized to 80% silymarin, in 3 divided doses daily for 14 days does not affect absorption of digoxin, a P-glycoprotein probe substrate (35825).
|
Theoretically, milk thistle might decrease the clearance and increase levels of raloxifene.
Details
Laboratory research suggests that the milk thistle constituents silibinin and silymarin inhibit the glucuronidation of raloxifene in the intestines (93024).
|
Milk thistle might decrease the clearance of sirolimus.
Details
Pharmacokinetic research shows that a milk thistle extract of silymarin decreases the apparent clearance of sirolimus in hepatically impaired renal transplant patients (19876). It is unclear if this interaction occurs in patients without hepatic impairment.
|
Theoretically, milk thistle might decrease the levels and clinical effects of sofosbuvir.
Details
Animal research in rats shows that milk thistle reduces the metabolism of sofosbuvir, as well as the hepatic uptake of its active metabolite (109505).
|
Theoretically, the milk thistle constituent silibinin might increase tamoxifen levels and interfere with its conversion to an active metabolite.
Details
Animal research suggests that the milk thistle constituent silibinin might increase plasma levels of tamoxifen and alter its conversion to an active metabolite. The mechanism appears to involve inhibition of pre-systemic metabolism of tamoxifen by cytochrome P450 (CYP) 2C9 and CYP3A4, and inhibition of P-glycoprotein-mediated efflux of tamoxifen into the intestine for excretion (17101). Whether this interaction occurs in humans is not known.
|
Theoretically, milk thistle might increase the effects of warfarin.
Details
In one case report, a man stabilized on warfarin experienced an increase in INR from 2.64 to 4.12 after taking a combination product containing milk thistle 200 mg daily, as well as dandelion, wild yam, niacinamide, and vitamin B12. Levels returned to normal after stopping the supplement (101159). Although a direct correlation between milk thistle and the change in INR cannot be confirmed, some in vitro research suggests that milk thistle might inhibit cytochrome P450 2C9 (CYP2C9), an enzyme involved in the metabolism of various drugs, including warfarin (7089,17973,17976).
|
N-acetyl cysteine might reduce the effects of activated charcoal, while activated charcoal might reduce the absorption of N-acetyl cysteine.
Details
N-acetyl cysteine appears to reduce the capacity of activated charcoal to adsorb acetaminophen and salicylic acid (7869). Conversely, although clinical research suggests that although activated charcoal can reduce the absorption of N-acetyl cysteine by up to 40%, it does not seem to reduce its clinical effects (1755,22774,22775,64501,64647). Other clinical evidence suggests that activated charcoal does not affect the absorption of N-acetyl cysteine (22776,22777).
|
Theoretically, N-acetyl cysteine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
Clinical research suggests that intravenous N-acetyl cysteine decreases prothrombin time, prolongs coagulation time, decreases platelet aggregation, and increases blood loss in surgical patients (64511,64644). Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin (22780,64780).
|
Theoretically, N-acetyl cysteine might increase the risk of hypotension when taken with antihypertensive drugs.
Details
Animal research suggests that N-acetyl cysteine potentiates the hypotensive effects of the angiotensin-converting enzyme inhibitors (ACEIs) captopril and enalaprilat (22785). Theoretically, combining N-acetyl cysteine with other antihypertensive drugs might increase the risk of hypotension.
|
Theoretically, N-acetyl cysteine might interfere with the antimalarial effects of chloroquine.
Details
Animal research suggests that N-acetyl cysteine might reduce the antimalarial effects of chloroquine by increasing cellular levels of glutathione (22786).
|
N-acetyl cysteine can increase the risk for hypotension and headaches when taken with intravenous or transdermal nitroglycerin.
Details
Clinical research shows that concomitant administration of N-acetyl cysteine and intravenous or transdermal nitroglycerin can cause severe hypotension (2246) and intolerable headaches (2245,2280). Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin (22780,64780).
|
Although some laboratory research suggests that red clover may have anticoagulant and antiplatelet activity, clinical research has not shown this effect.
Details
In vitro research suggests that genistein in red clover has antiplatelet effects, and historically, red clover was thought to have anticoagulant effects due to its coumarin content. However, some experts state that this is unlikely as most natural coumarins have not been shown to have anticoagulant effects, and their content in red clover is low (17091,19557,19558,19559). Additionally, some clinical research in postmenopausal patients found no effect on coagulation or prothrombin time with the use of red clover flowering tops 378 mg daily for 12 months or red clover isoflavone (Rimostil) 50 mg daily for 2 years (17091,91524).
|
Theoretically, soy might reduce the clearance of caffeine; however, a small clinical study found no effect.
Details
Red clover contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females (23582). However, this effect does not seem to occur with the lower amounts of genistein found in red clover. A clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP1A2; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover inhibits CYP1A2 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine, a CYP1A2 probe substrate (105693).
|
Theoretically, red clover might increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
In vitro evidence suggests that red clover weakly inhibits CYP2C19 (12479). This interaction has not been reported in humans.
|
Theoretically, red clover might increase levels of drugs metabolized by CYP2C9; however, a small clinical study found no effect.
Details
In vitro evidence suggests that red clover might inhibit CYP2C9 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of tolbutamide, a CYP2C9 probe substrate (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP3A4; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover might inhibit CYP3A4 isoenzymes (6450,12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of alprazolam, a CYP3A4 probe substrate (105693).
|
Theoretically, concomitant use of large amounts of red clover might interfere with estrogen therapy.
Details
|
Theoretically, red clover might increase the risk of methotrexate toxicity.
Details
In a case report, a 52-year-old female receiving weekly methotrexate injections for psoriasis developed symptoms of methotrexate toxicity, including severe vomiting and epigastric pain, after three days of taking red clover 430 mg daily. Toxicity resolved after red clover was discontinued. However, no liver function tests or methotrexate levels were reported (91522).
|
Theoretically, the phytoestrogens in red clover might interfere with tamoxifen.
Details
In vitro and animal research suggests that genistein, a constituent of red clover, might antagonize the antitumor effects of tamoxifen (8192). However, there is some evidence from an animal study that red clover does not reduce the efficacy of tamoxifen (102901). Until more is known, tell patients taking tamoxifen to avoid red clover.
|
Theoretically, sulforaphane might alter the levels and clinical effects of CYP1A2 substrates.
Details
Animal and in vitro research shows that sulforaphane inhibits CYP1A2 enzyme activity. However, its precursor glucoraphanin also appears to increase the expression of the CYP1A2 enzyme, which could lead to increased metabolism of CYP1A2 substrates (12701,105083,105085). These effects have not been reported in humans.
|
Theoretically, sulforaphane might increase the levels and effects of CYP2E1 substrates.
Details
In vitro evidence shows that sulforaphane inhibits CYP2E1 enzymes (105083). This interaction has not been reported in humans.
|
Theoretically, sulforaphane might increase the levels and effects of CYP3A4 substrates.

Below is general information about the adverse effects of the known ingredients contained in the product Super Detox. 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, artichoke extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, flatulence, hunger, and nausea.
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis to artichoke inulin has been reported in individuals sensitive to inulin.
Topically: Chest tightness, cough, and dyspnea after occupational exposure in sensitive individuals.
Dermatologic
...Artichoke can cause an allergic reaction in some patients.
Patients sensitive to the Asteraceae/Compositae family may be at the greatest risk. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. Topically, allergic contact dermatitis can occur with the use of artichoke. This has been attributed to the constituent cynaropicrin (11,52206,52226,52230). Redness in the face (11774) and sweating (91475) have been reported rarely following oral use of artichoke extract.
Occupational or airborne exposure to artichoke may also cause allergic reactions. In one case, a 52-year-old male presented with severe spongiotic dermatitis in exposed areas that was recurrent over the past 8 years. A patch test confirmed allergies to artichokes and sesquiterpene lactones, a group of allergens from the Compositae family, and the patient confirmed occupational and airborne exposure to artichokes during the time of his symptoms. The patient improved considerably after treatment with dupilumab (111565).
Gastrointestinal
...Orally, artichoke extract might increase abdominal discomfort, flatulence, diarrhea, hunger, and nausea in some patients (2562,52238,91475).
Abdominal pain and a bitter taste in the mouth were reported by a single person following oral use of a dietary supplement containing artichoke extract, as well as red yeast rice, pine bark extract, and garlic extract (89452). It is not clear if this adverse effect was due to artichoke, other ingredients, or the combination.
In one case report, the autopsy of an 84-year-old female revealed a colonic bezoar comprised of artichoke fiber and fragments. This bezoar caused complete intestinal obstruction, leading to fatal acute peritonitis. Although rare, patients who lack adequate teeth and/or who have a history of gastric surgery are at increased risk for fibrous bezoar formation (97716).
Pulmonary/Respiratory
...Following occupational exposure, allergic symptoms including dyspnea, cough, chest tightness, and asthma symptoms or exacerbation have been reported.
The effects were attributed to sensitization to artichoke. Subsequent nasal challenge with artichoke extract caused reduced nasal patency in these patients (52210,52230).
Orally, severe anaphylactic shock in response to artichoke inulin as an ingredient in commercially available products has been reported (52217). Individuals with a noted sensitivity to artichokes should consume inulin with caution. While rare, individuals with a known inulin allergy should avoid artichoke and artichoke extract.
General ...Orally, bupleurum seems to be well tolerated. However, most research has evaluated bupleurum in combination with other ingredients; the adverse effects of bupleurum when used alone are unclear.
Gastrointestinal ...Orally, a specific bupleurum-containing combination product (sho-saiko-to) has been reported to cause nausea, anorexia, and abdominal fullness (37391). It is unclear if these adverse effects are due to bupleurum, other ingredients, or the combination.
Hepatic ...Orally, a specific bupleurum-containing combination product (sho-saiko-to) has been associated with at least 24 reported cases of hepatotoxicity (92575). It is unclear if these adverse effects are due to bupleurum, other ingredients, or the combination.
Neurologic/CNS ...Orally, a specific bupleurum-containing combination product (sho-saiko-to) has been reported to cause fatigue and paresthesia (37391). It is unclear if these adverse effects are due to bupleurum, other ingredients, or the combination.
Pulmonary/Respiratory ...Orally, combination products containing bupleurum have been reported to cause eosinophilic pneumonia (354), pulmonary edema (361), and multiple cases of pneumonitis (355,356,357,37404). A specific combination product (sho-saiko-to), used in combination with interferon-alpha in patients with chronic active hepatitis, has also been associated with multiple cases of pneumonitis (358,359,360). It is unclear if these adverse effects are due to bupleurum, other ingredients, or the combination.
General ...No adverse effects have been reported; however, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally, milk thistle is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal bloating, diarrhea, dyspepsia, flatulence, and nausea. However, these adverse effects do not typically occur at a greater frequency than with placebo.
Serious Adverse Effects (Rare):
Orally: Allergic reactions, including anaphylaxis, have been reported.
Dermatologic ...Orally, milk thistle may cause allergic reactions including urticaria, eczema, skin rash, and anaphylaxis in some people (6879,7355,8956,63210,63212,63238,63251,63315,63325,95029). Allergic reactions may be more likely to occur in patients sensitive to the Asteraceae/Compositae family (6879,8956). A case report describes a 49-year-old female who developed clinical, serologic, and immunopathologic features of bullous pemphigoid after taking milk thistle orally for 6 weeks. Symptoms resolved after treatment with prednisone and methotrexate (107376). Topically, milk thistle can cause erythema (110489).
Gastrointestinal ...Mild gastrointestinal symptoms have been reported, including nausea, vomiting, bloating, diarrhea, epigastric pain, abdominal colic or discomfort, dyspepsia, dysgeusia, flatulence, constipation, and loss of appetite (2616,6879,8956,13170,63140,63146,63160,63210,63218,63219)(63221,63244,63247,63250,63251,63320,63321,63323,63324,63325)(63327,63328,95024,95029,107374). There is one report of a 57-year-old female with sweating, nausea, colicky abdominal pain, diarrhea, vomiting, weakness, and collapse after ingesting milk thistle; symptoms subsided after 24-48 hours without medical treatment and recurred with re-challenge (63329).
Musculoskeletal ...In one clinical study three patients taking milk thistle 200 mg orally three times daily experienced tremor; the incidence of this adverse effect was similar for patients treated with fluoxetine 10 mg three times daily (63219).
General
...Orally, intravenously, and as an inhalation, N-acetyl cysteine is generally well-tolerated when used in typical doses.
Most adverse effects to N-acetyl cysteine occur when single doses of greater than 9 grams are used or when a regimen of greater than 30 grams daily is followed.
Most Common Adverse Effects:
Orally: Diarrhea, dry mouth, dyspepsia, heartburn, loss of appetite, nausea, and vomiting.
Intravenously: Skin rash and hypersensitivity reactions.
Inhaled: Bronchospasm, cough, epigastric pain, throat irritation, and wheezing.
Serious Adverse Effects (Rare):
Orally: Chest tightness, hemoptysis, and palpitations have been reported.
Intravenously: Anaphylaxis, angina, dystonic reactions, tachycardia, and transient sinus bradycardia have been reported.
Cardiovascular
...Intravenously, N-acetyl cysteine has been reported to significantly increase systolic and diastolic blood pressure after exposure to nitroglycerin when compared with placebo (2280).
Tachycardia, chest pain, angina, and transient sinus bradycardia have been rarely reported after administration of intravenous N-acetyl cysteine (2280,7872,64658).
Intratracheally, infants receiving 5% N-acetyl cysteine every four hours for chronic lung disease have developed bradycardia (64490).
Orally, palpitations and chest tightness have been reported rarely in clinical research evaluating oral N-acetyl cysteine at doses up to 600 mg twice daily (64675,64717,64762).
Dermatologic
...Orally, N-acetyl cysteine may cause hives (64713,64739,64813), flushing (2260,64715), and edema (64714).
Rash has also been reported (64510,64715,64717,102656). In one study, flushing was reported in 2% of patients receiving 600 mg of N-acetyl cysteine orally twice daily for six months (2260).
Intravenously, N-acetyl cysteine may cause rash, and the occurrence seems to be more common than with oral use (2254,64492,64562,64658,64759,64794). Hives (2280,64794), facial edema (2280), flushing (64412), and pruritus (64658,64763) have also been reported. In a small case series of 10 healthy male patients receiving 150 mg/kg of intravenous N-acetyl cysteine for muscle fatigue, erythema was experienced 30 minutes after infusion. Other side effects reported by these patients include facial erythema, palmar erythema, and sweating (64763). In other clinical research, three patients developed an erythematous flare at the sites of previous venipunctures after receiving 5.5 gm/m2 of N-acetyl cysteine with doxorubicin therapy (64712). Pain, inflammation, and excoriation of the skin have been reported after a 20% N-acetyl cysteine solution leaked from the catheter in one patient (64726).
Gastrointestinal
...Orally, gastrointestinal complaints are the most common adverse effects reported with N-acetyl cysteine.
These include heartburn (64608,64715,64717,64738,64739,102666), dyspepsia (1710,64715,64717,64724,64738), and epigastric pain (2260,10429,64715,64717). In one case report, esophagitis related to ulcerations occurred following intake of N-acetyl cysteine while in the supine position with inadequate water (102655). Other common side effects include loss of appetite (64715,64812), flatulence (2256,64510), diarrhea (64713,64715,97049), constipation (64715), dry mouth (64715,64724), nausea (7868,11430,64715,64724,64738,64812,97049), vomiting (64717,64724,64715,97049), gastric upset (64510,64545,97045,97049), acid reflux (108450), changes in bowel habits (108450), and intolerance to taste and odor (64510,64545). N-acetyl cysteine's unpleasant odor makes it difficult for some patients to take orally. Using a straw to drink N-acetyl cysteine solutions can improve tolerability. Additionally, placement of a nasogastric or duodenal tube and administration of metoclopramide or ondansetron can be helpful for patients unable to tolerate oral N-acetyl cysteine (17).
Intravenously, N-acetyl cysteine may cause diarrhea (64712), dyspepsia, nausea, vomiting (64763), mild gastrointestinal upset (102657), and metallic taste (64763).
When inhaled, N-acetyl cysteine may cause epigastric pain and throat irritation (64703,64707,64674).
Genitourinary ...Orally, dysuria was reported in 2% of patients receiving 600 mg of N-acetyl cysteine twice daily for 6 months in one clinical trial (2260).
Hematologic
...In general, hematologic adverse reactions are reported more frequently with intravenous N-acetyl cysteine compared with oral use.
In surgical patients, decreased prothrombin time (1341,64511), prolonged coagulation time (64511), increased blood loss (64511,64644), and decreased platelet aggregation (64511) have been reported after administration of IV N-acetyl cysteine. In one clinical trial, six healthy patients were administered a loading dose of IV N-acetyl cysteine 10 mg/kg followed by 10 mg/kg per hour for 32 hours. All patients experienced a decrease in prothrombin time by 30% to 40%. The decrease prothrombin time (25.4 sec to 20.6 sec) reached a steady state after 16 hours (1341). In a clinical trial evaluating patients with acute myocardial infarction, hemorrhage occurred in three patients taking intravenous N-acetyl cysteine 10 mg/min, heparin (per study protocol), and aspirin (7872). Two pediatric patients receiving intravenous N-acetyl cysteine (loading dose: 140 mg/kg followed by 70 mg/kg) experienced episodes of coagulopathy; however, patients were being treated for acetaminophen overdose (64794).
Hemoptysis was reported in six patients receiving 200 mg of N-acetyl cysteine orally twice daily for 6 months for treatment of chronic bronchitis (64739).
Immunologic
...Orally, anaphylaxis to N-acetyl cysteine has been rarely reported (64794).
However, anaphylactic reactions to intravenous N-acetyl cysteine appear to be more common (1716,64412,64449,64628,64710,64711,64721,64786,64789).
Anaphylactic reactions to N-acetyl cysteine have involved rash, angioedema, hypotension, and bronchospasm (64449,64711,64720). The mechanism of this reaction is unclear, but some data suggest it is not an immunologic hypersensitivity reaction but rather an acute toxic effect of N-acetyl cysteine (64786,64641,64720). Management guidelines for the treatment of anaphylactoid reactions to intravenous N-acetyl cysteine have been published. In most cases, treatment is not required or treatment with diphenhydramine or salbutamol is sufficient to continue or restart N-acetyl cysteine infusion. Antihistamines are useful in controlling and preventing recurrence of anaphylactoid symptoms (1716).
Musculoskeletal ...In one clinical trial, joint pain was reported in more than 15% of patients receiving oral N-acetyl cysteine (64608). In other research, one patient experienced pain in the legs while taking 600 mg of N-acetyl cysteine twice daily for the treatment of chronic bronchitis (64762).
Neurologic/CNS
...Orally, headache has been frequently reported with N-acetyl cysteine in clinical research (7873,11430,64510,64608,64672,64713,64715,64724,64762).
Other less common adverse effects reported in patients taking oral N-acetyl cysteine at a total daily dose of 600-1200 mg include dizziness (64715,64717,64724,64762), tiredness (64675,64717), vivid dreams (102666), disorientation, and inability to concentrate (64673). One pediatric patient receiving oral N-acetyl cysteine (loading dose: 140 mg/kg followed by 70 mg/kg) experienced encephalopathy (64794).
Intravenously, N-acetyl cysteine has been associated with rare neurologic adverse reactions , including headache (7872), lightheadedness (64763), and dystonic reactions (64794). In a previously healthy 2-year-old female, status epilepticus occurred during intravenous N-acetyl cysteine therapy for paracetamol ingestion (64781). Increased deterioration in bulbar function in patients with amyotrophic lateral sclerosis has also been reported with IV N-acetyl cysteine (2254).
Ocular/Otic ...While rare, blurred vision has been reported in research on oral N-acetyl cysteine (64715). Additionally, in a previously healthy 2-year-old female, status epilepticus followed by cortical blindness occurred during intravenous N-acetyl cysteine therapy for paracetamol ingestion. In this case, vision was almost completely recovered 18-months later (64781).
Psychiatric ...Intravenously, dysphoria was experienced 30 minutes after infusion of N-acetyl cysteine in 8 of 10 healthy males assessed in one clinical study (64763).
Pulmonary/Respiratory
...Respiratory adverse reactions to N-acetyl cysteine are most commonly reported with inhalable dosage forms.
These include wheezing (64455,64707), bronchospasm (64455,64699), and cough (64455,64456,64703,64811). While less frequent, wheezing (64675), bronchospasm (64675), increased sputum production (7868), cough (7868,64510), decreased peak flow (64510), dyspnea (64714), and cold symptoms (64510) have been reported with oral N-acetyl cysteine in clinical research. A few cases of wheezing (64718,64719), cough (64763), and bronchospasm (64658) have also been reported with intravenous N-acetyl cysteine. Additionally, respiratory arrest has been reported in one case where a 16 year-old female was being treated for acetaminophen toxicity with intravenous N-acetyl cysteine (64450).
Two premature infants receiving 5% N-acetyl cysteine via intratracheal instillation for the treatment of chronic lung disease had an increased frequency of cyanotic spells (64490).
Other ...Injection site reactions, including burning and phlebitis, have been reported in patients receiving IV N-acetyl cysteine (1341,64763). Fever associated with IV N-acetyl cysteine was reported in one patient during clinical research (64759).
General
...Orally and topically, red clover seems to be well tolerated.
Most Common Adverse Effects:
Orally: Myalgia, nausea, and vaginal spotting.
Dermatologic ...Orally, a specific red clover isoflavone product (Promensil) has been associated with mild cases of psoriasis and thrush, although a direct causal link has not been established (9552).
Gastrointestinal ...Orally, red clover has been reported to cause nausea (8194).
Genitourinary ...In human research, 80 mg, but not 40 mg, of a specific red clover isoflavone product (Promensil) increased the duration of menstrual cycles in patients with mastalgia (9552). Red clover has also been reported to cause vaginal spotting (8194).
Hematologic ...In one case report, a 53-year-old female had a spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero. It is not clear if this was due to red clover, another ingredient, the combination of ingredients, or other factors (70419). In another case report, a 55-year-old female with protein S deficiency and systemic lupus erythematosus (SLE) had temporary vision loss in the left eye from hemiretinal vein thrombosis 3 days after taking a combination phytoestrogen product containing red clover 250 mg, wild yam 276 mg, dong quai 100 mg, and black cohosh 250 mg (13155). It is unclear if red clover contributed to this event.
Musculoskeletal ...Orally, red clover has been reported to cause myalgia (8194).
Neurologic/CNS ...Orally, a specific red clover isoflavone product (Medoflavon) has been associated with headache, although with a similar frequency to placebo (19545).
Oncologic ...Due to potential estrogenic effects of red clover isoflavones, there has been some concern that red clover might increase the risk of estrogen-sensitive cancers such as breast cancer or uterine cancer. A meta-analysis of 8 clinical trials suggests that increased intake of red clover- and soy-derived isoflavones may modestly increase mammographic breast density in premenopausal, but not postmenopausal, adults when compared with placebo. However, in a sub-group analysis assessing only isolated red clover isoflavones, there was no change in breast density (70428). Furthermore, a 2015 review by the European Food Safety Authority (EFSA) reported no increase in risk of breast cancer in females taking isoflavone-containing supplements (91725). Similarly, no effect was found on endometrial thickness and histopathological changes in the uterus after up to 36 months of supplementation with 40-120 mg daily of isoflavones from red clover extract (91725).
General
...Orally, sulforaphane seems to be well tolerated.
Most Common Adverse Effects:
Orally: Bowel discomfort, heartburn, stomach upset, and vomiting.
Gastrointestinal ...Orally, sulforaphane and sulforaphane-rich extracts can cause bowel discomfort, stomach upset, heartburn, and vomiting (95251,95252,95260,95265,95267,95268,98501,104537,108132). A specific stabilized form of sulforaphane (Cavamax W6) caused mild stomach upset in 60% of subjects in a small study (95252). However, in some clinical studies, the gastrointestinal side effects reported with sulforaphane did not occur more frequently than with placebo (95268).
Hepatic ...Orally, sulforaphane has been associated with one case of elevated liver enzyme levels. However, the patient ran a marathon the day before testing, and levels returned to normal within one week (95262).
Neurologic/CNS ...Orally, sulforaphane has been reported to cause headache in one clinical study (104537). In another clinical trial, insomnia and irritability were reported (108131). Sulforaphane has also been associated with two cases of seizure in males with autism. In one case, a patient with a recent history of seizure experienced a seizure after taking sulforaphane for 3 weeks. In another case, a patient with seizures which had been well-controlled with antiepileptic drugs for more than 1 year experienced a seizure 3 weeks after discontinuing sulforaphane. It is unclear if sulforaphane precipitated seizures in these patients (95267).
Other ...Orally, sulforaphane has been reported to cause increased weight gain. In one clinical study in males 13-27 years of age with autism, patients taking sulforaphane gained an additional 4 pounds on average over 18 weeks when compared with those taking placebo (95267).
