INSUFFICIENT RELIABLE EVIDENCE to RATE
Below is general information about the safety of the known ingredients contained in the product Berberine 1200 mg. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. Berberine has been used safely in doses up to 1.5 grams daily for 6 months (262,13520,20579) (34317,34228,34247,34253,34262,34263,34265,34267,34277,34282), (34283,34286,34287,34289,34293,34301,34305,34306,34319,34325)(99920,99921,103194) or up to 1 gram daily for 24 months (99921,103197). ...when used topically. Berberine ointment has been applied with apparent safety for up to 20 days (13526).
CHILDREN: LIKELY UNSAFE
when used orally in newborns.
Berberine can cause kernicterus, particularly in preterm neonates with hyperbilirubinemia (2589). It is unclear if berberine is safe in older children.
PREGNANCY: LIKELY UNSAFE
when used orally.
Berberine is thought to cross the placenta and may cause harm to the fetus. Kernicterus has developed in newborn infants exposed to berberine (2589). Also, berberine may stimulate uterine contractions (91951).
LACTATION: LIKELY UNSAFE
when used orally.
Berberine can be transferred to the infant through breast milk (2589).
Below is general information about the interactions of the known ingredients contained in the product Berberine 1200 mg. 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, berberine might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, berberine may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, berberine might have additive effects with antihypertensive drugs.
Details
|
Theoretically, berberine might increase the sedative effects of CNS depressants.
Details
|
Berberine can increase serum levels of cyclosporine.
Details
|
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2C9.
Details
Preliminary clinical research shows that berberine can inhibit CYP2C9 (34279). Theoretically, taking berberine with drugs metabolized by CYP2C9 might increase drug levels and increase the risk of adverse effects.
|
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, berberine might increase serum levels of drugs metabolized by CYP3A4.
Details
|
Theoretically, berberine may increase serum levels of dextromethorphan.
Details
Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan (34279). This may increase the effects and side effects of dextromethorphan.
|
Berberine might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Details
Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan (34279).
|
Theoretically, berberine might increase the therapeutic and adverse effects of metformin.
Details
In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin (103195).
|
Berberine can reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Details
Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam (34279).
|
Berberine might increase the sedative effect of pentobarbital.
Details
Evidence from animal research shows that berberine can prolong pentobarbital-induced sleeping time (13519). Theoretically, combining berberine and pentobarbital might increase the sedative effects of pentobarbital.
|
Berberine has been associated with increased blood levels of tacrolimus.
Details
In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL (91954).

Below is general information about the adverse effects of the known ingredients contained in the product Berberine 1200 mg. 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, berberine is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain and distension, constipation, diarrhea, flatulence, nausea, vomiting.
Intravenously: Facial flushing, painful swelling at the injection site.
Serious Adverse Events (Rare):
Intravenously: Ventricular tachycardia consistent with torsades de pointes.
Cardiovascular ...In four of 12 patients with refractory congestive heart failure, intravenous infusion of berberine at a rate of 0. 2 mg/kg per minute caused ventricular tachycardia consistent with torsades de pointes (33642).
Dermatologic
...When administered intravenously, berberine can cause painful swelling at the injection site or facial flushing (34330).
In three of 12 people injected subcutaneously with berberine, permanent hyperpigmentation at the injection site occurred (33698).
Orally, berberine may cause rash, but this event appears to be rare (34285,110106).
Endocrine ...Orally, berberine may cause hypoglycemia (111363).
Gastrointestinal ...Orally, berberine may cause diarrhea, constipation, flatulence, nausea, vomiting, abdominal pain, abdominal distention, gastroesophageal reflux, and bitter taste (33648,33689,34245,34247,34285,91953,99920,99921,103194,103197)(110106,111363,111699,113462).
Hepatic ...Orally, berberine may occasionally cause an increase in transaminases (99921,103194). However, meta-analyses have found no significant effect of berberine on alanine aminotransferase (ALT) or aspartate aminotransferase (AST) (104508,111363).
Musculoskeletal ...Reports of mild muscle pain and muscle weakness have been reported following the use of a combination product containing berberine, policosanol, red yeast rice, folic acid, coenzyme Q10, and astaxanthin (34283). It is unclear if these effects are due to berberine or other constituents.
Neurologic/CNS ...Orally, berberine may cause dizziness, drowsiness, fatigue, and headache (33648,99921,113462).
