Safety information
Safety information
Toxicity: Berberine generally tolerated but causes GI upset; important pregnancy/neonatal hazard (kernicterus risk).
Contraindications: Pregnancy and breastfeeding — avoid (berberine crosses placenta, displaces bilirubin -> kernicterus risk in neonates; uterine-stimulant reputation); neonates/infants — avoid.
Interactions: Berberine inhibits CYP3A4, CYP2D6 and P-glycoprotein -> raises levels of many drugs (cyclosporine, statins, midazolam); additive with antidiabetics/antihypertensives; caution with anticoagulants.
Pregnancy & breastfeeding: Avoid in pregnancy and lactation/neonates — kernicterus risk.
Evidence level
Supported by clinical trials in humans.
