Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Generally safe short-term for adults but contraindicated in specific groups and with some drugs.

warning notices

Most common adverse effects are gastrointestinal (constipation, diarrhea, flatulence, abdominal discomfort).
Not recommended for use during pregnancy or breastfeeding.
Risk of kernicterus in neonates due to interference with bilirubin metabolism.
May interact with many prescription drugs, especially those for diabetes, transplant, and blood thinners.
Rare cases of liver enzyme elevations reported.
Avoid use during pregnancy and breastfeeding due to risk of harm to fetus or infant.
Do not give to neonates or infants with jaundice or high bilirubin as it may cause kernicterus.
Use with caution if taking antidiabetic medications as berberine may enhance hypoglycemic effects; monitor blood sugar closely.
Use only under medical supervision if taking cyclosporine, anticoagulants, or drugs metabolized by CYP3A4, as berberine may alter drug levels.
Discontinue and consult a physician if signs of liver dysfunction (jaundice, dark urine, fatigue) arise during use.
