Licorice × Antiplatelet Drugs

MODERATE INTERACTION

⚠️ Mechanism

Licorice is a weak inhibitor of CYP2C19, which decreases metabolism of CYP2C19 substrates, potentially increasing their plasma concentrations and risk of adverse effects.

📋 Effect

Increased plasma levels of clopidogrel (antiplatelet-drugs), potentially leading to toxicity or enhanced adverse effects.

💊 Management

Monitor for increased adverse effects of clopidogrel. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.

Plain Language Summary

This combination carries a moderate risk because licorice can cause antiplatelet drugs to build up to higher levels in your bloodstream. This increase in medication levels may lead to a higher risk of experiencing side effects.
