⚠️ Mechanism
Ginkgo is a weak inhibitor of CYP2D6, which decreases metabolism of CYP2D6 substrates, potentially increasing their plasma concentrations and risk of adverse effects.
📋 Effect
Increased plasma levels of dextromethorphan (antitussives), potentially leading to toxicity or enhanced adverse effects.
💊 Management
Monitor for increased adverse effects of dextromethorphan. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.
Plain Language Summary
This combination carries a moderate risk of side effects. Ginkgo can slow down how your body breaks down certain cough medicines, which may cause the medicine to build up to higher levels in your system.
