⚠️ Mechanism
Dong Quai is a weak inhibitor of CYP3A4, which decreases metabolism of CYP3A4 substrates, potentially increasing their plasma concentrations and risk of adverse effects.
📋 Effect
Increased plasma levels of cyclosporine (immunosuppressants), potentially leading to toxicity or enhanced adverse effects.
💊 Management
Monitor for increased adverse effects of cyclosporine. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.
Plain Language Summary
This combination is dangerous because Dong Quai can prevent your body from breaking down immunosuppressant drugs properly. This may cause the medication to build up to unsafe levels in your bloodstream, increasing the risk of serious side effects.
