⚠️ 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 sildenafil (pde5-inhibitors), potentially leading to toxicity or enhanced adverse effects.
💊 Management
Monitor for increased adverse effects of sildenafil. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.
Plain Language Summary
This combination may be unsafe as it can increase the risk of side effects. Dong Quai can slow down how your body breaks down PDE5 inhibitors, which may cause higher levels of the medication to build up in your bloodstream.
