⚠️ Mechanism
Licorice is a weak inhibitor of CYP2C9, which decreases metabolism of CYP2C9 substrates, potentially increasing their plasma concentrations and risk of adverse effects.
📋 Effect
Increased plasma levels of losartan (arb), potentially leading to toxicity or enhanced adverse effects.
💊 Management
Monitor for increased adverse effects of losartan. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.
Plain Language Summary
This combination can be moderately risky because licorice may prevent your body from breaking down your blood pressure medication properly. This can cause the medication to build up in your system, which may increase your risk of side effects.
