Drug Interactions
Ezetimibe acts in the small intestine and has fewer systemic interactions than many lipid-lowering agents, but several remain clinically relevant.
- Statins (e.g., atorvastatin, simvastatin, rosuvastatin): Often co-administered for additive LDL lowering. The combination is well tolerated in most patients but slightly increases the risk of hepatic transaminase elevations and myopathy. Periodic LFT monitoring is appropriate.
- Bile acid sequestrants (e.g., cholestyramine, colesevelam, colestipol): Reduce ezetimibe absorption by approximately 55–80%. Administer ezetimibe at least 2 hours before or 4 hours after the bile acid sequestrant.
- Cyclosporine: Bidirectional interaction — cyclosporine increases ezetimibe exposure, and ezetimibe modestly increases cyclosporine levels. Monitor cyclosporine concentrations carefully when starting or stopping ezetimibe.
- Fibrates (e.g., fenofibrate, gemfibrozil): Increase ezetimibe plasma levels and cholelithiasis risk. Concurrent use with gemfibrozil is not recommended; fenofibrate combination is acceptable with caution.
- Warfarin: Rare INR elevations have been reported. Monitor INR after initiation and after dose changes.
