Known Drug Interactions

major amlodipine

For patients taking amiodarone, amlodipine, or ranolazine, do not exceed VYTORIN 10/20 mg daily [see Dosage and Administration (2.3) ] .

Mechanism: Amlodipine can cause the cholesterol medication to stay in your system longer, which increases the chance of muscle pain or weakness.

What to do: Your daily dose of ezetimibe and simvastatin should be limited to 10 mg/20 mg to prevent muscle problems.

major diltiazem

Intervention: For patients taking verapamil, diltiazem, or dronedarone, do not exceed VYTORIN 10/10 mg daily.

Mechanism: Diltiazem slows down the breakdown of simvastatin in your body, which can lead to higher levels of the drug in your blood. This increases the risk of serious muscle damage.

What to do: Do not take more than 10/10 mg of VYTORIN daily if you are also taking diltiazem.

major verapamil

Intervention: For patients taking verapamil, diltiazem, or dronedarone, do not exceed VYTORIN 10/10 mg daily.

Mechanism: Verapamil prevents your body from processing simvastatin correctly, causing the drug to build up to high levels. This can lead to severe muscle pain or weakness.

What to do: Your doctor should limit your VYTORIN dose to 10/10 mg daily while you are on verapamil.

major cyclosporine

Cyclosporine, Danazol, or Gemfibrozil Clinical Impact: The risk of myopathy and rhabdomyolysis is increased with concomitant use of cyclosporine, danazol, or gemfibrozil with VYTORIN. Intervention: Concomitant use of cyclosporine, danazol, or gemfibrozil with VYTORIN is contraindicated [see Contraindications (4) ] .

Mechanism: Cyclosporine causes a large increase in simvastatin levels in your blood, which can lead to a dangerous condition where muscle tissue breaks down.

What to do: You should not take these two medications together at the same time.

major amiodarone

Amiodarone, Dronedarone, Ranolazine, or Calcium Channel Blockers Clinical Impact: The risk of myopathy and rhabdomyolysis is increased by concomitant use of amiodarone, dronedarone, ranolazine, or calcium channel blockers with VYTORIN. For patients taking amiodarone, amlodipine, or ranolazine, do not exceed VYTORIN 10/20 mg daily [see Dosage and Administration (2.3) ] .

Mechanism: Amiodarone slows the removal of simvastatin from your system, which increases the risk of muscle injury.

What to do: Your daily dose of VYTORIN should not exceed 10/20 mg if you are taking amiodarone.
