Known interactions between the following drugs: Covera-HS, Lipitor

Verapamil may block the breakdown of atorvastatin by the liver. If this happens, blood levels of atorvastatin could be increased. This could cause a serious or potentially life-threatening side effect that involves the destruction of muscle tissue and could lead to kidney failure. Avoid using these drugs together if possible, However, if it is necessary to take verapamil and atorvastatin at the same time, you may be advised to watch for symptoms like unexplained muscle pain, tenderness, or weakness. If you are experiencing problems, your doctor may consider adjusting the dose of atorvastatin if needed or using an alternative to atorvastatin for reducing cholesterol. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
