Lipitor and Your Current Meds: Understanding the Interactions and Contraindications
As one of the most widely prescribed cholesterol-lowering medications, Lipitor (atorvastatin) is often used in combination with other medications to manage cardiovascular health. However, it's essential to understand the potential interactions and contraindications between Lipitor and your current medications to ensure safe and effective treatment.
What is Lipitor?
Lipitor is a statin medication used to lower low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, in the blood. It works by inhibiting the production of cholesterol in the liver, which helps to reduce the amount of cholesterol produced in the body.

* Niacin: Lipitor may increase the risk of myopathy when taken with niacin (vitamin B3).
* Other statins: Lipitor may increase the risk of myopathy when taken with other statins, such as simvastatin (Zocor) or lovastatin (Mevacor).
