Common Lipitor Drug Interactions: What You Need to Know

As one of the most widely prescribed cholesterol-lowering medications, Lipitor (atorvastatin) is a popular choice for millions of people worldwide. However, like any medication, Lipitor can interact with other drugs, which may affect its efficacy or increase the risk of side effects. In this article, we'll explore the common Lipitor drug interactions you should be aware of, and what you can do to minimize the risks.

Understanding Lipitor and Its Mechanism of Action

Before we dive into the drug interactions, it's essential to understand how Lipitor works. Lipitor is a statin, a class of medications that inhibit the production of cholesterol in the liver. By reducing the amount of cholesterol produced in the liver, Lipitor helps to lower low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, and increase high-density lipoprotein (HDL) cholesterol, also known as "good" cholesterol.
