Lipitor Interactions: What You Need to Know

As one of the most widely prescribed cholesterol-lowering medications, Lipitor (atorvastatin) has been a staple in many people's treatment plans for decades. However, like any medication, it's essential to be aware of potential interactions with other drugs to ensure safe and effective treatment. In this article, we'll delve into the known interactions between Lipitor and other medications, exploring the potential risks and benefits.

What is Lipitor?

Before we dive into the interactions, let's quickly review what Lipitor is and how it works. Lipitor is a statin medication that belongs to the HMG-CoA reductase inhibitor class. It works by reducing the production of low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, in the liver. This helps to lower overall cholesterol levels and reduce the risk of heart disease.
