Lipitor Side Effects: What You Need to Know

As one of the most widely prescribed cholesterol-lowering medications, Lipitor (atorvastatin) has been a staple in the treatment of high cholesterol for decades. However, like any medication, it's not without its side effects. In this article, we'll delve into the common and rare side effects of Lipitor, as well as the potential risks associated with its use.

What is Lipitor?

Lipitor is a statin medication developed by Pfizer, first approved by the FDA in 1996. It works by inhibiting the production of cholesterol in the liver, thereby reducing the amount of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is often referred to as "bad" cholesterol because high levels of it can increase the risk of heart disease and stroke.

Common Side Effects of Lipitor

While Lipitor is generally considered safe and effective, it's not without its side effects. According to the FDA, the most common side effects of Lipitor include:

* Muscle pain and weakness: This is one of the most common side effects of Lipitor, affecting up to 10% of patients. Muscle pain and weakness can range from mild to severe and may be accompanied by muscle cramps, tenderness, and fatigue.
* Headache: Headaches are another common side effect of Lipitor, affecting up to 5% of patients. They can range from mild to severe and may be accompanied by other symptoms such as dizziness, nausea, and sensitivity to light.

Rare but Serious Side Effects of Lipitor

While the common side effects of Lipitor are generally mild and temporary, there are some rare but serious side effects that patients should be aware of. According to the FDA, these include:

* Rhabdomyolysis: This is a rare but serious side effect of Lipitor that can cause muscle damage and kidney failure. It's estimated to occur in less than 1% of patients taking Lipitor.
