Lipitor is a medication used to treat high cholesterol levels and prevent heart disease [2]. Like all medications, Lipitor can cause side effects. Some of the most common side effects of Lipitor include muscle and joint pain, diarrhea, constipation, and nausea [2]. In rare cases, Lipitor can cause more serious side effects such as liver problems, allergic reactions, and muscle damage [2].

According to the FDA label for Lipitor, muscle problems are the most common side effect of the medication [3]. Patients taking Lipitor may experience muscle pain, weakness, or tenderness. In rare cases, Lipitor can cause a condition called rhabdomyolysis, which is a breakdown of muscle tissue that can lead to kidney damage or failure [3].

Patients taking Lipitor should also be aware of the potential for liver problems. In rare cases, Lipitor can cause an increase in liver enzymes, which can indicate liver damage [3]. Patients should report any symptoms of liver problems, such as yellowing of the skin or eyes, to their healthcare provider.

It is important for patients taking Lipitor to be aware of the potential side effects and to report any symptoms to their healthcare provider. Patients should also follow their healthcare provider's instructions for taking Lipitor and have regular check-ups to monitor their cholesterol levels and overall health [2].
