Lipitor is a medication that is commonly prescribed to treat high cholesterol. According to Drug Patent Watch [1], Lipitor's active ingredient is atorvastatin, which works by blocking an enzyme that produces cholesterol in the liver. Although Lipitor is generally considered to be safe, some people may experience side effects.

The Mayo Clinic [2] lists several possible side effects of statins, including Lipitor. These side effects can include muscle pain, weakness, and tenderness. In rare cases, statins can cause a serious condition called rhabdomyolysis, which can lead to kidney damage. Other possible side effects include liver damage, digestive problems, and memory loss or confusion.

GoodRx [3] also notes that some people may experience side effects from statins like Lipitor. These side effects can include muscle pain, weakness, and tenderness, as well as stomach pain, nausea, and diarrhea. In rare cases, statins can cause serious side effects like liver damage and rhabdomyolysis.

If you are taking Lipitor or any other statin medication and are experiencing side effects, it is important to talk to your doctor. Your doctor can help you determine whether the benefits of the medication outweigh the risks and can work with you to find a treatment plan that works for you.
