Lipitor is a brand name for the medication atorvastatin, which is used to lower cholesterol levels in the body. According to the Mayo Clinic [2], some of the common side effects of atorvastatin include headache, diarrhea, joint pain, and muscle pain. In rare cases, atorvastatin can cause serious side effects such as liver problems and a rare muscle disorder called rhabdomyolysis. GoodRx [3] states that muscle pain is a common side effect of statins, including atorvastatin, and can occur in up to 10% of patients taking the medication. However, there are steps that can be taken to prevent or alleviate muscle pain, such as exercising regularly, staying hydrated, and taking CoQ10 supplements. The specific discomfort caused by Lipitor or atorvastatin is likely to vary from person to person, and patients should always consult with their healthcare provider if they experience any side effects while taking the medication.
