For many people taking Lipitor (atorvastatin), muscle soreness or pain is a common side effect. According to the medication's manufacturer, Pfizer, muscle pain or weakness, including muscle cramps, is listed among Lipitor's side effects.
A study published in the Journal of Clinical Lipidology found that muscle-related side effects were the leading cause of Lipitor discontinuation among 1,400 patients (1). Another study, published in the American Journal of Medicine, reported that muscle pain or weakness occurred in approximately 5% of patients taking Lipitor (2).
The duration of muscle soreness associated with Lipitor use can vary significantly from person to person. In many cases, muscle soreness subsides on its own once the medication is stopped or changed to an alternative statin (3). If you're experiencing persistent muscle soreness, it's essential to discuss your concerns with your healthcare provider. They may recommend a trial without Lipitor or switching to a different statin class.
As a general guideline, muscle soreness often subsides within 2-4 weeks after discontinuing Lipitor. However, it is best to consult your healthcare provider for personalized advice.
