Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor was first approved by the FDA in 1996 and has been widely prescribed since then. However, one of the common side effects of this medication is muscle pain or weakness, which can be exacerbated by physical activity such as yoga.

Muscle pain is a well-known side effect of statins, including Lipitor. According to a Harvard Health Publishing article [2], muscle pain or weakness is a common complaint among patients taking statins, and it can range from mild discomfort to severe pain. This pain can be especially pronounced during physical activity, such as yoga. The article suggests that one way to manage statin-related muscle pain is to reduce the intensity of physical activity or switch to low-impact exercises.

A study published in the Journal of Clinical Lipidology [3] investigated the relationship between statin use and exercise-related muscle pain. The study found that muscle pain was more common among patients taking statins compared to those who were not taking the medication. However, the study also found that exercise-related muscle pain was not a significant predictor of discontinuing statin therapy. The authors suggest that the benefits of statin therapy may outweigh the potential side effects for many patients.

In conclusion, Lipitor can cause muscle pain, and this pain can be exacerbated by physical activity such as yoga. Patients who experience muscle pain while taking Lipitor should talk to their healthcare provider about managing their symptoms. While reducing the intensity of physical activity or switching to low-impact exercises may help, it is important to weigh the potential benefits and risks of statin therapy for each individual patient.
