Lipitor is a medication used to lower cholesterol levels in the blood, and it is not directly related to muscle spasms or cramps [1]. However, muscle cramps and spasms are common side effects of statins, a class of drugs that includes Lipitor [2]. Therefore, it is important to talk to a doctor about any muscle cramps or spasms experienced while taking Lipitor.

Stretching can be helpful in managing muscle cramps and spasms, but it is not clear how often one should stretch while taking Lipitor. According to a study published in the Journal of Clinical Medicine Research, exercise can help alleviate muscle symptoms associated with statin use [3]. Therefore, it may be beneficial to incorporate stretching and exercise into a daily routine while taking Lipitor. However, it is important to talk to a doctor before starting any new exercise program.

In summary, Lipitor is not directly related to muscle spasms or cramps, but these can be common side effects of the medication. Stretching and exercise may be helpful in managing these symptoms, but it is important to talk to a doctor before starting any new exercise program.
