Lipitor is a medication used to lower cholesterol levels in the body [1]. There is no evidence to suggest that taking Lipitor has any effect on flexibility in the body. However, it is important to note that taking Lipitor may have side effects such as muscle pain and weakness [2]. These side effects may affect one's ability to perform physical activities, which may impact flexibility. In addition, certain medical conditions such as hammertoes can also affect flexibility [3]. Therefore, it is important to consult with a healthcare provider if you experience any changes in flexibility while taking Lipitor or if you have any concerns about your overall health.
