Lipitor is a medication used to lower cholesterol levels in the body [1]. However, it can also have side effects such as muscle pain, weakness, and fatigue [2]. According to the Mayo Clinic, exercise can help reduce cholesterol levels in the body, but it is not clear if it can counteract the side effects of Lipitor [2]. Additionally, stopping Lipitor without consulting a doctor can lead to an increased risk of heart disease and stroke [3]. Therefore, it is important to talk to a healthcare provider about any concerns regarding the side effects of Lipitor and whether exercise or other interventions can be used in conjunction with the medication [2][3].
