Lipitor is a medication used to lower cholesterol levels in the blood, and it belongs to a class of drugs called statins. Statins work by inhibiting an enzyme that is necessary for the production of cholesterol in the liver. Lipitor is generally well-tolerated, but like all medications, it can cause side effects [1]. One of the most common side effects of statins is muscle pain or weakness, which can be exacerbated by physical activity such as yoga [2]. However, a study published in the Journal of Clinical Lipidology found that statin-associated muscle symptoms can be effectively managed through the use of yoga and other exercise interventions [3]. The study suggests that yoga can help alleviate muscle pain and weakness associated with statin use, but it is important to consult with a healthcare provider before beginning any new exercise regimen, especially if you are taking medications like Lipitor.
