There is no evidence of reported side effects with Lipitor during yoga. Lipitor is a medication used to lower cholesterol levels in the blood [1]. While muscle pain is a common side effect of statins, including Lipitor, it is not specifically linked to practicing yoga [2]. In fact, yoga may even help alleviate muscle pain caused by statins by improving flexibility and reducing inflammation [3]. However, it is always important to consult with a healthcare provider before starting any new exercise routine or making changes to medication use.
