Unfortunately, the sources provided do not provide information on how often Lipitor should be taken during yoga. Lipitor is a medication used to lower cholesterol levels in the blood, and the recommended dosage and frequency of use are determined by a healthcare provider based on individual patient needs and medical history [1]. It is important to follow the instructions provided by the healthcare provider and the medication label for safe and effective use of Lipitor.

However, it is worth noting that some individuals may experience muscle pain or weakness as a side effect of taking statins like Lipitor. In such cases, it is recommended to consult with a healthcare provider to adjust the dosage or switch to a different medication [2][3]. Additionally, incorporating yoga or other low-impact exercises into a daily routine may help alleviate muscle pain associated with statin use [3].
