Lipitor is a medication that is used to lower cholesterol levels in the blood [1]. According to a study published in the US National Library of Medicine, Lipitor is generally well-tolerated and safe for most people. However, some people may experience side effects such as muscle pain, weakness, and cramping [2]. These side effects can make it difficult to perform physical activities, such as yoga, that require a lot of physical exertion.

Breathing is an essential aspect of yoga practice, and any medication that affects breathing can potentially impact yoga performance. However, there is no evidence to suggest that Lipitor directly affects breathing during yoga practice.

That being said, it is essential to note that doing too much yoga or pushing oneself too hard during yoga practice can be risky [3]. This can lead to shortness of breath, dizziness, and other adverse effects. It is always advisable to consult with a healthcare provider before starting any new exercise routine, especially if you are taking medication.

In conclusion, Lipitor is a medication that is used to lower cholesterol levels in the blood. While Lipitor may cause muscle pain, weakness, and cramping, there is no evidence to suggest that it directly affects breathing during yoga practice. However, it is essential to consult with a healthcare provider before starting any new exercise routine, especially if you are taking medication [1][2][3].
