Lipitor is a medication used to lower cholesterol levels in the blood, and it is generally well-tolerated by most people. However, there are some potential side effects associated with taking Lipitor, including muscle pain, weakness, and difficulty breathing [3]. In rare cases, Lipitor can cause a condition called rhabdomyolysis, which can lead to kidney failure and difficulty breathing [3].

While there is no direct evidence linking Lipitor dosage to breathing difficulties during yoga, it is important to be aware of the potential side effects of the medication. If you experience any unusual symptoms while taking Lipitor, including difficulty breathing, it is important to speak with your healthcare provider right away [2].

In general, it is always a good idea to talk to your healthcare provider before starting any new exercise program, especially if you have any underlying health conditions or are taking any medications. Your healthcare provider can help you determine if yoga is a safe and appropriate form of exercise for you, and can provide guidance on how to modify your practice if needed [2].
