Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease [3]. According to Drug Patent Watch [1], Lipitor is a prescription drug that has been approved by the FDA for use in adults and children over the age of 10. It is not recommended for pregnant women, nursing mothers, or individuals with liver problems.

In terms of safety before yoga practice, a study published in the National Library of Medicine [2] found that atorvastatin did not have a significant effect on physical performance or muscle strength in healthy individuals. However, it is important to note that this study was conducted on a small sample size and further research is needed to determine the effects of atorvastatin on physical activity.

Everyday Health [3] states that common side effects of Lipitor include muscle pain, diarrhea, and nausea. In rare cases, it can cause more serious side effects such as liver damage or muscle breakdown. It is important to talk to a healthcare provider before taking Lipitor or any medication before engaging in physical activity.

In conclusion, Lipitor is a prescription medication used to lower cholesterol levels and reduce the risk of heart disease. While a small study found that it did not have a significant effect on physical performance or muscle strength, it is important to talk to a healthcare provider before taking Lipitor or any medication before engaging in physical activity. Additionally, Lipitor can cause side effects such as muscle pain, diarrhea, and nausea, and in rare cases, more serious side effects such as liver damage or muscle breakdown [1][2][3].
