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 medication that was first approved by the FDA in 1996 and is still under patent protection until 2020. The medication works by inhibiting the production of cholesterol in the liver, which can help reduce the risk of heart attack, stroke, and other cardiovascular diseases [3].

As for whether it is safe to take Lipitor before yoga, the article from Everyday Health [3] does not mention any specific risks associated with taking Lipitor before physical activity like yoga. However, it is always recommended to consult with a healthcare provider before starting any new exercise routine or taking any new medications.

The article from the National Center for Biotechnology Information [2] does mention some potential side effects of Lipitor, including muscle pain and weakness. In rare cases, these side effects can lead to a condition called rhabdomyolysis, which can cause kidney damage. However, the article notes that these side effects are relatively uncommon and that most people tolerate the medication well.

In conclusion, Lipitor is a prescription medication used to lower cholesterol levels and reduce the risk of heart disease. While there is no specific information about the safety of taking Lipitor before yoga, it is always recommended to consult with a healthcare provider before starting any new exercise routine or taking any new medications. The medication may cause some potential side effects, including muscle pain and weakness, but these are relatively uncommon [2][3].
