Lipitor is a medication used to treat high cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor is a brand name for the generic drug Atorvastatin, which works by blocking an enzyme that produces cholesterol in the liver. However, like any other medication, Lipitor may have side effects that may affect individuals differently.

CNN reports [2] that a study published in the Journal of the American Medical Association (JAMA) revealed that some people may experience muscle pain, diabetes, and other side effects while taking statins, including Lipitor. However, the study also showed that the benefits of taking statins outweigh the risks, especially for those who are at high risk of heart disease.

Medical News Today [3] also states that Lipitor may cause side effects such as headache, nausea, diarrhea, muscle pain, and weakness. Some people may also experience liver damage, memory loss, and confusion. However, these side effects are rare, and most people who take Lipitor do not experience any significant problems.

Therefore, if you have stopped taking Lipitor and noticed any changes in your body, it is essential to consult your doctor. They can help determine if the changes are related to the medication or if there are other underlying health issues that need to be addressed.
