Lipitor, the brand name for the drug atorvastatin, is a medication used to lower cholesterol levels in the blood. While it is generally considered safe and effective, it can cause side effects in some people. One of the potential side effects of Lipitor is liver damage. According to the Mayo Clinic [3], Lipitor can cause an increase in liver enzymes, which can be a sign of liver damage. In rare cases, Lipitor can cause liver failure, which can be life-threatening. However, this is a rare side effect, and most people who take Lipitor do not experience any liver problems. It is important to note that people who have a history of liver disease or heavy alcohol use should not take Lipitor. Additionally, people who experience symptoms of liver damage, such as yellowing of the skin or eyes, dark urine, or abdominal pain, should contact their doctor right away.
