Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the body. While statins like Lipitor are generally considered safe and effective, there are potential side effects associated with their use, including liver damage. According to the Mayo Clinic [3], liver damage is a rare but serious side effect of statins like Lipitor. Symptoms of liver damage may include fatigue, loss of appetite, dark urine, and yellowing of the skin or eyes. Patients taking Lipitor should have their liver function monitored regularly by a healthcare provider to detect any potential problems early on. However, it is important to note that the risk of liver damage from Lipitor is relatively low, and most people can take the drug without experiencing any serious side effects [2]. Overall, while there is a potential risk of liver damage associated with Lipitor use, this risk is generally outweighed by the drug's benefits in reducing cholesterol levels and preventing heart disease.
