Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. According to the Mayo Clinic, Lipitor can cause liver damage, but it is a rare side effect. The clinic advises patients to inform their doctors immediately if they experience symptoms such as fatigue, loss of appetite, abdominal pain, dark urine, or yellowing of the skin or eyes, as these may indicate liver damage [3].

A study published in the US National Library of Medicine found that atorvastatin can cause mild to moderate liver enzyme elevations in some patients. However, the study concluded that the incidence of liver enzyme elevations with atorvastatin was similar to that of other statins and that it was not a significant clinical concern [2].

In summary, Lipitor can cause liver damage, but it is a rare side effect. The medication can also cause mild to moderate liver enzyme elevations, but this is not a significant clinical concern. Patients taking Lipitor should inform their doctors immediately if they experience any symptoms of liver damage [2][3].
