Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body. According to the Mayo Clinic [3], statins like Lipitor can cause side effects, including elevated liver enzymes. The article explains that liver enzyme levels should be monitored regularly while taking statins, as high levels could indicate liver damage. However, the article also notes that elevated liver enzymes are uncommon and usually not serious.

A study published in the American Journal of Cardiovascular Drugs [2] examined the safety of atorvastatin and found that it can cause mild elevations in liver enzymes. The study also notes that these elevations are usually temporary and do not cause any significant liver damage. The study recommends monitoring liver function tests in patients taking atorvastatin.

Drug Patent Watch [1] lists elevated liver enzymes as a potential adverse effect of atorvastatin. The website explains that while this side effect is rare, it can occur in some patients taking the drug.

In conclusion, Lipitor (atorvastatin) can cause elevated liver enzymes as a potential side effect, although it is rare and usually not serious. Patients taking Lipitor should have their liver enzyme levels monitored regularly to ensure that they do not experience any liver damage.
