Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the blood [1]. While taking Lipitor, it is important to monitor liver function tests as it may cause liver damage. Liver function tests measure the levels of certain enzymes and proteins in the blood that indicate how well the liver is functioning. If the liver is not functioning properly, it can lead to serious health problems.

According to the Mayo Clinic, statins like Lipitor can cause liver damage in some people. However, the risk of liver damage is rare and usually occurs in people who have preexisting liver disease or who take high doses of the medication [2]. Therefore, it is important to monitor liver function tests before starting Lipitor and periodically while taking it.

A recent study published in the Journal of Clinical Medicine Research found that Lipitor can cause liver damage in some patients, but the incidence is low. The study recommends monitoring liver function tests before starting Lipitor and then periodically during treatment [3].

In conclusion, while taking Lipitor, it is important to monitor liver function tests to ensure that the liver is functioning properly. Although the risk of liver damage is rare, it is important to take precautions and monitor liver function tests before and during treatment with Lipitor.
