Lipitor, a medication commonly prescribed to manage high cholesterol, can impact liver enzymes and tests. According to the Mayo Clinic, statins like Lipitor can increase levels of certain liver enzymes, which are measured through liver function tests [3].

The U.S. Food and Drug Administration (FDA) mandates liver enzyme tests before starting Lipitor and periodically while on the medication [3]. This is to ensure that the drug is not causing harmful effects on the liver.

A study published in the Journal of Clinical and Diagnostic Research found that Lipitor can cause a mild to moderate increase in liver enzymes, but these usually return to normal after discontinuation of the drug [1]. However, the study also notes that severe liver damage due to Lipitor is rare [1].

The drug patent watch website provides information on Lipitor's approved uses, side effects, and warnings [2]. It states that Lipitor can cause abnormal liver function tests, but serious liver damage is uncommon [2].

In conclusion, Lipitor can impact liver enzymes and tests, often causing a mild to moderate increase in liver enzymes. However, severe liver damage is rare. It is important to have liver function tests before starting Lipitor and periodically while on the medication to monitor for any potential liver damage.
