Lipitor is a prescription medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins, which work by blocking the enzyme responsible for producing cholesterol in the liver [1]. While Lipitor is generally considered safe, there are potential risks associated with its use, including liver damage. As a result, liver monitoring is recommended for patients taking Lipitor [2].

In 2012, the FDA issued a drug safety communication regarding important safety label changes for cholesterol-lowering statin drugs, including Lipitor. The communication warned that statins could cause liver damage and that liver function tests should be performed before starting treatment and as needed thereafter [2].

A recent study published in the Journal of Clinical Lipidology also highlights the importance of liver monitoring for patients taking statins. The study found that patients taking statins were at a higher risk of developing liver dysfunction, and that liver function tests should be performed regularly to detect any abnormalities [3].

In conclusion, while Lipitor is generally considered safe, there are potential risks associated with its use, including liver damage. Therefore, liver monitoring is recommended for patients taking Lipitor. The FDA has issued a drug safety communication warning of the potential for liver damage and recommending liver function tests before starting treatment and as needed thereafter. A recent study also highlights the importance of regular liver monitoring for patients taking statins.
