Lipitor, also known as atorvastatin, is a commonly prescribed medication used to lower cholesterol levels and reduce the risk of heart disease [1]. However, it is important to note that like any medication, Lipitor can cause side effects, including liver damage [2].

According to the Mayo Clinic, liver damage is a rare but potentially serious side effect of statins, the class of drugs to which Lipitor belongs [3]. The risk of liver damage is higher in people who already have liver disease or who consume large amounts of alcohol [3]. For this reason, people with existing liver conditions should be closely monitored by their healthcare provider while taking Lipitor or any other statin medication [3].

Medical News Today reports that Lipitor can cause an increase in liver enzymes, which can be a sign of liver damage [2]. However, the article notes that this side effect is usually mild and temporary, and does not typically lead to long-term liver damage [2].

In summary, Lipitor can potentially worsen existing liver conditions, particularly in people with liver disease or who consume large amounts of alcohol. However, liver damage is a rare side effect of the medication, and is usually mild and temporary. People with existing liver conditions should be closely monitored by their healthcare provider while taking Lipitor or any other statin medication.
