Lipitor is a medication used to treat high cholesterol levels. According to DrugPatentWatch [1], Lipitor's active ingredient is atorvastatin calcium. Lipitor is a statin drug, which means it works by blocking the production of cholesterol in the liver. However, like all medications, Lipitor may cause side effects, and liver damage is one of them.

According to Mayo Clinic [2], statins, including Lipitor, may cause liver damage. However, this is rare, and the risk is generally low. In most cases, liver damage caused by statins is mild and reversible. However, in rare cases, statins can cause serious liver damage, leading to liver failure.

Medical News Today [3] also notes that Lipitor can cause liver damage, but it is a rare side effect. The article explains that patients taking Lipitor should have their liver function tested regularly to monitor for any potential liver damage.

In conclusion, Lipitor may cause liver damage, but the risk is generally low. Patients taking Lipitor should have their liver function tested regularly to monitor for any potential liver damage. If a patient experiences any symptoms of liver damage, such as yellowing of the skin or eyes, dark urine, or abdominal pain, they should contact their doctor immediately.
