Lipitor, also known as atorvastatin, is a medication commonly used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins, which work by blocking the production of cholesterol in the body [1]. The relationship between Lipitor and liver disease, however, is not as straightforward.

According to the U.S. National Library of Medicine, Lipitor has not been shown to cause or worsen liver disease [2]. In fact, it's metabolized in the liver, but it doesn't seem to affect liver function negatively. However, Lipitor's label does carry a warning about rare cases of liver enzyme elevations [3]. These elevations are usually mild and go away on their own, but in rare cases, they can lead to more serious liver problems.

It's important to note that Lipitor is not a treatment for liver disease. If you have liver disease, your doctor will likely monitor your liver function closely if you're prescribed Lipitor [2].

In conclusion, while Lipitor does not appear to cause or worsen liver disease, it's still crucial for individuals with liver disease to discuss with their healthcare provider before starting this medication.
