Lipitor (atorvastatin) is a medication that is commonly used to treat high cholesterol levels. Although it is generally well-tolerated, in rare cases, it can cause liver damage. If you are taking Lipitor and are experiencing symptoms of liver damage, it is important to seek medical attention right away.

Diagnosing Lipitor liver damage typically involves a series of tests. According to the National Center for Biotechnology Information [2], doctors will typically perform a liver function test (LFT) to determine if there is any damage to the liver. This test measures levels of various enzymes and proteins in the blood that are produced by the liver. If these levels are elevated, it could be a sign of liver damage.

In addition to the LFT, doctors may also perform an ultrasound or a CT scan to get a closer look at the liver and determine if there are any physical abnormalities. In some cases, a liver biopsy may be necessary to confirm a diagnosis of liver damage.

It is important to note that liver damage from Lipitor is rare, and most people who take the medication do not experience any problems. However, if you are taking Lipitor and are experiencing symptoms such as abdominal pain, yellowing of the skin or eyes, or dark urine, it is important to seek medical attention right away.
