Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. While it is generally considered safe, there are potential side effects, including liver damage. According to the Mayo Clinic [3], the symptoms of liver damage may include:

- Fatigue and weakness
- Loss of appetite
- Upper abdominal pain
- Dark urine
- Yellowing of the skin and eyes (jaundice)

Liver damage is a rare side effect of statins, including Lipitor, but it is important to monitor for these symptoms if you are taking the medication. If you experience any of these symptoms, it is important to contact your healthcare provider immediately.

According to a study published in the National Center for Biotechnology Information [2], liver damage caused by statins is usually mild and reversible. However, in rare cases, it can lead to serious liver problems, such as liver failure.

It is important to note that liver damage is not the only potential side effect of Lipitor. Other side effects may include muscle pain, memory loss, and an increased risk of diabetes. As with any medication, it is important to weigh the potential benefits against the potential risks and to discuss any concerns with your healthcare provider.
