Lipitor is a brand name for the drug atorvastatin, which is a statin medication used to lower cholesterol levels in the body. Although generally safe, like any medication, Lipitor may cause side effects, including liver damage.

According to the Mayo Clinic [3], the symptoms of liver damage may include:

- Fatigue
- Weakness
- Loss of appetite
- Yellowing of the skin and eyes (jaundice)
- Dark urine
- Pale stools
- Pain or swelling in the abdomen
- Nausea and vomiting

The Medical News Today [2] article notes that Lipitor can cause liver damage in rare cases. It is important to seek medical attention immediately if you experience any of the symptoms mentioned above while taking Lipitor.

Drug Patent Watch [1] also notes that liver function tests should be monitored regularly in patients taking Lipitor, as elevated liver enzymes may be a sign of liver damage.

In summary, while Lipitor is generally safe, liver damage can occur in rare cases. Symptoms of liver damage may include fatigue, weakness, loss of appetite, jaundice, dark urine, pale stools, pain or swelling in the abdomen, nausea, and vomiting. If you experience any of these symptoms while taking Lipitor, seek medical attention immediately. Regular liver function tests should also be performed in patients taking Lipitor.
