Lipitor is a medication used to lower cholesterol levels and prevent heart disease. However, there are potential side effects associated with the use of Lipitor, including liver damage. According to the Mayo Clinic [3], some of the signs of liver damage include:

1. Fatigue
2. Loss of appetite
3. Upper abdominal pain
4. Dark urine
5. Jaundice (yellowing of the skin and eyes)

If any of these symptoms occur while taking Lipitor, it is important to seek medical attention immediately. In addition, regular liver function tests are recommended while taking Lipitor to monitor for any potential liver damage [2].

It is important to note that while liver damage is a potential side effect of Lipitor, it is relatively rare. According to Drug Patent Watch [1], less than 1% of patients experience liver damage while taking Lipitor.

In conclusion, while there is a potential risk of liver damage associated with Lipitor, it is a rare side effect. However, if any of the aforementioned symptoms occur while taking Lipitor, it is important to seek medical attention immediately. Additionally, regular liver function tests are recommended while taking Lipitor to monitor for any potential liver damage.
