Lipitor is a medication that is commonly used to lower cholesterol levels in the blood. According to the Mayo Clinic [3], Lipitor is a statin drug that works by blocking an enzyme in the liver that is responsible for producing cholesterol. While Lipitor is generally considered safe and effective, there are some potential side effects that patients should be aware of.

One of the potential side effects of Lipitor is liver damage. According to Medical News Today [2], Lipitor can cause an increase in liver enzymes, which can be a sign of liver damage. However, the article notes that this side effect is rare and usually reversible once the medication is discontinued.

Drug Patent Watch [1] also notes that liver damage is a potential side effect of Lipitor, but it is listed as a rare side effect in the drug's prescribing information. The website notes that liver damage is more likely to occur in patients who have pre-existing liver disease or who consume alcohol while taking the medication.

It is important to note that while liver damage is a potential side effect of Lipitor, it is not a common occurrence. Patients who are taking Lipitor should be aware of the signs of liver damage, such as yellowing of the skin or eyes, abdominal pain, or dark urine, and should contact their healthcare provider if they experience any of these symptoms.

In conclusion, Lipitor can cause liver damage, but it is a rare side effect and is usually reversible once the medication is discontinued. Patients who are taking Lipitor should be aware of the signs of liver damage and should contact their healthcare provider if they experience any symptoms.
