Lipitor is a medication used to lower cholesterol levels in the body, and its active ingredient is atorvastatin. According to the Mayo Clinic [3], statins, including Lipitor, can cause liver damage, but it is rare. The liver function should be monitored regularly while taking Lipitor, especially if there is a history of liver disease or alcohol abuse. The liver function can be measured through blood tests that check for liver enzymes. If the liver enzymes are elevated, the doctor may adjust the Lipitor dosage or discontinue the medication.

Medical News Today [2] reports that Lipitor can cause mild liver damage, but it is not common. Symptoms of liver damage include fatigue, loss of appetite, dark urine, and jaundice. If these symptoms occur, it is essential to seek medical attention immediately.

Drug Patent Watch [1] provides information on Lipitor's clinical trials, which showed that less than 1% of patients taking Lipitor experienced elevated liver enzymes. However, the trials also revealed that patients taking higher doses of Lipitor had a higher risk of developing liver damage.

In conclusion, while Lipitor can cause liver damage, it is rare. It is essential to monitor liver function regularly while taking Lipitor, especially if there is a history of liver disease or alcohol abuse. If symptoms of liver damage occur, seek medical attention immediately.
