Lipitor is a medication used to lower cholesterol levels and reduce the risk of heart disease. One of the potential side effects of taking Lipitor is liver damage, which can be detected through liver function tests [2]. However, the risk of developing liver damage from taking Lipitor is low and occurs in less than 1% of patients taking the medication [3]. It is recommended that patients taking Lipitor undergo liver function tests before starting the medication and periodically throughout treatment to monitor for any signs of liver damage [2]. If a patient experiences symptoms such as fatigue, abdominal pain, or yellowing of the skin or eyes while taking Lipitor, they should contact their healthcare provider immediately [3]. It is important to note that the benefits of taking Lipitor to reduce the risk of heart disease generally outweigh the potential risks associated with the medication [1].
