Lipitor is a medication used to lower cholesterol levels in the blood. While it is generally well-tolerated, it can cause liver damage in rare cases. As a result, liver function tests are often recommended for patients taking Lipitor [3]. However, there is no specific liver function test for Lipitor [2]. Instead, doctors typically order a standard liver function test, which measures levels of certain enzymes and proteins in the blood that can indicate liver damage [3]. It is important for patients taking Lipitor to have regular liver function tests to monitor for any potential liver damage [1]. If a patient experiences symptoms such as abdominal pain, yellowing of the skin or eyes, or dark urine while taking Lipitor, they should contact their doctor immediately [3].
