Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels and reduce the risk of heart disease and stroke [1]. According to a study published in the Journal of Clinical Lipidology, atorvastatin has been shown to cause elevations in liver enzymes in some patients [3]. Liver enzymes are proteins that are produced by the liver and are involved in various metabolic processes in the body. Elevated liver enzymes can be a sign of liver damage or inflammation.

The study found that atorvastatin can cause elevations in liver enzymes, particularly alanine aminotransferase (ALT) and aspartate aminotransferase (AST), in some patients. However, the elevations were generally mild and temporary, and most patients did not experience any symptoms or liver damage [3].

According to Medical News Today, some of the common side effects of Lipitor include headache, muscle pain, diarrhea, and nausea. However, liver problems are a rare but serious side effect of the medication, and patients should seek medical attention if they experience symptoms such as yellowing of the skin or eyes, dark urine, or abdominal pain [2].

In conclusion, atorvastatin (Lipitor) can cause elevations in liver enzymes in some patients, but these elevations are generally mild and temporary, and most patients do not experience any symptoms or liver damage. However, liver problems are a rare but serious side effect of the medication, and patients should seek medical attention if they experience any symptoms of liver damage.
