Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. While it is generally well-tolerated by most patients, it can cause side effects, including liver problems [3]. The medication works by blocking an enzyme in the liver that is responsible for producing cholesterol [2]. This can cause an increase in liver enzymes, which can be an indication of liver damage [3].

In rare cases, Lipitor can cause serious liver problems, such as hepatitis and liver failure [2]. Patients who experience symptoms such as yellowing of the skin or eyes, dark urine, or persistent nausea and vomiting should seek medical attention immediately [3].

It is important for patients taking Lipitor to have regular liver function tests to monitor for any potential liver problems [2]. Patients who have a history of liver disease or heavy alcohol use should use caution when taking Lipitor and discuss the risks and benefits with their healthcare provider [3].

In conclusion, while Lipitor is an effective medication for lowering cholesterol levels, it can cause liver problems in some patients. Patients should be aware of the potential side effects and discuss any concerns with their healthcare provider. Regular liver function tests are important for monitoring liver health while taking Lipitor [2][3].
