Lipitor is a medication used to lower cholesterol levels in the blood. However, it has been associated with some side effects, including liver damage. According to a study published in the Journal of Clinical and Diagnostic Research, liver function tests should be performed before and during treatment with Lipitor [2]. If liver function is affected, it is recommended to discontinue the medication and re-evaluate the patient's liver function after a few weeks [2]. The decision to discontinue Lipitor should be made by a healthcare professional based on the individual patient's circumstances.

It is important to note that discontinuing Lipitor may lead to an increase in cholesterol levels and increase the risk of heart disease [3]. Therefore, patients who are considering discontinuing Lipitor should discuss the risks and benefits with their healthcare provider.

In conclusion, if liver function is affected while taking Lipitor, it is recommended to discontinue the medication and re-evaluate the patient's liver function after a few weeks. However, the decision to discontinue Lipitor should be made by a healthcare professional based on the individual patient's circumstances. Patients who are considering discontinuing Lipitor should discuss the risks and benefits with their healthcare provider.
