Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor is FDA approved for use in patients with high cholesterol, and it is not recommended for patients with liver problems. However, the Mayo Clinic [3] states that some people with liver disease can take statins, including Lipitor, but it should be done with caution and under the supervision of a doctor. The Medical News Today [2] article notes that liver problems are listed as a potential side effect of taking Lipitor, and that individuals with a history of liver disease or heavy alcohol use should inform their doctor before taking the medication.

In summary, while Lipitor is not recommended for use in patients with liver problems, some people with liver disease can take statins, including Lipitor, under the supervision of a doctor. It is important for individuals with liver disease or a history of liver problems to inform their doctor before taking Lipitor, as liver problems are listed as a potential side effect of the medication.
