Based on the information available, there is no general recommendation for patients on Lipitor (atorvastatin) to get liver function tests now [1]. Lipitor is a statin medication used to lower cholesterol levels, and while it can affect the liver, significant liver damage is rare [1][2].

The U.S. Food and Drug Administration (FDA) advises that routine monitoring of liver enzymes in patients on Lipitor is not necessary, except in specific cases [1]. These cases include patients with a history of liver disease or elevated liver enzymes [1].

However, healthcare professionals should be aware of the potential for liver enzyme elevations in patients taking Lipitor [1]. They should also inform patients to report any symptoms of liver problems, such as unusual fatigue, loss of appetite, abdominal pain, dark urine, or yellowing of the skin or eyes [1].

In summary, while Lipitor can affect liver function, routine liver function tests are not generally recommended for patients on this medication. Patients should consult their healthcare provider if they have concerns about their liver health or experience any symptoms of liver problems.
