What liver tests are required before starting Lipitor?

Lipitor, also known as atorvastatin, is a prescription medication used to lower cholesterol and triglycerides in the blood [1]. Before starting Lipitor, it is essential to undergo liver function tests (LFTs) to ensure that the medication will not cause liver damage [2].

Why are liver tests necessary before Lipitor?

Atorvastatin, the active ingredient in Lipitor, can cause elevations in liver enzymes, which can indicate liver damage [3]. The FDA has required that patients taking atorvastatin undergo regular LFTs to monitor their liver health.

Which liver tests are required?

Two types of liver tests are commonly required before starting Lipitor:

1. Alanine Transaminase (ALT): This test measures the level of ALT in the blood, which can indicate liver cell damage.
2. Aspartate Transaminase (AST): This test measures the level of AST in the blood, which can also indicate liver cell damage.

The American Gastroenterological Association recommends that patients taking atorvastatin undergo regular LFTs, including ALT and AST tests, every 6-12 months [4].

What if the liver tests show elevated levels?

If the liver tests show elevated levels, your doctor may recommend a liver biopsy to rule out other conditions that may be causing the elevations [5]. Alternatively, your doctor may consider a different statin medication that has a lower risk of liver damage.

How can I get my liver tested before starting Lipitor?

Consult your doctor or healthcare provider to determine the best course of action for your specific situation. They will order the necessary LFTs, including ALT and AST tests, before starting you on Lipitor [6].
