The Importance of Liver Tests on Lipitor: A Guide to Recommended Frequency
As one of the most widely prescribed statins, Lipitor (atorvastatin) has been a cornerstone in the treatment of high cholesterol and heart disease for over two decades. However, like all medications, it carries a risk of liver damage, which is why regular liver tests are crucial for patients taking this medication. In this article, we will explore the recommended liver test frequency on Lipitor and what patients can expect.
What are Liver Tests?
Liver tests, also known as liver function tests (LFTs), are blood tests that measure the levels of certain enzymes and proteins in the blood to assess liver health. These tests can help diagnose liver damage, inflammation, or disease, and are often used to monitor the effects of medications on the liver.
Why are Liver Tests Important on Lipitor?
Lipitor, like all statins, can cause liver damage in some patients. This is because statins can increase the levels of liver enzymes, such as alanine transaminase (ALT) and aspartate transaminase (AST), which can indicate liver damage. Regular liver tests can help identify any potential liver problems early on, allowing for prompt treatment and minimizing the risk of liver damage.
