Why are liver enzymes an important concern for Accutane patients?
Accutane, also known as isotretinoin, is a powerful oral retinoid medication used primarily for treating severe acne. One of the potential risks associated with Accutane is liver damage or elevation of liver enzymes [1]. To monitor this risk, patients on Accutane undergo regular liver function tests.
What liver enzyme monitoring rules apply to Accutane patients?
According to the prescribing information and recommendations from the FDA, Accutane patients should have a complete blood count (CBC) and liver function tests (LFTs) at the beginning of treatment and then at weekly intervals for the first month, and at monthly intervals thereafter. LFTs should include measurements of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and alkaline phosphatase [2].
What happens if liver enzyme levels become elevated?
If a patient's liver enzyme levels become elevated, their physician will closely monitor their condition and consider discontinuing or stopping the medication. Severe liver damage can occur with prolonged use of Accutane, even with normal or mildly elevated liver enzymes [3].
Are there specific guidelines for patients with pre-existing liver conditions?
Yes, patients with pre-existing liver conditions, such as liver disease or elevated liver enzymes, or those taking medications that affect liver function, should receive special consideration when starting Accutane. These patients may need more frequent monitoring of their liver enzymes and other lab values to ensure the medication is safe for them to use [4].
How can patients prevent liver damage while taking Accutane?
While on Accutane, it is essential to follow a healthy lifestyle and avoid potential liver toxins. Patients should also inform their healthcare provider about any medications they are taking, especially those that could be detrimental to the liver.
