Abstract
BACKGROUND

Isotretinoin is a widely prescribed drug for various dermatological conditions, especially acne. Blood tests are routinely performed to monitor its side effects. However, the optimal testing schedule remains controversial.

AIM

To evaluate the laboratory monitoring tests and schedules of patients with acne taking isotretinoin to determine the most efficient testing regimen.

METHODS

We retrospectively reviewed electronic medical records from the Dermatology Department of Dongguk University Ilsan Hospital from 2005 to 2020 for patients prescribed isotretinoin for acne who underwent monthly blood tests.

RESULTS

Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and triglyceride (TG) levels significantly changed between 5 and 6 mo when the total prescription period and dose variables were considered altogether. The high-density lipoprotein level also significantly changed between 5 and 6 mo. However, low-density lipoprotein (LDL) and total cholesterol levels significantly changed between 1 and 2 mo.

CONCLUSION

We recommend testing AST, ALT, and TG levels once every 5 to 6 mo. We also suggest testing LDL and total cholesterol levels during the first and second months.

Core Tip: Isotretinoin is a widely prescribed drug for various dermatological conditions, especially acne. Blood tests are routinely performed to monitor its side effects. However, the optimal testing schedule remains controversial. This study investigated the optimal blood test type and frequency for patients taking isotretinoin for acne. This article will contribute to Asian-specific isotretinoin laboratory guidelines and further studies.
