BACKGROUND Isotretinoin is a widely prescribed drug for various dermatological conditions,especially *** tests are routinely performed to monitor its side ***,the optimal testing schedule remains *** To evaluate the laboratory monitoring tests and schedules of patients with acne taking isotretinoin to determine the most efficient testing *** 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 *** Aspartate aminotransferase(AST),alanine aminotransferase(ALT),and trigly-ceride(TG)levels significantly changed between 5 and 6 mo when the total prescription period and dose variables were considered *** high-density lipoprotein level also significantly changed between 5 and 6 ***,low-density lipoprotein(LDL)and total cholesterol levels significantly changed between 1 and 2 *** We recommend testing AST,ALT,and TG levels once every 5 to 6 *** also suggest testing LDL and total cholesterol levels during the first and second months.
