Abstract
Isotretinoin is one of the most effective drugs for the treatment of all forms of acne vulgaris. It has been suspected of causing alterations in lipids and liver enzymes. The aim of this retrospective study was to determine the prevalence of laboratory changes among 371 patients with acne receiving isotretinoin therapy. Each patient's medical records were evaluated to determine baseline alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol, and triglycerides (TGs) compared to levels recorded at 2 later readings following initiation of treatment with oral isotretinoin. Results indicated that isotretinoin can be administered with minimal concern regarding changes in serum transaminase and lipid profiles. Nevertheless, physicians should be cautious when administering isotretinoin in patients with a history of abnormal findings.
