TLDR Isotretinoin effectively treats severe acne but can cause various side effects, with the most serious being birth defects, requiring careful monitoring and contraception.

Isotretinoin is an effective treatment for severe acne but can cause adverse effects across multiple systems. Common side effects include mucocutaneous reactions like cheilitis and xerosis due to sebaceous gland suppression. Hepatic enzyme elevations and dyslipidemia are dose-dependent but reversible, requiring regular lab checks. Musculoskeletal, ocular, and neuropsychiatric effects are rare and mild, though psychiatric monitoring is advised for at-risk individuals. Gastrointestinal and endocrine issues, such as subclinical hypothyroidism, are reported but not strongly linked to isotretinoin. Hematologic and renal changes are minor and temporary. The most significant risk is teratogenicity, necessitating strict contraceptive measures. Overall, isotretinoin's side effects are manageable with personalized dosing and monitoring, and understanding these mechanisms is crucial for safe and effective treatment.
