What is isotretinoin used for?

Isotretinoin is a retinoid related to vitamin A. It reduces the activity of oil glands, lowers sebum production, helps prevent blocked pores, and calms acne-related inflammation. Because it affects several acne pathways, a dermatologist may consider it when other treatments have not controlled deep, widespread, or scarring acne. It is taken by mouth and needs an individual prescription and monitoring plan.

Dry lips and dry skin are common treatment effects. Other symptoms can occur, and mood changes, severe headache with visual symptoms, marked abdominal pain, or unusual muscle weakness should be reported promptly.

Before starting, tell the dermatologist about pregnancy or plans for pregnancy, breastfeeding, medicines, supplements, liver problems, mood history, and previous acne treatments. Follow the prescribed dose and monitoring schedule; do not share capsules or change the dose yourself. Use gentle cleanser, moisturiser, and lip balm, and protect sensitive skin from sunlight. Avoid waxing, irritating procedures, and vitamin A supplements unless the prescriber gives specific advice.

Contact the prescribing team urgently if pregnancy occurs or might have occurred during treatment. Seek prompt medical advice for severe headache or visual change, intense abdominal pain, yellowing of the skin, serious rash, marked mood change, or thoughts of self-harm. Sudden severe muscle pain or weakness also warrants assessment.

Ask why isotretinoin is suitable for your acne, which checks are needed, how to manage dryness, which products and procedures to avoid, and what symptoms require a same-day call. Clarify pregnancy-prevention requirements and follow-up before taking the first capsule.
