What to expect from isotretinoin treatment for acne

Isotretinoin reduces oil production and changes the conditions that allow acne spots to develop. Your clinician chooses the dose and reviews your progress over time. Acne may look unsettled before it begins to improve, and improvement is usually gradual rather than immediate. Chapped lips, dry facial skin, dry eyes, or increased sensitivity to irritation can occur. Some people also notice muscle or joint discomfort. These effects should be discussed at follow-up rather than managed by changing the dose yourself.

Attend every scheduled review and complete any requested tests. Tell the prescriber about all medicines, supplements, allergies, liver problems, mood changes, and plans for pregnancy. Use a gentle cleanser, a plain moisturiser, lip balm, and sunscreen suited to sensitive skin. Avoid picking spots, waxing, harsh scrubs, and strong acne products unless your clinician approves them. Do not share capsules or use leftover medicine. Take the medicine exactly as directed and report troublesome dryness, headaches, vision changes, or mood symptoms promptly.

Contact your treatment team promptly for severe headache with visual symptoms, marked mood change, thoughts of self-harm, severe abdominal pain, yellowing of the skin or eyes, or a serious rash. Seek urgent help for breathing difficulty, facial swelling, or fainting. If pregnancy is possible or suspected while taking isotretinoin, stop and contact your prescriber urgently for specific advice.

Ask which moisturiser and sunscreen fit your skin, which medicines or supplements to avoid, what monitoring you need, and what to do if you miss a dose. Ask how acne scars or persistent marks will be handled after active acne is controlled.
