Isotretinoin for Acne Under 18 in the UK: What Changed in April 2026?

In April 2026, NICE removed the rule that two independent health professionals had to approve isotretinoin — a prescription vitamin-A-based medicine for severe acne — for under-18s in the UK. A single consultant dermatologist can now start treatment. NICE says the April update aligns the acne guideline with the end of the regulatory requirement, described in the NICE update information. The underlying change took effect on 22 January 2026.

Why did the two-person rule end?

The 2023 system asked a second prescriber to check each under-18 initiation. An implementation review looked at how that worked in practice. It found the extra check added delay with very little disagreement. The October 2025 dermatology-services survey reported delays to under-18 access and minimal second-prescriber disagreement.

The MHRA Drug Safety Update says prescribers no longer need that second sign-off, in the MHRA Drug Safety Update on the January 2026 prescribing change. One responsible consultant now makes and records the decision. This does not lower the treatment threshold. It removes one administrative step. The clinical bar stays high.

Who can still get it under 18?

The affected group remains narrow. MHRA safety measures still in force reserve isotretinoin for severe nodular or conglobate acne, or acne at risk of lasting scars, described in the MHRA October 2023 safety measures. It applies only after an adequate course of systemic antibacterials plus topical treatment has failed.

Treatment must stay under consultant-dermatologist supervision. A GP cannot start it alone. Referral to dermatology remains the route. Families can check eligibility before the appointment:.

severe, lumpy or joining-up spots, or early scarring
prior systemic antibacterial plus topical therapy for an adequate course
referral to, and supervision by, a consultant dermatologist

What replaces the second signature?

The replacement is a clearer consent process for every patient. MHRA requires a streamlined two-page Acknowledgement of Risk form. It confirms the patient understands the indication, has seen awareness material, and knows they can seek a second opinion. Clinics must show the British Association of Dermatologists patient video.

The patient signs that they understand why isotretinoin is proposed. Parents and teens sign together where appropriate. MHRA also requires services to join the 2026 clinical audit. NHS and private clinics could move to single-prescriber initiation immediately, with time to change local pathways. The revised form is mandatory from the switch.

What risks still need careful counselling?

Isotretinoin is not for prepubertal acne. MHRA and the Commission on Human Medicines do not recommend it under age 12 because efficacy and safety data are lacking. Pregnancy prevention remains central because of serious birth-defect risk. Mood, behaviour, and sexual-function effects also need direct discussion and follow-up.

Counselling and monitoring continue at each visit. The right to ask for a second opinion stays. A teen who feels unsure can request another dermatology view before signing. The form records that choice.

What should families do next?

Ask the GP for a dermatology referral if scarring acne persists despite combined treatment. Bring a list of past prescriptions, durations, and side effects. Ask what else was tried and why isotretinoin now fits.

At the dermatology visit, watch the full video and read the two-page form before signing. Ask about pregnancy testing, contraception, blood tests, mood checks, and follow-up timing. Book the monitoring visits before leaving clinic.
