Isotretinoin is used to treat acne. When taken during pregnancy it can cause birth defects and miscarriages.

The MHRA advises that patients of childbearing potential being treated with isotretinoin must be on a Pregnancy Prevention Programme with regular follow-ups and pregnancy testing. Each prescription for oral isotretinoin should be limited to a supply of up to 30 days’ treatment.

Following an incident in which a patient of childbearing potential appeared to have been issued a 4-month prescription of isotretinoin instead of the intended 4 weeks the Group developed a resource to share what happened, enabling others to learn from the incident and review their own practices.
