Title: Relapse of acne following isotretinoin treatment: a retrospective study of 405 patients. Author: Liu A, Yang DJ, Gerhardstein PC, Hsu S. Journal: J Drugs Dermatol; 2008 Oct; 7(10):963-6. PubMed ID: 19112761. Abstract: BACKGROUND: Isotretinoin is the most effective systemic treatment option for patients with nodulocystic acne or acne vulgaris who have failed a treatment with systemic antibiotics. METHODS: We conducted a retrospective study of 405 acne patients treated with isotretinoin to evaluate the incidence of recurrence after a course of at least 150 mg/kg of isotretinoin. RESULTS: Of the 405 patients evaluated, 94 (23.2%) experienced relapses severe enough for the patient to request further medical management. Of the 94 patients, 76 (80.9%) relapsed within the first 2 years following completion of a course of isotretinoin. LIMITATIONS: This was a retrospective study at a single practice site. CONCLUSION: Almost one-fifth of patients have a recurrence of acne within the first 2 years. Patients should be made aware of this information, as it will contribute to the development of accurate and appropriate expectations of therapy.[Abstract] [Full Text] [Related] [New Search]
