High-Dose Isotretinoin Evaluated for Acne Treatment, Relapse
the MPR take:
Isotretinoin is indicated for the treatment of severe recalcitrant nodular acne unresponsive to conventional therapy (eg, systemic antibiotics) but the ideal dosing regimen is unknown. In a study published in JAMA Dermatology, 116 patients with acne resistant to other treatments received isotretinoin at a cumulative dose of <220mg/kg or ≥220mg/kg for 12 months. Patients receiving the higher dose had a lower rate of acne relapse compared to the lower dose group (26.9 vs. 47.4%, respectively) with retinoid dermatitis being the only adverse effect more common in the high-dose group. The authors note that higher doses of isotretinoin could be effective for both acne treatment and reducing relapse rates.
