Dosing
Providers generally recommend applying a thin film of sodium sulfacetamide lotion to the affected area. It is usually recommended that you apply the lotion at the same time each day and complete the full course of prescribed therapy, even if skin conditions improve. Stopping usage before your prescribed course is complete can cause infection recurrence and treatment resistance.

Uses
FDA-Approved Uses
Sodium sulfacetamide is FDA-approved to treat acne and seborrheic dermatitis.
Off-Label Uses
You may see sodium sulfacetamide prescribed for uses that are not “FDA-approved.” This is a common and legal practice called “off-label” prescribing, where a doctor uses their clinical judgment to prescribe a drug for a different (but well-researched) purpose.’
In this way, doctors may incorporate sodium sulfacetamide into broader skincare regimens for people with inflammatory skin conditions.
