Rosula is used to treat inflammatory skin conditions including acne vulgaris, rosacea, and seborrheic dermatitis. It may also be prescribed for other conditions as determined by your healthcare provider.
The exact mechanism is not fully specified, but the combination of sulfacetamide sodium (an antibacterial agent) and sulfur (a keratolytic agent) works together to reduce bacteria on the skin surface and help shed dead skin cells, which can clog pores and contribute to breakouts.
Rosula is for external use only and should not come into contact with the eyes, mouth, or mucous membranes. Patients with sulfa allergies should avoid this medication. Common side effects may include skin irritation, dryness, or redness. Inform your doctor about all allergies and other medications before use.
