Sulfadimethoxine (Albon) is an antibiotic in the Sulfonamide family. It is primarily used in veterinary medicine, but it is approved for human use in several countries (eg. Russia).
Sulfadimethoxine is rarely used as an acne treatment. For the treatment of active acne symptoms, other oral Sulfonamide antibiotics (eg. Sulfamethoxazole) are far more commonly prescribed. Sulfadimethoxazole is primarily available in oral formulations.
Clinical research on this medication as an acne treatment is limited. But the research that does exist indicates that Sulfadimethoxine is a partially effective treatment for patients with moderate to severe acne vulgaris. However, this research also found that Tetracycline and Erythromycin were substantially more effective than Sulfadimethoxine.
