Sulfasalazine for alopecia areata.

Sulfasalazine is used as a therapy for various autoimmune conditions, including psoriasis; its effectiveness is presumed to be the result of its immunomodulatory effects. We have treated patients with severe alopecia areata with sulfasalazine as part of our dermatology practice and have noticed cosmetically acceptable regrowth in 23% of patients in whom a response could be determined. In view of its good safety profile, sulfasalazine may be considered for systemic treatment of severe alopecia areata.
