Niacin has been used as therapy for tinnitus for years with variable success. Niacin is thought to provide smooth muscle relaxation and perhaps increased blood flow to tiny blood vessels supplying the inner ear. Patients often sustain a blush when taking niacin in effective doses. Forewarn patients of this effect because some can be frightened by the phenomenon. About half of all patients with tinnitus report successful treatment with niacin. Patients often report that niacin decreases the intensity or severity of tinnitus.
