Dymista nasal spray is used to relieve moderate to severe symptoms of allergies, for example: runny nose, post nasal drip, sneezing and itchy or blocked nose. This spray contains a combination of two active ingredients, Fluticasone Propionate 50 microgram, a low dose corticosteroid, and Azelastine hydrochloride 137 microgram, an antihistamine. These ingredients work really well together to provide quick and effective relief from the allergy symptoms.
