Demazin Syrup

Demazin Syrup combines a decongestant and antihistamine in one medication that provides relief from the symptoms of colds, hayfever and other allergies. These symptoms include a runny nose, sneezing, sinus and nasal congestion, congestion accompanying glue ear or Eustachian tube blockage, and watery, itchy eyes. Each 5ml of Demazin Syrup contains 1.25mg of Chlorpheniramine maleate and 2.5mg of Phenylephrine hydrochloride as the active ingredients. Chlorpheniramine maleate is an antihistamine that blocks the action of histamine released by the body while Phenylephrine hydrochloride works as a decongestant, reducing swelling and congestion. Demazin Syrup comes in Vanilla and Peach flavour and is available in a 200ml bottle with a child resistant cap.
