Zadine Syrup

Unfortunately Zadine Syrup is no longer available.

Zadine Syrup is a non-drowsy medication used to treat those allergic conditions exacerbated by the chemical histamine. In certain conditions, histamine is released from mast cells in the body in response to the presence of allergens. This is because the immune system, having previously become sensitised to an allergen like pollen or dust mites, mistakenly interprets the intruder as a threat. This results in symptoms such as sneezing, red and watery eyes, itchy eyes and nose, and a running nose. These are all characteristic of an allergy like hayfever, which is referred to in medical circles as seasonal allergic rhinitis. Skin irritants such as stings and bites, as well as dermatological disorders like hives ( urticaria ), eczema and contact dermatitis, can all be treated using the antihistamine Zadine.
