Razene is used to treat hayfever and other allergic conditions. It is fast-acting, usually within 20 minutes and non-sedating. Its effects last for 24 hours, so you only need to take it once a day. Razene tablets are used for the relief of the symptoms associated with allergic rhinitis (hay fever), such as sneezing, runny or itchy nose, and burning or itchy eyes, and the symptoms associated with a skin condition called urticaria. The symptoms of urticaria include itching, redness and lumps on the skin called hives. Razene is also used for the relief of the symptoms associated with insect bites and allergic conjunctivitis.
