Zirtek is a once daily, non-drowsy treatment for hay fever, skin, dust and pet allergies, urticaria and hives containing the active ingredient cetirizine which gives 24 hour relief from symptoms.
When the body is exposed to an allergen, a chemical known as histamine is released, which, in hay fever sufferers, indirectly leads to the onset of allergic symptoms like congestion and watery eyes. Cetirizine, the active ingredient in Zirtek, directs its effects by blocking the action of histamine, which in turn prevents the onset of allergic symptoms like a stuffy or blocked nose and sneezing, giving relief for up to 24 hours. Adults and children over 12 can take one 10mg tablet daily whereas age 6 – 12 can take half a tablet (5mg) twice daily. Alternatively, an oral solution is available.
