There is no cure for allergies, but there are several types of medications available -- both over-the-counter and prescription -- to help ease annoying symptoms like congestion and runny nose. These allergy drugs include antihistamines, decongestants, combination drugs, corticosteroids, and others. Zyrtec (Cetirizine) is used for preventing or treating symptoms of hay fever and other upper respiratory allergies such as stuffy nose, runny nose, sneezing, itching of the nose and throat, and itchy/ watery eyes. It is also used for preventing or treating chronic hives. It may also be used for other conditions as determined by your doctor.
When you are exposed to an allergen like- ragweed pollen, it triggers your immune system to go into action. Immune system cells known as "mast cells" release a substance called histamine, which attaches to receptors in blood vessels causing them to enlarge. Histamine also binds to other receptors causing redness, swelling, itching, and changes in secretions. By blocking histamine receptors, antihistamines prevent these symptoms.
