Allegra and Zyrtec are drugs that are usually recommended for the treatment of allergic reactions. These medicines are available in prescription and over-the-counter forms. The first thing that needs to be established is that these two drugs are used for the treatment of basically the same kind of health conditions. However, the components of each medicine are different. For instance, the primary active ingredient in Zyrtec is Cetrizine and the active ingredient in Allegra, on the other hand, is Fexofenadine. Both medications are under a class of drugs known as antihistamines.
Antihistamines function by obstructing a substance known as histamine in the body. Histamine is believed to be the root cause of many allergic symptoms in human bodies. By obstructing this substance, symptoms of hay fever or seasonal allergies are prevented.
