Spring allergy season is officially here, with many of us around the country already suffering with sneezing, nasal congestion, runny nose and itchy eyes as a result of the tree pollen in the air. Fortunately, for those people who rely on over-the-counter medicines for the treatment of their allergies, Allegra becomes available over-the-counter (OTC) this week without a prescription. Allegra (fexofenadine) is the only truly non-sedating antihistamine available for the treatment of allergic rhinitis and chronic idiopathic urticaria. Claritin and Zyrtec, which are considered to be low-sedating antihistamines, have been available OTC for a few years, and are also reasonable treatments for allergies. Allegra products (with coupons available) are available in 12 and 24-hour dosing regimens, as well as with pseudoephedrine (as Allegra-D), and in children's dosing as tablets, oral-disintegrating tablets, and liquid for those as young as 2 years of age.
