Allegra (fexofenadine hydrochloride) is an antihistamine used to treat allergic symptoms of seasonal allergic rhinitis (sneezing, runny nose, itchy or watery eyes), and urticaria (hives). Allegra is available as a generic drug termed fexofenadine hydrochloride. Allegra is used in adults and children (2 years and older for allergies, 6 months and older for hives) for the control and reduction of the above symptoms. Some common side effects of Allegra include nausea, diarrhea, upset stomach, muscle or back discomfort or pain, sleepiness, headache, and menstrual cramps. Contact your doctor if you have less common side effects of Allegra including allergic reactions, fever, chills, body aches, cough, or other flu symptoms.

Allegra is available in several strengths and forms; as tablets in strengths of 30, 60 and 180 mg, as 30 mg fast orally disintegrating tablets (available in foil blister packs and labeled "ODT"; the drug should not be touched by skin as it may begin to dissolve and reduce the oral dose) and as an oral suspension of 30mg per 5 ml. The dosage is dependent on the age, weight and effectiveness of the drug; special care should be taken when prescribing this drug to infants and children to make sure the recommended dosage is given. Drugs like ketoconazole and erythromycin may markedly increase the availability of the drug in the body while fruit juices can reduce the concentration. Follow the recommendations of the prescribing doctor to avoid these interactions. There are no studies of Allegra in pregnant or lactating women; the use in the pediatric population is described above. Note that the Allegra ODT tablets (orally disintegrating tablets) contain 5.3 mg of phenylalanine and should not be used by individuals with phenylketonuria.
