General information

Allegra is an antihistamine that reduces the effects of natural chemical histamine in the body. The active ingredient is fexofenadine. It is used to treat the symptoms of seasonal allergies (hay fever) in adults and children. Allegra is also used to treat skin itching and hives caused by a condition called chronic idiopathic urticaria.

Directions

Use Allegra exactly as prescribed by your doctor. Take it with a full glass of water on an empty stomach, at least 1 hour before or 2 hours after a meal. Do not use any other type of liquid. Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. Never take more of the medication than your doctor has prescribed. For seasonal allergies the recommended dose for adults and children 12 years or older is 60 mg twice daily or 180 mg once daily. Children 6-11 years of age should be given 30 mg twice daily. For chronic urticaria, adults and children 12 years or older should use 60 mg twice daily, and children 6-11 years of age should use 30 mg twice daily.
