When should i take allergy medicine allegra (fexofenadine)?

Without food: Fexofenadine (allegra) comes in 2 doses for adults, 60 mg. And 180 mg. The 60 mg dose is taken twice a day, every 12 hr. The 180 mg dose is taken once a day, usually in the morning and it is more effective than 60 mg, 2x/day. Fexofenadine should always be taken 1 hr. Before food because food, especially fatty food, interferes with fexofenadine absorption.
