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.

Probably: I depends on what type of illness it is. Most of the time antihistamines such as Allegra (fexofenadine) are safe. Best to ask your doctor if it is appropriate in your situation.
