I'm having an exercise induced asthma attack and don't have my inhaler. I took Allegra (fexofenadine) this morning but would taking another help?

Not likely. EIA is a result of muscular spasm of the alveoli of the lungs. An antihistamine, such as Allegra, (fexofenadine) will not relieve this. You need an inhaler to control this. In a pinch, caffeine (coffee,tea,chocolate) may help.
