Be careful: If the other antihistamine causes drowsiness like chlorpheniramine then watch out because Benadryl (diphenhydramine) can cause drowsiness and the two could be too much to handle. Benadryl (diphenhydramine) and Allegra would be better tolerated but the combo may cause a dry mouth and other mucus membranes.
