Question: What
Answers:
Allegra D contains a decongestant in addition to the antihistamine!. The decongestant wouldn't make a difference in a rash, only in your nose/sinuses!. It is the antihistamine that should be helping your rash and that is the same dose in both the regular Allegra and the Allegra D!.Www@Answer-Health@Com
D stands for decongestant, like if you have a stopped up nose, usually pseudophed or something similarWww@Answer-Health@Com
