Is phenylephrine an antihistamine?
no, if it just says phenylephrine as the active ingredient, it’s just a decongestant like pseudoephedrine but not as good. Try benadryl (or diphenhydramine, no combination products though), that’s an antihistamine. The best people to ask besides a doctor is a pharmacist. Just call or go to any pharmacy and they can make a suggestion for you.
