Yeah it’s wild that they don’t really make it obvious that antihistamines works pretty much anywhere or any way for allergies.

I’m allergic to Benadryl which means if I ever I’m having an allergic reaction to something else I’m allergic to I can’t treat the hives with Benadryl, but Zyrtec, Allegra, Claritin, all are somewhat effective in treating it. But man cetirizine is definitely the best one.
