What sort of antihistamine, and what dosages, do you know? I've tried loratadine and ebastine.I'd be curious if zinc would work better in the form of zinc acetate lozenges or an ionic zinc liquid, to maximize absorption in the nasopharynx. Going the digestive route may not lead to high enough concentrations where it's needed. Long haulers have also seen results with antihistamines, so that may be worth a try.
