Does anyone know of an antihistamine for a slight food allergy?

I think I have a slight allergy problem with bananas and it tends to make my mouth raw like when you eat something that burns your mouth. I’m ok if I have 1 or two bananas but I had several meals this weekend that included bananas in the dish and now my mouth is really sore and I have a headache.
I don’t remember if its allegra, benedryl, claritin, or singular that helps with food allergy reactions.
