Hi can anyone tell me if antihistamines affect food allergy testing , its just that I am hoping to get molly, tested at some point next week, and wondered if the antihistamines affect the test. thanks eleanor

Would have thought it would, when peole are tested it is, I think, the histamine reaction that is used to assess what the allergy is. So if the antihistamine is blocking the reaction the test would not be helpful, that is just what I think I would ask your vet.
