A:It sounds like you have already done allergy testing, my best advice to you is good old fashioned Benedryl. The store brand works just as well, it is one of the safest OTC drugs on the market. It may make him drowsy, so you'll probably want to give it to him before bed and before nap. You can safely give 3 doses a day. I have found that it works better than many prescription allergy meds. Check with your doctor, but this is what I would do. I hope this helps.
