What treatments are available for a food allergy?

Generally, there are two main ways of medication to treat a food allergy. Firstly, antihistamines are used to treat mild to moderate allergic reaction. Secondly, the use of adrenaline to treat severe allergic reactions like anaphylaxis. I have a mild allergy to certain seafood but I usually have my antihistamines on hand and I can eat them in moderation.

one of the first way to reduce and control the allergy is to immediately stop taking the foods that triggered the reaction. doctors may often prescribe an auto-injector which you need to keep with you at all times, for use in sudden emergencies. antihistamines are also often prescribed in case of mild allergies.

My son is allergic to eggs. So you can imagine how bad that is. He can't even touch eggs. I don't think there is a cute for it.

Based on my knowledge no cure. Most of the time it's genetic.
