The only way to prevent an allergic reaction is to avoid soy and soy proteins.
Medications, such as antihistamines, may reduce signs and symptoms of soy allergies. Taking an antihistamine after exposure to soy may control your reaction and help relieve discomfort. Over-the-counter antihistamines include: diphenhydramine (Benadryl, others), chlorpheniramine (Chlor-Trimeton, others), cetirizine (Zyrtec, others) and loratadine (Alavert, Claritin, others).
Despite your best efforts, you can ingest soy unknowingly. If you have a serious allergic reaction, you may need an emergency injection of epinephrine and a trip to the emergency room.
