Start a food diary: Though it is time-consuming, you may wish to start a food diary. Begin with simple foods (only!) to which you KNOW you don’t react. Then add a new food ever 3 or 4 days and watch for an allergic reaction. Note on paper or smart phone (there’s a food allergy app for this) no, mild, or bad reaction. This takes time and diligence, but you should be able to find out which foods to avoid. ...Read more

Can I give my 5 yr old an antihistamine before eating out for fear that might eat foods not allowed for him because he has allergies

Benadryl (diphenhydramine) or Epipen: Which antihistamine are you planning to give? And do you know what they're allergic too? Most times you only give antihistamines if you know your going to be exposed to an allergen. If you feel you must give one, do not give Benadryl (diphenhydramine) until age 6. The other problem with medicating children is that adults tend to give too much. My advice is to get a prescription for Epipen to use for emergencies... ...Read more
