Reduce Exposure to Food Allergies Make an Appointment Refer a Patient Ask a Question Reviewed by Bruce J. Lanser, MD, MPH (August 01, 2015) The best way to prevent an allergic reaction is to eliminate exposure to the specific type of food allergen. Know the different names of foods to which you are allergic. For example, lactate solids are a milk product. Read labels carefully to identify foods in packages. Ask about ingredients in food served at a restaurant or a friend's home. Educate caregivers about food allergies. Encourage children with food allergies not to eat food given to them by friends. Have a Food Allergy Action Plan. Precautions Use and understand allergy medications. Carry injectable epinephrine (e.g., EpiPen) and an oral antihistamine (e.g., Benadryl, preferably in the liquid or fast-melt preparation) as prescribed for emergencies. Learn more about your food allergies and how to avoid foods you are allergic to by talking with your doctor or a registered dietitian. Another reliable resource is the Food Allergy Research & Education website (foodallergy.org), which is regularly monitored and updated by allergists.
