Food allergies can be a significant concern, impacting daily life. While there’s no one-size-fits-all cure, understanding what to take for food allergies, both for diagnosis and management, is crucial. This guide will explore the available options and what to expect.
Diagnosing Food Allergies
Diagnosing a food allergy is a process that involves considering several factors. There isn’t a single definitive test, so healthcare professionals rely on a combination of methods to confirm or rule out a food allergy.
Key Factors in Diagnosis
- Symptom History: A detailed account of your or your child’s symptoms is essential. This includes identifying which foods and how much of them seem to trigger reactions.
- Family History: Sharing information about family members with allergies (of any kind) can provide valuable insights.
- Physical Examination: A thorough examination can help identify or rule out other potential medical conditions.
Diagnostic Tests
-
Skin Prick Test: This test involves placing a small amount of the suspected food allergen on the skin (usually the forearm or back) and then pricking the skin to allow the substance to penetrate. A raised bump or reaction indicates a possible allergy. However, a positive result alone doesn’t confirm a food allergy.

-
Blood Test (IgE Test): This test measures the immune system’s response to specific foods by detecting the presence of immunoglobulin E (IgE) antibodies. A blood sample is sent to a lab to identify potential food allergens.
-
Elimination Diet: This involves removing suspected foods from your diet for one to two weeks and then reintroducing them one at a time. This process helps to identify specific foods that trigger symptoms. However, it doesn’t differentiate between a true allergy and a food sensitivity, and it’s not safe for individuals with a history of severe reactions.

Oral Food Challenge: Conducted in a healthcare professional’s office, this test involves consuming small, increasing amounts of the suspected food allergen under medical supervision. This test is crucial for confirming or ruling out a food allergy in a controlled environment.
Treatment Options for Food Allergies
The cornerstone of managing food allergies is avoiding the culprit foods. However, accidental exposure can happen, necessitating treatment strategies.
Immediate Relief for Mild Reactions
-
Antihistamines: These medications, available both by prescription and over-the-counter, can help alleviate mild allergy symptoms such as itching and hives. They work best when taken shortly after exposure. Common options include diphenhydramine (Benadryl), cetirizine (Zyrtec), and loratadine (Claritin).
Emergency Treatment for Severe Reactions
-
Epinephrine Autoinjector (EpiPen, Adrenaclick): For severe allergic reactions (anaphylaxis), an epinephrine autoinjector is essential. It’s a pre-filled syringe that delivers a single dose of epinephrine when pressed against the thigh. It is crucial to seek immediate medical attention at the emergency room even after administering epinephrine.
If you are prescribed an epinephrine autoinjector:
- Proper Training: Understand how to use the autoinjector correctly. Ensure that family members and close contacts are also trained.
- Carry it Always: Keep the autoinjector with you at all times. Consider having an extra one at work or in your car.
- Check Expiration Dates: Regularly replace the epinephrine autoinjector before the expiration date. Expired medication may not be effective.
Emerging Treatments and Therapies
- Omalizumab (Xolair): This monoclonal antibody medication, recently approved by the FDA, helps reduce allergic reactions to multiple foods in certain adults and children (1 year and older). It’s administered via regular injections and doesn’t eliminate the risk of reactions entirely.
- Peanut (Arachis hypogaea) Allergen Powder-dnfp (Palforzia): Approved for children ages 4 to 17 with confirmed peanut allergies, this oral immunotherapy drug is not suitable for those with uncontrolled asthma or eosinophilic esophagitis.
- Oral Immunotherapy (OIT) and Sublingual Immunotherapy (SLIT): These treatments involve exposing individuals to small, gradually increasing doses of the food allergen, either by swallowing it (OIT) or placing it under the tongue (SLIT).
Lifestyle Adjustments and Home Remedies
-
Read Food Labels Carefully: Always check food labels to ensure they don’t contain any allergens. Ingredients can change, so don’t rely on previous knowledge.
-
When in Doubt, Avoid: At restaurants or social events, if you’re unsure about the ingredients, it’s best to avoid consuming the food.
-
Inform Caregivers: If your child has a food allergy, educate relatives, babysitters, teachers, and other caregivers about the allergy and emergency procedures.

Managing Stress and Seeking Support
Living with a food allergy can be stressful. Strategies for managing stress include:
- Connect with Others: Join support groups or online forums to share experiences and information. Organizations like Food Allergy Research & Education (FARE) offer resources and events.
- Educate Those Around You: Ensure that family, caregivers, and school staff understand the food allergy and necessary precautions.
- Address Bullying: Discuss food allergies with school personnel to minimize the risk of bullying due to dietary restrictions.
Preparing for a Doctor’s Appointment
Be prepared for your appointment by:
- Documenting Symptoms: Record all symptoms, including those that seem unrelated.
- Listing Medications: Prepare a list of all medications, vitamins, and supplements.
- Writing Questions: Create a list of questions to ask, prioritizing the most important ones.
By understanding the diagnostic process, treatment options, and lifestyle adjustments, you can effectively manage food allergies and minimize their impact on your life. Always consult with healthcare professionals for personalized advice and treatment plans.
