Diagnosing Peanut Allergy
Initial Steps in Diagnosis The journey to diagnosing a peanut allergy begins with a conversation about your symptoms and medical history, followed by a physical examination. Subsequent steps may include:
- Food Diary: Recording your dietary intake, symptoms, and medications as per your doctor’s advice.
- Elimination Diet: To pinpoint the cause of your symptoms, you might be asked to remove peanuts or other potential allergens from your diet temporarily, then reintroduce them one by one.
- Skin Test: A test where a small quantity of food is placed on your skin, which is then pricked; a raised bump indicates an allergy.
- Blood Test: This test measures the immune system’s response to foods by assessing the level of IgE antibodies in your blood.
Combining these methods helps ascertain whether you have a peanut allergy or if your symptoms stem from another cause, like food intolerance.
Treatment Approaches Avoiding peanuts is the primary treatment for peanut allergy, but ongoing research explores therapies like oral immunotherapy.
Oral Immunotherapy Explained This method involves gradually increasing the intake of peanut-containing foods for those with or at risk of peanut allergies. It aims to lessen the severity of allergic reactions, not to cure the allergy.
Palforzia: A New Therapeutic Option The FDA has approved Palforzia, an oral immunotherapy drug for children aged 4 to 17 with confirmed peanut allergies. It’s not suitable for individuals with certain conditions, such as uncontrolled asthma.
Preparedness for Allergic Reactions Avoiding peanuts is essential, but accidental exposure can happen. In such cases, an emergency epinephrine injection might be necessary.
Using an Epinephrine Autoinjector If prescribed:
- Carry it Always: Keep it accessible at all times, with extras stored in strategic locations.
- Check Expiry Dates: Ensure the medication is within its usage period.
- Have a Backup: Consider having a spare autoinjector.
- Learn to Use It: Familiarize yourself and educate those around you on its use.
- Recognize the Need: Understand when to administer the shot, erring on the side of caution if unsure.
Managing Life with a Peanut Allergy
Proactive Avoidance Strategies To prevent allergic reactions, awareness and vigilance in avoiding peanut exposure are key. Here’s how you can stay safe:
- Label Literacy: Never take for granted that a product is peanut-free. Always scrutinize food labels for mentions of peanuts or production in facilities that handle peanuts.
- Ingredient Vigilance: Ingredients can change; always recheck labels, even on familiar foods.
- Cross-Contamination Caution: Be wary of products from facilities that process peanuts, as even trace amounts can trigger reactions.
Navigating Social Dining Eating out or attending social events can be risky. If there’s any doubt about a dish’s contents, it’s safer to decline. Educate friends and family about the severity of peanut allergies to ensure they understand the risks involved.
Emergency Preparedness Consult your doctor about carrying emergency medication, such as epinephrine, in case of accidental exposure.

Safety Measures
- Medical Alert Accessories: Equip your child with a medical alert bracelet or necklace detailing their peanut allergy, which can be crucial during an emergency when they may not be able to communicate.
- Epinephrine Autoinjector: Always have an epinephrine autoinjector on hand for immediate response to severe allergic reactions.
Preparing for Medical Consultations Maximize the benefits of your medical appointments by being thoroughly prepared. Here’s how:
- Symptom Documentation: Be prepared to discuss your symptoms in detail, including the timeline and severity after peanut exposure.
- Medication Inventory: Compile a list of all medications, vitamins, or supplements you’re currently taking.
- Support Person: If possible, bring a companion to help remember information and support you during the appointment.
- Questionnaire: Have a list of questions ready for your doctor, such as:
- Are my symptoms indicative of a peanut allergy?
- Could other factors be causing my symptoms?
- What diagnostic tests are necessary?
- What treatment options are available?
- Is there a need for specialist consultation?
- Are there non-brand alternatives to prescribed medications?
- Can you provide any informative materials or recommend reliable websites?

For parents of children with peanut allergies, consider asking:

Anticipating Your Doctor’s Inquiries Your doctor may ask questions such as:
- When did you first notice the allergic symptoms?
- How quickly do symptoms manifest after consuming peanuts?

- What is the severity of your symptoms?
- What seems to alleviate or exacerbate your symptoms?
Interim Measures If you suspect a peanut allergy, avoid peanuts until you can see your doctor. In case of a severe allergic reaction, seek immediate medical assistance.
