Holiday preparations often begin with a grocery list and a head count. For families managing food allergies, there is another conversation worth having before everyone gathers: Is our emergency plan ready, and does everyone know how to follow it?

Epinephrine nasal spray gives eligible patients an option that does not require an injection. Known by the brand name neffy, this prescription medication is used for allergic emergencies, including anaphylaxis.

For Corpus Christi families, understanding this option starts with a conversation about who can use it, how it compares with auto-injectors, and what belongs in an emergency action plan.

What Is Epinephrine Nasal Spray?

Neffy delivers medication through the lining of the nose. The FDA approved it in August 2024 as the first epinephrine product for anaphylaxis that is not administered by injection.

Its arrival addressed an unmet need: some patients hesitate to use emergency medication because they fear needles. A nasal spray may help reduce that barrier.

The approval drew on studies comparing epinephrine concentrations and effects on blood pressure and heart rate with approved epinephrine injection products. Researchers observed comparable blood concentrations and similar increases in those measures. That evidence supported approval; it does not mean every device works identically for every person.

This medication serves a different purpose from the sprays people use for everyday nasal congestion. It belongs in an emergency treatment plan for serious allergic reactions.

Who Can Use Neffy?

The March 2026 prescribing information covers adult and pediatric patients weighing at least 15 kilograms, or approximately 33 pounds. Dosing depends on weight:

• 15 kilograms to less than 30 kilograms: one spray containing 1 mg.

• 30 kilograms or more: one spray containing 2 mg.

The current label does not specify a minimum age. A prescribing clinician determines whether this epinephrine nasal spray is appropriate for the patient.

If you remember hearing that children weighing less than 66 pounds could not use it, you may have encountered information from the original approval. This is a useful example of why families should review new treatment options with their allergist rather than rely on an older article or social post.

Nasal Spray or Auto-Injector?

Both approaches deliver the medication used to treat anaphylaxis. Injectable epinephrine remains an established option, while the nasal spray offers another route of administration.

The decision involves more than a preference about needles. Before changing prescriptions, discuss:

• Which device you and your caregivers feel prepared to use.

• Your medical history and any nasal conditions.

• Prescription coverage, availability, and refill arrangements.

• How the device will fit into school, work, travel, and household routines.

Ask your health care professional whether your plan should include an auto-injector, a nasal spray, or access to both. Keep your existing prescribed rescue medication available while discussing a change.

Everyone who might help should learn the instructions for the specific device you carry. Familiarity with one product does not automatically prepare someone to use another.

Recognizing an Allergic Emergency

Anaphylaxis is a potentially life-threatening reaction that can progress quickly. Foods, insect stings, and medications are among its possible triggers.

Warning signs can include trouble breathing, throat tightness, wheezing, faintness, or repetitive vomiting. Allergic reactions may affect multiple parts of the body, including the skin, where hives or swelling may appear. However, anaphylaxis can occur without skin symptoms.

If you suspect anaphylaxis, use your prescribed rescue medication promptly and call 911. Do not wait for a rash or for symptoms to become more severe.

An antihistamine does not replace this treatment. It cannot adequately address dangerous breathing problems or a serious drop in blood pressure. Your written action plan should explain when to act and when to seek emergency medical assistance.

How Is the Nasal Spray Used?

Learn the full Instructions for Use before an emergency. Key points include:

• Give the prescribed spray into one nostril.

• Do not prime or test the device.

• Hold the nozzle straight and avoid sniffing during or afterward.

• If symptoms fail to improve or symptoms worsen, use a new device for a second dose in the same nostril starting five minutes after the first dose.

• Keep two devices immediately available.

More than two sequential doses require direct medical supervision.

Review administration with your clinician or pharmacist, then make sure family members and caregivers understand the instructions. An emergency is a difficult time to discover that someone has never seen the device.

Emergency medical assistance may include close monitoring and further treatment. Symptoms can return after an initial improvement, which is another reason to follow your action plan and obtain emergency evaluation.

Nasal Conditions and Other Precautions

Certain nasal conditions, including nasal polyps, previous nasal surgery, or a history of nasal injury, may affect absorption. Your clinician may recommend another route.

Patients with heart disease or other coexisting conditions also need individualized precautions. These concerns should not delay prescribed rescue treatment during a life-threatening allergic emergency.

Reported side effects include nasal discomfort, throat irritation, headache, runny nose, sneezing, dizziness, nausea, and feeling jittery. Review potential effects and your medication list before an emergency occurs.

A useful appointment question is: “Given my health history, what should I carry, and what should the people around me know?”

Prepare Before Holiday Dinner

A new device is only one part of holiday preparation. The rest of the plan needs to work around the actual gathering: who is cooking, where food will be served, and who will be available to help.

Talk with the host before the holiday

Explain the specific food allergy and ask about recipes and ingredients. Packaged-food labels identify the nine major allergens, including sesame, but a homemade dish may arrive without that information. Read labels each time you shop and ask questions when ingredients are uncertain.

A conversation before dinner gives everyone more time to find answers than a question asked while plates are being passed.

Discuss shared utensils and preparation

Cross-contact happens when an allergen unintentionally reaches another food. Shared equipment and ineffective cleaning can contribute to it. Talk through serving utensils and preparation arrangements rather than relying only on a dish’s ingredient list.

Make the emergency plan easy to find

Choose a place for rescue medication that the responsible adults can access immediately. Tell them where it is and how to use it.

For children spending the holiday with relatives, review the plan with the adults who will supervise meals. Include emergency contact information and the steps to take if a reaction occurs.

Check supplies before traveling

Review expiration dates and refill needs early. Keep the product’s instructions with your supplies, and follow its storage directions during travel. Carry two neffy devices if that is your prescribed rescue option.

Review Your Food Allergy Plan in Corpus Christi

If you have questions about a previous reaction or whether your current plan still fits, an allergy visit can help.

At Corpus Christi Allergy Associates, evaluation begins with your history. When appropriate, allergy testing may include skin or blood testing, with results interpreted alongside your experiences. Some patients may need a medically supervised oral food challenge to clarify a diagnosis.

Bring your current prescriptions and action plan, along with questions about nasal spray and auto-injector options. This is also an opportunity to discuss other allergies or asthma care that may affect your overall management.
