FDA Approves First-Ever Nasal Spray for Anaphylaxis Treatment: A Game Changer for Allergy Sufferers

In a groundbreaking move, the U.S. Food and Drug Administration (FDA) has approved neffy (epinephrine nasal spray), the first nasal spray designed for the emergency treatment of life-threatening allergic reactions, known as anaphylaxis. This new treatment option is approved for both adults and children weighing at least 30 kilograms (about 66 pounds), offering a needle-free alternative to traditional epinephrine injections.

A Revolutionary Advancement in Allergy Treatment

Anaphylaxis is a severe allergic reaction that can occur within minutes of exposure to allergens such as certain foods, medications, or insect stings. The condition is a medical emergency, with symptoms ranging from hives and swelling to difficulty breathing and loss of consciousness. Epinephrine has long been the go-to, life-saving treatment for anaphylaxis, but until now, it has only been available through injection—a method that some, especially children, may find intimidating or distressing.

Dr. Kelly Stone, MD, PhD, Associate Director of the Division of Pulmonology, Allergy, and Critical Care in the FDA’s Center for Drug Evaluation and Research, emphasized the significance of this approval: “Anaphylaxis is life-threatening, and some people, particularly children, may delay or avoid treatment due to fear of injections. The availability of epinephrine nasal spray may reduce barriers to rapid treatment, providing an important and accessible option for those at risk.”

How Neffy Works and What It Means for Patients

Neffy’s approval is backed by four clinical studies involving 175 healthy adults. These studies compared the blood concentrations of epinephrine in participants after administering neffy versus traditional epinephrine injections. The results showed that neffy delivers epinephrine in a manner comparable to injections, with similar increases in blood pressure and heart rate—critical responses needed to counteract anaphylaxis.

The nasal spray is a single-dose product administered into one nostril. If symptoms do not improve or worsen, a second dose can be administered using a new spray in the same nostril. Despite its ease of use, patients are still advised to seek emergency medical assistance after using neffy to ensure proper monitoring and further treatment if necessary.

Important Considerations and Side Effects

While neffy is a significant advancement in allergy treatment, it does come with certain warnings. Individuals with nasal conditions, such as nasal polyps or a history of nasal surgery, should consult their healthcare provider before using neffy, as these conditions might affect the absorption of the medication. Additionally, those with certain coexisting conditions or sulfite allergies should be cautious and discuss their options with a healthcare professional.

Common side effects reported with neffy include throat irritation, tingling in the nose, headache, nasal discomfort, and dizziness, among others. Despite these potential side effects, the benefits of having a non-injection-based emergency treatment for anaphylaxis could be life-changing for many.

Fast-Track Approval and What’s Next

Recognizing the urgent need for a needle-free epinephrine option, the FDA granted neffy Fast Track designation, expediting its review and approval process. This swift approval highlights the FDA’s commitment to addressing critical public health needs.

The approval of neffy by the FDA represents a major milestone in the treatment of anaphylaxis, offering a new, less intimidating option for patients. As more people gain access to this life-saving nasal spray, it’s expected to make a significant impact on how allergic emergencies are managed, especially for those who have previously hesitated to use inject-able treatments.
