Needle-Free Relief: New Nasal Spray Offers Lifeline for Anaphylaxis Sufferers in the UK

For millions facing the constant threat of severe allergic reactions, a new option has arrived. The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has approved EURneffy, a needle-free nasal spray delivering adrenaline for the emergency treatment of anaphylaxis. This isn’t just another epinephrine delivery system; it’s a potential game-changer, addressing long-standing concerns about accessibility, usability, and patient anxiety surrounding traditional auto-injectors.

Beyond the Auto-Injector: A New Era in Emergency Allergy Treatment

Anaphylaxis, a life-threatening allergic reaction, demands immediate adrenaline administration. Until now, that meant relying on auto-injectors – devices that, while effective, can be intimidating for both patients and bystanders. The fear of incorrect injection, accidental self-injury, and the physical force required to operate them have been significant barriers. EURneffy, manufactured by ALK-Abelló, bypasses these issues with a simple, single-activation spray delivered directly into the nostril.

The approval follows a streamlined process thanks to the MHRA’s new International Recognition Procedure, launched in January 2024. This pathway allows the UK to swiftly adopt approvals already granted by trusted regulatory bodies, like the European Union, where EURneffy received authorization in August 2023. This accelerated approval process signals a broader shift towards greater international collaboration in healthcare regulation.

Who Can Benefit from EURneffy?

The nasal spray is designed for adults and children weighing 30 kg (approximately 66 lbs) or more. It delivers a consistent 2mg dose of adrenaline, even in the presence of nasal congestion – a crucial advantage over some other delivery methods. It’s indicated for reactions triggered by common allergens like insect stings, foods, medications, and even exercise. However, it’s vital to remember that patients should always carry two doses, with a second dose administered after 10 minutes if symptoms persist, and seek immediate medical attention regardless of initial symptom resolution due to the risk of biphasic anaphylaxis.

Shelf Life and Stability: Addressing Practical Concerns

Beyond ease of use, EURneffy boasts practical advantages over traditional auto-injectors. ALK-Abelló highlights a 30-month shelf life and improved temperature stability. Auto-injectors are notoriously sensitive to temperature fluctuations, potentially rendering them ineffective if exposed to extreme heat or cold. This enhanced stability could be particularly beneficial for individuals who travel frequently or live in climates with significant temperature variations.

Clinical Evidence: How Does it Stack Up?

Data presented at the European Academy of Allergy and Clinical Immunology congress demonstrated that EURneffy delivers a pharmacological response comparable to intramuscular adrenaline auto-injectors. While ethical constraints prevent testing the spray on patients during an acute anaphylactic event, trials involving over 700 participants showed promising results. Real-world data further supports its effectiveness in acute situations. Importantly, clinical studies reported no serious adverse events, with the most common side effects – throat irritation, headache, nasal discomfort, and jitteriness – occurring primarily after a second dose (4mg total).

The Future of Anaphylaxis Management: Beyond Treatment

The approval of EURneffy isn’t just about a new treatment option; it’s a catalyst for broader innovation in anaphylaxis management. We can anticipate several key trends:

• Personalized Allergy Profiles: Advances in genetic testing and allergy diagnostics will allow for more precise identification of individual triggers and risk levels, enabling proactive management strategies.
• Smart Epinephrine Devices: Integration of technology – such as Bluetooth connectivity and GPS tracking – into epinephrine delivery devices could improve response times and provide valuable data for healthcare providers.
• Enhanced Patient Education: Increased awareness and education about anaphylaxis, including proper recognition of symptoms and appropriate use of emergency treatments, will be crucial.
• Focus on Prevention: Research into oral immunotherapy and other desensitization therapies holds promise for reducing the risk of allergic reactions in the first place.

The MHRA will continue to monitor EURneffy’s safety and effectiveness through the Yellow Card scheme, and healthcare professionals and patients are encouraged to report any suspected side effects. Further details, including the Patient Information Leaflet and Summary of Product Characteristics, will be available on the MHRA website within seven days.
