Severe allergic reactions can happen anywhere, anytime — and every second counts. In this episode, we explore the exciting new development of adrenaline nasal spray (Neffy) as a potential needle-free treatment for anaphylaxis. Could this innovation improve how quickly lifesaving medication is delivered? Could it reduce hesitation, fear of injections, and treatment delays?

Join us as we break down:

• How adrenaline nasal spray works in the body
• Safety, ease of use, and real-world benefits
• Differences vs. traditional adrenaline auto-injectors (e.g., EpiPen)
• What this could mean for patients, carers, schools, and emergency responders
• The future of anaphylaxis management and allergy care

Whether you’re a clinician, parent, educator, or someone living with severe allergies, this episode helps you stay ahead of the latest advances in food allergy and anaphylaxis treatment — all in clear, accessible language.

You can listen now to discover how a simple nasal spray could become a lifesaving revolution in allergy emergencies.
