Adrenaline nasal spray shows promise as a needle-free alternative to EpiPens, with faster absorption and similar effects, but more real-world data is needed.
Adrenaline nasal sprays may be as effective as EpiPens for treating severe allergic reactions, with faster absorption and comparable effects on heart rate and blood pressure, according to a review of five international studies presented at a European medical conference.
The FDA approved the nasal spray Neffy in August 2024 for adults and children weighing at least 66 pounds, offering a needle-free option with longer shelf life and greater portability.
While promising, experts say more real-world data is needed before widespread adoption, as conference findings remain preliminary until peer-reviewed publication.
