The FDA approved Neffy, the first nasal spray epinephrine for anaphylaxis, offering a needle-free alternative for those over 66 pounds. Comparable to injectable epinephrine, Neffy aims to reduce treatment barriers, especially for children. Priced at $710 for a two-pack, with lower co-pays and a 30-month shelf life, it's expected to be available in the US within eight weeks. ARS Pharmaceuticals anticipates significant uptake, similar to Narcan, and plans to seek approval for younger children.
