The FDA has approved the first-ever nasal spray equivalent of an Epi-pen. This intra-nasal epinephrine, called “Neffy“, has several advantages over traditional interventions for allergen exposure. It’s small, easy to use, and perhaps most importantly, is not a needle-based delivery mechanism. Interestingly, it also has a shelf life of 30 months, whereas injectors need to be refilled every 12-18 months.
