The epinephrine in neffy is designed to be rapidly absorbed into the nasal passage to reverse the reaction.
neffy starts to work in under a minute, providing fast, dependable epinephrine.
HOW neffy WORKS
- neffy uses Intravail® technology, which temporarily loosens the spaces between the nasal cells to help epinephrine be absorbed into the body.
- The epinephrine in neffy affects the body like the epinephrine in a needle‑injector, including blood pressure and heart rate.
- The nasal spray can get through stuffy noses.
