How do I use neffy?
Use neffy as soon as you notice symptoms of a serious allergic reaction, and follow these four steps:
1. REMOVE
Remove neffy from packaging. Pull open the packaging to remove the neffy nasal spray device.
2. HOLD
Hold device as shown. Hold the device with your thumb on the bottom of the plunger and a finger on either side of the nozzle.
- Do not pull or push on the plunger.
- Do not test or prime (pre-spray). Each device has only 1 spray.
3. INSERT
Insert the nozzle into a nostril until your fingers touch your nose. Keep the nozzle straight into the nose pointed toward your forehead.
- Do not point (angle) the nozzle to the nasal septum (wall between your 2 nostrils) or outer wall of the nose.
4. PRESS
Press plunger up firmly until it snaps up and sprays liquid into the nostril.
- Do not sniff during or after the dose is given. If any liquid drips out of the nose, you may need to give a second dose of neffy after checking for symptoms.
When using neffy:
- Each neffy nasal spray device has only 1 dose of medicine and is for single-use only.
- Always keep 2 neffy nasal spray devices with you.
- Use only in the nose. Avoid spraying in the eyes or mouth.
- Do not angle nozzle.
- Do not sniff during or after use.
- It is recommended that right‑handed dosing should be to the right nostril and left‑handed dosing should be to the left nostril.
- Patient can be in any position (e.g. sitting, standing, laying, reclining).
After using neffy:
- Get emergency medical help for further treatment of the allergic emergency (anaphylaxis), if needed, after using neffy.
- Check for symptoms after the first dose of neffy. If symptoms get worse or come back, give a second dose of neffy in the SAME nostril starting 5 minutes after the first dose.
Check your neffy periodically to be sure the expiration date has not passed. Replace your neffy before the expiration date has passed.

Is the epinephrine in neffy the same as in a needle-injector?
neffy delivers the same epinephrine you'd get from a needle-injector, but it comes in a nasal spray.
Does epinephrine from a nasal spray have the same effect in the body as a needle-injector?
The epinephrine in neffy affects the body like the epinephrine in a needle-injector, including blood pressure and heart rate.
How does the epinephrine in neffy get absorbed?
The epinephrine in neffy is designed to be rapidly absorbed into the nasal passage to reverse the reaction. neffy uses Intravail® technology, which temporarily loosens the spaces between the nasal cells to help epinephrine be absorbed into the body.

The nasal spray can get through stuffy noses, so don’t hesitate to use it in these conditions.
How should neffy be stored?
Store neffy at room temperature between 68°F to 77°F (20°C to 25°C). Storage of neffy at high temperatures up to 122°F (50° C) is allowed for a few days.
Can neffy still be used after being frozen?
Do not freeze. If neffy freezes, the device will not spray.
