Epinephrine · EpiPen & generics
Epinephrine is the first-line emergency treatment for anaphylaxis, a severe allergic reaction that can be life-threatening. Use it at the first signs, then call 911. The EpiPen, Auvi-Q and neffy labels each recommend being prescribed two devices, because a second dose may be needed, starting 5 minutes after the first if symptoms don't improve. An estimated 10.8% of US adults have a food allergy, and about half of them have had a severe reaction. Our providers review your allergy history online and can prescribe an EpiPen, a generic auto-injector, Auvi-Q or neffy, dosed by weight, and send it to your pharmacy before you fly.

EpiPen, Auvi-Q & neffy labels
Know it before you need it
The dose is set by weight. The first minutes go the same way whichever device you carry: use it early, call for help, and keep the second one ready.
For 66 lb and up (30 kg and up):
Doses from each device's FDA prescribing information. Wandr prescribes for adults 18 and over; children's doses are shown for reference, and your child's own doctor prescribes those.
For a severe allergic reaction, after a known or suspected trigger or when severe symptoms come on suddenly: trouble breathing, a tight throat, vomiting, feeling faint. Hives or swelling aren't required. Don't wait to see if it passes.
Remove the safety cap or release first. Press the device firmly against the middle of the outer thigh, through clothing if needed, and hold for the time in your device's instructions (3 seconds for EpiPen, 2 for Auvi-Q). With neffy, one spray in one nostril.
Call 911 right away, even if you feel better. Symptoms can come back. Abroad, use the local number: 112 works across the European Union.
If symptoms don't improve, get worse or come back, use the second device, starting 5 minutes after the first. With neffy, use a new spray in the same nostril. That's why the labels recommend carrying two.

Airports and abroad
Yes. TSA allows epinephrine auto-injectors in carry-on and checked bags, and the carry-on is where they belong. The final call rests with the officer at the checkpoint, so declare them.

TSA allows epinephrine auto-injectors in carry-on bags. Tell the officer you have them; medically necessary liquids may be inspected separately. Don't rely on a checked bag: you can't reach it mid-flight.
Both devices go wherever you go: the beach, the restaurant, the day hike. Show your travel companions where they are and how to use them.
911 doesn't work everywhere. 112 works across the European Union; look up the number for every country on your trip before you land.
Heat, cold and expiry
Store at 68–77°F (20–25°C); short swings from 59–86°F are allowed. Keep it in its carrier tube, away from light. Don't refrigerate it. Check the window: replace it if the liquid is pink, brown or cloudy, or has particles.
Follow the storage range and case on your own device's label, which can differ by maker. Keep it in its case, away from light and heat, and check the window for discolored or cloudy liquid.
Store at 68–77°F (20–25°C); short swings from 59–86°F are allowed. Keep it in its outer case, away from light. Don't refrigerate or freeze it, and don't leave it in a glove box. Check the window: replace it if the liquid is pinkish, darker than slightly yellow or cloudy, or has particles.
Store at 68–77°F (20–25°C). It can be exposed to heat up to 122°F (50°C) for a few days. Keep it in its blister pack or carry case until you use it. Don't let it freeze: a frozen neffy won't spray until it has thawed at room temperature for 20 minutes. Replace it before the expiration date on the pack.
Check the date on every device before you pack. If one expires before you're home, renew before you leave rather than abroad. Never leave them in a hot car or beach bag.

Who it's for
Adult travelers (18 and over) with a known severe allergy to food, insect stings, medicines or latex who need a renewal before an expiry date, a second set for the trip, or a different device. Our providers review your history and decide whether epinephrine is right for you.
Epinephrine buys time in a severe reaction. It doesn't replace an allergist's diagnosis, testing, or the written action plan you and your allergist build. If you've never been evaluated, our providers may recommend you see an allergist too.

Questions, answered
Yes, when it's appropriate. A Wandr physician reviews your allergy history online, usually within 24 hours, and, if epinephrine is right for you, sends a prescription for two devices to your pharmacy. It works best for adults (18 and over) who already know they have a severe allergy and need a renewal, a spare set for travel, or a different device.
Yes. TSA allows epinephrine auto-injectors in both carry-on and checked bags, but keep them in your carry-on so they're within reach. Tell the officer at screening that you have them; medically necessary liquids may be inspected separately. The final decision rests with the TSA officer.
The EpiPen, Auvi-Q and neffy prescribing information each recommend that patients be prescribed, and always have immediate access to, two devices. If symptoms don't improve or get worse after the first dose, the labels say a second dose can be given starting 5 minutes after it. A reaction can also happen far from a pharmacy when you travel.
The dose depends on weight. 66 lb and up (30 kg and up): EpiPen 0.3 mg, Generic auto-injector 0.3 mg, Auvi-Q 0.3 mg, neffy nasal spray 2 mg. 33 to under 66 lb (15 to under 30 kg): EpiPen Jr 0.15 mg, Generic auto-injector 0.15 mg, Auvi-Q 0.15 mg, neffy nasal spray 1 mg. 16.5 to under 33 lb (7.5 to under 15 kg): Auvi-Q 0.1 mg. Wandr prescribes for adults 18 and over; children's doses are shown for reference, and a child's own doctor prescribes them.
All deliver epinephrine for a severe allergic reaction. EpiPen and generic auto-injectors come in the same doses, though the steps can differ by maker, and generics usually cost less. Auvi-Q talks you through the steps and has an infant dose. neffy is a needle-free nasal spray approved by the FDA in 2024. Insurance coverage often decides between them.
It depends on the device. EpiPen and EpiPen Jr: Store at 68–77°F (20–25°C); short swings from 59–86°F are allowed. Keep it in its carrier tube, away from light. Don't refrigerate it. Check the window: replace it if the liquid is pink, brown or cloudy, or has particles. Generic auto-injectors: Follow the storage range and case on your own device's label, which can differ by maker. Keep it in its case, away from light and heat, and check the window for discolored or cloudy liquid. Auvi-Q: Store at 68–77°F (20–25°C); short swings from 59–86°F are allowed. Keep it in its outer case, away from light. Don't refrigerate or freeze it, and don't leave it in a glove box. Check the window: replace it if the liquid is pinkish, darker than slightly yellow or cloudy, or has particles. neffy nasal spray: Store at 68–77°F (20–25°C). It can be exposed to heat up to 122°F (50°C) for a few days. Keep it in its blister pack or carry case until you use it. Don't let it freeze: a frozen neffy won't spray until it has thawed at room temperature for 20 minutes. Replace it before the expiration date on the pack. Check the date on every device before you pack. If one expires before you're home, renew before you leave rather than abroad. Never leave them in a hot car or beach bag.
Call 911 right away, even if you feel better, because symptoms can return. Abroad, call the local emergency number (112 across the European Union). If symptoms don't improve, get worse or come back, use the second device starting 5 minutes after the first.
No. Epinephrine is emergency treatment. It doesn't replace an allergist's diagnosis, testing or your written action plan. If you've never been evaluated for a severe allergy, our providers may recommend you see an allergist as well.
