Back-to-school means more than pencils and planners for families managing allergic reactions
As backpacks fill and routines ramp up, so does the need to be prepared, not just with school supplies, but in case of accidental allergen exposure.
Now, there’s a way to do that without a needle. Meet neffy® (epinephrine nasal spray).
What makes neffy different?
neffy is the only needle-free epinephrine nasal spray, no more injections! If an allergic reaction happens at school, practice, or on-the-go, neffy starts to work in under a minute, providing fast, trusted epinephrine that your child needs. neffy is designed to be easy to use, so teachers, coaches, and others can step in to help quickly and without hesitation—even if you’re not with your child.
neffy supports children who fear injections, others who may hesitate, and caregivers who know how critical timing can be.
neffy may cause side effects so it’s important to talk to a doctor about any medical conditions or medications to determine if neffy is the right option.

INDICATION AND IMPORTANT SAFETY INFORMATION
WHAT IS neffy?
neffy is a nasal spray used for emergency treatment of allergic reactions including anaphylaxis, in adults and children aged 4 years and older who weigh 33 lbs or greater.
IMPORTANT SAFETY INFORMATION
What is the most important information that I should know about neffy?
neffy contains epinephrine, a medicine used to treat allergic emergencies (anaphylaxis). Anaphylaxis can be life-threatening, can happen in minutes, and can be caused by stinging and biting insects, allergy injections, foods, medicines, exercise, or other unknown causes.
Always carry two neffy nasal sprays with you because you may not know when anaphylaxis may happen and because you may need a second dose of neffy if symptoms continue or come back. Each neffy contains a single dose of epinephrine. neffy is for use in the nose only.
Use neffy right away, as soon as you notice symptoms of an allergic reaction. If symptoms continue or get worse after the first dose of neffy, a second dose is needed. If needed, administer a second dose using a new neffy in the same nostril starting 5 minutes after the first dose. Get emergency medical help for further treatment of the allergic emergency (anaphylaxis), if needed after using neffy.
Tell your healthcare provider if you have underlying structural or anatomical nasal conditions, about all the medicines you take, and about all your medical conditions, especially if you have heart problems, kidney problems, low potassium in your blood, Parkinson’s disease, thyroid problems, high blood pressure, diabetes, are pregnant or plan to become pregnant, or plan to breastfeed.
Tell your healthcare provider if you take or use other nasal sprays or water pills (diuretics) or if you take medicines to treat depression, abnormal heart beats, Parkinson’s disease, heart disease, thyroid disease, medicines used in labor, and medicines to treat allergies. neffy and other medications may affect each other, causing side effects. neffy may affect the way other medicines work, and other medicines may affect how neffy works.
What are the side effects of neffy?
neffy may cause serious side effects. If you have certain medical conditions or take certain medicines, your condition may get worse, or you may have more or longer lasting side effects when you use neffy.
Common side effects of neffy include: nasal discomfort, headache, throat irritation, chest and nasal congestion, feeling overly excited, nervous or anxious, nose bleed, nose pain, sneezing, runny nose, dry nose or throat, tingling sensation, including in the nose, feeling tired, dizziness, nausea, and vomiting.
Tell your healthcare provider if you have any side effects that bother you or that do not go away after using neffy.
These are not all of the possible side effects of neffy. Call your healthcare provider for medical advice about side effects. To report side effects, contact ARS Pharmaceuticals Operations, Inc. at 1-877-MY-NEFFY (877-696-3339)or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
