neffy 1 mg is the first and only needle-free epinephrine treatment approved for younger children
SAN DIEGO, March 05, 2025 (GLOBE NEWSWIRE) — ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and caregivers to better protect themselves from allergic reactions that could lead to anaphylaxis, announced today that the U.S. Food and Drug Administration (FDA) has approved neffy® 1 mg (epinephrine nasal spray) for the treatment of Type I Allergic Reactions, including anaphylaxis, in children who are aged 4 years and older and weigh 15 to < 30 kilograms (33 to < 66 lb.). This approval represents the first significant innovation in the delivery of epinephrine for this patient population in more than 35 years.
In the general population, approximately one in 13 children have severe food allergies, and more than 40 percent have experienced severe reactions.1 Despite the clear link between early epinephrine use and better outcomes, research shows that approximately 40 percent of patients delay treatment2, and 56 percent of caregivers fear using needle-based auto-injectors on their child3. neffy eliminates needles, delivering a precise epinephrine dose via a simple nasal spray, almost instantly, with no nasal hold time required.
“Today’s FDA approval of neffy 1 mg marks a major milestone towards our efforts to transform the management of severe allergic reactions,” says Richard Lowenthal, Co-Founder, President, and CEO of ARS Pharma. “Many children and caregivers fear needle-based auto-injectors, which can delay lifesaving treatment. neffy’s needle-free, easy-to-use design addresses this unmet need, offering families a long-awaited alternative. With nearly four out of 10 U.S. epinephrine prescriptions written for children under the age of 18—and nearly a third of those for children weighing 15 to 30 kilograms4 —we believe neffy 1 mg will improve access to a needle-free option for the treatment of severe allergies and reduce hesitation in treating this vulnerable group. It will also eliminate risks like accidental needle injuries to children or caregivers.”
The approval of neffy 1 mg is based on data from extensive clinical trials, including pharmacokinetic (PK) and pharmacodynamic (PD) responses in pediatric and adult subjects that were consistent with those of epinephrine injection products. Adverse events in pediatric trials were generally mild and transient. Human factor studies also show children as young as 10 can use neffy effectively by following instructions, and that even untrained individuals, such as babysitters or teachers, can effectively administer neffy. The device has a shelf-life of 24 months at room temperature and tolerance to temperature exposures up to 122°F (50°C) based on testing for up to 3 months. If accidentally frozen, neffy can be thawed without impact on the product quality and reliability.
“The availability of a needle-free epinephrine option for children is a breakthrough in the treatment of severe allergic reactions,” says Dr. David Fleischer, Section Head of Allergy & Immunology, and Professor of Pediatrics, at Children’s Hospital Colorado. “Many people wait to administer epinephrine until symptoms progress or take antihistamines as a first line of defense because they are afraid of injection. neffy’s small, user-friendly design addresses these challenges, empowering people to actually carry epinephrine and act quickly and confidently during an allergic emergency. This innovation will likely significantly improve health outcomes and enhance quality of life.”
ARS Pharma is committed to access and affordability, and neffy 1 mg is expected to be available in the U.S. by the end of May 2025. The neffyConnect program provides patients, caregivers, and healthcare professionals with information to guide their treatment journey, details about medication fulfillment services, financial support and navigating insurance requirements. Most commercially insured patients will pay no more than $25 for two single-use neffy devices through a co-pay savings program. The co-pay savings card can be accessed at neffy.com and downloaded to an Apple Wallet and provided to the pharmacy. If the product isn’t covered by insurance, the cash price of $199 for two doses is available through BlinkRx and coupon can be downloaded from GoodRx for use at local retail pharmacies. For certain uninsured or underinsured U.S. residents meeting eligibility criteria and exhausted all other options, the ARS Pharma Patient Assistance Program (PAP) will provide neffy at no cost.
Eligible schools participating in the neffyinSchools program can receive neffy 1 mg upon availability. For more information, and to register for neffyConnect, visit www.neffy.com.
The approval of neffy 1 mg follows FDA approval for neffy 2 mg on August 9, 2024 for children and adults weighing 30kg ( 66 lb.), and approval for EURneffy in the EU by the European Commission on August 22, 2024.
About 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.
INDICATION AND IMPORTANT SAFETY INFORMATION FOR neffy (epinephrine nasal spray)
INDICATION
neffy is indicated for emergency treatment of type I allergic reactions, including anaphylaxis, in adult and pediatric patients aged 4 years and older who weigh 33 lbs. or greater.
IMPORTANT SAFETY INFORMATION
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.
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.

About Type I Allergic Reactions Including Anaphylaxis
Type I allergic reactions are serious and potentially life-threatening events that can occur within minutes of exposure to an allergen and require immediate treatment with epinephrine, the only FDA-approved medication for these reactions. While epinephrine auto-injectors have been shown to be highly effective, there are well published limitations that result in many patients and caregivers delaying or not administering treatment in an emergency situation. These limitations include fear of the needle, lack of portability, needle-related safety concerns, lack of reliability, and complexity of the devices. There are approximately 40 million people in the United States who experience Type I Allergic reactions. Of this group, over the last three years, approximately 20 million people have been diagnosed and treated for severe Type I allergic reactions that may lead to anaphylaxis, but (in 2023, for example) only 3.2 million filled their active epinephrine auto-injector prescription, and of those, only half consistently carry their prescribed auto-injector. Even if patients or caregivers carry an auto-injector, more than half either delay or do not administer the device when needed in an emergency.
