A probably ground-breaking nose-spray model of the drug epinephrine will quickly hit the market — an alternative choice to auto-injectors like EpiPen for folks having critical allergic reactions. The drug was accepted this month by the FDA to be used in adults and older youngsters.
However some allergists say they’re not in a rush to prescribe it.
Though the brand new needle-less choice, known as neffy, has the potential to offer a less expensive, much less painful, and extra handy choice than the EpiPen, consultants say, research haven’t but been performed on people who find themselves within the throes of life-threatening allergic reactions, referred to as anaphylaxis. That raises considerations about whether or not the drug is efficient sufficient to belief for folks with critical allergy symptoms.
“We’re very enthusiastic about this growth however we do have critical considerations,” says Dr. Robert Wooden, director of Johns Hopkins Kids’s Heart’s Division of Allergy, Immunology and Rheumatology, and a Johns Hopkins professor of pediatrics.
Anaphylaxis, also called anaphylactic shock, is a extreme, typically life-threatening allergic response that comes on rapidly with signs akin to shortness of breath, hives, a drop in blood stress and a lack of consciousness in response to triggers akin to meals, insect bites or medicines that an individual is allergic to.
Epinephrine is the one life-saving remedy for anaphylaxis and has beforehand solely been out there to sufferers as an injection. Use of epinephrine for the remedy of extreme allergic reactions has been in needle-based kind because the FDA accepted it in 1939. EpiPen, which is probably the most well-known model of auto-injector that an individual can use on their very own, has been round because the Nineteen Seventies. A generic model grew to become out there in 2018.
Needle substitute
Neffy is the primary different to injectable epinephrine. In scientific trials, drugmaker ARS Prescription drugs discovered the nasal spray is secure and delivers the identical quantity of epinephrine to the bloodstream as an auto-injector. The FDA accepted the spray on Aug. 9 for the emergency remedy of allergic reactions together with anaphylaxis in adults and children who weigh greater than 66 kilos.
Neffy, made by ARS Prescription drugs, could also be simpler to tolerate for individuals who don’t love injections.

There are causes to be enthusiastic about an epinephrine nasal spray, says Dr. J. Andrew Fowl, a pediatric allergist at UT Southwestern and director of the Meals Allergy Heart at Kids’s Medical Heart in Dallas.
It might be simpler to tolerate for grownup sufferers who’re hesitant to self-inject and for folks who’re squeamish about injecting their children.
Neffy — which is concerning the measurement of half an iPhone and matches simply in a pants pocket — can also be handier to hold than an EpiPen, says Fowl. That alone might improve compliance and adherence to epinephrine use amongst folks with harmful allergy symptoms.
Because it stands, solely about 40% of the highest-risk sufferers truly carry their auto-injectors, in line with a 2023 research, which surveyed adults and children with extreme allergic reactions and their caregivers. Individuals listed inconvenience and forgetfulness as the highest causes they didn’t carry their EpiPens, together with a perception that they might efficiently keep away from the issues they’re allergic to.
Dr. Karen Kaufman, a physician of osteopathic drugs in personal observe in Vienna, Va., and a fellow of the American Academy of Allergy, Bronchial asthma and Immunology, says she thinks neffy will quickly substitute auto-injectors in public areas like colleges and airplanes as a result of the product is smaller and simpler to retailer.
Amongst its different potential advantages — Neffy lasts longer than autoinjectors, with a shelf lifetime of two years as an alternative of 12 to 18 months for the EpiPen, in line with San-Diego primarily based ARS, which developed neffy during the last eight years. The corporate additionally says neffy might be left within the warmth and the chilly for months at a stretch, whereas EpiPens have to be stored at room temperature or they degrade. And neffy is simple to make use of with none coaching required.
Neffy is likely to be simpler to manage appropriately, provides Richard Lowenthal, co-founder, president and CEO of ARS. Operator errors can occur with auto injectors, in line with Mylan, the corporate that makes the EpiPen. One harmful mistake is injecting epinephrine right into a blood vessel as an alternative of into muscle. This may trigger a stroke, coronary heart arrhythmia, or coronary heart assault. In contrast, there’s no hazard if there are operator errors with neffy, Lowenthal says, including that ARS discovered no hurt to the eyes if the person unintentionally squirts the medication into them.
Untested considerations
However neffy additionally raises considerations amongst prescribing physicians. One fear, Wooden says, is that it hasn’t been examined in folks truly present process anaphylactic reactions as a result of researchers can’t ethically set off a probably lethal allergic response after which give a affected person a placebo. When somebody is having a extreme allergic response, he says, the nasal cavity can change into blocked. That may cease absorption of the drug and let a critical allergic response proceed unabated, Wooden says.
ARS prescribed drugs did do a small open label research in Japan. They used meals to set off allergic reactions in 15 folks with particular meals allergy symptoms. All had allergic reactions, three of which had been critical, and everybody obtained the drug. The corporate says neffy introduced aid to every participant inside 5 minutes, which has similarities to what an epinephrine autoinjector does.
Insurance coverage protection is one other unknown. Lowenthal says ARS is working with the large insurance coverage firms to get neffy on their lists of accepted medicine, which might take about six months. He says the corporate plans to make a two-pack of the spray out there for costs that may range relying on an individual’s means however are usually akin to the price of auto-injectors.
The worth of the EpiPen has been controversial since Mylan acquired the rights to provide it within the U.S. in 2007 and elevated the value by 600%. On common retail costs for EpiPen vary from $650 to $750, with out insurance coverage in line with GoodRx. A generic model prices between $150 and $200.
Different options to epinephrine auto injectors are additionally within the works. Nasus Pharma of Tel Aviv-Yafo, Israel, is engaged on an epinephrine powder that goes within the nostril, and New Jersey-based Aquestive Therapeutics has an epinephrine-laced movie that goes below the tongue and is in late-stage trials. ARS says it’s growing a nasal spray for smaller youngsters.
For now, medical doctors say they might keep away from prescribing the brand new spray simply after it hits the market, partially as a result of they would want to dedicate worker hours to getting on the telephone to press insurance coverage firms to cowl it similar to with any new medicine, says Kaufman.
As soon as neffy turns into out there — doubtless in late September, in line with Lowenthal — Wooden says he’s keen to prescribe it to sufferers who ask for it, however he’ll recommend in addition they maintain an auto-injector helpful simply in case.
Then, he says, he’ll watch for reviews to come back in about how neffy performs. If the spray does in addition to auto injectors to cease harmful allergic reactions to meals, medicine or insect bites, then sure, Wooden says it truly might change into a sport changer. “I’d believe in it then,” he says.
