A doubtlessly ground-breaking nose-spray model of the drug epinephrine will quickly hit the market — a substitute for auto-injectors like EpiPen for individuals having severe allergic reactions. The drug was authorized 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 possibility, referred to as neffy, has the potential to offer a less expensive, much less painful, and extra handy possibility than the EpiPen, consultants say, research haven’t but been completed on people who find themselves within the throes of life-threatening allergic reactions, generally known as anaphylaxis. That raises considerations about whether or not the drug is efficient sufficient to belief for individuals with severe allergy symptoms.
“We’re very enthusiastic about this growth however we do have severe considerations,” says Dr. Robert Wooden, director of Johns Hopkins Youngsters’s Middle’s Division of Allergy, Immunology and Rheumatology, and a Johns Hopkins professor of pediatrics.
Anaphylaxis, often known as anaphylactic shock, is a extreme, typically life-threatening allergic response that comes on rapidly with signs similar to shortness of breath, hives, a drop in blood stress and a lack of consciousness in response to triggers similar to meals, insect bites or medicines that an individual is allergic to.
Epinephrine is the one life-saving therapy for anaphylaxis and has beforehand solely been out there to sufferers as an injection. Use of epinephrine for the therapy of extreme allergic reactions has been in needle-based type because the FDA authorized it in 1939. EpiPen, which is essentially the most well-known model of auto-injector that an individual can use on their very own, has been round because the Seventies. A generic model turned out there in 2018.
Needle substitute
Neffy is the primary different to injectable epinephrine. In medical trials, drugmaker ARS Prescribed drugs discovered the nasal spray is protected and delivers the identical quantity of epinephrine to the bloodstream as an auto-injector. The FDA authorized the spray on Aug. 9 for the emergency therapy of allergic reactions together with anaphylaxis in adults and youngsters who weigh greater than 66 kilos.
Neffy, made by ARS Prescribed 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 Chicken, a pediatric allergist at UT Southwestern and director of the Meals Allergy Middle at Youngsters’s Medical Middle in Dallas.
It might be simpler to tolerate for grownup sufferers who’re hesitant to self-inject and for fogeys who’re squeamish about injecting their youngsters.
Neffy — which is concerning the dimension of half an iPhone and suits simply in a pants pocket — can also be handier to hold than an EpiPen, says Chicken. That alone may improve compliance and adherence to epinephrine use amongst individuals with harmful allergy symptoms.
Because it stands, solely about 40% of the highest-risk sufferers truly carry their auto-injectors, in accordance with a 2023 research, which surveyed adults and youngsters with extreme allergic reactions and their caregivers. Members listed inconvenience and forgetfulness as the highest causes they didn’t carry their EpiPens, together with a perception that they may efficiently keep away from the issues they’re allergic to.
Dr. Karen Kaufman, a health care provider of osteopathic medication in non-public follow 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 a substitute of 12 to 18 months for the EpiPen, in accordance with San-Diego based mostly ARS, which developed neffy during the last eight years. The corporate additionally says neffy may be left within the warmth and the chilly for months at a stretch, whereas EpiPens should be stored at room temperature or they degrade. And neffy is straightforward to make use of with none coaching required.
Neffy may be simpler to manage appropriately, provides Richard Lowenthal, co-founder, president and CEO of ARS. Operator errors can occur with auto injectors, in accordance with Mylan, the corporate that makes the EpiPen. One harmful mistake is injecting epinephrine right into a blood vessel as a substitute of into muscle. This will 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 consumer 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 individuals truly present process anaphylactic reactions as a result of researchers can’t ethically set off a doubtlessly 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 grow to be blocked. That may cease absorption of the drug and let a severe 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 individuals with particular meals allergy symptoms. All had allergic reactions, three of which have been severe, and everybody acquired the drug. The corporate says neffy introduced reduction to every participant inside 5 minutes, which is analogous to what an epinephrine autoinjector does.
Insurance coverage protection is one other unknown. Lowenthal says ARS is working with the large insurance coverage corporations to get neffy on their lists of authorized medication, which may take about six months. He says the corporate plans to make a two-pack of the spray out there for costs that can differ relying on an individual’s means however are usually corresponding 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 accordance with GoodRx. A generic model prices between $150 and $200.
Different alternate 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 creating a nasal spray for smaller youngsters.
For now, docs 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 corporations to cowl it similar to with any new treatment, says Kaufman.
As soon as neffy turns into out there — seemingly in late September, in accordance with Lowenthal — Wooden says he’s keen to prescribe it to sufferers who ask for it, however he’ll counsel additionally they preserve an auto-injector helpful simply in case.
Then, he says, he’ll await experiences to return in about how neffy performs. If the spray does in addition to auto injectors to cease harmful allergic reactions to meals, medication or insect bites, then sure, Wooden says it truly may grow to be a sport changer. “I’d believe in it then,” he says.
