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 critical allergic reactions. The drug was accredited this month by the FDA to be used in adults and older kids.
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 supply a less expensive, much less painful, and extra handy possibility than the EpiPen, specialists say, research haven’t but been executed 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 critical allergic reactions.
“We’re very enthusiastic about this improvement however we do have critical considerations,” says Dr. Robert Wooden, director of Johns Hopkins Kids’s Middle’s Division of Allergy, Immunology and Rheumatology, and a Johns Hopkins professor of pediatrics.
Anaphylaxis, also called anaphylactic shock, is a extreme, generally life-threatening allergic response that comes on rapidly with signs equivalent to shortness of breath, hives, a drop in blood stress and a lack of consciousness in response to triggers equivalent 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 obtainable to sufferers as an injection. Use of epinephrine for the remedy of extreme allergic reactions has been in needle-based type because the FDA accredited 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 obtainable in 2018.
Needle substitute
Neffy is the primary different to injectable epinephrine. In scientific trials, drugmaker ARS Prescription drugs discovered the nasal spray is protected and delivers the identical quantity of epinephrine to the bloodstream as an auto-injector. The FDA accredited the spray on Aug. 9 for the emergency remedy of allergic reactions together with anaphylaxis in adults and youngsters 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 Chook, a pediatric allergist at UT Southwestern and director of the Meals Allergy Middle at Kids’s Medical Middle in Dallas.
It could be simpler to tolerate for grownup sufferers who’re hesitant to self-inject and for fogeys who’re squeamish about injecting their children.
Neffy — which is concerning the dimension of half an iPhone and matches simply in a pants pocket — can also be handier to hold than an EpiPen, says Chook. That alone may enhance compliance and adherence to epinephrine use amongst individuals with harmful allergic reactions.
Because it stands, solely about 40% of the highest-risk sufferers really carry their auto-injectors, in accordance with a 2023 research, which surveyed adults and youngsters with extreme allergic reactions and their caregivers. Contributors 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 health care provider of osteopathic drugs in personal 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 faculties 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 accordance with San-Diego based mostly ARS, which developed neffy over the past 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 saved at room temperature or they degrade. And neffy is straightforward to make use of with none coaching required.
Neffy may be simpler to manage accurately, 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 an alternative 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 really 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 turn into blocked. Which 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 individuals with particular meals allergic reactions. All had allergic reactions, three of which have been critical, and everybody acquired the drug. The corporate says neffy introduced reduction 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 accredited medicine, which may take about six months. He says the corporate plans to make a two-pack of the spray obtainable for costs that may differ relying on an individual’s means however are usually corresponding to the price of auto-injectors.
The value 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 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 kids.
For now, docs say they could keep away from prescribing the brand new spray simply after it hits the market, partly as a result of they would wish to dedicate worker hours to getting on the telephone to press insurance coverage firms to cowl it identical to with any new treatment, says Kaufman.
As soon as neffy turns into obtainable — doubtless in late September, in accordance with Lowenthal — Wooden says he’s prepared to prescribe it to sufferers who ask for it, however he’ll counsel additionally they maintain an auto-injector useful simply in case.
Then, he says, he’ll look forward to stories to return 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 really may turn into a recreation changer. “I’d have faith in it then,” he says.
