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 permitted 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 supply a less expensive, much less painful, and extra handy possibility than the EpiPen, specialists 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 issues about whether or not the drug is efficient sufficient to belief for individuals with critical allergy symptoms.
“We’re very enthusiastic about this improvement however we do have critical issues,” 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, often known as anaphylactic shock, is a extreme, typically life-threatening allergic response that comes on rapidly with signs corresponding to shortness of breath, hives, a drop in blood strain and a lack of consciousness in response to triggers corresponding 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 accessible to sufferers as an injection. Use of epinephrine for the remedy of extreme allergic reactions has been in needle-based type because the FDA permitted 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 accessible in 2018.
Needle substitute
Neffy is the primary different to injectable epinephrine. In scientific trials, drugmaker ARS Prescribed drugs discovered the nasal spray is secure and delivers the identical quantity of epinephrine to the bloodstream as an auto-injector. The FDA permitted 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 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 Hen, 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 youngsters.
Neffy — which is concerning the measurement of half an iPhone and matches simply in a pants pocket — can be handier to hold than an EpiPen, says Hen. That alone might enhance compliance and adherence to epinephrine use amongst individuals with harmful allergy symptoms.
Because it stands, solely about 40% of the highest-risk sufferers really carry their auto-injectors, in response to 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 physician of osteopathic medication 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 exchange 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 response to San-Diego primarily based ARS, which developed neffy over the past eight years. The corporate additionally says neffy may 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 simple to make use of with none coaching required.
Neffy is likely to be simpler to manage accurately, provides Richard Lowenthal, co-founder, president and CEO of ARS. Operator errors can occur with auto injectors, in response to 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 could trigger a stroke, coronary heart arrhythmia, or coronary heart assault. Against this, 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 by chance squirts the medication into them.
Untested issues
However neffy additionally raises issues 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 change into blocked. Which may cease absorption of the drug and let a critical allergic response proceed unabated, Wooden says.
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 permitted medication, which might take about six months. He says the corporate plans to make a two-pack of the spray accessible for costs that can fluctuate relying on an individual’s means however are typically 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 worth by 600%. On common retail costs for EpiPen vary from $650 to $750, with out insurance coverage in response to 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 creating a nasal spray for smaller youngsters.
For now, docs say they could keep away from prescribing the brand new spray simply after it hits the market, partially as a result of they would want to commit worker hours to getting on the cellphone to press insurance coverage firms to cowl it similar to with any new medicine, says Kaufman.
As soon as neffy turns into accessible — probably in late September, in response to Lowenthal — Wooden says he’s keen to prescribe it to sufferers who ask for it, however he’ll recommend additionally they hold an auto-injector useful simply in case.
Then, he says, he’ll watch for stories to come back 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 really might change into a sport changer. “I’d trust in it then,” he says.
