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 individuals having severe allergic reactions. The drug was accepted 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, known as neffy, has the potential to offer a less expensive, much less painful, and extra handy possibility than the EpiPen, specialists say, research haven’t but been accomplished 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 individuals with severe allergic reactions.
“We’re very enthusiastic about this improvement however we do have severe 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 referred to as anaphylactic shock, is a extreme, generally life-threatening allergic response that comes on shortly with signs comparable to shortness of breath, hives, a drop in blood strain and a lack of consciousness in response to triggers comparable 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 kind for the reason that FDA accepted 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 for the reason that Seventies. A generic model turned accessible in 2018.
Needle substitute
Neffy is the primary different to injectable epinephrine. In medical 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 do not like 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 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 fogeys who’re squeamish about injecting their children.
Neffy — which is in regards to the measurement of half an iPhone and matches simply in a pants pocket — can be handier to hold than an EpiPen, says Chook. That alone may improve 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, based on a 2023 research, which surveyed adults and children 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 drugs in non-public observe in Vienna, Va., and a fellow of the American Academy of Allergy, Bronchial asthma and Immunology, says she thinks neffy will quickly change 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, based on San-Diego primarily based ARS, which developed neffy during the last eight years. The corporate additionally says neffy will be left within the warmth and the chilly for months at a stretch, whereas EpiPens should be saved at room temperature or they degrade. And neffy is straightforward 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, based on 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. 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 by accident squirts the drugs 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 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 turn into blocked. Which 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 allergic reactions. 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 has similarities to what an epinephrine autoinjector does.
Insurance coverage protection is one other unknown. Lowenthal says ARS is working with the massive insurance coverage firms to get neffy on their lists of accepted medicine, which may take about six months. He says the corporate plans to make a two-pack of the spray accessible for costs that may range 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 value by 600%. On common retail costs for EpiPen vary from $650 to $750, with out insurance coverage based on 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 underneath the tongue and is in late-stage trials. ARS says it’s growing a nasal spray for smaller kids.
For now, docs say they might keep away from prescribing the brand new spray simply after it hits the market, partly as a result of they would wish 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 — possible in late September, based on 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 helpful simply in case.
Then, he says, he’ll look ahead to 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 really may turn into a sport changer. “I might trust in it then,” he says.
