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 authorised 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, known 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 carried out 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 allergy symptoms.
“We’re very enthusiastic about this growth however we do have severe 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, often known as anaphylactic shock, is a extreme, typically life-threatening allergic response that comes on shortly with signs reminiscent of shortness of breath, hives, a drop in blood stress and a lack of consciousness in response to triggers reminiscent of 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 accessible to sufferers as an injection. Use of epinephrine for the therapy of extreme allergic reactions has been in needle-based kind for the reason that FDA authorised 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 for the reason that Seventies. A generic model grew to become accessible in 2018.
Needle substitute
Neffy is the primary various 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 authorised the spray on Aug. 9 for the emergency therapy 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 Fowl, a pediatric allergist at UT Southwestern and director of the Meals Allergy Middle at Kids’s Medical Middle 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 in regards to the dimension of half an iPhone and matches simply in a pants pocket — can also be handier to hold than an EpiPen, says Fowl. That alone may 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, 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 might efficiently keep away from the issues they’re allergic to.
Dr. Karen Kaufman, a physician of osteopathic drugs 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 exchange 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 a substitute of 12 to 18 months for the EpiPen, based on 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 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 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 will 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 unintentionally 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.
Insurance coverage protection is one other unknown. Lowenthal says ARS is working with the massive insurance coverage corporations to get neffy on their lists of authorised 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 differ relying on an individual’s means however are usually similar 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 based on 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, medical doctors say they could keep away from prescribing the brand new spray simply after it hits the market, partly as a result of they would want to dedicate worker hours to getting on the cellphone to press insurance coverage corporations to cowl it identical to with any new treatment, says Kaufman.
As soon as neffy turns into accessible — doubtless 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 preserve an auto-injector useful simply in case.
Then, he says, he’ll await reviews 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 sport changer. “I might trust in it then,” he says.
