FDA approves first nasal spray to treat dangerous allergic reactions

U.S. health officials approved a nasal spray to treat severe allergic reactions, the first needle-free alternative to shots like EpiPen. The Food and Drug Administration (FDA) said it approved the spray from drugmaker ARS Pharmaceuticals Inc. as an emergency treatment for adults and older children experiencing life-threatening allergic reactions known as anaphylaxis. Anaphylaxis occurs when the body's immune system develops a sudden, unexpected reaction to a foreign substance, such as food, insect stings or medications. Common symptoms include hives, swelling, itching, vomiting and difficulty breathing. The device, marketed as Neffy, could upend treatment for the 33 million to 45 million Americans with severe allergies to food and other triggers. Anaphylaxis sends more than 30,000 people to emergency rooms and results in more than 2,000 hospitalizations and more than 230 deaths in the U.S. each year. Of the 6 million prescriptions written for auto-injectors each year, more than 40% are never filled, Dr. Thomas Casale, an allergist at the University of South Florida, told an FDA advisory panel last year. Even when they are available to caregivers, many auto-injectors are used incorrectly, he said. "There's a real unmet medical need for a large portion of the population," he said. Neffy is intended for people who weigh at least 66 pounds. It is given in a single dose sprayed into one nostril. A second dose can be given if the person's symptoms don't improve. The new treatment could be life-changing for people with severe food allergies, said Dr. Kelly Cleary, a pediatrician and director at the Food Allergy Research & Education, a nonprofit advocacy group. Requiring an injection in an emergency is as scary to some children as the allergic reaction itself. Some parents have had to restrain thrashing children to inject them, sometimes causing cuts that require stitches. About 3,500 caregivers a year are injured when they accidentally inject themselves in the hands, ARS said. Neffy is designed to be easy to carry and easy to use, especially for children, said Richard Lowenthal, president and chief executive of San Diego-based ARS. "We don't want fear. There's no needle, there's no pain with this product," he said. "It's basically like spraying saline into your nose." This article was provided by The Associated Press.
