An expanded indication for baloxavir marboxil (Xofluza) to include postexposure prevention of influenza for patients ages 12 years and older after contact with an individual who has the flu. The drug, previously available only in tablet form, is also now available as granules for mixing in water. It was originally approved in 2018 for treating uncomplicated flu in patients ages 12 years and older who have been symptomatic for no more than 48 hours. A randomized, placebo-controlled trial evaluated its safety and efficacy for postexposure flu prevention. Overall, 1% of participants who received the drug had infection, fever, and at least one respiratory symptom from day 1 to day 10, compared with 13% of those who received a placebo. The most common side effects include diarrhea, bronchitis, nausea, sinusitis, and headache. Hypersensitivity reactions, including anaphylaxis, can also occur. The drug should not be co-administered with dairy products; calcium-fortified beverages; or laxatives, antacids, or oral supplements containing calcium, iron, magnesium, selenium, aluminum, or zinc.

Marketing of a device intended for the temporary reduction of sleep disturbance related to nightmares. The device, called Nightware, is indicated for adults ages 22 years and older who have nightmare disorder or nightmares from post-traumatic stress disorder (PTSD). It is available by prescription only and is intended for home use. Using a smartwatch and a smartphone that are configured and logged into a software application and the Nightware server, the device provides gentle vibration through touch based on an analysis of heart rate and motion during sleep. It should be used in conjunction with prescribed medications for PTSD and other recommended therapies for PTSD-associated nightmares and nightmare disorder, according to relevant consensus guidelines, the FDA said.
