Oseltamivir (Tamiflu)
Oseltamivir phosphate · タミフル
Japan prescribes influenza antivirals far more readily than most countries: Tamiflu, the single-dose Xofluza (baloxavir, developed in Japan), inhaled Inavir and IV Rapiacta are all common. A clinic visit with a 15-minute rapid test is the standard route, and treatment is started the same day.
