Furosemide, a loop diuretic, is used to increase urine output in patients with acute kidney injury (AKI). It remains uncertain whether the benefits of furosemide in AKI outweigh its potential harms. We investigated if furosemide influenced oxidative stress in 30 critically ill patients with AKI by measuring changes in F2-isoprostanes (F2-IsoPs), markers of in vivo oxidative stress, in plasma and urine following intravenous furosemide. Urine F2-IsoPs were higher in sepsis (p = 0.001) and increased in proportion to urine furosemide (p = 0.001). The furosemide-induced increase in urine F2-IsoPs differed depending on AKI severity (p
