1. What Sivextro is and what it is used for
Sivextro is an antibiotic that contains the active substance tedizolid phosphate. It belongs to a group of medicines called “oxazolidinones”.
Sivextro is a tablet for adults, as well as adolescents and children weighing at least 35 kg with infections of the skin and tissues below the skin.
Sivextro works by stopping the growth of certain bacteria which can cause serious infections.
