What Natlinez is and what it is used for

Linezolid is an antibiotic of the oxazolidinones group that works by stopping the growth of certain
bacteria (germs) that cause infections. It is used to treat pneumonia and some infections in the skin or
under the skin. Your doctor will have decided if this medicinal product is suitable to treat your infection.
