1. What Fortum is and what it is used for

Fortum is an antibiotic used in adults and

children (including newborn babies). It works by

killing bacteria that cause infections. It belongs to

a group of medicines called cephalosporins.

Fortum is used to treat severe bacterial

infections of:

  • the lungs or chest
  • the lungs and bronchi in patients suffering

    from cystic fibrosis

  • the brain (meningitis)
  • the ear
  • the urinary tract
  • the skin and soft tissues
  • the abdomen and abdominal wall (peritonitis)
  • the bones and joints.

Fortum can also be used:

  • to prevent infections during prostate surgery

    in men

  • to treat patients with low white blood cell

    counts (neutropenia) who have a fever due to

    a bacterial infection.

    • If you are pregnant, think you might be

      pregnant or are planning to become pregnant
