Ketek, also known as telithromycin, is an antibiotic manufactured by a French company, Sanofi-Aventis to treat pneumonia, bacterial bronchitis, and sinusitis. The Food and Drug Administration refused to approve Ketek in 2001 and 2003 because safer and cheaper alternatives were available. In April 2004, Ketek received FDA approval. Ketek has since been prescribed to more than 3.5 million people in the United States.

Ketek’s Approved Uses

The FDA approved the Ketek antibiotic to treat pneumonia, bacterial bronchitis, and sinusitis. In February 2007, the FDA restricted Ketek use to community acquired pneumonia (pneumonia acquired from outside a hospital) and withdrew its approval for bronchitis and sinusitis. This restriction was implemented after the Ketek antibiotic was linked to several severe side effects.

How does Ketek Antibiotic Work?

Ketek treats bacterial infections in the lungs and respiratory tract. The Ketek antibiotic contains the active ingredient telithromycin, an antibiotic used to treat bacterial infections. The Ketek antibiotic prevents bacteria from reproducing and controls the infection from spreading. The body’s immune system can then kill the remaining bacteria.

Who Should not Take Ketek?

The Ketek antibiotic should not be used by patients with the following medical conditions:

  • Heart problems

  • Prior liver problems
  • Severe kidney disease
