Telithromycin

Telithromycin (Ketek) is an antibiotic in the Macrolide family. It is primarily used to treat certain types of bacterial respiratory infections.

Telithromycin is rarely used as a treatment for acne symptoms. There have been some safety concerns about the effect that this antibiotic has on the liver. The use of this medication in the United States was curtailed in 2007, and it is not widely used and may not be available in all countries.
