(See also Overview of Antibiotics.)
Telithromycin belongs to a class of antibiotics called ketolides.
Because telithromycin can have serious side effects, doctors typically use it only if other antibiotics are unavailable or cannot be used.
Telithromycin works by preventing bacteria from producing proteins they need to grow and multiply.
Telithromycin is taken by mouth and can be taken with or without food.
Telithromycin is recommended only for the treatment of people over 18 years old. Telithromycin is not used with pimozide (an antipsychotic drug) because abnormal heart rhythms (arrhythmias) may occur.
