Fluoroquinolones: how to use (but not overuse) these antibiotics.
The fluoroquinolone antibiotics are relatively new agents with long serum half lives, a high degree of bioavailability, and a broad spectrum of activity against many gram-negative and some gram-positive organisms. They are useful in a range of clinical settings but should not be considered as first-line treatment of many infections. Specific indications include chronic osteomyelitis caused by multiple-resistant gram-negative bacilli, chronic bacterial prostatitis refractory to other oral antibiotics, complicated urinary tract infections, and empiric therapy of suspected bacterial GI infections. Quinolones may also be considered when patients are allergic to a conventional agent, when infections are caused by multiple-resistant gram-negative bacilli, or when the toxicity of an alternate therapy is greater.
