Levaquin (generic name: levofloxacin) is an antibiotic used to treat various bacterial infections in adults.
Levofloxacin belongs to the
fluoroquinolone class of antibiotics, which work by inhibiting bacterial enzymes called DNA gyrase and topoisomerase IV. These enzymes are critical for bacterial DNA replication, repair, and transcription, so blocking them stops the bacteria from duplicating and spreading. Levaquin treats infections such as
pneumonia,
urinary tract infections (UTIs),
sinusitis,
chronic bronchitis, and
skin infections. It is also used to prevent or treat
anthrax exposure.
This medication can be used in cases where other antibiotics may not be suitable.
Other drugs, such as
Avelox and
Ciprodex, are oral antibacterial medications based on fluoroquinolones that can also be prescribed for bacterial infections. The choice of antibiotic depends on the type of infection, the patient’s medical history, and the bacteria’s sensitivity to the drug.

For respiratory tract infections, the typical dose is 500 mg or 750 mg once daily for 5 to 14 days. For urinary tract infections, the usual dose is 250 mg once daily for 3 days. Don’t chew or crush the tablet. It should be swallowed whole with a glass of water. When necessary, a tablet can be halved at the marked line if a half-dose is prescribed.
