 Levaquin medicineCommon usesThis medicine is a fluoroquinolone antibiotic used to treat bacterial infections (e.g., urinary tract infections, skin infections, or respiratory tract infections).

Other medicines besides levofloxacin which may affect the heart rhythm (qtc prolongation in the ekg) include dofetilide, pimozide, quinidine, sotalol, procainamide, and sparfloxacin among others.
