What are levofloxacin tablets?
Levofloxacin tablets are a fluoroquinolone antibiotic medicine used in adults age 18 years or older to treat certain infections caused by certain germs called bacteria. These bacterial infections include:
• nosocomial pneumonia • plague
• community acquired pneumonia • urinary tract infections, complicated and uncomplicated
• skin infections, complicated and uncomplicated • acute kidney infection (pyelonephritis)
• chronic prostate infection • acute sinus infection
• inhalation anthrax germs • acute worsening or chronic bronchitis
Studies of levofloxacin tablets for use in the treatment of plague and anthrax were done in animals only, because plague and anthrax could not be studied in people.
Levofloxacin tablets should not be used in people with uncomplicated urinary tract infections, acute bacterial exacerbation of chronic bronchitis, or acute bacterial sinusitis if there are other treatment options available.
Levofloxacin is also used to treat children who weigh at least 66 pounds (or at least 30 kilograms) and may have breathed in anthrax germs, have plague, or been exposed to plague germs.
