Patient Education

Ciprofloxacin


Ciprofloxacin is used to treat or prevent certain infections caused by bacteria such as pneumonia; gonorrhea (a sexually transmitted disease); typhoid fever (a serious infection that is common in developing countries); infectious diarrhea (infections that cause severe diarrhea); and infections of the skin, bone, joint, abdomen (stomach area), and prostate (male reproductive gland), Ciprofloxacin is also used to treat or prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack) and inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack). Ciprofloxacin may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and sinus infections, or certain types of urinary tract infections if there are other treatment options. Ciprofloxacin extended-release (long-acting) tablets are used to treat kidney and urinary tract infections; however, some types of urinary tract infections should only be treated with ciprofloxacin extended release tablets if no other treatment options are available. Ciprofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections. Antibiotics such as ciprofloxacin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Ciprofloxacin injection is used to treat certain infections caused by bacteria such as pneumonia; and infections of the skin, bone, joint, abdomen (stomach area), urinary tract, and prostate (male reproductive gland). Ciprofloxacin injection is also used to treat patients who have fever and are at high risk for infection because they have very few white blood cells. Ciprofloxacin injection is also used to prevent or treat plague (a serious infection that may be spread on purpose as part of a bioterror attack) and inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack). Ciprofloxacin may also be used to treat bronchitis and sinus infections, but should not be used for these conditions if there are other treatment options available. Ciprofloxacin injection is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.
