What is ciprofloxacin?


Ciprofloxacin is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of several infections caused by designated, susceptible bacteria, for example, certain urinary tract infections, lower respiratory tract infections, and skin infections.

Some bacterial infections are opportunistic infections (OIs) of HIV. An OI is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as people with HIV—than in people with healthy immune systems.

To learn more about OIs, read the HIVinfo What is an Opportunistic Infection? fact sheet.
