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 certain types of bacteria, for example, certain urinary tract infections, lower respiratory tract infections, and skin infections.

Some bacterial infections can be 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.

Ciprofloxacin may affect the way other medicines or products work, and other medicines or products may affect how ciprofloxacin works.
