Ciprofloxacin use in HIV/AIDS requires caution due to potential interactions with antiretrovirals like ritonavir, which can increase ciprofloxacin levels, possibly necessitating dosage adjustments.

Patients with HIV/AIDS on ciprofloxacin may need dose adjustments if also taking antiretrovirals that affect liver enzymes, such as protease inhibitors, due to increased ciprofloxacin plasma concentrations.

When prescribing ciprofloxacin to HIV/AIDS patients, monitor for QT prolongation especially if on antiretrovirals like ritonavir, which can raise ciprofloxacin levels, necessitating careful dose management.
