Ciprofloxacin
A broad-spectrum fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV, preventing bacterial DNA replication. It is used for a wide range of infections including urinary tract infections, respiratory infections, typhoid fever, and anthrax prophylaxis. Tendon rupture, peripheral neuropathy, and prolongation of the QT interval are important safety concerns.

Ciprofloxacin and ondansetron both prolong the QT interval; combined use raises the risk of torsades de pointes and sudden cardiac death.
Ciprofloxacin and quetiapine both prolong the QT interval and ciprofloxacin also increases quetiapine exposure via CYP3A4 inhibition.
Ciprofloxacin can reduce levothyroxine absorption through complex formation and potential effects on gut motility and transport, risking under-replacement in hypothyroid patients on long courses.
Ciprofloxacin consistently enhances warfarin's anticoagulant effect, raising INR and increasing the risk of bleeding complications.
Both azithromycin and ciprofloxacin prolong the QT interval; concurrent or overlapping use significantly increases torsades de pointes risk.
