Substitute drugs and related medications
Other fluoroquinolones related to ciprofloxacin include levofloxacin, ofloxacin and moxifloxacin; norfloxacin is used less commonly in the UK. While they share some properties, each agent has distinct licensed uses and safety considerations.
Non-fluoroquinolone options frequently considered depending on the infection and likely organism include:
- For many lower urinary infections: nitrofurantoin, trimethoprim, pivmecillinam or fosfomycin
- For common respiratory infections: amoxicillin, doxycycline or clarithromycin
- For skin infections: flucloxacillin, doxycycline or clindamycin
Therapy choice should follow culture results when available and local or national guidelines to reduce resistance and minimize avoidable harms. Discuss options and risks in conjunction with your prescriber.
