Plague treatment showdown: ciprofloxacin vs doxycycline

NCT ID NCT01243437

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether the antibiotic ciprofloxacin works as well as doxycycline for treating plague, a serious bacterial infection. Only 5 people in Uganda took part, and they were randomly assigned to one of the two drugs. The goal was to see if ciprofloxacin could be a good alternative treatment, especially in places where other options are limited.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ciprofloxacin and doxycycline
What this could lead to
If ciprofloxacin works as well as doxycycline, it could provide another treatment option for plague, especially in areas where doxycycline is hard to get or can't be used.
What could go wrong
This is a very small study (only 5 people) and early-stage (Phase 2), so results may not apply broadly. Ciprofloxacin's effectiveness against plague in humans is still not well proven.
