Cat bite antibiotics: could less be more?
NCT ID NCT05846399
First seen Nov 01, 2025 · Last updated Jun 22, 2026 · Updated 31 times
Summary
This study looks at whether taking antibiotics for just one day after a cat bite to the hand or forearm works as well as the usual five-day course, or even a placebo. About 72 adults who are bitten and seek care within 24 hours will be randomly assigned to one of three groups. The goal is to see if shorter treatment can prevent infections without increasing harm.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Amoxicillin/clavulanate (or alternatives ciprofloxacin and clindamycin)
What this could lead to
If successful, this could show that a shorter course of antibiotics or even no antibiotics is safe after a cat bite, reducing unnecessary medication and side effects.
What could go wrong
This is a small, early-phase trial with only 72 participants, so results may not apply to everyone. There is a risk that shorter treatment or placebo leads to more infections.
