Shorter antibiotic course for lyme rash put to the test

NCT ID NCT03966014

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compares two treatment plans for people with erythema migrans, the classic Lyme disease rash. One group takes amoxicillin for 10 days, another for 14 days, and a third group gets no treatment. The goal is to see if a shorter course works just as well at preventing later symptoms. About 200 adults with the rash are being enrolled.

Active substance
amoxicillin
What this could lead to
If it works, this could show that a shorter course of amoxicillin is just as effective as a longer one for treating early Lyme disease.
What could go wrong
This is a moderate-sized trial, and the results may not apply to people with more advanced Lyme disease or other health conditions. Some patients may still have lingering symptoms.
