First seen Nov 01, 2025 · Last updated May 16, 2026 · Updated 29 times

Summary

This study tests whether a higher dose of the antibiotic cephalexin can better treat cellulitis, a common skin infection, in adults visiting the emergency room. About 446 participants will receive either high-dose or standard-dose oral antibiotics and be followed for a week. The goal is to see if the higher dose reduces treatment failure and the need for hospitalization.
