First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two antibiotics—doxycycline and azithromycin—in 208 children aged 3 to 17 with pneumonia caused by Mycoplasma pneumoniae. The goal is to see if doxycycline stops fever faster and is safe, especially regarding tooth color changes. Participants take the medicine by mouth for 7 to 14 days and have their temperature and teeth checked.
