Summary

This study compares the effectiveness, safety, and long-term benefits of commonly used insomnia medications, including prescription drugs like zolpidem and trazodone, and over-the-counter options like melatonin and diphenhydramine. Researchers will enroll 1,200 adults with chronic insomnia to see which treatments work best after one month and up to six months. The goal is to provide clear guidance on the best choices for managing insomnia.
