Caution
What is happening. Both zolpidem and melatonin promote sleep through different mechanisms. Combined use may cause excessive sedation but is sometimes used clinically under medical supervision.
Mechanism. Zolpidem acts on GABA-A receptors. Melatonin acts on MT1/MT2 receptors. The different mechanisms produce additive sedation.
Recommendation. If using melatonin with zolpidem, use very low melatonin doses (0.5mg). Excessive sedation, dizziness, and morning grogginess can occur. Discuss with your prescriber.
