Is Melatonin Safe with Semaglutide (Ozempic)?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Use melatonin with awareness of its potential to affect blood glucose regulation. Short-term low-dose use (0.5–3 mg) for sleep support is generally considered low risk, but inform your healthcare provider of melatonin use. Monitor for unexpected changes in fasting blood glucose, particularly if using higher doses long-term.
Why this interaction occurs
Melatonin receptors (MT1 and MT2) are expressed on pancreatic beta cells and influence insulin secretion. Evidence suggests melatonin can inhibit glucose-stimulated insulin secretion, potentially opposing semaglutide's mechanism in certain contexts. The clinical significance varies by individual, dose, and timing, and long-term effects on glycemic control with concurrent semaglutide therapy remain incompletely studied.

Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 73,568 reports mentioning Semaglutide (Ozempic). This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Semaglutide (Ozempic) + supplement combination on this page.
