Melatonin and Ketamine Therapy | Tovani Health

Natrol (Melatonin) (also: Nature Made Melatonin)Endogenous hormone / OTC sleep supplement

Verdict at Tovani Health

Compatible; the sedation overlap is mild and rarely matters.

Melatonin and ketamine have no clinically significant interaction. Melatonin is mildly sedating at typical 0.5-3 mg doses; the overlap with ketamine session sedation is small.

If you take Natrol regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.

How Natrol interacts with ketamine

Melatonin agonizes MT1 and MT2 receptors, signaling circadian sleep onset. No overlap with ketamine pharmacology.

What we do at intake

Take at bedtime as usual. Doses above 5 mg are not typically more effective and can produce next-day grogginess that could overlap with a morning session.

Bottom line

Melatonin and ketamine have no clinically significant interaction. Melatonin is mildly sedating at typical 0.5-3 mg doses; the overlap with ketamine session sedation is small.
