Some people use melatonin alongside trazodone, and it does not carry the same serotonin syndrome consideration as supplements like 5-HTP or tryptophan. That said, both have some sedative effect, so combining them can increase grogginess for some people. Discuss this combination with your prescriber rather than assuming it is automatically fine or automatically risky.
Is it safe to take melatonin with trazodone?
Short answer: Generally considered lower-risk than many other sleep supplements, since melatonin does not share trazodone's serotonergic mechanism, but their sedative effects can still add together.
