5-HTP and Trazodone: Can You Take Them Together?

Use caution — significant interaction

5-HTP and Trazodone can interact. Risk of serotonin syndrome — agitation, tremor, hyperreflexia, clonus, hyperthermia and autonomic instability. Serotonin syndrome has been reported with trazodone in combination with other serotonergic agents. Do not combine without a prescriber directing it. If you take trazodone for sleep or depression, treat 5-HTP as contraindicated rather than complementary.

What the evidence says

majorconflict· moderate evidence

Trazodone is a serotonin antagonist and reuptake inhibitor; 5-HTP is a direct serotonin precursor. Combining them raises serotonergic load by two independent routes.

What to do: Do not combine without a prescriber directing it. If you take trazodone for sleep or depression, treat 5-HTP as contraindicated rather than complementary.
