Avoid combining 5-HTP with tramadol. Inform your prescribing physician if you are using 5-HTP before any tramadol prescription is issued. Monitor for signs of serotonin excess including restlessness, sweating, and rapid heart rate.
Why this interaction occurs
Tramadol inhibits serotonin and norepinephrine reuptake in addition to its opioid activity. Combined use with 5-HTP increases serotonin load through both enhanced synthesis and reduced clearance, elevating the risk of serotonin syndrome.
Evidence
Evidence level: moderate.
