Summary
L-tryptophan is a serotonin precursor, and ergotamine has serotonergic receptor activity. Combined use could theoretically add serotonergic effects, but clinical evidence of serotonin syndrome is lacking.
What this interaction means in plain words
Ergotamine and L-tryptophan have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Possible additive serotonergic effects from increased serotonin synthesis and ergot receptor agonism.
What to do
Be aware of the combination and monitor for agitation, tremor, diarrhea or hyperthermia. Stop tryptophan if serotonergic symptoms develop.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
