Supplements and Zolmitriptan.
Zolmitriptan, sold under the brand names Zomig, Zomig Rapimelt, is an analgesic.
Zolmitriptan (UK brand names Zomig, Zomig Rapimelt) sits at NHSBSA prescribing rank 212 in the 2024/25 PCA statistics. The BNF classifies it under "analgesics". This means it sits outside the high-volume therapeutic classes (statins, PPIs, ACE inhibitors, SSRIs) where supplement-interaction surfaces are densely studied, and the published evidence base for specific supplement pairs is correspondingly thinner. Where interactions are documented in the Distil database, they are listed below with their clinical-reference citation; where pairs have not been explicitly assessed, the missing-item form at the bottom of the page routes them into our next curation pass. Anyone combining Zolmitriptan with a regular supplement stack benefits from explicit GP or pharmacist awareness rather than assuming no interaction exists by default.
Below are the 6 documented pairs we have explicitly assessed against Zolmitriptan in the Distil database: 6 amber. The pairs cluster around 1 mechanism: Additive serotonergic activity. Every call is cited to either a clinical reference (PMID) or the British National Formulary. Anything not on this list is either still to be assessed or beyond our database scope. The checker beneath surfaces assessments by supplement, and the missing-item form at the bottom of the page routes any uncatalogued supplement into our next curation pass.
Documented interactions
Additive serotonergic activity
5-HTP is the direct building block your body turns into serotonin, and zolmitriptan is a serotonin-receptor drug used for migraine. In theory, taking them together could add to your serotonin activity. The evidence that triptans actually cause this problem is weak and most people tolerate the combination, but it is worth telling your GP you take 5-HTP, especially if you are also on an antidepressant, and being alert to symptoms like agitation, sweating, tremor, fast heartbeat or confusion.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Tryptophan is the building block your body uses to make serotonin, and zolmitriptan is a serotonin-receptor drug used for migraine. In theory the two together could raise serotonin activity. The real-world risk looks low and most people tolerate the combination, but be alert to symptoms like agitation, sweating, shivering, tremor, muscle twitching, or a racing heart, and mention the tryptophan to your GP, especially if you also take an antidepressant.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Rhodiola has mild effects on serotonin pathways, and zolmitriptan is a serotonin-receptor drug used for migraine, so in theory taking them together could add to that serotonin effect. The real-world risk looks low and most people tolerate it, but it is worth mentioning the rhodiola to your GP, especially if you also take an antidepressant. If you notice restlessness, sweating, tremor, or a racing heart, stop and seek advice.

SAMe has its own antidepressant, serotonin-related activity, and zolmitriptan is a serotonin-receptor drug used for migraine. In theory they could add to each other's serotonin effect. Most people tolerate the combination and the real-world risk looks low, but it is worth telling your GP, and seek help if you notice agitation, sweating, shivering, tremor, or a racing heart, especially if you also take an antidepressant.

Saffron has its own mild antidepressant effect that appears to act on serotonin, and zolmitriptan is a serotonin-receptor drug used for migraine. Taking them together may add to that serotonin effect. Most people tolerate it, but mention the saffron to your GP, especially if you also take an antidepressant.

St John's Wort raises serotonin in its own right, and zolmitriptan is a serotonin-receptor drug for migraine. In theory the two could add up, though the evidence that triptans trigger serotonin syndrome is weak and most people tolerate the combination. Be alert to agitation, sweating, tremor, shivering or a racing heart, and mention the St John's Wort to your GP, especially if you also take an antidepressant.

What this list does not say. Pairs not flagged here are not implicitly safe. They are either not yet in our database, or fall outside our inclusion scope (food-supplement interactions only; for drug-drug interactions, the BNF is authoritative). Use the checker below to surface any supplement, and submit a missing item if you take something we have not catalogued.
How we grade severity, choose what's in scope, and what we exclude.
Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

This page checks the pairs you enter. The personalised Distil report goes further:
- the same graded, cited interaction check across your whole stack, not just the pairs you thought to type in
- where your current routine may be leaving you short of your goals
- the evidence-backed compounds worth adding, and the ones worth dropping
It's a paid report: £79, or £49 for the first 25 customers. The interactions check is one section of it, and you can read a real one in full before you buy.
