Supplements and Almotriptan.
Almotriptan is an analgesic.
Almotriptan sits in the Distil medication database. 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 Almotriptan with a regular supplement stack benefits from explicit GP or pharmacist awareness rather than assuming no interaction exists by default.
Below are the 3 documented pairs we have explicitly assessed against Almotriptan in the Distil database: 1 severe and 2 caution. 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
Last reviewed 13 September 2026. Each interaction below lists the evidence its assessment drew on: some rest on studies of the exact pair, others on mechanism evidence, where a citation may support one part of the reasoning rather than the exact combination. The evidence line on each entry says which.
Additive serotonergic activity
Severe Does 5-HTP interact with Almotriptan?
5-HTP is turned into serotonin in the body, and almotriptan is a migraine medicine that acts on serotonin receptors, so taking the two together can cause serotonin syndrome (agitation, sweating, tremor, a racing heart, confusion). Do not take 5-HTP with almotriptan; if you already take both, tell the prescriber who manages your almotriptan, and do not stop almotriptan on your own.
Evidence: Limited human data, from small studies or case reports.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Caution Does Rhodiola Rosea interact with Almotriptan?
Rhodiola has mild effects on serotonin pathways, and almotriptan is a serotonin-receptor drug used for migraine, so in theory taking them together could add to that serotonin effect. The American Headache Society reviewed the published cases of serotonin syndrome with triptans and found the evidence too weak to show a link, while still advising vigilance, so 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.
Evidence: No direct study of this exact combination yet; the caution rests on a plausible mechanism or on reports involving a related medicine.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Caution Does St John's Wort interact with Almotriptan?
St John's Wort raises serotonin in its own right, and almotriptan is a serotonin-receptor drug for migraine. In theory the two could add up. The American Headache Society reviewed the published cases of serotonin syndrome with triptans and found the evidence too weak to show a link, while still advising vigilance, and the UK prescribing information for almotriptan warns that side effects may be more common with St John's Wort. 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.
Evidence: Limited human data, from small studies or case reports.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
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 the checker decides
Every result has a source
Each pair we have assessed is cited to a published study (PMID) or the British National Formulary, so you can read the source yourself.
Four kinds of answer
Severe, caution, no known interaction, and not yet assessed. A pair we have not assessed is never shown as clear.
- Severe
- Caution
- No known interaction
- Not yet assessed
Nothing in our data is not a clearance
When nothing in our data records a problem with a pair, the result says no known interaction at typical doses, which is not a clearance: your pharmacist or GP can check the pair against your full medical history.
A full supplement review, built around you, not a generic stack.
The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.
- what your diet already covers, so you are not adding a capsule for something food is already handling
- which evidence-graded compounds are worth considering for your goals, and which were considered but left out
- what to keep, change or stop from what you already take, plus the order to introduce anything new
- how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment
The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.
