Agrimony and Sumatriptan

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Sumatriptan and Agrimony in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Sumatriptan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sumatriptan is filed under 4 classifications — including qt interval-prolonging drugs, serotonergic drugs, serotonergic drugs. Agrimony has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Sumatriptan’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Sumatriptan’s Own FDA Label Lists

This is not an interaction — none of it involves Agrimony. These are the most notable effects listed in the ADVERSE REACTIONS section of Sumatriptan’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • Serotonin syndrome Worth acting on
  • A heart attack Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • An allergic reaction Worth acting on
  • Migraine
  • Flushing
  • Numbness or tingling
  • Dizziness
  • Headache

From the ADVERSE REACTIONS section of the FDA label for Sumatriptan. Read the label on DailyMed › Agrimony’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Agrimony side to compare — that is a limit of the record, not a statement that Agrimony has no side effects.

From our pharmacist’s overview on the Sumatriptan page

“The supplement risk that matters most with sumatriptan (Tosymra) is serotonin overload. This migraine drug works through serotonin receptors, and 20 of the 50 interacting ingredients on file, 5-HTP among them, can push serotonin activity higher still, raising the risk of serotonin syndrome (agitation, racing heart, fever).”

About Agrimony

What is Agrimony?

Agrimony
  • Sore throat and mouth irritation
  • Mild diarrhea and digestive upset
  • Minor wounds and skin irritation
  • Gallbladder and liver complaints
  • Blood sugar support

Agrimony is a traditional European herb rich in tannins that has long been used for sore throats, mild diarrhea, and minor skin problems. Good-quality human studies are very limited, so its benefits remain unproven. If you choose to try it, use it short-term, follow the product label, and check with your pharmacist or doctor first.

Agrimonia eupatoria · Rosaceae · Dried above-ground parts (leaves, stems, flowers) and seeds · Tea, tincture, liquid extract, capsules, gargle or mouth rinse, topical preparations

An interaction check asks whether these two react with each other — it does not ask whether Agrimony is a good idea for someone in your situation. Here is what our Agrimony record says about it on its own.

Agrimony: dosing

There is no well-established, standardized dose for agrimony. Traditional use has been mainly as a tea made from the dried herb, or as a tincture or liquid extract.If you choose to use an agrimony product, follow the directions on the label and do not exceed the recommended amount.

About Sumatriptan

What Is Sumatriptan Used For?

Brand name: Tosymra

Sumatriptan is used to stop a migraine headache once it starts — with or without aura (the visual or sensory warning signs some people get before a migraine). It is available as tablets, nasal sprays, nasal capsules, and subcutaneous (under-the-skin) injections for this purpose.

Sumatriptan subcutaneous injections (brands: Imitrex injection, Sumatriptan Injection, Sumatriptan Succinate Injection) are also approved to treat acute cluster headaches in adults. Sumatriptan is not used to prevent migraines or cluster headaches — it only treats attacks once they begin.

Most-Reported Side Effects for Sumatriptan

From FAERS, the FDA’s public side-effect reporting system (46,096 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Headache 3,911 reports
Nausea 3,510 reports
Migraine 3,445 reports
Fatigue 2,617 reports
Dizziness 2,121 reports
