The bottom line No known interaction

We found no known interaction between Lady Fern and Almotriptan in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Lady Fern and Almotriptan

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 Almotriptan and Lady Fern 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Lady Fern at all — not against Almotriptan, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Serotonin syndrome Worth acting on
  • Muscle weakness Worth acting on
  • A heart attack Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on

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

See Every Supplement That Interacts With Almotriptan

This page covers Lady Fern only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Almotriptan page lists 154 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Lithium (major), St. John's Wort (major) and 5-htp (moderate).

By severity: 4 major · 108 moderate · 42 minor.

From our pharmacist’s overview on the Almotriptan page

“St. John's wort sits at the top of my worry list for anyone taking almotriptan (Axert, Almogran) for migraines, because it revs up the CYP3A4 enzyme that clears the drug, which can leave you with less relief when the headache hits.”

About Lady Fern

What is Lady Fern?

  • Traditional digestive complaints
  • Folk remedy for intestinal worms
  • Topical use for wounds and skin irritation
  • General traditional tonic
  • Eaten as a foraged spring vegetable (fiddleheads)

Lady fern is a woodland fern used in some folk traditions and occasionally foraged for its young fronds (fiddleheads). There is very little scientific evidence to support any medicinal use, and some ferns can be unsafe if raw or improperly prepared, so caution is warranted.

Athyrium filix-femina · Athyriaceae · Rhizome (rootstock) and young fronds (fiddleheads) · Dried rhizome, traditional decoction, occasionally cooked young fronds (fiddleheads) as food

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

Lady Fern: dosing

It has not been studied enough to recommend a safe and effective amount for any condition.If you choose to use a product that contains lady fern, follow the directions on the label and do not exceed the suggested amount.

About Almotriptan

What Is Almotriptan Used For?

Brand names: Axert, Almogran

Almotriptan tablets are used to treat migraine headache attacks — with or without aura — as they happen. They are not for preventing migraines before they start.

In adults, almotriptan tablets treat acute migraine attacks. In adolescents ages 12 to 17, almotriptan tablets treat acute migraine headache pain in those who typically have attacks lasting 4 hours or more when untreated. Note that in adolescents, the effect on migraine-related symptoms such as nausea and light sensitivity was not established in clinical trials. Almotriptan is not indicated for cluster headache or for hemiplegic or basilar migraine.
