No Known Interaction
The bottom line No known interaction

We found no known interaction between Smartweed and Atogepant 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.

Smartweed and Atogepant

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 Atogepant and Smartweed 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.

Smartweed safety at a glance

Smartweed overall Use caution There is little modern safety data, so use cautiously and talk to a healthcare provider first.
Pregnancy Avoid Traditionally used to affect menstruation and the uterus, so avoid during pregnancy.
Breastfeeding Avoid There is not enough safety information, so it is best to avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Atogepant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atogepant is filed under 3 classifications — p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Smartweed has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Atogepant’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 Atogepant’s Own FDA Label Lists

This is not an interaction — none of it involves Smartweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Atogepant’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. 2 of them are worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on
  • An allergic reaction Worth acting on
  • Migraine mentioned in 17.7% of FDA reports for Atogepant
  • Constipation mentioned in 6.9% of FDA reports for Atogepant
  • Drowsiness
  • Reduced appetite
  • Tiredness mentioned in 6.5% of FDA reports for Atogepant
  • Nausea mentioned in 9.2% of FDA reports for Atogepant

From the ADVERSE REACTIONS section of the FDA label for Atogepant. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,568 voluntary FDA FAERS reports for Atogepant that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Smartweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Smartweed side to compare — that is a limit of the record, not a statement that Smartweed has no side effects.

See Every Supplement That Interacts With Atogepant

This page covers Smartweed only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Atogepant page lists 144 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 103 moderate · 38 minor.

From our pharmacist’s overview on the Atogepant page

“Grapefruit is the single interaction I would want every Qulipta user to know first. Atogepant, a preventive migraine medicine, is cleared by a liver enzyme called CYP3A4, and grapefruit juice blocks that enzyme, so the drug can build up and side effects become more likely.”

About Smartweed

What is Smartweed?

Smartweed
  • Digestive upset
  • Minor skin irritation
  • Heavy menstrual bleeding (traditional)
  • Wound and bleeding (traditional topical use)
  • Antioxidant and anti-inflammatory support

Smartweed (Persicaria hydropiper) is a peppery wetland plant with a long history in traditional medicine for digestive complaints, bleeding, and skin problems. Modern human studies are very limited, so its benefits are not well proven. Because safety data are thin, it's best to use cautiously and avoid it during pregnancy and breastfeeding.

Persicaria hydropiper · Polygonaceae · Aerial parts (leaves, stems, and flowering tops); sometimes the whole plant · Tea, tincture, liquid extract, dried herb, and topical preparations

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

Smartweed: dosing

There is no well-established or standardized dose for smartweed. Because it has not been carefully studied in people, experts cannot recommend a safe and effective amount.If you choose to use a product, follow the directions on the label and do not exceed them.
