Drug & supplement interaction

Mugwort + Prazosin

Prazosin brand names: Minipress, Prazo, Prazin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Mugwort and Prazosin 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Mugwort and Prazosin

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 Prazosin and Mugwort 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 Mugwort at all — not against Prazosin, 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.

What to actually watch for

No Interaction Found — But Data Suggests Mugwort and Prazosin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • A stuffy or runny nose / A skin rash Additional detail

    Mugwort

    “Allergy to mugwort pollen has been reported when taken orally or inhaled. Symptoms have included asthma, rhinitis, conjunctivitis, rash, and anaphylaxis.”

    Prazosin

    Listed in the ADVERSE REACTIONS section of the FDA label for Prazosin. Read the label on DailyMed ›

Reported for Mugwort but not commonly for Prazosin: a severe allergic reaction, wheezing and mania or an unusually elevated mood.

Effects for Prazosin come from the ADVERSE REACTIONS section of its FDA label; effects for Mugwort come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,175 voluntary FDA FAERS reports for Prazosin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Prazosin Is Prescribed For, and What Mugwort Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Prazosin is a prescription medicine with approved uses on its FDA label. Mugwort is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Prazosin is prescribed for: Prazosin hydrochloride capsules are used to treat high blood pressure (hypertension). Lowering blood pressure reduces the risk of serious cardiovascular events, including strokes and heart attacks. It can be used alone or combined with other blood pressure medications, such as diuretics (water pills) or beta-blockers. Managing high blood pressure is part of a broader approach to heart health, which may also include changes to diet, exercise, and other medications as directed by your prescriber.

Mugwort has been studied for:

  • Hypertension studied, not established Mugwort has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Mugwort for hypertension

    Although there has been interest in using oral mugwort for hypertension, there is insufficient reliable information about the clinical effects of mugwort for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Prazosin on your own; if you are taking Mugwort for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Prazosin

This page covers Mugwort only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Prazosin page lists 137 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Tyramine (major) and Adrafinil (moderate).

By severity: 4 major · 112 moderate · 21 minor.

From our pharmacist’s overview on the Prazosin page

“Prazosin (Minipress) relaxes blood vessels by blocking alpha receptors, which is why doctors prescribe it for high blood pressure and, often, for PTSD nightmares. Sudden pressure drops with dizziness or fainting are already its signature risk, so the 137 supplements on this list warrant genuine attention rather than a quick skim.”

About Mugwort

What is Mugwort?

Mugwort
  • Digestive upset and poor appetite
  • Menstrual discomfort
  • Sleep support and vivid dreaming
  • Used in moxibustion (traditional Chinese medicine)
  • Mild anxiety or relaxation

Mugwort is a traditional herb used for digestion, menstrual issues, and sleep, but there is very little high-quality human research to confirm these uses. It is closely related to ragweed and can trigger allergic reactions, and it should be avoided in pregnancy. Talk with your pharmacist or doctor before using it.

Artemisia vulgaris · Asteraceae · Leaves, flowering tops, and root; sometimes essential oil · Tea, capsules, tincture, dried herb, essential oil, and moxa (used in moxibustion)

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

Mugwort: dosing

There is no well-established, standardized dose for mugwort. The amount in teas, capsules, and tinctures varies a lot between products.If you choose to use mugwort, follow the directions on the product label and do not exceed them. Avoid swallowing the concentrated essential oil.

Taking Mugwort and Prazosin Together: Common Questions

Is it safe to take Mugwort with Prazosin?
We do not list a known interaction between Mugwort and Prazosin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Mugwort and Prazosin have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Mugwort and Prazosin used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Mugwort in each. That is a conversation for your prescriber, especially if Prazosin is being adjusted to a target.
Does Prazosin interact with any supplements?
Yes. Prazosin has documented interactions with 137 supplements in our database — Mugwort is not one of them. The Prazosin interaction page linked on this page lists every one, ranked by severity.
