The bottom line No known interaction

We found no known interaction between Masterwort and Etomidate 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.

Masterwort and Etomidate

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 Etomidate and Masterwort 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.

Masterwort safety at a glance

Masterwort overall Use caution Limited safety data exist, and the plant can cause sun-triggered skin reactions.

How we checked

Why No Interaction Is Listed for Etomidate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Etomidate is filed under a single classification — anesthesia. Masterwort has documented interactions with 1 drug class — the most serious being photosensitizing drugs (moderate) — and none of Etomidate’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.

Keep it in perspective

What to actually watch for

What Etomidate’s Own FDA Label Lists

This is not an interaction — none of it involves Masterwort. These are the most notable effects listed in the ADVERSE REACTIONS section of Etomidate’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. 4 of them are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on
  • Blood clots Worth acting on
  • Seizures Worth acting on
  • Raised blood pressure Worth acting on
  • Low blood pressure mentioned in 6.9% of FDA reports for Etomidate
  • A fast or pounding heartbeat
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Etomidate. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,215 voluntary FDA FAERS reports for Etomidate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Masterwort’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Masterwort side to compare — that is a limit of the record, not a statement that Masterwort has no side effects.

Everything else you take

See Every Supplement That Interacts With Etomidate

This page covers Masterwort only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Etomidate page lists 5 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Fever Bark (major), Cannabis (moderate), Cowhage (moderate), Datura Wrightii (moderate) and Delta-9-tetrahydrocannabinol (thc) (moderate).

By severity: 1 major · 4 moderate.

From our pharmacist’s overview on the Etomidate page

“Etomidate is not a pill you take at home. It is an intravenous drug used to put you under quickly for surgery or emergency procedures, and that shapes what this short list of five interacting supplements means.”

About Masterwort

What is Masterwort?

Masterwort
  • Digestive upset
  • Mild anxiety and tension
  • Skin complaints
  • Respiratory and cough relief
  • Traditional tonic

Masterwort (Heracleum sphondylium), a plant in the carrot family, has a long folk-medicine history for digestion, nerves, and skin. Modern scientific evidence to support these uses is very limited, and the plant can cause skin reactions to sunlight, so use it cautiously and talk with your pharmacist or doctor first.

Heracleum sphondylium · Apiaceae · Root, leaves, seeds, and aerial parts · Tea, tincture, dried herb, essential oil

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

Masterwort: dosing

There is no standardized, well-established dose for masterwort. Traditional preparations vary widely, and product strengths are not consistent.If you choose to use a commercial product, follow the directions on the label and do not exceed the suggested amount.

About Etomidate

What Is Etomidate Used For?

Brand name: Amidate

Etomidate — available as Amidate and under the generic name Etomidate — is given by intravenous (IV) injection to induce general anesthesia before surgery or other procedures. It brings on unconsciousness rapidly, usually within about one minute.

Amidate and etomidate injection products are also used to supplement weaker anesthetic agents, such as nitrous oxide in oxygen, during short operative procedures — for example, dilation and curettage (D&C) or cervical conization. This supplemental use is supported only for adult patients in short procedures; it is not recommended for longer procedures or for pediatric patients.

Most-Reported Side Effects for Etomidate

From FAERS, the FDA’s public side-effect reporting system (2,215 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Renal failure 239 reports
Injury 186 reports
Anxiety 180 reports
Unevaluable event 168 reports
