We found no known interaction between Wahoo and Alfentanil in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Wahoo and Alfentanil

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 Alfentanil and Wahoo 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 Alfentanil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alfentanil is filed under 6 classifications — including anesthesia, narcotic drugs, cns depressants. Wahoo has documented interactions with 6 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and macrolide antibiotics (moderate) — and none of Alfentanil’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 Wahoo Itself Has Been Linked To

This is not an interaction — nothing below involves Alfentanil. It is the side-effect record for Wahoo on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Wahoo, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Shortness of breath Worth acting on Additional detail

    “Wahoo is considered poisonous (17). Several hours after ingesting wahoo seeds, people experience severe upset stomach, sometimes with bloody diarrhea, fever, shortness of breath, circulatory problems, signs of collapse, stupor increasing to unconsciousness, alternating with motor restlessness, severe tonic-clonic spasms with locked jaw muscles and coma.”

We haven’t matched Alfentanil to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Alfentanil.

From our pharmacist’s overview on the Alfentanil page

“Alfentanil (Alfenta) is a potent, fast-acting opioid, usually given during surgery, and that potency is why this page deserves genuine care rather than a passing glance. Ten of the 202 ingredients listed are rated major, and they cluster into two problems: extra sedation stacked on a drug that already suppresses breathing, and changes…”

About Wahoo

What is Wahoo?

Wahoo
  • Constipation (traditional laxative)
  • Digestive complaints
  • Liver and gallbladder support (folk use)
  • Fluid retention (traditional diuretic)
  • Skin irritations (folk use)

Wahoo is a North American shrub historically used as a laxative and 'liver tonic,' but it is a poisonous plant with no proven benefit and a real risk of serious harm. Because it contains heart-affecting and other toxic compounds, we do not recommend using it, and there is no established safe dose.

Euonymus atropurpureus · Celastraceae · Dried root bark and stem bark (historically) · Historically tinctures, extracts, and powdered bark; rarely available today

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

Wahoo: dosing

There is no established safe or effective dose of wahoo, and we do not recommend using it. In most cases the safest choice is to avoid it entirely and use a better-studied, safer option instead.

From our Wahoo monograph — the full record covers uses, side effects and every documented interaction.
