Drug & supplement interaction

Wahoo + Linagliptin, Metformin Hydrochloride

Linagliptin, Metformin Hydrochloride brand name: Jentadueto XR.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Wahoo and Linagliptin, Metformin Hydrochloride 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 label for Linagliptin, Metformin Hydrochloride states a food rule worth keeping to, and 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.

Wahoo and Linagliptin, Metformin Hydrochloride

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 Linagliptin, Metformin Hydrochloride 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 Linagliptin, Metformin Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Linagliptin, Metformin Hydrochloride is filed under 6 classifications — including organic cation transporter 2 (oct2) substrates, antidiabetes drugs, cytochrome p450 3a4 (cyp3a4) inhibitors. 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 Linagliptin, Metformin Hydrochloride’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.

No Interaction Found — But Data Suggests Wahoo and Linagliptin, Metformin Hydrochloride 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.

  • Stomach upset / Diarrhea Additional detail

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.”

How to take them

Some Linagliptin, Metformin Hydrochloride Products Have a Food Rule — Wahoo Should Not Break It

At least one FDA label for a product containing Linagliptin, Metformin Hydrochloride says to take it with food. If you take Wahoo on an empty stomach out of habit, keep them separate — and take Linagliptin, Metformin Hydrochloride with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Linagliptin, Metformin Hydrochloride products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Linagliptin, Metformin Hydrochloride page

“Someone taking Jentadueto XR (linagliptin and metformin) for type 2 diabetes is often the same person eyeing fenugreek, bitter melon, or gymnema, and that overlap is why this page deserves real caution. Of its 285 ingredients, 239 can lower blood sugar on their own, so stacking them on a drug already doing that job risks pushing glucos…”

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.
