The bottom line No known interaction

We found no known interaction between Buckwheat and Tolazamide 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.

Buckwheat and Tolazamide

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 Tolazamide and Buckwheat 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 Buckwheat at all — not against Tolazamide, 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.

Buckwheat safety at a glance

What to actually watch for

What Buckwheat Itself Has Been Linked To

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

  • Wheezing / A severe allergic reaction / An allergic reaction Worth acting on Additional detail

    “Orally, buckwheat seems to be well tolerated. However, allergic reactions to buckwheat can occur in some adults and children. Symptoms can include skin sensitization, allergic rhinitis, asthma, conjunctivitis, nausea, vomiting, and anaphylaxis.

    Occupational exposure to buckwheat, or household exposure through sleeping on a buckwheat husk stuffed-pillow can cause sensitization, of which symptoms include allergic rhini…”

Everything above comes from the Natural Medicines adverse-effect record for Buckwheat — expand a row for the licensed statement it rests on. We haven’t matched Tolazamide 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 Tolazamide.

Overlapping uses

What Tolazamide Is Prescribed For, and What Buckwheat Has Been Studied For

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

Buckwheat has been studied for:

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

    Buckwheat for diabetes

    Preliminary clinical research shows that patients with type 2 diabetes who replace a portion of white rice or white flour with tartary buckwheat 50 grams three times daily for 4 weeks show a 3% reduction in fasting insulin and a 7% reduction in low-density lipoprotein (LDL) cholesterol compared to baseline.

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 Tolazamide on your own; if you are taking Buckwheat for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Tolazamide page

“Tolazamide (Tolinase) lowers blood sugar in type 2 diabetes, and I would handle its supplement list with care, because nearly everything listed can drag blood sugar lower still. Herbs and foods with glucose-lowering effects dominate the file, and stacked on a pill that already lowers glucose they raise the odds of hypoglycemia, blood s…”

About Buckwheat

What is Buckwheat?

Buckwheat
  • Heart and circulation health
  • Blood sugar support
  • Source of fiber and protein
  • Antioxidant support
  • Varicose veins or leg swelling (traditional)

Buckwheat is a nutritious, naturally gluten-free seed that is high in fiber, protein, and antioxidants like rutin. As a food it can be part of a heart-healthy diet, but evidence that buckwheat supplements treat specific conditions is limited. Talk to your pharmacist or doctor before using concentrated extracts.

Fagopyrum esculentum · Polygonaceae · Seeds (grain), and sometimes the herb (leaves and flowers) · Flour, groats, whole seeds, tea, capsules/tablets, and extracts

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

Buckwheat: dosing

There is no official standardized supplement dose of buckwheat. As a food, it can simply be eaten as part of a balanced diet, similar to other whole grains and seeds.For buckwheat capsules, teas, or extracts, the right amount depends on the specific product.

About Tolazamide

What Is Tolazamide Used For?

Brand name: Tolinase

  • Tolazamide is used along with diet and exercise, and sometimes with other medications, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Tolazamide is in a class of medications called sulfonylureas. Tolazamide lowers blood sugar by causing the pancreas to produce insulin (a natural substance that is needed to break down sugar in the body) and helping the body use insulin efficiently. This medication will only help lower blood sugar in people whose bodies produce insulin naturally. Tolazamide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.

Taking Buckwheat and Tolazamide Together: Common Questions

Is it safe to take Buckwheat with Tolazamide?
We do not list a known interaction between Buckwheat and Tolazamide. 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.
Are Buckwheat and Tolazamide 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 Buckwheat in each. That is a conversation for your prescriber, especially if Tolazamide is being adjusted to a target.
Does Tolazamide interact with any supplements?
Yes. Tolazamide has documented interactions with 272 supplements in our database — Buckwheat is not one of them. The Tolazamide interaction page linked on this page lists every one, ranked by severity.
