The bottom line No known interaction

We found no known interaction between Black Rice 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.

Black Rice 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 Black Rice 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 Black Rice 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.

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…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Black Rice is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Black Rice reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Black Rice and Tolazamide records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Black Rice

What is Black Rice?

Black Rice
  • Heart health support
  • Antioxidant intake
  • Digestive and gut health
  • Blood sugar and weight management
  • General nutrition

Black rice is a nutritious whole-grain food that is rich in fiber, plant protein, and antioxidant pigments called anthocyanins. Eaten as part of a balanced diet it is a healthy choice, but strong human evidence that black rice or its extracts treat or prevent specific diseases is still limited. Talk with your pharmacist or doctor before using concentrated black rice supplements.

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

Black Rice: dosing

There is no established medicinal dose for black rice. As a food, a typical serving is a cooked portion similar to other rice, included as part of a balanced diet.For supplements or extracts, follow the directions on the product label, since amounts vary by product and have not been standardized.

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.
