Great Plantain + Tolazamide
Tolazamide brand name: Tolinase.
We found no known interaction between Great Plantain 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.
Great Plantain 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 Great Plantain 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.

Why No Interaction Is Listed for Tolazamide
Interactions in our licensed database are recorded against drug classes, not just single drug names. Tolazamide is filed under 3 classifications — antidiabetes drugs, photosensitizing drugs, oral drugs. Great Plantain has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Tolazamide’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.

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 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.

Tolazamide Is Linked to Lower Levels of One Nutrient
Natural Medicines records Tolazamide as a medicine that can lower these. This is not an interaction with Great Plantain — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
