The bottom line No known interaction

We found no known interaction between Plum 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.

Plum 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 Plum 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.

Plum safety at a glance

Plum overall Generally safe Plums and prunes are widely eaten as food and are generally safe in normal amounts.
Pregnancy Use caution Plum as a food is generally fine, but concentrated supplements are not well studied in pregnancy.
Breastfeeding Use caution Eating plums is generally considered fine, but concentrated supplement forms lack safety data.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

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. Plum has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (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.

What to actually watch for

What Plum Itself Has Been Linked To

This is not an interaction — nothing below involves Tolazamide. It is the side-effect record for Plum on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Plum, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on Additional detail

    “Orally, plum has been reported to cause gastrointestinal issues, including flatulence and diarrhea.

    In one case report, small bowel obstruction with impaction in the terminal ileum occurred in a 10-month old infant who consumed a dried plum. This was likely due to the infant being unable to properly chew the plum.

    Consumption of plum pits has also caused serious gastrointestinal adverse effects.”

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 Plum

What is Plum?

  • Constipation
  • Digestive health
  • Bone health support
  • Antioxidant source
  • General nutrition

Plums and their dried form (prunes) are common, nutritious foods that are best known for helping relieve constipation thanks to their fiber and sorbitol content. They are generally safe as food, but eating large amounts can cause gas, bloating, or loose stools. Talk to your pharmacist or doctor before using concentrated supplements, especially if you have a medical condition.

Prunus domestica · Rosaceae · Fruit (fresh and dried, also called prunes); juice · Fresh fruit, dried plums (prunes), juice, powder, capsules

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

Plum: dosing

There is no official standardized dose for plum. As a food, people often eat a small serving of dried plums or drink a small glass of plum juice to help with constipation, then adjust based on how their body responds.For supplements, powders, or capsules, follow the directions on the product label, since strength varies between products.

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.
