Jimson Weed 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 Jimson Weed 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 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. Jimson Weed has documented interactions with 1 drug class — the most serious being anticholinergic 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.

About Jimson Weed

What is Jimson Weed?

  • Asthma and breathing problems (historical/folk use)
  • Pain relief
  • Recreational hallucinogen (highly dangerous misuse)
  • Muscle spasms
  • Skin conditions (traditional topical use)

Jimson Weed is a highly poisonous plant that contains powerful nerve-affecting compounds, and even small amounts can cause severe poisoning, hallucinations, or death. It is not a safe supplement, and there is no reliable evidence supporting its use for any health condition. Do not use Jimson Weed in any form.

Datura stramonium · Solanaceae · Leaves, seeds, flowers, and roots · Dried plant material, smoked preparations, teas, and folk extracts (none are recommended for self-use)

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

Jimson Weed: dosing

There is no safe or established dose of Jimson Weed. The amount of toxic alkaloids varies widely from plant to plant, season to season, and even between different parts of the same plant, so there is no way to take a predictable amount.Because of this, no responsible pharmacist or doctor recommends using it.

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.
