Black Nightshade + Tolazamide
Tolazamide brand name: Tolinase.
We found no known interaction between Black Nightshade 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 Nightshade 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 Nightshade 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 Nightshade 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…”

About Black Nightshade
What is Black Nightshade?
- Digestive complaints
- Skin conditions
- Inflammation
- Fever
- Liver support (traditional)
Black nightshade is a wild plant whose cooked ripe berries and leaves are eaten as food in some cultures, but unripe berries and green parts can be poisonous. Human evidence for any health benefit is very limited, and the risk of toxicity is real. Do not use it as a supplement without medical guidance, and avoid it during pregnancy and breastfeeding.

An interaction check asks whether these two react with each other — it does not ask whether Black Nightshade is a good idea for someone in your situation. Here is what our Black Nightshade record says about it on its own.
Black Nightshade: dosing
There is no established or standardized safe dose of black nightshade as a supplement. When it comes to wild plants, never guess at an amount or forage your own to use as medicine.

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 Black Nightshade — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
