Methyldiazinol + Fruquintinib
Fruquintinib brand name: Fruzaqla.
We found no known interaction between Methyldiazinol and Fruquintinib 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.
Methyldiazinol and Fruquintinib
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 Fruquintinib and Methyldiazinol 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 Methyldiazinol at all — not against Fruquintinib, 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.

About Methyldiazinol
What is Methyldiazinol?
There is no reliable scientific or pharmaceutical information about a substance called "Methyldiazinol." It does not appear to be a recognized herb, dietary supplement, or well-documented compound, so we cannot confirm what it is, whether it works, or whether it is safe. Do not take any product marketed under this name without first verifying its identity and contents with a pharmacist or doctor.
An interaction check asks whether these two react with each other — it does not ask whether Methyldiazinol is a good idea for someone in your situation. Here is what our Methyldiazinol record says about it on its own.
Methyldiazinol: dosing
There is no established or safe dose for Methyldiazinol because the substance is not recognized or studied.We cannot recommend any amount. If a product label gives a dose, that does not mean it has been tested for safety.
