Interaction report

1,3-dmba and Brentuximab Vedotin

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 Brentuximab Vedotin and 1,3-dmba 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 Brentuximab Vedotin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Brentuximab Vedotin is filed under a single classification — cytochrome p450 3a4 (cyp3a4) substrates. 1,3-dmba has documented interactions with 2 drug classes — the most serious being stimulant drugs (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (minor) — and none of Brentuximab Vedotin’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 1,3-dmba Itself Has Been Linked To

This is not an interaction — nothing below involves Brentuximab Vedotin. It is the side-effect record for 1,3-dmba on its own, from the licensed Natural Medicines monograph. If something new turns up after you add 1,3-dmba, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • A heart attack Worth acting on Additional detail

    “There is currently a limited amount of information available about the adverse effects of 1,3-DMBA. However, the closely related chemical 1,3-DMAA has been linked to serious adverse effects in humans, including lactic acidosis, myocardial infarction, stroke, and death.”

Everything above comes from the Natural Medicines adverse-effect record for 1,3-dmba — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Brentuximab Vedotin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Brentuximab Vedotin column appears here.

From our pharmacist’s overview on the Brentuximab Vedotin page

“Every entry on this page traces back to a single enzyme. Brentuximab vedotin (Adcetris), an IV treatment for Hodgkin lymphoma and certain other lymphomas, carries a chemotherapy payload the body clears through CYP3A4, and I would treat this list with real care.”

About 1,3-dmba

What is 1,3-dmba?

  • Athletic and workout performance
  • Energy and stimulation
  • Weight loss and fat burning
  • Appetite suppression
  • Focus and concentration

1,3-DMBA is a synthetic stimulant chemically similar to the banned stimulant DMAA, and it is not a proven or safe dietary ingredient. The U.S. FDA considers supplements containing it adulterated, and it is banned in sports. Because of serious heart and stroke risks, it is best to avoid products that contain it.

Synthetic chemical (sometimes claimed to come from plants such as Coreopsis tinctoria or pouchong tea) · Capsules, tablets, and powders (pre-workout, fat-burner, and weight-loss products)
