Drug & supplement interaction

Dimethylhexylamine (dmha) + Acamprosate

Acamprosate brand name: Campral.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Dimethylhexylamine (dmha) and Acamprosate 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Dimethylhexylamine (dmha) and Acamprosate

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 Acamprosate and Dimethylhexylamine (dmha) 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 Acamprosate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Acamprosate is filed under a single classification — oral drugs. Dimethylhexylamine (dmha) has documented interactions with 1 drug class — the most serious being stimulant drugs (moderate) — and none of Acamprosate’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

No Interaction Found — But Data Suggests Dimethylhexylamine (dmha) and Acamprosate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

About Dimethylhexylamine (dmha)

What is Dimethylhexylamine (dmha)?

  • Pre-workout energy
  • Fat loss and weight management
  • Athletic performance
  • Appetite suppression
  • Focus and stimulation

DMHA (dimethylhexylamine, also called octodrine) is a synthetic stimulant added to some pre-workout and weight-loss supplements, often falsely labeled as a natural plant extract. It has not been shown to be safe as a dietary supplement, has been flagged by the FDA as an unapproved and potentially dangerous ingredient, and is best avoided. Talk to a pharmacist or doctor before using any product that contains it.

Synthetic chemical compound (not from a plant) · Capsules, tablets, powders, pre-workout blends

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

Dimethylhexylamine (dmha): dosing

There is no established safe or standardized dose for DMHA, and we do not recommend taking it. Do not try to guess a dose or combine it with other stimulants such as caffeine.

Is it safe to take Dimethylhexylamine (dmha) with Acamprosate?

Do Dimethylhexylamine (dmha) and Acamprosate have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.

Interactions in our licensed database are recorded against drug classes. Acamprosate is filed under 1 classification, and Dimethylhexylamine (dmha) has documented interactions with 1 drug class — none of Acamprosate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Dimethylhexylamine (dmha) interact with any other medications?
Yes. Dimethylhexylamine (dmha) has 172 documented drug interactions in our database — Acamprosate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
