1,4-dmaa and Fluconazole

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 Fluconazole and 1,4-dmaa 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.

1,4-dmaa safety at a glance

1,4-dmaa overall Avoid Banned by the FDA and tied to serious cardiovascular harm; avoid use.
Pregnancy Avoid Not safe; powerful stimulants should be avoided during pregnancy.
Breastfeeding Avoid Not safe; avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Fluconazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fluconazole is filed under 7 classifications — including antifungals, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. 1,4-dmaa has documented interactions with 1 drug class — the most serious being stimulant drugs (moderate) — and none of Fluconazole’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 1,4-dmaa Itself Has Been Linked To

This is not an interaction — nothing below involves Fluconazole. It is the side-effect record for 1,4-dmaa on its own, from the licensed Natural Medicines monograph. If something new turns up after you add 1,4-dmaa, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on Additional detail

    “Orally, clinical evidence on the safety of 1,4-DMAA is lacking, although it has demonstrated stimulant and vasoconstrictive effects in animal studies. A related stimulant called 1,3-DMAA has been linked to serious adverse events in humans, including lactic acidosis, hemorrhagic stroke, heat stroke, and death.”

Everything above comes from the Natural Medicines adverse-effect record for 1,4-dmaa — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Fluconazole’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Fluconazole column appears here.

From our pharmacist’s overview on the Fluconazole page

“Fluconazole (Diflucan) treats fungal infections, and I would pair it with supplements carefully. Nearly half of the 81 ingredients with an interaction on file, 38 of them, put extra strain on the liver, which is already busy processing the antifungal.”

About 1,4-dmaa

What is 1,4-dmaa?

  • Energy and stimulation
  • Weight loss
  • Athletic performance
  • Focus and concentration

1,4-DMAA is a synthetic stimulant that the U.S. FDA has determined is not a legal dietary ingredient and considers unsafe in supplements. It has been linked to serious heart and blood pressure problems, and we recommend avoiding it entirely.

Synthetic chemical (not a true plant part) · Capsules, tablets, pre-workout powders

An interaction check asks whether these two react with each other — it does not ask whether 1,4-dmaa is a good idea for someone in your situation. Here is what our 1,4-dmaa record says about it on its own.

1,4-dmaa: dosing

There is no safe or established dose of 1,4-DMAA, and it is not a legal dietary ingredient in the United States. We do not recommend any amount.If you find a product that lists DMAA, 1,4-DMAA, or similar stimulant names on the label, do not take it, and consider reporting it.

About Fluconazole

What Is Fluconazole Used For?

Brand names: Diflucan, Diflucan Injection

Fluconazole treats infections caused by Candida and Cryptococcus fungi. Diflucan tablets and oral fluconazole tablets and suspension are approved to treat vaginal yeast infections (vaginal candidiasis), thrush in the mouth or throat (oropharyngeal candidiasis), and yeast infections of the esophagus. All forms — tablets, oral suspension, and injection — are used for cryptococcal meningitis (a serious fungal brain infection). In smaller studies, fluconazole has also shown effectiveness against Candida urinary tract infections, peritonitis (infection in the abdomen), and serious systemic (bloodstream and organ) Candida infections.

Fluconazole is also used to prevent candidiasis in people undergoing bone marrow transplants who receive chemotherapy or radiation therapy. Note that vaginal candidiasis is an approved use for the tablets and Diflucan oral products, but not for the injection or oral suspension alone.
