19-nor-dhea and Mifepristone

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 Mifepristone and 19-nor-dhea 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 Mifepristone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mifepristone is filed under 4 classifications — including qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates. 19-nor-dhea has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Mifepristone’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.

From our pharmacist’s overview on the Mifepristone page

“Mifepristone is a drug where a failed dose has real consequences, whether it is Mifeprex used to end an early pregnancy or Korlym taken daily for Cushing's syndrome, so its interaction list deserves genuine respect. Most of the 151 ingredients on file act on the CYP3A4 enzyme that clears the drug, pushing its blood level up or dragging…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. 19-nor-dhea is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every 19-nor-dhea reference on this page ↓

  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About 19-nor-dhea

What is 19-nor-dhea?

  • Muscle building and bodybuilding
  • Increasing strength
  • Athletic performance
  • Supporting hormone levels
  • Body recomposition

19-nor-DHEA is a synthetic 'prohormone' marketed to bodybuilders as a precursor to nandrolone-like compounds, not a natural plant supplement. There is very little reliable human research on its safety or effectiveness, and products like it carry real risks to the liver, hormones, and heart. We do not recommend using it without close medical supervision, and it may be banned in sports and restricted by law in some places.

Not applicable (a synthetic or semi-synthetic hormone derivative, not a plant part) · Capsules, tablets, sublingual tablets, sometimes combined in 'prohormone' supplement blends

An interaction check asks whether these two react with each other — it does not ask whether 19-nor-dhea is a good idea for someone in your situation. Here is what our 19-nor-dhea record says about it on its own.

19-nor-dhea: dosing

There is no established or medically recommended dose for 19-nor-DHEA. It has not been studied well enough to define a safe and effective amount.Products vary widely, and labels may not be accurate. Because of this, we cannot suggest a specific milligram amount.
