19-nor-dhea and Diethylpropion

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 Diethylpropion 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 Diethylpropion

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diethylpropion is filed under 2 classifications — stimulant drugs, oral drugs. 19-nor-dhea has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Diethylpropion’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 Diethylpropion’s Own FDA Label Lists

This is not an interaction — none of it involves 19-nor-dhea. These are the most notable effects listed in the ADVERSE REACTIONS section of Diethylpropion’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on
  • Pain or burning when passing urine Worth acting on
  • An irregular heartbeat Worth acting on
  • Low mood Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • Hives Worth acting on
  • A low white blood cell count Worth acting on
  • Bleeding or bruising Worth acting on
  • Passing urine more often

From the ADVERSE REACTIONS section of the FDA label for Diethylpropion. Read the label on DailyMed › 19-nor-dhea’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no 19-nor-dhea side to compare — that is a limit of the record, not a statement that 19-nor-dhea has no side effects.

Overlapping uses

What Diethylpropion Is Prescribed For, and What 19-nor-dhea Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Diethylpropion is a prescription medicine with approved uses on its FDA label. 19-nor-dhea is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Diethylpropion is prescribed for: Diethylpropion is used to help manage exogenous obesity (excess body weight from outside factors like diet) in adults with a body mass index (BMI) of 30 or higher who haven't lost enough weight through diet and exercise alone. It is meant to be used for only a few weeks as part of a calorie-restricted diet plan. All available tablet products — both the immediate-release tablets and the extended-release tablets — are approved for this purpose. Each is approved for use as a single medication only; combining diethylpropion with any other weight-loss drug is not allowed.

19-nor-dhea has been studied for:

  • Obesity studied, not established 19-nor-dhea has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    19-nor-dhea for obesity

    Although there is interest in using 19-nor-DHEA for weight loss, there is insufficient reliable information about the clinical effects of 19-nor-DHEA for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Diethylpropion on your own; if you are taking 19-nor-dhea for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Diethylpropion

This page covers 19-nor-dhea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Diethylpropion page lists 61 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Peyote (major), Rauvolfia Vomitoria (major) and Sida Cordifolia (major).

By severity: 5 major · 43 moderate · 13 minor.

From our pharmacist’s overview on the Diethylpropion page

“Diethylpropion (Tenuate) is an appetite suppressant that works by revving up the nervous system, and that mechanism is why its interaction list calls for real vigilance. Of the 61 supplements and herbs on file, 44 add their own stimulant push, raising the risk of high blood pressure, a pounding heart, and sleeplessness.”

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.

Taking 19-nor-dhea and Diethylpropion Together: Common Questions

Is it safe to take 19-nor-dhea with Diethylpropion?

Are 19-nor-dhea and Diethylpropion used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for 19-nor-dhea in each. That is a conversation for your prescriber, especially if Diethylpropion is being adjusted to a target.
How was the 19-nor-dhea and Diethylpropion combination checked?
Interactions in our licensed database are recorded against drug classes. Diethylpropion is filed under 2 classifications, and 19-nor-dhea has documented interactions with 1 drug class — none of Diethylpropion'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 19-nor-dhea interact with any other medications?
Yes. 19-nor-dhea has 8 documented drug interactions in our database — Diethylpropion is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
