Drug & supplement interaction

Androstenetrione + nefazodone

nefazodone brand name: Serzone.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Androstenetrione and nefazodone 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.

Androstenetrione and nefazodone

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 nefazodone and Androstenetrione 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 nefazodone

Interactions in our licensed database are recorded against drug classes, not just single drug names. nefazodone is filed under 6 classifications — including antidepressant drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, serotonergic drugs. Androstenetrione has documented interactions with 1 drug class — the most serious being androgens (minor) — and none of nefazodone’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.

No Interaction Found — But Data Suggests Androstenetrione and nefazodone 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.

    Androstenetrione

    “There is no data regarding oral use of androstenetrione in humans. However, androstenetrione might increase testosterone levels. Theoretically, androstenetrione might cause testosterone-like side effects including spermatogenesis and infertility, acne, testicular atrophy, gynecomastia, behavioral changes, cardiovascular disease, and potentially increase the risk of pancreatic and prostate cancer.”

From our pharmacist’s overview on the nefazodone page

“Nefazodone (Serzone) treats depression by working on serotonin, and it also strongly blocks a liver enzyme called CYP3A4, which is exactly why this list deserves your close attention. The largest group, 121 ingredients, are ones nefazodone can push to higher levels because it slows their breakdown.”

About Androstenetrione

What is Androstenetrione?

Androstenetrione
  • Boosting testosterone
  • Lowering estrogen
  • Bodybuilding and muscle building
  • Post-cycle support for steroid users
  • Athletic performance

Androstenetrione (6-OXO) is a synthetic compound marketed to raise testosterone by blocking the enzyme that turns testosterone into estrogen. Solid human evidence that it offers real benefits is lacking, and it can cause hormone-related side effects, so most people should avoid it and talk with a healthcare provider first.

Synthetic compound (not from a plant) · Capsules, tablets

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

Androstenetrione: dosing

There is no established, standardized dose for androstenetrione, and no dose has been proven safe and effective. Different products contain different amounts.Because of the hormone-related risks and weak evidence, we cannot recommend a specific amount.

About Nefazodone

What Is Nefazodone Used For?

Brand name: Serzone

Nefazodone Hydrochloride tablets are approved to treat depression, specifically major depressive disorder (MDD). Clinical trials established its effectiveness over 6 to 8 weeks in outpatients and 6 weeks in hospitalized patients with depression.

Nefazodone has also been shown to help prevent depression from coming back in patients who responded well to initial treatment. Because of a serious risk of liver failure, prescribers are advised to consider other antidepressants before turning to nefazodone.
