Interaction report

1-androsterone and Phenelzine Sulfate

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 Phenelzine Sulfate and 1-androsterone 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 Phenelzine Sulfate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenelzine Sulfate is filed under 6 classifications — including monoamine oxidase inhibitors (maois), antidepressant drugs, serotonergic drugs. 1-androsterone has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Phenelzine Sulfate’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-androsterone Itself Has Been Linked To

This is not an interaction — nothing below involves Phenelzine Sulfate. It is the side-effect record for 1-androsterone on its own, from the licensed Natural Medicines monograph. If something new turns up after you add 1-androsterone, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on Additional detail

    “Significant increases in serum creatinine of around 0.2 mg/dL and significant decreases in GFR of around 16.4 mL/min/1.72m2 have been reported in patients taking 1-androsterone for 4 weeks. Serum creatinine remained within normal range despite the elevation, GFR dropped below 89 mL/min/1.72m2, which is suggestive of renal impairment.”

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

About 1-androsterone

What is 1-androsterone?

1-androsterone
  • Muscle building
  • Increasing strength
  • Athletic performance
  • Body recomposition

1-Androsterone (1-DHEA or 1-Andro) is a synthetic prohormone marketed to bodybuilders for muscle and strength gains, but it has not been proven safe or effective in quality human studies. It can affect hormones and may harm the liver and other organs, so most pharmacists would recommend avoiding it.

Synthetic compound (not a plant part) · Capsules, tablets, sometimes combined with other prohormones

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

1-androsterone: dosing

There is no established safe or standard dose for 1-androsterone, and no medical guideline supports its use. Products vary widely in strength and ingredients.Because of the health risks involved, the safest choice for most people is not to use it at all. Never combine it with other prohormones or hormone products.

About Phenelzine

What Is Phenelzine Used For?

Brand name: Nardil

Phenelzine treats depression in people described as “atypical,” “nonendogenous,” or “neurotic.” These patients often have a mix of anxiety and depression, along with phobic or hypochondriacal features (intense fears or excessive worry about health).

It is rarely the first antidepressant tried. It is more suitable for people who did not respond to the drugs more commonly used. Evidence is less conclusive for severe depression with endogenous features. These uses apply to Phenelzine Sulfate tablets and Nardil tablets.

Most-Reported Side Effects for Phenelzine Sulfate

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 187 reports
Headache 138 reports
Anxiety 129 reports
Weight increased 122 reports
