Hydrazine Sulfate and Moclobemide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

MONOAMINE OXIDASE INHIBITORS (MAOIs)

Why this applies to Moclobemide

Moclobemide falls under MONOAMINE OXIDASE INHIBITORS (MAOIs) — the group Hydrazine Sulfate interacts with.

Theoretically, concomitant use with other MAOIs might increase the effects and adverse effects associated with MAOIs.
Medications with hydrazine chemical moieties (e.g., phenelzine) are known to inhibit monoamine oxidase. Theoretically, hydrazine sulfate acts as an MAOI.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with this pairing. Moclobemide is already a monoamine oxidase inhibitor (an MAOI), meaning it slows the breakdown of brain chemicals like serotonin, norepinephrine, and dopamine. Hydrazine sulfate has a hydrazine chemical structure similar to older MAOI drugs, so on paper it may act like a mild MAOI too. Stacking two MAO-blocking agents could push those brain chemicals too high, raising the risk of things like high blood pressure spikes, headache, agitation, rapid heartbeat, or in rare cases serotonin syndrome.

I want to be straight with you: this is a theoretical interaction based on chemistry, not solid human studies. On top of that, hydrazine sulfate isn't proven to help with cancer and carries real nerve and liver risks of its own. Please don't combine these without talking to your doctor or pharmacist first.

About Hydrazine Sulfate

What is Hydrazine Sulfate?

  • Cancer-related weight loss (cachexia)
  • Cancer treatment (unproven)
  • Appetite stimulation
  • Improving quality of life in advanced illness

Hydrazine sulfate is a synthetic industrial chemical that was promoted as an alternative cancer treatment, but well-designed clinical trials found it does not help people with cancer live longer or feel better. It carries real risks, including serious nerve and liver toxicity, and is not approved or recommended for any medical use. Talk with your doctor or pharmacist before considering it.
