The bottom line No known interaction

We found no known interaction between Hydrazine Sulfate and Bendamustine Hydrochloride 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.

Interaction report

Hydrazine Sulfate and Bendamustine Hydrochloride

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 Bendamustine Hydrochloride and Hydrazine Sulfate 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 Bendamustine Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bendamustine Hydrochloride is filed under 3 classifications — alkylating agents, cytochrome p450 1a2 (cyp1a2) substrates, cytochrome p450 1a2 (cyp1a2) substrates. Hydrazine Sulfate has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), isoniazid (moderate) and monoamine oxidase inhibitors (maois) (moderate) — and none of Bendamustine Hydrochloride’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.

Overlapping uses

What Bendamustine Hydrochloride Is Prescribed For, and What Hydrazine Sulfate Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Bendamustine Hydrochloride is a prescription medicine with approved uses on its FDA label. Hydrazine Sulfate is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Bendamustine Hydrochloride is prescribed for: Bendamustine hydrochloride injection is used to treat adults with chronic lymphocytic leukemia (CLL). It is also used for adults with indolent B-cell non-Hodgkin lymphoma (NHL) — a slow-growing type of blood cancer — when the disease has continued to progress during or within six months of treatment with rituximab or a rituximab-containing regimen. For CLL, how well bendamustine works compared to other first-line treatments (aside from chlorambucil) has not been fully established.

Hydrazine Sulfate has been studied for:

  • Hodgkin lymphoma studied, not established Hydrazine Sulfate has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Hydrazine Sulfate for hodgkin lymphoma

    Although there has been interest in using oral hydrazine sulfate for Hodgkin lymphoma, there is insufficient reliable information about the clinical effects of hydrazine sulfate 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 Bendamustine Hydrochloride on your own; if you are taking Hydrazine Sulfate for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Bendamustine Hydrochloride

This page covers Hydrazine Sulfate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bendamustine Hydrochloride page lists 86 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Acerola (moderate), Adrafinil (moderate), African Wild Potato (moderate), Alpha-lipoic Acid (moderate) and Ashitaba (moderate).

By severity: 62 moderate · 24 minor.

From our pharmacist’s overview on the Bendamustine Hydrochloride page

“Bendamustine (Bendeka), a chemotherapy used for certain leukemias and lymphomas, carries 86 supplement and herbal interactions on file, and none of them rates major, so this is a watch-and-adjust list rather than an alarm. Nearly all of the entries, about 80, involve the same liver enzyme, CYP1A2, which helps process bendamustine.”

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.

Not applicable (synthetic industrial chemical) · Capsules, tablets, oral solution, and injectable forms (not legally available as a supplement in the U.S.)

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

Hydrazine Sulfate: dosing

There is no safe or recommended dose of hydrazine sulfate, and it is not approved for medical use. Because it is not a legitimate supplement, no standardized, evidence-based dosing exists.We do not recommend taking it at all.

Taking Hydrazine Sulfate and Bendamustine Hydrochloride Together: Common Questions

Is it safe to take Hydrazine Sulfate with Bendamustine Hydrochloride?
We do not list a known interaction between Hydrazine Sulfate and Bendamustine Hydrochloride. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Hydrazine Sulfate and Bendamustine Hydrochloride 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 Hydrazine Sulfate in each. That is a conversation for your prescriber, especially if Bendamustine Hydrochloride is being adjusted to a target.
How was the Hydrazine Sulfate and Bendamustine Hydrochloride combination checked?
Interactions in our licensed database are recorded against drug classes. Bendamustine Hydrochloride is filed under 3 classifications, and Hydrazine Sulfate has documented interactions with 3 drug classes — none of Bendamustine Hydrochloride'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 Hydrazine Sulfate interact with any other medications?
Yes. Hydrazine Sulfate has 98 documented drug interactions in our database — Bendamustine Hydrochloride is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Bendamustine Hydrochloride interact with any supplements?
Yes. Bendamustine Hydrochloride has documented interactions with 86 supplements in our database — Hydrazine Sulfate is not one of them. The Bendamustine Hydrochloride interaction page linked on this page lists every one, ranked by severity.
