Drug & supplement interaction

Hydrazine Sulfate + Pralsetinib

Pralsetinib brand name: Gavreto.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Hydrazine Sulfate and Pralsetinib 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 label for Pralsetinib states a food rule worth keeping to, and 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.

Interaction report

Hydrazine Sulfate and Pralsetinib

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 Pralsetinib 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 Pralsetinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pralsetinib is filed under 5 classifications — including qt interval-prolonging drugs, p-glycoprotein substrates, hepatotoxic drugs. 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 Pralsetinib’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

No Interaction Found — But Data Suggests Hydrazine Sulfate and Pralsetinib 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. 4 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes / Kidney problems / Bleeding or bruising Worth acting on Additional detail

How to take them

Some Pralsetinib Products Have a Food Rule — Hydrazine Sulfate Should Not Break It

At least one FDA label for a product containing Pralsetinib says to take it on an empty stomach. Most supplements — Hydrazine Sulfate included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Pralsetinib on its own and move Hydrazine Sulfate to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Pralsetinib products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.1 , 14 ) The recommended dosage in adults and pediatric patients 12 years and older is 400 mg orally once daily on an empty stomach (no food intake for at least 2 hours before and at least 1 hour after taking GAVRETO).

From the Dosage and Administration section of the FDA label we read for Pralsetinib — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Overlapping uses

What Pralsetinib 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. Pralsetinib 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.

Pralsetinib is prescribed for: Gavreto (pralsetinib) is used to treat adults with metastatic RET fusion-positive non-small cell lung cancer (NSCLC) — a type of lung cancer that has spread and carries a specific genetic alteration detected by an FDA-approved test. Gavreto is also approved for adults and children aged 12 and older with advanced or metastatic RET fusion-positive thyroid cancer who need systemic (whole-body) treatment and whose cancer no longer responds to radioactive iodine (when radioactive iodine is an appropriate option). This thyroid cancer use is under accelerated approval, meaning continued approval depends on results from confirmatory clinical trials.

Hydrazine Sulfate has been studied for:

  • Lung cancer studied, not established Hydrazine Sulfate has been studied for this. Natural Medicines rates the evidence: Likely Ineffective Read what the research shows

    Hydrazine Sulfate for lung cancer

    Taking hydrazine sulfate as an adjunct to chemotherapy is not beneficial for treating non-small cell lung cancer (NSCLC) in most patients.

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 Pralsetinib 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.

See Every Supplement That Interacts With Pralsetinib

This page covers Hydrazine Sulfate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pralsetinib page lists 181 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Beer (major) and Cesium (major).

From our pharmacist’s overview on the Pralsetinib page

“With pralsetinib (Gavreto), a targeted therapy for RET-driven lung and thyroid cancers, I would treat this list as required reading rather than background noise. Most of the interactions change how much of the drug the body actually gets: grapefruit can push its levels higher, while St.”

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 Pralsetinib Together: Common Questions

Is it safe to take Hydrazine Sulfate with Pralsetinib?
We do not list a known interaction between Hydrazine Sulfate and Pralsetinib. 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.
Do Hydrazine Sulfate and Pralsetinib have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Hydrazine Sulfate and Pralsetinib at the same time of day?
At least one FDA label for a product containing Pralsetinib says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Pralsetinib on its own and move Hydrazine Sulfate to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Are Hydrazine Sulfate and Pralsetinib 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 Pralsetinib is being adjusted to a target.
How was the Hydrazine Sulfate and Pralsetinib combination checked?
Interactions in our licensed database are recorded against drug classes. Pralsetinib is filed under 5 classifications, and Hydrazine Sulfate has documented interactions with 3 drug classes — none of Pralsetinib'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 — Pralsetinib 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 Pralsetinib interact with any supplements?
Yes. Pralsetinib has documented interactions with 181 supplements in our database — Hydrazine Sulfate is not one of them. The Pralsetinib interaction page linked on this page lists every one, ranked by severity.
