Drug & supplement interaction

Sulforaphane + Mitomycin

Mitomycin brand names: Mutamycin, Mitosol, Jelmyto.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Sulforaphane and Mitomycin 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.

Sulforaphane and Mitomycin

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 Mitomycin and Sulforaphane 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.

Sulforaphane safety at a glance

How we checked

Why No Interaction Is Listed for Mitomycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mitomycin is filed under 3 classifications — antitumor antibiotics, topical drugs, oral drugs. Sulforaphane has documented interactions with 3 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2e1 (cyp2e1) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Mitomycin’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 Sulforaphane and Mitomycin May Share a Side Effect

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.

  • Vomiting Additional detail

    Sulforaphane

    “Orally, sulforaphane and sulforaphane-rich extracts can cause bowel discomfort, stomach upset, heartburn, and vomiting. A specific stabilized form of sulforaphane (Cavamax W6) caused mild stomach upset in 60% of subjects in a small study. However, in some clinical studies, the gastrointestinal side effects reported with sulforaphane did not occur more frequently than with placebo.”

Overlapping uses

What Mitomycin Is Prescribed For, and What Sulforaphane Has Been Studied For

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

Mitomycin is prescribed for: Mitomycin (and its brand Mutamycin) is used intravenously in combination with other chemotherapy drugs to treat disseminated adenocarcinoma (a type of cancer that has spread) of the stomach or pancreas, when other treatments have not worked. It is not intended to replace surgery or radiation therapy. Mitomycin is also the active ingredient in other products for different uses: Jelmyto treats low-grade upper tract urothelial cancer (cancer of the upper urinary tract); Zusduri treats recurrent low-grade intermediate-risk non-muscle invasive bladder cancer; and Mitosol is used as a surgical aid during certain glaucoma eye surgery. These are separate products with distinct indications and are not interchangeable with the intravenous injection form.

Sulforaphane has been studied for:

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

    Sulforaphane for cancer

    Although there is interest in using oral sulforaphane for cancer, there is insufficient reliable information about the clinical effects of sulforaphane for this condition.

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 Mitomycin on your own; if you are taking Sulforaphane for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Mitomycin

This page covers Sulforaphane only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mitomycin page lists 26 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coffee Charcoal (moderate) and Dimethylsulfoxide (dmso) (moderate).

By severity: 1 major · 15 moderate · 10 minor.

From our pharmacist’s overview on the Mitomycin page

“Activated charcoal is the entry to know first with mitomycin (Mutamycin, Mitosol, Jelmyto), a chemotherapy drug, because charcoal binds medications and can cut the amount the body receives, and it carries this list's only major rating. A weakened dose of a cancer treatment is a real loss, so I would treat these 26 interactions with gen…”

About Sulforaphane

What is Sulforaphane?

  • Antioxidant support
  • General cellular health
  • Detoxification support
  • Inflammation
  • Skin and aging concerns

Sulforaphane is a natural compound found in broccoli and other cruciferous vegetables that has shown promising antioxidant and anti-inflammatory effects in lab studies, but strong human evidence for most specific health claims is still limited. It is generally well tolerated as part of a vegetable-rich diet, but if you take a concentrated supplement, talk to your pharmacist or doctor first.

Brassicaceae · Derived from cruciferous vegetables, especially broccoli sprouts and seeds · Capsules, tablets, powders, broccoli sprout extracts, and 'broccoli seed extract' supplements often standardized to glucoraphanin

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

Sulforaphane: dosing

There is no official, standardized dose of sulforaphane. Supplements vary widely in how they are made and how much active compound they actually deliver. Many products are labeled by glucoraphanin content or by 'active sulforaphane,' and the amount of usable sulforaphane can differ depending on whether the enzyme myrosinase is present.Because of this variability, the best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Sulforaphane and Mitomycin Together: Common Questions

Is it safe to take Sulforaphane with Mitomycin?
We do not list a known interaction between Sulforaphane and Mitomycin. 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 Sulforaphane and Mitomycin have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Sulforaphane and Mitomycin 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 Sulforaphane in each. That is a conversation for your prescriber, especially if Mitomycin is being adjusted to a target.
How was the Sulforaphane and Mitomycin combination checked?
Interactions in our licensed database are recorded against drug classes. Mitomycin is filed under 3 classifications, and Sulforaphane has documented interactions with 3 drug classes — none of Mitomycin'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 Sulforaphane interact with any other medications?
Yes. Sulforaphane has 722 documented drug interactions in our database — Mitomycin 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 Mitomycin interact with any supplements?
Yes. Mitomycin has documented interactions with 26 supplements in our database — Sulforaphane is not one of them. The Mitomycin interaction page linked on this page lists every one, ranked by severity.
