Drug & supplement interaction

Levilactobacillus Brevis + Mitomycin

Mitomycin brand names: Mutamycin, Mitosol, Jelmyto.

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 Levilactobacillus Brevis 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.

Levilactobacillus Brevis 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 Levilactobacillus Brevis 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 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. Levilactobacillus Brevis has documented interactions with 1 drug class — the most serious being antibiotic drugs (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 Levilactobacillus Brevis and Mitomycin 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. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

    Levilactobacillus Brevis

    “Since Levilactobacillus brevis preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Some lactobacilli species have been isolated in cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis.”

Everything else you take

See Every Supplement That Interacts With Mitomycin

This page covers Levilactobacillus Brevis 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 Levilactobacillus Brevis

What is Levilactobacillus Brevis?

  • Digestive health
  • Gut microbiome support
  • Immune support
  • Oral and dental health
  • Vaginal health

Levilactobacillus brevis (formerly Lactobacillus brevis) is a lactic acid bacterium found in fermented foods like sauerkraut, pickles, and kimchi, and is used as a probiotic. Early research suggests possible benefits for gut and immune health, but strong human evidence is still limited. It is generally well tolerated in healthy people, but anyone with a weakened immune system or serious illness should talk to a doctor first.

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

Levilactobacillus Brevis: dosing

There is no official standardized dose for Levilactobacillus brevis. Probiotic amounts are usually measured in colony-forming units (CFU), and products vary widely in strength and strain.The best approach is to follow the directions on the product label. Doses are often taken once or twice daily, sometimes with food.

About Mitomycin

What Is Mitomycin Used For?

Brand names: Mutamycin, Mitosol, Jelmyto

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.

Taking Levilactobacillus Brevis and Mitomycin Together: Common Questions

Is it safe to take Levilactobacillus Brevis with Mitomycin?
We do not list a known interaction between Levilactobacillus Brevis 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 Levilactobacillus Brevis and Mitomycin have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
How was the Levilactobacillus Brevis and Mitomycin combination checked?
Interactions in our licensed database are recorded against drug classes. Mitomycin is filed under 3 classifications, and Levilactobacillus Brevis has documented interactions with 1 drug class — 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 Levilactobacillus Brevis interact with any other medications?
Yes. Levilactobacillus Brevis has 182 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 — Levilactobacillus Brevis is not one of them. The Mitomycin interaction page linked on this page lists every one, ranked by severity.
