Drug & supplement interaction

Myrrh + 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 Myrrh 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.

Myrrh 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 Myrrh 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. Myrrh has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and warfarin (coumadin) (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 Myrrh 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.

Overlapping uses

What Mitomycin Is Prescribed For, and What Myrrh 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. Myrrh 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.

Myrrh has been studied for:

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

    Myrrh for cancer

    Although there has been interest in using oral myrrh for cancer, there is insufficient reliable information about the clinical effects of myrrh 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 Mitomycin on your own; if you are taking Myrrh 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 Mitomycin

This page covers Myrrh 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 Myrrh

What is Myrrh?

Myrrh
  • Mouth and gum irritation
  • Sore throat
  • Minor wound and skin care
  • Digestive upset
  • Antimicrobial/antiseptic uses

Myrrh is a fragrant gum resin from Commiphora trees that has long been used in mouthwashes, throat remedies, and skin care. Modern evidence for most of its uses is limited and comes mostly from laboratory or small studies, so it should be viewed as a traditional remedy rather than a proven treatment. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy.

Commiphora myrrha · Burseraceae · Gum resin (and essential oil distilled from the resin) · Tincture, mouthwash/gargle, capsules, powder, essential oil, topical preparations, incense

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

Myrrh: dosing

There is no well-established standard dose of myrrh for any condition. Strengths vary widely between tinctures, mouthwashes, capsules, and essential oils.The safest approach is to follow the directions on the product label and not exceed them. Mouthwashes and gargles are usually diluted and not swallowed. Essential oil should never be swallowed and must be diluted before applying to the skin.

Taking Myrrh and Mitomycin Together: Common Questions

Is it safe to take Myrrh with Mitomycin?
We do not list a known interaction between Myrrh 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 Myrrh and Mitomycin have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Myrrh 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 Myrrh in each. That is a conversation for your prescriber, especially if Mitomycin is being adjusted to a target.
How was the Myrrh and Mitomycin combination checked?
Interactions in our licensed database are recorded against drug classes. Mitomycin is filed under 3 classifications, and Myrrh has documented interactions with 2 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 Myrrh interact with any other medications?
Yes. Myrrh has 88 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 — Myrrh is not one of them. The Mitomycin interaction page linked on this page lists every one, ranked by severity.
