Drug & supplement interaction

Magnolia + 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 Magnolia 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.

Interaction report

Magnolia 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 Magnolia 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. Magnolia has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and cns depressants (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 Magnolia 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.

  • Tiredness Additional detail

    Magnolia

    “In a clinical trial of an oral combination product containing extracts of magnolia and phellodendron, one patient reported shaking hands and perilabial numbness. Another patient reported fatigue and headache. However, it's not known if these side effects are related to magnolia or some other factor.”

Reported for Magnolia but not commonly for Mitomycin: erection problems, heartburn, headache and numbness or tingling.

Effects for Mitomycin come from the ADVERSE REACTIONS section of its FDA label; effects for Magnolia come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Mitomycin

This page covers Magnolia 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 Magnolia

What is Magnolia?

Magnolia
  • Anxiety and stress
  • Sleep problems
  • Digestive upset
  • Inflammation
  • Nasal congestion and allergies (flower bud)

Magnolia bark and flower buds have a long history in traditional Chinese and Japanese medicine, often for stress, sleep, and digestion. Modern human research is still limited, so we can't be sure how well it works for most uses. Talk with your pharmacist or doctor before trying it, especially if you take other medicines or are pregnant.

Magnolia officinalis · Magnoliaceae · Bark and flower buds · Capsules, tablets, tea, tinctures, and some toothpastes or skin products

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

Magnolia: dosing

There is no well-established standard dose of Magnolia. Products vary widely in how they are prepared and how concentrated they are, and many supplements combine Magnolia with other ingredients.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

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 Magnolia and Mitomycin Together: Common Questions

Is it safe to take Magnolia with Mitomycin?
We do not list a known interaction between Magnolia 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 Magnolia 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 Magnolia and Mitomycin combination checked?
Interactions in our licensed database are recorded against drug classes. Mitomycin is filed under 3 classifications, and Magnolia 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 Magnolia interact with any other medications?
Yes. Magnolia has 351 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 — Magnolia is not one of them. The Mitomycin interaction page linked on this page lists every one, ranked by severity.
