Drug & supplement interaction

Tagetes + 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 Tagetes 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.

Tagetes 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 Tagetes 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Tagetes at all — not against Mitomycin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Tagetes safety at a glance

Tagetes overall Use caution Generally considered low-risk in food amounts, but the essential oil and concentrated extracts can irritate skin and lack strong safety data.
Pregnancy Avoid Avoid medicinal or essential oil use during pregnancy because safety has not been established.
Breastfeeding Avoid Not enough safety information exists, so avoid medicinal use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

No Interaction Found — But Data Suggests Tagetes 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.

Everything else you take

See Every Supplement That Interacts With Mitomycin

This page covers Tagetes 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 Tagetes

What is Tagetes?

  • Digestive upset
  • Antimicrobial and antifungal
  • Skin and wound care
  • Insect repellent
  • Eye health (lutein source from petals)

Tagetes (marigold) is a group of flowering plants used in traditional medicine and as a source of plant pigments like lutein. Human evidence for most health benefits is very limited, and the essential oil can cause skin reactions and sun sensitivity. Talk to a pharmacist or doctor before using it, especially while pregnant or breastfeeding.

Asteraceae · Flowers, leaves, and essential oil · Essential oil, tea, dried flowers, topical preparations, tinctures

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

Tagetes: dosing

There is no well-established standard dose for Tagetes as a supplement or medicine. Products vary widely in strength, and the amount of active compounds depends on the species, plant part, and how it was prepared.If you choose to use a Tagetes product, follow the directions on the label and do not exceed them. Essential oils should be diluted before any skin use and kept away from the eyes and mouth.

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 Tagetes and Mitomycin Together: Common Questions

Is it safe to take Tagetes with Mitomycin?
We do not list a known interaction between Tagetes 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 Tagetes 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.
Does Mitomycin interact with any supplements?
Yes. Mitomycin has documented interactions with 26 supplements in our database — Tagetes is not one of them. The Mitomycin interaction page linked on this page lists every one, ranked by severity.
