The bottom line No known interaction

We found no known interaction between Tagetes and Zanamivir 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.

Tagetes and Zanamivir

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 Zanamivir 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 Zanamivir, 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.

What to actually watch for

What Tagetes Itself Has Been Linked To

This is not an interaction — nothing below involves Zanamivir. It is the side-effect record for Tagetes on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Tagetes, this list is the first place to look.

  • A skin rash Additional detail

    “Topically, ornamental marigold has been reported to cause contact dermatitis (11).”

    1. 11. Leung AY, Foster S. Encyclopedia of Common Natural Ingredients Used in Food, Drugs and Cosmetics. 2nd ed. New York, NY: John Wiley & Sons, 1996.

Everything above comes from the Natural Medicines adverse-effect record for Tagetes — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Zanamivir’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Zanamivir column appears here.

Everything else you take

See Every Supplement That Interacts With Zanamivir

This page covers Tagetes only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Zanamivir page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Zanamivir page

“Activated charcoal is the single entry I would want anyone on zanamivir (Relenza) to understand first. It holds the one major rating among the 17 supplements known to interact, because charcoal binds many drugs and can lower how much reaches the body, even when a medicine is not swallowed.”

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 Zanamivir Oral Inhalation

What Is Zanamivir Oral Inhalation Used For?

Brand name: Relenza

Relenza (zanamivir) inhalation powder is used to treat uncomplicated, acute influenza A and B in adults and children aged 7 and older — but only when symptoms have been present for no more than 2 days. The sooner treatment starts, the better.

Relenza is also used to help prevent (prophylax) influenza in adults and children aged 5 and older, including in household settings where someone is sick and in broader community outbreaks. It is not a substitute for your annual flu vaccine, and it has not been shown to prevent influenza in nursing home residents.

Most-Reported Side Effects for Zanamivir

From FAERS, the FDA’s public side-effect reporting system (2,524 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Abnormal behaviour 398 reports
Overdose 395 reports
Drug exposure during pregnancy 244 reports
Hallucination 159 reports
