Drug & supplement interaction

Chrysanthemum + Ceritinib

Ceritinib brand name: Zykadia.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Chrysanthemum and Ceritinib 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 label for Ceritinib states a food rule worth keeping to, and 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

Chrysanthemum and Ceritinib

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 Ceritinib and Chrysanthemum 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 Chrysanthemum at all — not against Ceritinib, 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.

Chrysanthemum safety at a glance

Chrysanthemum overall Use caution Generally well tolerated as a tea, but it can cause allergic reactions in sensitive people.

Pregnancy Avoid Safety during pregnancy has not been established, so it is best avoided unless your doctor approves.

Breastfeeding Avoid There is not enough reliable information on safety while breastfeeding, so caution or avoidance is wise.

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

What to actually watch for

No Interaction Found — But Data Suggests Chrysanthemum and Ceritinib 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.

Sun sensitivity Additional detail
Chrysanthemum
“Topically and via occupational exposure, chrysanthemum can cause allergic reactions. Chrysanthemum allergy symptoms can include urticaria, contact dermatitis, eczema, actinic reticuloid photosensitivity dermatitis, pollinosis, rhinoconjunctivitis, and asthma. There are numerous case reports and studies showing that allergies to Chrysanthemum are very common, with an estimated 60% of Europeans being allergic.”

Ceritinib

Listed in the ADVERSE REACTIONS section of the FDA label for Ceritinib. Read the label on DailyMed ›

Reported for Chrysanthemum but not commonly for Ceritinib: an allergic reaction, hives and wheezing.

Effects for Ceritinib come from the ADVERSE REACTIONS section of its FDA label; effects for Chrysanthemum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 2,378 voluntary FDA FAERS reports for Ceritinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Ceritinib Products Have a Food Rule — Chrysanthemum Should Not Break It

At least one FDA label for a product containing Ceritinib says to take it with food. If you take Chrysanthemum on an empty stomach out of habit, keep them separate — and take Ceritinib with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ceritinib products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION Recommended Dosage: 450 mg orally once daily with food.

From the Dosage and Administration section of the FDA label we read for Ceritinib — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Ceritinib

This page covers Chrysanthemum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ceritinib page lists 67 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Beer (major) and Cesium (major).

By severity: 10 major · 48 moderate · 9 minor.

From our pharmacist’s overview on the Ceritinib page

“Ceritinib (Zykadia) treats ALK-positive lung cancer, and its label already warns about liver injury and heart rhythm changes, so this list of 67 supplements calls for genuine care. Ten interactions rate major, and most of the risk runs along two lines the drug is already prone to: 38 ingredients can stress the liver, and 13 can prolong…”

About Chrysanthemum

What is Chrysanthemum?

Eye irritation and tired eyes
Cooling and 'heat-clearing' in traditional Chinese medicine
Cold and flu symptoms
Headache
Soothing/relaxation
High blood pressure (traditional use)

Chrysanthemum flowers are most often used as a soothing tea in traditional Chinese medicine and as a folk remedy for eye irritation, colds, and minor inflammation. Solid human evidence for these uses is limited, so it should be seen as a pleasant traditional drink rather than a proven treatment. People allergic to ragweed and related plants, and those who are pregnant or breastfeeding, should be cautious and talk to a pharmacist or doctor first.

Chrysanthemum morifolium · Asteraceae · Flowers (dried flower heads) · Tea, dried flowers, capsules, extracts, topical preparations

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

Chrysanthemum: dosing

There is no official standardized dose for chrysanthemum. It is most often used as a tea made from dried flowers, and supplement strength varies widely between products.If you choose to use it, follow the directions on the product label and start with a small amount to see how you react.

Taking Chrysanthemum and Ceritinib Together: Common Questions

Is it safe to take Chrysanthemum with Ceritinib?

We do not list a known interaction between Chrysanthemum and Ceritinib. 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 Chrysanthemum and Ceritinib 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.

Should I take Chrysanthemum and Ceritinib at the same time of day?

At least one FDA label for a product containing Ceritinib says to take it with food. If you take Chrysanthemum on an empty stomach out of habit, keep them separate and take Ceritinib with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Ceritinib products can differ — so check the directions on your own box. This is about absorption, not an interaction.

Does Ceritinib interact with any supplements?

Yes. Ceritinib has documented interactions with 67 supplements in our database — Chrysanthemum is not one of them. The Ceritinib interaction page linked on this page lists every one, ranked by severity.
