Drug & supplement interaction

Yarrow + Asciminib

Asciminib brand name: Scemblix.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Yarrow and Asciminib 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 Asciminib 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.

Yarrow and Asciminib

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 Asciminib and Yarrow 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 Asciminib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Asciminib is filed under 3 classifications — cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Yarrow has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Asciminib’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.

No Interaction Found — But Data Suggests Yarrow and Asciminib 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. One of them is worth acting on rather than waiting out — marked below.

How to take them

Some Asciminib Products Have a Food Rule — Yarrow Should Not Break It

At least one FDA label for a product containing Asciminib says to take it on an empty stomach. Most supplements — Yarrow included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Asciminib on its own and move Yarrow to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Asciminib 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.

The recommended dose of SCEMBLIX is taken orally without food.

From the Dosage and Administration section of the FDA label we read for Asciminib — 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 Asciminib

This page covers Yarrow only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Asciminib page lists 31 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Cannabidiol (cbd) (moderate), Cannabinol (cbn) (moderate) and Cannabis (moderate).

By severity: 1 major · 20 moderate · 10 minor.

From our pharmacist’s overview on the Asciminib page

“Asciminib (Scemblix) treats chronic myeloid leukemia, and a steady blood level is what keeps the cancer suppressed, so this list deserves real care rather than a quick skim. Seventeen of the 31 supplements on file are fibers, gums, and charcoals that can block or slow how much of each pill your gut actually absorbs.”

About Yarrow

What is Yarrow?

Yarrow
  • Wounds and minor bleeding
  • Digestive upset and cramping
  • Colds, flu, and fever
  • Skin conditions
  • Menstrual discomfort

Yarrow is a traditional herb long used for wounds, digestive complaints, and colds, but high-quality human studies are very limited, so its benefits are not well proven. It is generally used short-term, and people who are pregnant, breastfeeding, or allergic to ragweed and related plants should avoid it.

Achillea millefolium · Asteraceae · Aerial parts (leaves, flowers, and stems) and essential oil · Tea, tincture, capsules, dried herb, topical creams or ointments, and essential oil

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

Yarrow: dosing

There is no official, standardized dose for yarrow. Traditional use includes teas made from the dried herb, tinctures, and capsules, as well as creams applied to the skin.Because product strengths vary widely, the safest approach is to follow the directions on the product label and not exceed them. Yarrow is intended for short-term use, not long-term daily use.

About Asciminib

What Is Asciminib Used For?

Brand name: Scemblix

Scemblix (asciminib) is used to treat adult patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase (Ph+ CML-CP) — a type of blood cancer driven by an abnormal protein called BCR-ABL1. It covers three groups: people newly diagnosed with Ph+ CML-CP, people who have already been treated for Ph+ CML-CP, and people whose cancer carries a specific mutation called T315I that makes it harder to treat.

The use in newly diagnosed Ph+ CML-CP was approved under accelerated approval based on early response data. Continued approval for that specific use may depend on results from confirmatory trials confirming long-term clinical benefit.

Most-Reported Side Effects for Asciminib

From FAERS, the FDA’s public side-effect reporting system (3,174 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 252 reports
Nausea 175 reports
Thrombocytopenia 158 reports
Headache 134 reports
Diarrhea 130 reports

Pharmacist Counseling Corner

Taking Yarrow and Asciminib Together: Common Questions

Is it safe to take Yarrow with Asciminib?
We do not list a known interaction between Yarrow and Asciminib. 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 Yarrow and Asciminib have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Yarrow and Asciminib at the same time of day?
At least one FDA label for a product containing Asciminib says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Asciminib on its own and move Yarrow to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Yarrow and Asciminib combination checked?
Interactions in our licensed database are recorded against drug classes. Asciminib is filed under 3 classifications, and Yarrow has documented interactions with 1 drug class — none of Asciminib'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 Yarrow interact with any other medications?
Yes. Yarrow has 1 documented drug interaction in our database — Asciminib 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 Asciminib interact with any supplements?
Yes. Asciminib has documented interactions with 31 supplements in our database — Yarrow is not one of them. The Asciminib interaction page linked on this page lists every one, ranked by severity.
