Drug & supplement interaction

Horseradish + Bosutinib

Bosutinib brand name: Bosulif.

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 Horseradish and Bosutinib 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 Bosutinib 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

Horseradish and Bosutinib

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 Bosutinib and Horseradish 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.

Horseradish safety at a glance

Horseradish overall Use caution Food amounts are generally safe, but concentrated supplements may irritate the digestive tract and mucous membranes.

How we checked

Why No Interaction Is Listed for Bosutinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bosutinib is filed under 4 classifications — including nephrotoxic drugs, hepatotoxic drugs, cytochrome p450 3a4 (cyp3a4) substrates. Horseradish has documented interactions with 1 drug class — the most serious being thyroid hormone (moderate) — and none of Bosutinib’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 Horseradish and Bosutinib 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.

  • Diarrhea / Stomach upset / Vomiting reported in 23.2% of FDA reports for Bosutinib Additional detail

    Horseradish

    “Orally, consuming large amounts of horseradish can cause gastrointestinal upset, bloody vomiting and diarrhea (2,6), and irritation of mucous membranes (2,4).”

    Bosutinib

    Listed in the ADVERSE REACTIONS section of the FDA label for Bosutinib, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Horseradish but not commonly for Bosutinib: an allergic reaction, sweating, a fast or pounding heartbeat and fainting.

Effects for Bosutinib come from the ADVERSE REACTIONS section of its FDA label; effects for Horseradish come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 8,931 voluntary FDA FAERS reports for Bosutinib 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 Bosutinib Products Have a Food Rule — Horseradish Should Not Break It

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

Adult patients with newly-diagnosed chronic phase Ph+ CML: 400 mg orally once daily with food.

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

From our pharmacist’s overview on the Bosutinib page

“Grapefruit is the first thing to know about if you take bosutinib (Bosulif) for chronic myeloid leukemia. Bosutinib is cleared by the enzyme CYP3A4, and grapefruit blocks that pathway, so drug levels climb and side effects with them.”

About Horseradish

What is Horseradish?

  • Sinus and respiratory congestion
  • Urinary tract infections
  • Digestive support
  • Antimicrobial
  • Culinary flavoring

Horseradish is a pungent root used as a food and folk remedy, most often for sinus congestion and urinary tract complaints. Human evidence is limited, and while culinary amounts are generally well tolerated, concentrated supplements can irritate the stomach and should be used cautiously. Talk with your pharmacist or doctor before using horseradish as a medicine.

Armoracia rusticana · Brassicaceae · Root (fresh or dried) · Fresh grated root, dried root powder, prepared condiment (sauce), capsules, tinctures

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

Horseradish: dosing

There is no well-established standardized medicinal dose for horseradish. Amounts used in research and traditional practice vary widely depending on the form (fresh root, dried powder, or extract).If you use a commercial supplement, follow the directions on the product label and do not exceed the recommended amount. Avoid taking large or concentrated amounts in hopes of stronger effects, since this mainly increases the risk of irritation and side effects.

Taking Horseradish and Bosutinib Together: Common Questions

Is it safe to take Horseradish with Bosutinib?
We do not list a known interaction between Horseradish and Bosutinib. 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 Horseradish and Bosutinib have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Horseradish and Bosutinib at the same time of day?
At least one FDA label for a product containing Bosutinib says to take it with food. If you take Horseradish on an empty stomach out of habit, keep them separate and take Bosutinib with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Bosutinib products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Horseradish and Bosutinib combination checked?
Interactions in our licensed database are recorded against drug classes. Bosutinib is filed under 4 classifications, and Horseradish has documented interactions with 1 drug class — none of Bosutinib'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 Horseradish interact with any other medications?
Yes. Horseradish has 16 documented drug interactions in our database — Bosutinib 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 Bosutinib interact with any supplements?
Yes. Bosutinib has documented interactions with 172 supplements in our database — Horseradish is not one of them. The Bosutinib interaction page linked on this page lists every one, ranked by severity.
