Bifidobacterium Animalis Subsp. Lactis + nilotinib

nilotinib brand name: Tasigna.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Bifidobacterium Animalis Subsp. Lactis and nilotinib 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.

Interaction report

Bifidobacterium Animalis Subsp. Lactis and nilotinib

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 nilotinib and Bifidobacterium Animalis Subsp. Lactis 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 nilotinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. nilotinib is filed under 9 classifications — including cytochrome p450 2c9 (cyp2c9) inhibitors, immunosuppressants, cytochrome p450 2d6 (cyp2d6) inhibitors. Bifidobacterium Animalis Subsp. Lactis has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of nilotinib’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 Bifidobacterium Animalis Subsp. Lactis and nilotinib 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.

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

Bifidobacterium Animalis Subsp. Lactis: dosing

About Nilotinib

What Is Nilotinib Used For?

Brand name: Tasigna

  • Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
