Drug & supplement interaction

Betaine Anhydrous + Imatinib

Imatinib brand name: Gleevec.

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 Betaine Anhydrous and Imatinib 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 Imatinib 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.

Betaine Anhydrous and Imatinib

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 Imatinib and Betaine Anhydrous 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 Betaine Anhydrous at all — not against Imatinib, 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.

Betaine Anhydrous safety at a glance

Betaine Anhydrous overall Use caution Generally well tolerated in studied doses, but check with a healthcare provider before use.
Pregnancy Use caution There is not enough reliable safety data, so it is best to avoid unless a doctor advises otherwise.
Breastfeeding Use caution Safety while breastfeeding is not well established, so caution is advised.

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 Betaine Anhydrous and Imatinib 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.

    Imatinib

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

Effects for Imatinib come from the ADVERSE REACTIONS section of its FDA label; effects for Betaine Anhydrous come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 41,419 voluntary FDA FAERS reports for Imatinib 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 Imatinib Products Have a Food Rule — Betaine Anhydrous Should Not Break It

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

Drug Administration The prescribed dose should be administered orally, with a meal and a large glass of water.

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

This page covers Betaine Anhydrous only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Imatinib page lists 153 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), Cesium (major) and Ephedra (major).

By severity: 8 major · 106 moderate · 39 minor.

From our pharmacist’s overview on the Imatinib page

“Imatinib (Gleevec) treats certain leukemias and gastrointestinal tumors, and because keeping its blood level steady is what keeps the cancer controlled, this list deserves genuine attention before you add anything to it. Most of the interactions trace back to how the body clears imatinib through an enzyme called CYP3A4.”

About Betaine Anhydrous

What is Betaine Anhydrous?

  • High homocysteine levels
  • Liver health (fatty liver)
  • Exercise performance and strength
  • Digestive support (as betaine HCl, a related form)
  • General supplementation in sports nutrition

Betaine anhydrous (also called trimethylglycine) is a compound found in foods like beets, spinach, and whole grains, and is sold as a supplement and as a prescription medicine for a rare genetic condition. It is best supported for lowering homocysteine and is studied for exercise performance, though those results are mixed. Talk to your pharmacist or doctor before starting it, especially if you are pregnant, breastfeeding, or have a medical condition.

Betaine is a naturally occurring compound; the supplement form is typically derived from sugar beets (Beta vulgaris) or made synthetically · Powder, capsules, tablets; also a prescription form (betaine anhydrous) for a specific genetic disorder

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

Betaine Anhydrous: dosing

There is no single standardized dose for betaine anhydrous as a general supplement. Do not assume more is better, since higher doses may increase side effects.

Taking Betaine Anhydrous and Imatinib Together: Common Questions

Is it safe to take Betaine Anhydrous with Imatinib?
We do not list a known interaction between Betaine Anhydrous and Imatinib. 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 Betaine Anhydrous and Imatinib have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Betaine Anhydrous and Imatinib at the same time of day?
At least one FDA label for a product containing Imatinib says to take it with food. If you take Betaine Anhydrous on an empty stomach out of habit, keep them separate and take Imatinib with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Imatinib products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Imatinib interact with any supplements?
Yes. Imatinib has documented interactions with 153 supplements in our database — Betaine Anhydrous is not one of them. The Imatinib interaction page linked on this page lists every one, ranked by severity.
