Winter Cherry + Imatinib

Imatinib brand name: Gleevec.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Winter Cherry 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.

Winter Cherry 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 Winter Cherry 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.

Winter Cherry safety at a glance

Winter Cherry overall Use caution Often well tolerated for short-term use, but quality of products and long-term safety are not well established.
Pregnancy Avoid Traditionally avoided in pregnancy because of possible effects on the uterus; do not use.
Breastfeeding Avoid Not enough safety information is available, so it is best avoided while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Imatinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Imatinib is filed under 8 classifications — including antineoplastics, cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 2d6 (cyp2d6) inhibitors. Winter Cherry has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and cytochrome p450 2e1 (cyp2e1) substrates (moderate) — and none of Imatinib’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 Imatinib’s Own FDA Label Lists

This is not an interaction — none of it involves Winter Cherry. These are the most notable effects listed in the ADVERSE REACTIONS section of Imatinib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • A change in thyroid levels Worth acting on
  • Hearing loss Worth acting on
  • A bowel blockage Worth acting on
  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Dehydration Worth acting on
  • Trouble swallowing Worth acting on
  • Bleeding in the gut Worth acting on

Showing the 10 most notable of 89 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Imatinib. Read the label on DailyMed › 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. Winter Cherry’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Winter Cherry side to compare — that is a limit of the record, not a statement that Winter Cherry has no side effects.

How to take them

Some Imatinib Products Have a Food Rule — Winter Cherry Should Not Break It

At least one FDA label for a product containing Imatinib says to take it with food. If you take Winter Cherry 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.

Everything else you take

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 Winter Cherry

What is Winter Cherry?

  • Stress and anxiety
  • Fatigue and low energy
  • Sleep support
  • General vitality and tonic
  • Athletic performance

Winter Cherry is another name for ashwagandha (Withania somnifera), an herb long used in Ayurvedic medicine, most often for stress, sleep, and energy. Some small studies suggest it may help with stress and anxiety, but the evidence is still limited and not definitive. It is generally well tolerated short-term, but pregnant women should avoid it, and anyone with a health condition should check with a pharmacist or doctor first.

Withania somnifera · Solanaceae · Root, and sometimes leaves and berries · Capsules, tablets, powder (churna), root extract, tea, tinctures

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

Winter Cherry: dosing

There is no official standardized dose for Winter Cherry, and products vary widely in strength and how they are made (for example, different root extracts standardized to different amounts of withanolides).Because of this, the best advice is to follow the directions on the product label and not exceed the recommended amount. It is often used for a limited period rather than indefinitely. A pharmacist or doctor can help you choose a reputable product and decide whether it is appropriate for you.
