Drug & supplement interaction

Cissus Quadrangularis + Bosutinib

Bosutinib brand name: Bosulif.

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 Cissus Quadrangularis 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

Cissus Quadrangularis 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 Cissus Quadrangularis 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.

Cissus Quadrangularis safety at a glance

Cissus Quadrangula... overall Use caution Generally well tolerated in short-term use, but long-term safety is not well studied.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety data, 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 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. Cissus Quadrangularis has documented interactions with 1 drug class — the most serious being antidiabetes drugs (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 Cissus Quadrangularis 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.

    Bosutinib

    Listed in the ADVERSE REACTIONS section of the FDA label for Bosutinib. Read the label on DailyMed ›

Reported for Cissus Quadrangularis but not commonly for Bosutinib: bloating or gas, dry mouth and trouble sleeping.

Effects for Bosutinib come from the ADVERSE REACTIONS section of its FDA label; effects for Cissus Quadrangularis 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 — Cissus Quadrangularis Should Not Break It

At least one FDA label for a product containing Bosutinib says to take it with food. If you take Cissus Quadrangularis 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.

Overlapping uses

What Bosutinib Is Prescribed For, and What Cissus Quadrangularis Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Bosutinib is a prescription medicine with approved uses on its FDA label. Cissus Quadrangularis is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Bosutinib is prescribed for: Bosutinib is used to treat Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+ CML) — a type of blood cancer. It can be used for newly diagnosed patients or for those whose cancer has stopped responding to, or who cannot tolerate, a prior treatment. Bosulif (the brand-name product) is approved for adults and children 1 year and older with chronic phase Ph+ CML, and for adults with accelerated phase or blast phase Ph+ CML that is resistant or intolerant to prior therapy. Generic bosutinib tablets are approved for adults only with the same range of disease phases.

Cissus Quadrangularis has been studied for:

  • Cancer studied, not established Cissus Quadrangularis has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Cissus Quadrangularis for cancer

    Although there has been interest in using oral Cissus quadrangularis for cancer, there is insufficient reliable information about the clinical effects of Cissus quadrangularis for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Bosutinib on your own; if you are taking Cissus Quadrangularis for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Bosutinib

This page covers Cissus Quadrangularis only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bosutinib page lists 172 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Grapefruit (major) and Siberian Cocklebur (major).

By severity: 7 major · 126 moderate · 39 minor.

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 Cissus Quadrangularis

What is Cissus Quadrangularis?

Cissus Quadrangularis
  • Bone fracture healing
  • Joint pain and bone health
  • Weight management
  • Blood sugar support
  • Digestive complaints

Cissus quadrangularis is a traditional vine used mainly for bone health, joint pain, and weight management. Most of the supporting evidence comes from animal studies and a small number of human trials, so its benefits are not firmly proven. It appears reasonably well tolerated in the short term, but people who are pregnant, breastfeeding, or managing chronic conditions should talk to a doctor or pharmacist first.

Cissus quadrangularis · Vitaceae · Stems, leaves, and roots · Capsules, tablets, powder, extracts, and topical preparations

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

Cissus Quadrangularis: dosing

There is no official, standardized dose for Cissus quadrangularis. Products differ widely in their strength and how they are prepared, which makes a single recommended dose hard to give.The best approach is to follow the directions on the product label and not exceed the suggested amount. A pharmacist or doctor can help you decide whether a product and dose make sense for you, especially if you take other medicines or have health conditions.

Taking Cissus Quadrangularis and Bosutinib Together: Common Questions

Is it safe to take Cissus Quadrangularis with Bosutinib?
We do not list a known interaction between Cissus Quadrangularis 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 Cissus Quadrangularis 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 Cissus Quadrangularis 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 Cissus Quadrangularis 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.
Are Cissus Quadrangularis and Bosutinib used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Cissus Quadrangularis in each. That is a conversation for your prescriber, especially if Bosutinib is being adjusted to a target.
How was the Cissus Quadrangularis and Bosutinib combination checked?
Interactions in our licensed database are recorded against drug classes. Bosutinib is filed under 4 classifications, and Cissus Quadrangularis 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 Cissus Quadrangularis interact with any other medications?
Yes. Cissus Quadrangularis has 86 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 — Cissus Quadrangularis is not one of them. The Bosutinib interaction page linked on this page lists every one, ranked by severity.
