Drug & supplement interaction

Banana + Glipizide

Glipizide brand names: Glucotrol, Glucotrol XL.

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 Banana and Glipizide 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

Banana and Glipizide

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 Glipizide and Banana 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 Glipizide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Glipizide is filed under 6 classifications — including sulfonylureas, antidiabetes drugs, cytochrome p450 2c9 (cyp2c9) substrates. Banana has documented interactions with 1 drug class — the most serious being levodopa (moderate) — and none of Glipizide’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 Banana and Glipizide 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.

  • Bloating or gas Additional detail

    Banana

    “Orally, banana starch isolated from green bananas has resulted in bloating, gas, cramping, and softer feces. When consumed prior to exercise, fullness and bloating during exercise have been reported. In children, nausea, vomiting, and abdominal distension have been reported when banana is used in the treatment of diarrhea.”

Reported for Banana but not commonly for Glipizide: a bowel blockage, an allergic reaction, stomach pain and high potassium.

Effects for Glipizide come from the ADVERSE REACTIONS section of its FDA label; effects for Banana come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Glipizide Is Prescribed For, and What Banana Has Been Studied For

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

Glipizide is prescribed for: Glipizide tablets and glipizide extended-release tablets are both used as an add-on to diet and exercise to improve blood sugar (glucose) control in adults with type 2 diabetes. It is not used for type 1 diabetes or diabetic ketoacidosis (a serious complication of uncontrolled blood sugar).

Banana has been studied for:

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

    Banana for stroke

    Although there has been interest in using oral banana fruit for stroke, there is insufficient reliable information about the clinical effects of banana for this purpose.

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

    Banana for diabetes

    It is unclear if oral banana starch is beneficial in patients with diabetes.

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 Glipizide on your own; if you are taking Banana for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Glipizide

This page covers Banana only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Glipizide page lists 307 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Siberian Cocklebur (major), Acai (moderate), Adrafinil (moderate) and African Wild Potato (moderate).

By severity: 2 major · 256 moderate · 49 minor.

From our pharmacist’s overview on the Glipizide page

“Glipizide (Glucotrol, Glucotrol XL) lowers blood sugar by prompting the pancreas to release more insulin, and that same power is why I read its supplement list with real seriousness. Of the 307 ingredients on file, 239 also act on blood glucose, so stacking them can drive sugar dangerously low.”

About Banana

What is Banana?

Banana
  • Source of potassium and energy
  • Digestive health and diarrhea
  • Blood pressure support
  • Heartburn and stomach ulcers (traditional)
  • Weight management

Bananas are a nutritious, widely eaten fruit that provide potassium, fiber, vitamin B6, and quick energy, and they are part of a healthy diet. While some traditional uses (like easing diarrhea or supporting blood pressure) have plausible support, most specific health claims are not strongly proven. For most people bananas are a safe food, but those with kidney problems or a latex-fruit allergy should be cautious.

Musa acuminata · Musaceae · Fruit (most common); peel, flower, and leaves are also used in some traditions · Fresh fruit, dried banana, banana powder, green (unripe) banana flour, smoothies

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

Banana: dosing

There is no official medicinal dose for bananas. As a food, one to a few bananas per day fits easily into a healthy diet for most people.For banana supplements, powders, or green banana flour, a standardized dose has not been established.

Taking Banana and Glipizide Together: Common Questions

Is it safe to take Banana with Glipizide?
We do not list a known interaction between Banana and Glipizide. 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 Banana and Glipizide have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Are Banana and Glipizide 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 Banana in each. That is a conversation for your prescriber, especially if Glipizide is being adjusted to a target.
How was the Banana and Glipizide combination checked?
Interactions in our licensed database are recorded against drug classes. Glipizide is filed under 6 classifications, and Banana has documented interactions with 1 drug class — none of Glipizide'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 Banana interact with any other medications?
Yes. Banana has 5 documented drug interactions in our database — Glipizide 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 Glipizide interact with any supplements?
Yes. Glipizide has documented interactions with 307 supplements in our database — Banana is not one of them. The Glipizide interaction page linked on this page lists every one, ranked by severity.
