Banana + Tafenoquine
Tafenoquine brand names: Krintafel, Arakoda.
We found no known interaction between Banana and Tafenoquine 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 Tafenoquine 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.
Banana and Tafenoquine
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 Tafenoquine 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.
Banana safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Tafenoquine
Interactions in our licensed database are recorded against drug classes, not just single drug names. Tafenoquine is filed under a single classification — oral drugs. Banana has documented interactions with 1 drug class — the most serious being levodopa (moderate) — and none of Tafenoquine’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.
Banana Does Interact With Other Medications
Banana has 5 moderate known drug interactions in our database — Tafenoquine isn’t one of them. If you take anything else, check it against the full list below.

Some Tafenoquine Products Have a Food Rule — Banana Should Not Break It
At least one FDA label for a product containing Tafenoquine says to take it with food. If you take Banana on an empty stomach out of habit, keep them separate — and take Tafenoquine 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 Tafenoquine 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.

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 Tafenoquine
This page covers Banana only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tafenoquine page lists 17 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).
By severity: 1 major · 7 moderate · 9 minor.
From our pharmacist’s overview on the Tafenoquine page
“Tafenoquine (Krintafel, Arakoda) protects against malaria, including the relapsing kind that hides in the liver, and every supplement known to interact with it threatens the same thing, how much of the pill actually reaches your blood. That deserves genuine care, since a partly absorbed antimalarial can let parasites survive and resurf…”

About Banana
What is 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.
From our Banana monograph — the full record covers uses, side effects and every documented interaction.
About Tafenoquine
What Is Tafenoquine Used For?
Brand names: Krintafel, Arakoda
Tafenoquine is used for two distinct purposes depending on the product. Arakoda and Kodatef are used for malaria prophylaxis — that is, preventing malaria in adults 18 and older who are traveling to or living in areas where malaria is present.
Krintafel is used for the radical cure of Plasmodium vivax malaria — meaning it prevents the malaria parasite from coming back (relapsing) in patients 16 and older who are already being treated with chloroquine for an active P. vivax infection. Krintafel is not used to treat an active malaria attack on its own, and it should only be used alongside chloroquine, not other antimalarials.
Most-Reported Side Effects for Tafenoquine
From FAERS, the FDA’s public side-effect reporting system (70 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
