Drug & supplement interaction

Kiwi + Tafenoquine

Tafenoquine brand names: Krintafel, Arakoda.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Kiwi 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.

Kiwi 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 Kiwi 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 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. Kiwi has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (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.

What to actually watch for

No Interaction Found — But Data Suggests Kiwi and Tafenoquine 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. 2 of them are worth acting on rather than waiting out — marked below.

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

Reported for Kiwi but not commonly for Tafenoquine: a severe allergic reaction, pancreatitis, a skin rash and trouble swallowing.

Effects for Tafenoquine come from the ADVERSE REACTIONS section of its FDA label; effects for Kiwi come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 70 voluntary FDA FAERS reports for Tafenoquine 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 Tafenoquine Products Have a Food Rule — Kiwi Should Not Break It

At least one FDA label for a product containing Tafenoquine says to take it with food. If you take Kiwi 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.

( 2.1 ) Regimen Name Timing Dosage Loading regimen For each of the 3 days before travel to a malarious area 200 mg (2 of the 100 mg tablets) once daily for 3 days Maintenance regimen While in the malarious area 200 mg (2 of the 100 mg tablets) once weekly – start 7 days after the last loading regimen dose Terminal prophylaxis regimen In the week following exit from the malarious area 200 mg (2 of

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.

This page covers Kiwi 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 Kiwi

What is Kiwi?

  • Constipation and digestive health
  • Vitamin C and antioxidant support
  • Sleep support
  • Immune support
  • Heart and cholesterol health

Kiwi is a nutritious fruit that is rich in vitamin C, fiber, and antioxidants, and it is generally safe to eat as a food. The strongest evidence is for helping with constipation and overall digestive regularity, while other uses like better sleep or immune support are far less proven. People with a known kiwi or latex allergy should avoid it.

Actinidia deliciosa · Actinidiaceae · Fruit (and seeds) · Fresh fruit, dried fruit, juice, extracts, capsules, powders

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

Kiwi: dosing

There is no official or standardized dose of kiwi for any health condition. In studies on digestion and sleep, people often ate about one to two kiwifruit per day, but this is not a formal medical recommendation.For kiwi supplements, juices, or powders, follow the directions on the product label, since the amount of active ingredients varies widely between products. Simply enjoying kiwi as a fruit is a safe and easy way to get its nutrients.

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.

Depression 20 reports
Anxiety 18 reports

Taking Kiwi and Tafenoquine Together: Common Questions

Is it safe to take Kiwi with Tafenoquine?
We do not list a known interaction between Kiwi and Tafenoquine. 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 Kiwi and Tafenoquine have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Kiwi and Tafenoquine at the same time of day?
At least one FDA label for a product containing Tafenoquine says to take it with food. If you take Kiwi on an empty stomach out of habit, keep them separate and take Tafenoquine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Tafenoquine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Kiwi and Tafenoquine combination checked?
Interactions in our licensed database are recorded against drug classes. Tafenoquine is filed under 1 classification, and Kiwi has documented interactions with 2 drug classes — none of Tafenoquine'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 Kiwi interact with any other medications?
Yes. Kiwi has 289 documented drug interactions in our database — Tafenoquine 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 Tafenoquine interact with any supplements?
Yes. Tafenoquine has documented interactions with 17 supplements in our database — Kiwi is not one of them. The Tafenoquine interaction page linked on this page lists every one, ranked by severity.
