Drug & supplement interaction

Royal Jelly + Tafenoquine

Tafenoquine brand names: Krintafel, Arakoda.

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 Royal Jelly 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.

Interaction report

Royal Jelly 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 Royal Jelly 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.

Royal Jelly safety at a glance

Royal Jelly overall Use caution Generally well tolerated, but it can trigger serious allergic reactions in sensitive people.
Pregnancy Avoid Not enough safety information; best to avoid during pregnancy.
Breastfeeding Avoid Not enough safety information; best to avoid 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 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. Royal Jelly has documented interactions with 2 drug classes — the most serious being antihypertensive drugs (moderate) and warfarin (coumadin) (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 Royal Jelly 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.

    “In people with a history of atopy or asthma, royal jelly taken orally appears to cause a high rate of allergic symptoms including pruritus, urticaria, eczema, eyelid and facial edema, conjunctivitis, rhinorrhea, dyspnea, oral allergy syndrome, and asthma. In severe cases, royal jelly can cause status asthmaticus, anaphylaxis, and death.”

Reported for Royal Jelly but not commonly for Tafenoquine: stomach pain, a severe allergic reaction, a skin rash and itching.

Effects for Tafenoquine come from the ADVERSE REACTIONS section of its FDA label; effects for Royal Jelly 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 — Royal Jelly Should Not Break It

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

From the Dosage and Administration section of the FDA label we read for Tafenoquine — 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.

See Every Supplement That Interacts With Tafenoquine

This page covers Royal Jelly 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 Royal Jelly

What is Royal Jelly?

Royal Jelly
  • Menopausal symptoms
  • Skin health and wound care
  • Immune support
  • General energy and vitality
  • Cholesterol support
  • Eye dryness (eye drops)

Royal jelly is a nutrient-rich substance made by worker bees to feed the queen bee. People take it for menopause symptoms, energy, skin, and immune support, but solid human evidence is limited for most uses. It is generally well tolerated by most people, but it can cause serious allergic reactions, especially in those allergic to bees or with asthma.

Secretion from the glands of worker honey bees (Apis mellifera) · Capsules, softgels, fresh (frozen) jelly, liquid, powder, and skin creams

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

Royal Jelly: dosing

There is no official or standardized dose of royal jelly. The amounts used in studies have varied widely, and products differ in their strength and purity.Because there is no proven best dose, it is wise to follow the directions on the product label and not take more than recommended.

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
Post-traumatic stress disorder 15 reports

Taking Royal Jelly and Tafenoquine Together: Common Questions

Is it safe to take Royal Jelly with Tafenoquine?
We do not list a known interaction between Royal Jelly 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 Royal Jelly and Tafenoquine have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Royal Jelly 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 Royal Jelly 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 Royal Jelly and Tafenoquine combination checked?
Interactions in our licensed database are recorded against drug classes. Tafenoquine is filed under 1 classification, and Royal Jelly 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 Royal Jelly interact with any other medications?
Yes. Royal Jelly has 174 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 — Royal Jelly is not one of them. The Tafenoquine interaction page linked on this page lists every one, ranked by severity.
