Drug & supplement interaction

Salvia Divinorum + 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 Salvia Divinorum 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.

Salvia Divinorum 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 Salvia Divinorum 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Salvia Divinorum at all — not against Tafenoquine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Salvia Divinorum safety at a glance

Salvia Divinorum overall Avoid It is a potent hallucinogen with no established medical use and limited safety data; it is also restricted or illegal in many areas.
Pregnancy Avoid There is no safety data, and a hallucinogen should not be used during pregnancy.
Breastfeeding Avoid There is no safety data, so it should be avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Salvia Divinorum 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. One of them is worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on Additional detail

    Salvia Divinorum

    “Orally or by inhalation, Salvia divinorum can cause hallucinogenic effects. These include restlessness, hyperactivity, disorientation, loss of coordination, dizziness, slurred speech, altered perceptions, changes in perception of body temperature, personal detachment or distorted body ownership, fatigue, severe mood changes, and psychosis. Most of these effects resolve within 20 minutes;”

Reported for Salvia Divinorum but not commonly for Tafenoquine: confusion, hallucinations, mood changes or irritability and tiredness.

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

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

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 Salvia Divinorum

What is Salvia Divinorum?

  • Hallucinogenic or psychedelic experiences
  • Spiritual or ritual practices
  • Recreational use
  • Traditional Mazatec healing ceremonies

Salvia divinorum is a powerful hallucinogenic plant traditionally used by the Mazatec people of Mexico and now used recreationally for its short but intense mind-altering effects. There is no proven medical use, the safety is poorly studied, and it is illegal or restricted in many places. Because its effects can be unpredictable and disorienting, we do not recommend using it.

Salvia divinorum · Lamiaceae · Leaves · Dried leaves (smoked), chewed fresh leaves, leaf extracts, tinctures

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

Salvia Divinorum: dosing

There is no established or recommended safe dose for Salvia divinorum. The strength of leaves and extracts varies widely, and concentrated products can be far more potent than plain leaves, making effects hard to predict.Because it is not a proven medicine and is restricted in many areas, we cannot recommend any specific amount.

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
Anger 14 reports
Nausea 14 reports

Taking Salvia Divinorum and Tafenoquine Together: Common Questions

Is it safe to take Salvia Divinorum with Tafenoquine?
We do not list a known interaction between Salvia Divinorum 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 Salvia Divinorum 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 Salvia Divinorum 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 Salvia Divinorum 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.
Does Tafenoquine interact with any supplements?
Yes. Tafenoquine has documented interactions with 17 supplements in our database — Salvia Divinorum is not one of them. The Tafenoquine interaction page linked on this page lists every one, ranked by severity.
