Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Kamala and Mefloquine 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 Mefloquine states a food rule worth keeping to.

Kamala and Mefloquine

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 Mefloquine and Kamala 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 Kamala at all — not against Mefloquine, 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.

What Mefloquine’s Own FDA Label Lists

This is not an interaction — none of it involves Kamala. These are the most notable effects listed in the ADVERSE REACTIONS section of Mefloquine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Thoughts of self-harm Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Unsteadiness Worth acting on
  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Mefloquine. Read the label on DailyMed › Kamala’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Kamala side to compare — that is a limit of the record, not a statement that Kamala has no side effects.

How to take them

Some Mefloquine Products Have a Food Rule — Kamala Should Not Break It

At least one FDA label for a product containing Mefloquine says to take it on an empty stomach. Most supplements — Kamala included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Mefloquine on its own and move Kamala to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Mefloquine 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.

The drug should not be taken on an empty stomach and should be administered with at least 8 oz (240 mL) of water.

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

From our pharmacist’s overview on the Mefloquine page

“Mefloquine (Lariam) prevents and treats malaria and carries its own well-known warnings about seizures and psychiatric effects, so I take this interaction list more seriously than most. Six of the 23 supplements on file, including ginkgo and melatonin, may lower the seizure threshold, a poor match for a drug with mefloquine's neurologi…”

About Kamala

What is Kamala?

  • Intestinal worms (especially tapeworm)
  • Skin conditions and parasites
  • Constipation/laxative effect
  • Wound care (traditional)
  • Use as a natural orange-red dye

Kamala is a red powder from the fruit of the Mallotus philippensis tree, used in traditional medicine mainly to expel intestinal worms and as a dye. Modern human evidence for its safety and effectiveness is very limited, and it can cause significant digestive upset, so it should only be used under professional guidance, if at all.

Mallotus philippensis · Euphorbiaceae · Red powder (glands and hairs) from the surface of the fruit; sometimes bark and leaves · Powder, capsules, traditional preparations; also used historically as a dye

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

Kamala: dosing

There is no well-established, standardized dose of Kamala supported by modern clinical research. Do not exceed the recommended amount, and avoid using it for self-treatment of worm infections without medical guidance, since safer and better-studied options are available.

About Mefloquine

What Is Mefloquine Used For?

Brand name: Lariam

Mefloquine Hydrochloride tablets are used to treat mild to moderate acute malaria caused by Plasmodium falciparum (including strains resistant to chloroquine) and Plasmodium vivax. They are also used to prevent malaria infections, including chloroquine-resistant strains of P. falciparum, in people traveling to malaria-endemic areas.

Important note: mefloquine does not eliminate the liver stage of P. vivax, so patients treated for P. vivax malaria usually need an additional medication (such as primaquine) afterward to prevent relapse.

Taking Kamala and Mefloquine Together: Common Questions

Is it safe to take Kamala with Mefloquine?
We do not list a known interaction between Kamala and Mefloquine. 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.
Should I take Kamala and Mefloquine at the same time of day?
At least one FDA label for a product containing Mefloquine says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Mefloquine on its own and move Kamala to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Mefloquine interact with any supplements?
Yes. Mefloquine has documented interactions with 23 supplements in our database — Kamala is not one of them. The Mefloquine interaction page linked on this page lists every one, ranked by severity.
