Interaction report

Breadfruit and Atovaquone, Proguanil

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 Atovaquone, Proguanil and Breadfruit 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.

Breadfruit safety at a glance

Breadfruit overall Use caution Breadfruit is safe as a food, but medicinal extracts and leaf teas are not well studied.
Pregnancy Use caution Eating the fruit as food is generally fine, but avoid concentrated medicinal extracts due to a lack of safety data.
Breastfeeding Use caution The fruit as food is likely fine, but medicinal preparations have not been studied, so caution is advised.

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

How we checked

Why No Interaction Is Listed for Atovaquone, Proguanil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atovaquone, Proguanil is filed under 3 classifications — cytochrome p450 2c19 (cyp2c19) substrates, seizure threshold lowering drugs, oral drugs. Breadfruit has documented interactions with 5 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and cytochrome p450 2c8 (cyp2c8) substrates (moderate) — and none of Atovaquone, Proguanil’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

What Breadfruit Itself Has Been Linked To

This is not an interaction — nothing below involves Atovaquone, Proguanil. It is the side-effect record for Breadfruit on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Breadfruit, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Hives / An allergic reaction Worth acting on Additional detail

    “Topically, exposure to breadfruit latex can cause allergic reactions such as hives and rhinitis.”

Everything above comes from the Natural Medicines adverse-effect record for Breadfruit — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Atovaquone, Proguanil’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Atovaquone, Proguanil column appears here.

How to take them

Some Atovaquone, Proguanil Products Have a Food Rule — Breadfruit Should Not Break It

At least one FDA label for a product containing Atovaquone, Proguanil says to take it with food. If you take Breadfruit on an empty stomach out of habit, keep them separate — and take Atovaquone, Proguanil 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 Atovaquone, Proguanil 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 DOSAGE AND ADMINISTRATION The daily dose should be taken at the same time each day with food or a milky drink.

From the Dosage and Administration section of the FDA label we read for Atovaquone, Proguanil — where that label names a specific product, the instruction is that product's. See the Atovaquone, Proguanil drug page ›

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 Atovaquone, Proguanil page

“Most people taking atovaquone-proguanil (Malarone) are travelers trying to prevent malaria, so this list of 54 interacting supplements deserves real attention, since anything that weakens the drug can leave you exposed to the disease itself.

About Breadfruit

What is Breadfruit?

  • Source of nutrition and energy
  • High blood pressure
  • Diabetes and blood sugar support
  • Inflammation and joint discomfort
  • Skin conditions

Breadfruit is a starchy tropical fruit eaten as a staple food, and its leaves are used in traditional medicine for conditions like high blood pressure and diabetes. As a food it is nutritious and generally safe, but the medicinal use of leaf teas or extracts has very little human research to back it up. Talk with your pharmacist or doctor before using breadfruit products for a health condition.

Artocarpus altilis · Moraceae · Fruit, seeds, leaves, and sometimes the bark or latex · Whole fruit (food), flour, leaf tea, capsules, and powders

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

Breadfruit: dosing

There is no established standardized dose for breadfruit as a medicine. When eaten as a food, normal serving sizes are used the same way you would eat potatoes or other starchy vegetables.For supplements, leaf teas, or extracts, follow the directions on the product label, since the strength of products can vary widely.

About Atovaquone and Proguanil

What Is Atovaquone and Proguanil Used For?

Brand name: Malarone

Atovaquone and proguanil is used for two purposes: preventing P. falciparum malaria before and during travel to areas where malaria is common, and treating an active, uncomplicated P. falciparum malaria infection. This includes regions where other antimalarials — such as chloroquine, mefloquine, halofantrine, and amodiaquine — may no longer be effective due to drug resistance.

Both the adult-strength and pediatric-strength tablet formulations share these same two approved uses. The brand Malarone is approved for both prevention and treatment of P. falciparum malaria in adults and in pediatric patients, with dosing based on body weight for children.
