The bottom line No known interaction

We found no known interaction between Breadfruit and Niacin (prescription drug) 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 Niacin (prescription drug) states a food rule worth keeping to.

Breadfruit and Niacin (prescription drug)

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 Niacin (prescription drug) 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 Niacin (prescription drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Niacin (prescription drug) is filed under 3 classifications — including hepatotoxic 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 Niacin (prescription drug)’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 Niacin (prescription drug). 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 Niacin (prescription drug)’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Niacin (prescription drug) column appears here.

How to take them

Some Niacin (prescription drug) Products Have a Food Rule — Breadfruit Should Not Break It

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

Flushing, pruritus, and gastrointestinal distress are also greatly reduced by slowly increasing the dose of niacin and avoiding administration on an empty stomach.

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

“Prescription niacin (Niaspan, Niacor) is dosed high enough for cholesterol treatment that it can strain the liver all by itself, so this is a list to treat seriously rather than skim.

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 Niacin

What Is Niacin Used For?

Brand names: Niaspan, Niacor

Niacin is used alongside diet changes to lower high LDL (bad) cholesterol and triglycerides, and to raise HDL (good) cholesterol in adults with primary hyperlipidemia (high cholesterol) or mixed dyslipidemia (abnormal levels of several blood fats). It is also used to treat adults with very high triglyceride levels who are at risk of pancreatitis (dangerous inflammation of the pancreas) when diet alone hasn't worked.

Niacin extended-release tablets are additionally indicated to reduce the risk of a repeat nonfatal heart attack in patients who have already had a heart attack and also have high cholesterol. When used together with a bile acid binding resin, niacin extended-release tablets can slow or even reverse the buildup of plaque in the arteries (atherosclerosis) in patients with coronary artery disease and high cholesterol. Niacin is always used as part of a broader treatment plan — not as a standalone solution.

Taking Breadfruit and Niacin (prescription drug) Together: Common Questions

Is it safe to take Breadfruit with Niacin (prescription drug)?
We do not list a known interaction between Breadfruit and Niacin (prescription drug). 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 Breadfruit and Niacin (prescription drug) at the same time of day?
At least one FDA label for a product containing Niacin (prescription drug) 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 Niacin (prescription drug) on its own and move Breadfruit 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.
How was the Breadfruit and Niacin (prescription drug) combination checked?
Interactions in our licensed database are recorded against drug classes. Niacin (prescription drug) is filed under 3 classifications, and Breadfruit has documented interactions with 5 drug classes — none of Niacin (prescription drug)'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 Breadfruit interact with any other medications?
Yes. Breadfruit has 944 documented drug interactions in our database — Niacin (prescription drug) 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 Niacin (prescription drug) interact with any supplements?
Yes. Niacin (prescription drug) has documented interactions with 60 supplements in our database — Breadfruit is not one of them. The Niacin (prescription drug) interaction page linked on this page lists every one, ranked by severity.
