No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Palm Oil and Quinine 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 Quinine states a food rule worth keeping to.

Palm Oil and Quinine

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 Quinine and Palm Oil 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.

How we checked

Why No Interaction Is Listed for Quinine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Quinine is filed under 5 classifications — including cytochrome p450 3a4 (cyp3a4) inhibitors, photosensitizing drugs, cytochrome p450 3a4 (cyp3a4) substrates. Palm Oil has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Quinine’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 Quinine’s Own FDA Label Lists

This is not an interaction — none of it involves Palm Oil. These are the most notable effects listed in the ADVERSE REACTIONS section of Quinine’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.

  • Loss of vision Worth acting on
  • Hearing loss Worth acting on
  • Muscle weakness Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • A slow heartbeat Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Fainting Worth acting on
  • Wheezing Worth acting on
  • An irregular heartbeat Worth acting on

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

How to take them

Some Quinine Products Have a Food Rule — Palm Oil Should Not Break It

At least one FDA label for a product containing Quinine says to take it with food. If you take Palm Oil on an empty stomach out of habit, keep them separate — and take Quinine 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 Quinine 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.

Quinine sulfate capsules should be taken with food to minimize gastric upset [see Clinical Pharmacology (12.3) ] .

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

Overlapping uses

What Quinine Is Prescribed For, and What Palm Oil Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Quinine is a prescription medicine with approved uses on its FDA label. Palm Oil is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Quinine is prescribed for: Quinine sulfate capsules (brands Qualaquin and Quinine Sulfate) are approved to treat uncomplicated Plasmodium falciparum malaria in adults. This includes strains of malaria that have become resistant to chloroquine. Quinine sulfate capsules are not approved for severe or complicated malaria, for preventing malaria, or for treating or preventing nocturnal leg cramps. Using them for leg cramps carries serious risks that outweigh any potential benefit.

Palm Oil has been studied for:

  • Malaria studied, not established Palm Oil has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Palm Oil for malaria

    It is unclear if oral palm oil is beneficial in children with malaria.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Quinine on your own; if you are taking Palm Oil for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Quinine

This page covers Palm Oil only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Quinine page lists 175 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Cinchona (major), Foxglove (major), Grapefruit (major) and Lily-of-the-valley (major).

By severity: 9 major · 125 moderate · 41 minor.

From our pharmacist’s overview on the Quinine page

“Quinine (Qualaquin) earns a genuine pause before you add any supplement, because nine of its 175 interacting ingredients are rated major, and two are as everyday as grapefruit and St. John's wort.”

About Palm Oil

What is Palm Oil?

  • Cooking and food preparation
  • Source of vitamin A (red palm oil)
  • Vitamin E (tocotrienols)
  • Skin and hair care
  • General nutrition

Palm oil is a widely used edible oil pressed from the fruit of the oil palm tree, and red palm oil is a notable source of vitamin A and vitamin E compounds called tocotrienols. As a food it is generally considered safe, but it is high in saturated fat, so it should be used in moderation as part of a balanced diet. Talk with your pharmacist or doctor before using concentrated palm-oil supplements, especially if you have heart or cholesterol concerns.

Elaeis guineensis · Arecaceae · Fruit and seed (kernel) · Cooking oil, capsules, red palm oil, tocotrienol/tocopherol supplements

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

Palm Oil: dosing

There is no official standardized dose of palm oil as a supplement. As a cooking oil, it is simply used in normal food amounts, ideally in moderation because of its saturated fat.For supplements such as red palm oil or tocotrienol products, the right amount varies by product and the reason for use.

Taking Palm Oil and Quinine Together: Common Questions

Is it safe to take Palm Oil with Quinine?
We do not list a known interaction between Palm Oil and Quinine. 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 Palm Oil and Quinine at the same time of day?
At least one FDA label for a product containing Quinine says to take it with food. If you take Palm Oil on an empty stomach out of habit, keep them separate and take Quinine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Quinine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Palm Oil and Quinine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Palm Oil in each. That is a conversation for your prescriber, especially if Quinine is being adjusted to a target.
How was the Palm Oil and Quinine combination checked?
Interactions in our licensed database are recorded against drug classes. Quinine is filed under 5 classifications, and Palm Oil has documented interactions with 1 drug class — none of Quinine'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 Palm Oil interact with any other medications?
Yes. Palm Oil has 122 documented drug interactions in our database — Quinine 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 Quinine interact with any supplements?
Yes. Quinine has documented interactions with 175 supplements in our database — Palm Oil is not one of them. The Quinine interaction page linked on this page lists every one, ranked by severity.
