Drug & supplement interaction

Rose Geranium Oil + Quinine

Quinine brand name: Qualaquin.

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 Rose Geranium 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, 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.

Interaction report

Rose Geranium 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 Rose Geranium 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Rose Geranium Oil at all — not against Quinine, 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.

Rose Geranium Oil safety at a glance

Rose Geranium Oil overall Use caution Generally considered safe for diluted topical or aromatherapy use, but it can irritate skin and should not be swallowed.
Pregnancy Avoid Safety is not well studied, so it is best to avoid medicinal use during pregnancy.

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

No Interaction Found — But Data Suggests Rose Geranium Oil and Quinine May Share a Side Effect

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.

Effects for Quinine come from the ADVERSE REACTIONS section of its FDA label; effects for Rose Geranium Oil come from the Natural Medicines adverse-effect record, quoted above. 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 Quinine Products Have a Food Rule — Rose Geranium Oil Should Not Break It

At least one FDA label for a product containing Quinine says to take it with food. If you take Rose Geranium 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.

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 Rose Geranium Oil

What is Rose Geranium Oil?

  • Skin care and complexion
  • Aromatherapy for stress and mood
  • Insect and tick repellent
  • Minor wound and skin soothing
  • Fragrance

Rose geranium oil is an essential oil distilled from the leaves of Pelargonium graveolens, used mainly in aromatherapy, skincare, and as a natural fragrance. High-quality human evidence for medical benefits is limited, and like all essential oils it must be diluted before skin use and never swallowed. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have sensitive skin.

Pelargonium graveolens · Geraniaceae · Leaves and stems (steam-distilled essential oil) · Essential oil, diluted topical blends, aromatherapy products, soaps and skincare items

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

Rose Geranium Oil: dosing

There is no established standardized medical dose for rose geranium oil. It is used mainly topically (in diluted form) or by inhaling its scent, not by mouth.For skin use, essential oils are typically mixed at a low concentration in a carrier oil, but you should follow the specific instructions on your product label.

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.

Taking Rose Geranium Oil and Quinine Together: Common Questions

Is it safe to take Rose Geranium Oil with Quinine?
We do not list a known interaction between Rose Geranium 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.
Do Rose Geranium Oil and Quinine have any of the same side effects?
Yes — our sources link each of them separately to one 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 Rose Geranium 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 Rose Geranium 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.
Does Quinine interact with any supplements?
Yes. Quinine has documented interactions with 175 supplements in our database — Rose Geranium Oil is not one of them. The Quinine interaction page linked on this page lists every one, ranked by severity.
