Drug & supplement interaction

Limonene + Quetiapine

Quetiapine brand names: Seroquel, Dopaquel.

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 Limonene and Quetiapine 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 Quetiapine 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.

Limonene and Quetiapine

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 Quetiapine and Limonene 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.

Limonene safety at a glance

Limonene overall Use caution Generally well tolerated in food amounts, but human safety data for high-dose supplements is limited.
Pregnancy Avoid Not enough safety data exists for supplement doses, so it is best avoided.
Breastfeeding Likely Safe When consumed in amounts commonly found in foods. Limonene has Generally Recognized As Safe (GRAS) status in the US. There is insufficient reliable information... Read the full breastfeeding detail

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Quetiapine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Quetiapine is filed under 10 classifications — including antipsychotic drugs, qt interval-prolonging drugs, serotonergic drugs. Limonene has documented interactions with 5 drug classes — the most serious being cytochrome p450 2c19 (cyp2c19) inducers (moderate), cytochrome p450 2c19 (cyp2c19) inhibitors (moderate) and cytochrome p450 2c9 (cyp2c9) inducers (moderate) — and none of Quetiapine’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

No Interaction Found — But Data Suggests Limonene and Quetiapine May Share Several of the Same Side Effects

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.

  • Diarrhea / Vomiting / Nausea Additional detail

    Limonene

    “Orally, limonene is generally well tolerated. It can cause nausea, vomiting, and diarrhea. Topically, limonene can cause contact dermatitis. Observational research has found that increased exposure to ambient air limonene from household cleaning products is associated with wheezing and asthma, particularly in children.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Quetiapine. Read the label on DailyMed ›

Reported for Limonene but not commonly for Quetiapine: a skin rash and wheezing.

Effects for Quetiapine come from the ADVERSE REACTIONS section of its FDA label; effects for Limonene come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 188,604 voluntary FDA FAERS reports for Quetiapine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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 Quetiapine Products Have a Food Rule — Limonene Should Not Break It

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

It is recommended that SEROQUEL XR be taken without food or with a light meal (approximately 300 calories) [see Clinical Pharmacology (12.3) ].

From the Dosage and Administration section of the FDA label we read for Quetiapine — 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 Quetiapine page

“Quetiapine (Seroquel) treats schizophrenia and bipolar disorder, illnesses where an unplanned swing in the drug's blood level has real consequences, and that is why these 199 supplement interactions deserve a careful read rather than a shrug. Most of the risk runs through CYP3A4, the liver enzyme that clears quetiapine: grapefruit bloc…”

About Limonene

What is Limonene?

  • Heartburn and acid reflux
  • Digestive upset
  • Stress and mood support
  • Antioxidant support
  • General wellness

Limonene is a natural compound found in the peel of citrus fruits like oranges and lemons, and it is used as a flavoring agent and dietary supplement. People take it for heartburn, digestion, and general wellness, but solid human evidence is limited. It is generally well tolerated in food amounts, but talk with your pharmacist or doctor before using concentrated supplements.

Essential oil from citrus peel (the natural source of limonene) · Softgel capsules, oils, flavoring agent in foods, aromatherapy oils

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

Limonene: dosing

There is no official or well-established dose for limonene supplements. Studies have used a wide range of amounts, and products vary a lot in strength.The best advice is to follow the directions on the product label and not exceed them.

About Quetiapine

What Is Quetiapine Used For?

Taking Limonene and Quetiapine Together: Common Questions

Is it safe to take Limonene with Quetiapine?
We do not list a known interaction between Limonene and Quetiapine. 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 Limonene and Quetiapine have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Limonene and Quetiapine at the same time of day?
At least one FDA label for a product containing Quetiapine 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 Quetiapine on its own and move Limonene 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 Limonene and Quetiapine combination checked?
Interactions in our licensed database are recorded against drug classes. Quetiapine is filed under 10 classifications, and Limonene has documented interactions with 5 drug classes — none of Quetiapine'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 Limonene interact with any other medications?
Yes. Limonene has 229 documented drug interactions in our database — Quetiapine 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 Quetiapine interact with any supplements?
Yes. Quetiapine has documented interactions with 199 supplements in our database — Limonene is not one of them. The Quetiapine interaction page linked on this page lists every one, ranked by severity.
