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

We found no known interaction between Honeysuckle 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.

Honeysuckle 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 Honeysuckle 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.

Honeysuckle safety at a glance

Honeysuckle overall Use caution Often used as a tea with few reported problems, but high-quality safety data in humans is limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

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. Honeysuckle has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (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

What Honeysuckle Itself Has Been Linked To

This is not an interaction — nothing below involves Quetiapine. It is the side-effect record for Honeysuckle on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Honeysuckle, this list is the first place to look.

  • A skin rash Additional detail

    “Topically, applying honeysuckle to the skin has been associated with contact dermatitis in a case report. Orally, a case of biopsy-confirmed allergic drug eruption is reported in a young adult male after taking honeysuckle granules 30 grams over a 24-hour period. Symptoms resolved with discontinuation of honeysuckle and 2-weeks of antihistamine and glucocorticoid therapy.”

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

How to take them

Some Quetiapine Products Have a Food Rule — Honeysuckle Should Not Break It

At least one FDA label for a product containing Quetiapine says to take it on an empty stomach. Most supplements — Honeysuckle 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 Honeysuckle 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. See the Quetiapine 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 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 Honeysuckle

What is Honeysuckle?

  • Colds and sore throat
  • Fever
  • Inflammation
  • Skin rashes and sores
  • Digestive upset

Honeysuckle, especially Japanese honeysuckle flower (Lonicera japonica), is a staple of traditional Chinese medicine used mainly for colds, sore throat, and inflammation. Modern human evidence for these uses is limited, so it should be seen as a traditional remedy rather than a proven treatment. It is generally well tolerated as a tea, but talk to your pharmacist or doctor before using it, especially if you are pregnant, nursing, or taking other medicines.

Lonicera japonica · Caprifoliaceae · Flowers (flower buds), and sometimes stems and leaves · Tea, dried flower buds, capsules, tinctures, topical preparations, and combination herbal formulas

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

Honeysuckle: dosing

There is no standard, well-established dose for honeysuckle. The right amount depends on the form (tea, capsule, tincture) and the specific product.The safest approach is to follow the directions on the product label and not take more than recommended.

Taking Honeysuckle and Quetiapine Together: Common Questions

Is it safe to take Honeysuckle with Quetiapine?
We do not list a known interaction between Honeysuckle 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.
Should I take Honeysuckle 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 Honeysuckle 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 Honeysuckle and Quetiapine combination checked?
Interactions in our licensed database are recorded against drug classes. Quetiapine is filed under 10 classifications, and Honeysuckle has documented interactions with 1 drug class — 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 Honeysuckle interact with any other medications?
Yes. Honeysuckle has 122 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 — Honeysuckle is not one of them. The Quetiapine interaction page linked on this page lists every one, ranked by severity.
