The bottom line No known interaction

We found no known interaction between Avens 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.

Avens 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 Avens 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 Avens at all — not against Quetiapine, 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.

What Quetiapine’s Own FDA Label Lists

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

  • Mania or an unusually elevated mood Worth acting on
  • A change in thyroid levels Worth acting on
  • Thoughts of self-harm Worth acting on
  • A bowel blockage Worth acting on
  • Severe muscle breakdown Worth acting on
  • Memory problems Worth acting on
  • High blood sugar Worth acting on mentioned in 4.4% of FDA reports for Quetiapine
  • Trouble swallowing Worth acting on
  • Trouble passing urine Worth acting on
  • Low sodium Worth acting on

Showing the 10 most notable of 63 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

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

How to take them

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

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

What is Avens?

Avens
  • Diarrhea
  • Indigestion and dyspepsia
  • Gas (flatulence)
  • Sore throat and mouth rinses
  • Mild inflammation

Avens is a traditional European herb whose root and leaves are rich in tannins and have long been used as a tea for diarrhea and digestive upset. Solid human research is lacking, so its benefits are unproven. If you choose to try it, use it short-term, follow the product label, and check first with your pharmacist or doctor.

Geum urbanum · Rosaceae · Dried aerial (flowering) parts and roots · Tea (infusion), decoction, dried herb, root powder, tincture

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

Avens: dosing

There is no officially established or standardized dose for Avens. Traditional sources describe steeping a small amount of dried herb in hot water as a tea, or briefly boiling the dried root to make a decoction.Because product strengths vary widely, the safest approach is to follow the directions on the product label and not exceed them.

Taking Avens and Quetiapine Together: Common Questions

Is it safe to take Avens with Quetiapine?
We do not list a known interaction between Avens 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 Avens 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 Avens 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.
Does Quetiapine interact with any supplements?
Yes. Quetiapine has documented interactions with 199 supplements in our database — Avens is not one of them. The Quetiapine interaction page linked on this page lists every one, ranked by severity.
