The bottom line No known interaction

We found no known interaction between Alchemilla 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.

Alchemilla 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 Alchemilla 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 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. Alchemilla has documented interactions with 1 drug class — the most serious being topical drugs (minor) — 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 Quetiapine’s Own FDA Label Lists

This is not an interaction — none of it involves Alchemilla. 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. Alchemilla’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Alchemilla side to compare — that is a limit of the record, not a statement that Alchemilla has no side effects.

How to take them

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

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

Alchemilla is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).

About Alchemilla

What is Alchemilla?

Alchemilla
  • Menstrual and women's health complaints
  • Diarrhea and digestive upset
  • Wound healing (topical)
  • Skin moisturizing (topical)
  • Mild inflammation

Alchemilla (lady's mantle) is a European herb traditionally used for digestive complaints, women's health issues, and as an astringent for skin and wounds. Solid human research is very limited, so its benefits remain largely unproven, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.

Alchemilla vulgaris · Rosaceae · Above-ground parts (leaves and flowering tops) · Tea, tincture, dried herb, capsules, topical gels and creams

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

Alchemilla: dosing

There is no well-established or standardized dose for Alchemilla, because it has not been studied enough in clinical trials. Traditional use often involves a tea made from the dried herb or a tincture, and topical products are applied to the skin.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Alchemilla and Quetiapine Together: Common Questions

Is it safe to take Alchemilla with Quetiapine?
We do not list a known interaction between Alchemilla 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 Alchemilla 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 Alchemilla 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 Alchemilla and Quetiapine combination checked?
Interactions in our licensed database are recorded against drug classes. Quetiapine is filed under 10 classifications, and Alchemilla 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 Alchemilla interact with any other medications?
Yes. Alchemilla has 198 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 — Alchemilla is not one of them. The Quetiapine interaction page linked on this page lists every one, ranked by severity.
