Drug & supplement interaction

Yellow Dock + Flibanserin

Flibanserin brand name: Addyi.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Yellow Dock and Flibanserin 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 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.

Yellow Dock and Flibanserin

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 Flibanserin and Yellow Dock 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 Flibanserin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Flibanserin is filed under 5 classifications — including cytochrome p450 2c19 (cyp2c19) substrates, cns depressants, cytochrome p450 3a4 (cyp3a4) substrates. Yellow Dock has documented interactions with 3 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (major) and warfarin (coumadin) (moderate) — and none of Flibanserin’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 Yellow Dock and Flibanserin 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.

Reported for Yellow Dock but not commonly for Flibanserin: stomach pain, a low platelet count, kidney problems and kidney stones.

Effects for Flibanserin come from the ADVERSE REACTIONS section of its FDA label; effects for Yellow Dock come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,994 voluntary FDA FAERS reports for Flibanserin 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.

About Yellow Dock

What is Yellow Dock?

  • Constipation
  • Digestive support
  • Skin conditions
  • Iron-deficiency or 'blood-building' tonic
  • Liver and detox support

Yellow dock is a traditional herb used mostly as a mild laxative and a digestive and skin tonic. Good-quality human studies are lacking, so its benefits are largely unproven, and its naturally occurring oxalates and anthraquinones mean it should be used cautiously and not long-term.

Rumex crispus · Polygonaceae · Root (rhizome); leaves are sometimes used · Capsules, tinctures, liquid extracts, dried root for tea, and sometimes topical ointments

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

Yellow Dock: dosing

There is no official or standardized dose for yellow dock, and product strengths vary widely between teas, tinctures, and capsules. Because of this, the safest approach is to follow the directions on the product label and not exceed them.Use it for the shortest time needed rather than as a long-term daily supplement.

Taking Yellow Dock and Flibanserin Together: Common Questions

Is it safe to take Yellow Dock with Flibanserin?
We do not list a known interaction between Yellow Dock and Flibanserin. 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 Yellow Dock and Flibanserin have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
How was the Yellow Dock and Flibanserin combination checked?
Interactions in our licensed database are recorded against drug classes. Flibanserin is filed under 5 classifications, and Yellow Dock has documented interactions with 3 drug classes — none of Flibanserin'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 Yellow Dock interact with any other medications?
Yes. Yellow Dock has 78 documented drug interactions in our database — Flibanserin 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 Flibanserin interact with any supplements?
Yes. Flibanserin has documented interactions with 199 supplements in our database — Yellow Dock is not one of them. The Flibanserin interaction page linked on this page lists every one, ranked by severity.
