Bitter Yam + Mifepristone
Mifepristone brand names: Mifeprex, Korlym.
We found no known interaction between Bitter Yam and Mifepristone 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.
Bitter Yam and Mifepristone
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 Mifepristone and Bitter Yam 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.
Bitter Yam safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Mifepristone
Interactions in our licensed database are recorded against drug classes, not just single drug names. Mifepristone is filed under 4 classifications — including qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates. Bitter Yam has documented interactions with 1 drug class — the most serious being digoxin (lanoxin) (moderate) — and none of Mifepristone’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 Mifepristone Is Prescribed For, and What Bitter Yam Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Mifepristone is a prescription medicine with approved uses on its FDA label. Bitter Yam is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Mifepristone is prescribed for: Korlym is prescribed for adults with endogenous Cushing's syndrome — a condition where the body produces too much cortisol — who also have type 2 diabetes or trouble controlling blood sugar. It works to bring those blood sugar levels under control. It is only for blood sugar problems that are directly caused by Cushing's syndrome. It should not be used to treat ordinary type 2 diabetes unrelated to this condition.

Diabetes studied, not established Bitter Yam has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Bitter Yam for diabetes
Although there has been interest in using oral bitter yam for diabetes, there is insufficient reliable information about the clinical effects of bitter yam for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Mifepristone on your own; if you are taking Bitter Yam for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.
See Every Supplement That Interacts With Mifepristone
This page covers Bitter Yam only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mifepristone page lists 151 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).
By severity: 8 major · 104 moderate · 39 minor.
From our pharmacist’s overview on the Mifepristone page
“Mifepristone is a drug where a failed dose has real consequences, whether it is Mifeprex used to end an early pregnancy or Korlym taken daily for Cushing's syndrome, so its interaction list deserves genuine respect. Most of the 151 ingredients on file act on the CYP3A4 enzyme that clears the drug, pushing its blood level up or dragging…”

About Bitter Yam
What is Bitter Yam?
- Blood sugar support
- Digestive complaints
- Traditional food source
- Wound and skin care (folk use)
Bitter yam is a wild African yam used traditionally as both food and folk medicine, often for blood sugar and digestion. Scientific evidence in humans is very limited, and some bitter yam species can be toxic if not properly prepared. Talk to a pharmacist or doctor before using it as a supplement.
Dioscorea dumetorum · Dioscoreaceae · Tuber (root) · Cooked tuber, dried powder, traditional preparations
An interaction check asks whether these two react with each other — it does not ask whether Bitter Yam is a good idea for someone in your situation. Here is what our Bitter Yam record says about it on its own.
Bitter Yam: dosing
There is no established, standardized dose of bitter yam as a supplement. Traditional use varies widely and depends on how the tuber is prepared.If you choose to use a commercial product, follow the directions on the label and do not take more than recommended.
