Madder + Docetaxel
Docetaxel brand name: Taxotere.
We found no known interaction between Madder and Docetaxel 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.
Madder and Docetaxel
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 Docetaxel and Madder 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 Madder at all — not against Docetaxel, 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.

See Every Supplement That Interacts With Docetaxel
This page covers Madder only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Docetaxel page lists 121 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate), Adrafinil (moderate) and African Wild Potato (moderate).
By severity: 2 major · 87 moderate · 32 minor.
From our pharmacist’s overview on the Docetaxel page
“Grapefruit is the first thing I would take off the menu during docetaxel (Taxotere) chemotherapy. It blocks CYP3A4, the liver enzyme that clears docetaxel, and higher levels of a chemotherapy drug mean harsher side effects, not better results.”

About Madder
What is Madder?
- Kidney and bladder stones
- Urinary tract complaints
- Menstrual problems
- Natural red dye for fabric
- Traditional digestive remedy
Madder is a plant whose root has long been used as a red dye and in traditional medicine, mostly for kidney and urinary problems. There is very little reliable human evidence that it works, and some of its compounds have raised concerns about possible cancer-causing effects, so it is generally not recommended for use as a supplement. Talk to your pharmacist or doctor before considering it.
Rubia tinctorum · Rubiaceae · Root · Dried root, powder, capsules, tea, extracts, and natural dye
An interaction check asks whether these two react with each other — it does not ask whether Madder is a good idea for someone in your situation. Here is what our Madder record says about it on its own.
Madder: dosing
There is no established safe or effective dose of madder for any health condition. In general, we do not recommend taking madder root internally. Its safer, well-established use is as a fabric dye rather than as a supplement.

About Docetaxel Injection
What Is Docetaxel Injection Used For?

Docetaxel Injection is used to treat a number of serious cancers.
