No Known Interaction
The bottom line No known interaction

We found no known interaction between Madder and Goserelin 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 Goserelin

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 Goserelin 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 Goserelin, 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 Madder Itself Has Been Linked To

This is not an interaction — nothing below involves Goserelin. It is the side-effect record for Madder on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Madder, this list is the first place to look.

  • Sweating Additional detail

Everything above comes from the Natural Medicines adverse-effect record for Madder — expand a row for the licensed statement it rests on. We haven’t matched Goserelin to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Goserelin.

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.

From our Madder monograph — the full record covers uses, side effects and every documented interaction.

About Goserelin Implant

What Is Goserelin Implant Used For?

Brand name: Zoladex

  • Goserelin implant is used in combination with radiation therapy and other medications to treat localized prostate cancer and is used alone to treat the symptoms associated with advanced prostate cancer. It is also used to treat advanced breast cancer in certain women. It is also used to manage endometriosis (a condition in which the type of tissue that lines the uterus [womb] grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms) and to help with the treatment of abnormal bleeding of the uterus. Goserelin implant is in a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.

Most-Reported Side Effects for Goserelin
