The bottom line No known interaction

We found no known interaction between Poria Mushroom and Nilutamide 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.

Interaction report

Poria Mushroom and Nilutamide

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 Nilutamide and Poria Mushroom 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.

Poria Mushroom safety at a glance

Poria Mushroom overall Use caution Generally well tolerated in traditional use, but human safety data are limited.

Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.

Breastfeeding Avoid No reliable safety data while breastfeeding, so avoidance is recommended.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Nilutamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nilutamide is filed under 2 classifications — cytochrome p450 2c19 (cyp2c19) substrates, oral drugs. Poria Mushroom has documented interactions with 3 drug classes — the most serious being anticholinergic drugs (moderate), cholinergic drugs (moderate) and cns depressants (moderate) — and none of Nilutamide’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.

Keep it in perspective

What to actually watch for

What Poria Mushroom Itself Has Been Linked To

This is not an interaction — nothing below involves Nilutamide. It is the side-effect record for Poria Mushroom on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Poria Mushroom, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Wheezing / An allergic reaction Worth acting on Additional detail

Recorded for Poria Mushroom in the same Natural Medicines adverse-effect record shown under Wheezing / An allergic reaction above.

Everything above comes from the Natural Medicines adverse-effect record for Poria Mushroom — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Nilutamide’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Nilutamide column appears here.

Overlapping uses

What Nilutamide Is Prescribed For, and What Poria Mushroom Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Nilutamide is a prescription medicine with approved uses on its FDA label. Poria Mushroom is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Nilutamide is prescribed for: Nilutamide tablets are used together with surgical castration (removal of the testicles) to treat metastatic prostate cancer — prostate cancer that has spread to other parts of the body (Stage D2). It is not used alone; it works as part of this combined treatment approach. For the best results, treatment with nilutamide should begin on the same day as surgical castration, or the day after.

Poria Mushroom has been studied for:

Cancer studied, not established Poria Mushroom has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Poria Mushroom for cancer

Although there is interest in using oral poria mushroom for cancer, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.

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 Nilutamide on your own; if you are taking Poria Mushroom for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Nilutamide

This page covers Poria Mushroom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nilutamide page lists 50 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Artichoke (moderate), Bacopa (moderate) and Baikal Skullcap (moderate).

By severity: 1 major · 36 moderate · 13 minor.

From our pharmacist’s overview on the Nilutamide page

“Nilutamide (Nilandron) treats prostate cancer, so a supplement that weakens it or distorts its levels carries real weight, and this list warrants genuine care rather than a quick skim. The lone major-rated entry is activated charcoal, which can bind the drug in the gut and cut how much actually reaches the blood, a serious problem for…”

About Poria Mushroom

What is Poria Mushroom?

Fluid retention and swelling
Digestive complaints
Sleep and calming support
General wellness and immune support
Urinary support

Poria mushroom (Fu Ling) is a fungus long used in Traditional Chinese Medicine, mainly as a mild diuretic and digestive and calming aid. Modern scientific evidence in humans is very limited, so its benefits are not well proven. It is generally considered well tolerated, but talk with your pharmacist or doctor before using it, and avoid it in pregnancy and breastfeeding due to a lack of safety data.

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

Poria Mushroom: dosing

There is no official, standardized dose of poria mushroom for any health condition. Do not exceed the recommended amount, and start low to see how you tolerate it.

Are Poria Mushroom and Nilutamide used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

Nilutamide is filed under 2 classifications, and Poria Mushroom has documented interactions with 3 drug classes — none of Nilutamide's classifications are among them.
