The bottom line No known interaction

We found no known interaction between Maitake Mushroom and Roxithromycin in our sources.

Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Maitake Mushroom and Roxithromycin

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 Roxithromycin and Maitake 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.

Maitake Mushroom safety at a glance

Maitake Mushroom overall Use caution Generally well tolerated as food, but supplement safety has not been fully studied.
Pregnancy Avoid Not enough safety data, so concentrated supplements should be avoided during pregnancy.
Breastfeeding Avoid Not enough safety data, so concentrated supplements should be avoided while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Roxithromycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Roxithromycin is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Maitake Mushroom has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and warfarin (coumadin) (moderate) — and none of Roxithromycin’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.

Everything above comes from the Natural Medicines adverse-effect record for Maitake Mushroom — expand a row for the licensed statement it rests on. We haven’t matched Roxithromycin 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 Roxithromycin.

See Every Supplement That Interacts With Roxithromycin

This page covers Maitake Mushroom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Roxithromycin page lists 30 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Cannabidiol (cbd) (moderate), Cannabinol (cbn) (moderate) and Cannabis (moderate).

By severity: 1 major · 19 moderate · 10 minor.

From our pharmacist’s overview on the Roxithromycin page

“If you take roxithromycin, an antibiotic prescribed for chest, throat, and skin infections, the entry to sort out first is activated charcoal, the only major-rated interaction among the 30 supplements on file. Charcoal binds medicines in the gut and can pull roxithromycin levels low enough to undercut treatment of the infection itself.”

About Maitake Mushroom

What is Maitake Mushroom?

Maitake Mushroom
  • Immune support
  • Blood sugar support in diabetes
  • High blood pressure
  • High cholesterol
  • General wellness and antioxidant support

Maitake is an edible mushroom long used as food and in traditional Japanese medicine, and it is being studied for possible immune, blood sugar, and blood pressure effects. The human evidence is still limited and not strong enough to recommend it as a treatment. It is generally well tolerated as food, but talk to your pharmacist or doctor before using concentrated supplements.

Grifola frondosa · Meripilaceae · Fruiting body (mushroom) and mycelium; also purified extracts such as the 'D-fraction' · Capsules, tablets, powders, liquid extracts (D-fraction/SX-fraction), and whole mushroom used as food

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

Maitake Mushroom: dosing

There is no official, well-established dose for maitake supplements. Products vary widely in strength and in how they are prepared, including whole mushroom powders and standardized extracts like the D-fraction.The best approach is to follow the directions on the product label and to choose products from reputable brands.
