The bottom line No known interaction

We found no known interaction between Poria Mushroom and Roxithromycin 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.

Poria 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 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 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. 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 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.

What to actually watch for

What Poria Mushroom Itself Has Been Linked To

This is not an interaction — nothing below involves Roxithromycin. 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

    “Allergic reactions have been reported rarely, including allergic rhinitis and allergic asthma (12).”

Everything above comes from the Natural Medicines adverse-effect record for Poria 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 Poria 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 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.
