Drug & supplement interaction

Agaricus Mushroom + Suvorexant

Suvorexant brand name: Belsomra.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Agaricus Mushroom and Suvorexant 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Agaricus Mushroom and Suvorexant

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 Suvorexant and Agaricus 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.

Agaricus Mushroom safety at a glance

Agaricus Mushroom overall Use caution Generally tolerated as a food, but supplement safety and long-term effects are not well established.
Pregnancy Avoid Not enough safety data, so it is best to avoid supplement doses during pregnancy.
Breastfeeding Avoid Not enough safety data, so avoid supplement doses 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 Suvorexant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Suvorexant is filed under 3 classifications — cns depressants, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Agaricus Mushroom has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Suvorexant’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.

No Interaction Found — But Data Suggests Agaricus Mushroom and Suvorexant May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Diarrhea Additional detail

    Agaricus Mushroom

    “In one clinical trial, mild gastrointestinal side effects such as nausea, diarrhea, and abdominal discomfort were reported in 6 of 78 patients taking a specific agaricus powder product (Sen-Sei-Ro Powder Gold, Kyowa Wellness Co., Ltd.) 1.8-5.4 grams orally daily for 60 days.”

    Suvorexant

    Listed in the ADVERSE REACTIONS section of the FDA label for Suvorexant. Read the label on DailyMed ›

Reported for Agaricus Mushroom but not commonly for Suvorexant: stomach upset, an allergic reaction, liver problems and nausea.

Effects for Suvorexant come from the ADVERSE REACTIONS section of its FDA label; effects for Agaricus Mushroom come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 12,800 voluntary FDA FAERS reports for Suvorexant that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Suvorexant page

“People take suvorexant (Belsomra) to fall asleep, and the supplements they reach for often promise the same thing, which is exactly the trouble. Of the 195 ingredients with an interaction on file, 78 add their own sedation on top of the drug's, and that theme dominates the 9 rated major, alcohol in any form among them.”

About Agaricus Mushroom

What is Agaricus Mushroom?

  • Immune support
  • General wellness and antioxidant
  • Adjunct interest during cancer care
  • Blood sugar support
  • Cholesterol and heart health

Agaricus mushroom (often Agaricus blazei/subrufescens) is a culinary and medicinal mushroom studied mostly for possible immune and antioxidant effects. The human evidence is limited and not strong enough to recommend it for treating any disease. If you want to try it, talk with your pharmacist or doctor first, especially if you have a health condition or take other medicines.

Agaricus subrufescens · Agaricaceae · Fruiting body (mushroom), sometimes mycelium · Capsules, tablets, powders, dried mushroom, liquid extracts, teas

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

Agaricus Mushroom: dosing

There is no established standard dose for Agaricus mushroom supplements. Studies have used different products and amounts, so it is hard to recommend one specific dose.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount. Choosing products from reputable companies that test for purity is wise, since supplements are not tightly regulated.

Taking Agaricus Mushroom and Suvorexant Together: Common Questions

Is it safe to take Agaricus Mushroom with Suvorexant?
We do not list a known interaction between Agaricus Mushroom and Suvorexant. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Agaricus Mushroom and Suvorexant have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Agaricus Mushroom and Suvorexant combination checked?
Interactions in our licensed database are recorded against drug classes. Suvorexant is filed under 3 classifications, and Agaricus Mushroom has documented interactions with 1 drug class — none of Suvorexant's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Agaricus Mushroom interact with any other medications?
Yes. Agaricus Mushroom has 86 documented drug interactions in our database — Suvorexant is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Suvorexant interact with any supplements?
Yes. Suvorexant has documented interactions with 195 supplements in our database — Agaricus Mushroom is not one of them. The Suvorexant interaction page linked on this page lists every one, ranked by severity.
