Maitake Mushroom and Eprosartan

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Eprosartan

Eprosartan falls under ANTIHYPERTENSIVE DRUGS — the group Maitake Mushroom interacts with.

Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: Eprosartan (Teveten) already works to bring your blood pressure down, and maitake mushroom may nudge it down a little further. So the concern isn't that maitake blocks or changes how your body handles eprosartan. Instead, it's that two blood-pressure-lowering effects could stack on top of each other.

I want to be honest about how soft this evidence is. The worry comes mostly from animal studies, not solid human research, so it's more theoretical than proven. If your pressure dropped too low, you might feel dizzy, lightheaded, tired, or shaky, especially when standing up quickly. Enjoying maitake as food is unlikely to be a problem, but concentrated supplements are a different story. Please check with your pharmacist or doctor before adding one.

This page covers Maitake Mushroom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Eprosartan page lists 138 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Tyramine (major) and Adrafinil (moderate).

By severity: 4 major · 112 moderate · 22 minor.

From our pharmacist’s overview on the Eprosartan page

“Activated charcoal deserves the first look from anyone taking eprosartan (Teveten) for blood pressure, because it can soak up the medicine in the gut and leave less of your dose to do its job. It is one of four major-rated entries among the 138 supplements and herbs on this page, enough to warrant real wariness rather than a shrug.”

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.

About Eprosartan

What Is Eprosartan Used For?

Brand name: Teveten

  • Eprosartan is used alone or in combination with other medications to treat high blood pressure. Eprosartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.

  • High blood pressure is a common condition, and when not treated it can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
