The bottom line No known interaction

We found no known interaction between Pygeum and Olmesartan Medoxomil 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.

Pygeum and Olmesartan Medoxomil

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 Olmesartan Medoxomil and Pygeum 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Pygeum at all — not against Olmesartan Medoxomil, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Pygeum safety at a glance

Pygeum overall Use caution Generally well tolerated short-term, but quality and long-term safety data are limited.
Pregnancy Avoid Pygeum is used for men's prostate health and has no established safe use in pregnancy.
Breastfeeding Avoid There is not enough safety information, so it is best avoided while breastfeeding.

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

What to actually watch for

What Pygeum Itself Has Been Linked To

This is not an interaction — nothing below involves Olmesartan Medoxomil. It is the side-effect record for Pygeum on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Pygeum, this list is the first place to look.

  • Stomach pain / Nausea Additional detail

    “Orally, pygeum has been associated with nausea and abdominal pain in some clinical research. However, the rate of these events were similar to placebo.”

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

From our pharmacist’s overview on the Olmesartan Medoxomil page

“Olmesartan medoxomil (Benicar) lowers blood pressure by relaxing blood vessels, and nearly everything on this page, 119 of the 136 ingredients, pulls on that same lever, deepening the drop or working against it. Four entries rate major, which is why this list deserves genuine care rather than a quick skim.”

About Pygeum

What is Pygeum?

  • Benign prostatic hyperplasia (BPH) symptoms
  • Urinary symptoms in men
  • Prostate health
  • Inflammation

Pygeum is an extract from the bark of the African cherry tree that is most often used to ease urinary symptoms linked to an enlarged prostate. Some studies suggest modest benefit for these symptoms, but the research is limited and not high quality. Talk with your doctor or pharmacist before using it, especially since urinary symptoms can have serious causes.

Prunus africana · Rosaceae · Bark · Capsules, tablets, liquid extracts

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

Pygeum: dosing

There is no single official or standardized dose of pygeum. Do not assume that taking more will work better, and let your healthcare provider know you are using it so they can monitor your symptoms.

From our Pygeum monograph — the full record covers uses, side effects and every documented interaction.
