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

Nadh 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 Nadh 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 Nadh 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.

What Olmesartan Medoxomil’s Own FDA Label Lists

This is not an interaction — none of it involves Nadh. These are the most notable effects listed in the ADVERSE REACTIONS section of Olmesartan Medoxomil’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • High potassium Worth acting on
  • A heart attack Worth acting on
  • High blood sugar Worth acting on
  • Kidney problems Worth acting on mentioned in 5.5% of FDA reports for Olmesartan Medoxomil

Showing the 10 most notable of 14 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Olmesartan Medoxomil. Read the label on DailyMed › Where a percentage is shown, it is the share of 43,574 voluntary FDA FAERS reports for Olmesartan Medoxomil that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Nadh’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Nadh side to compare — that is a limit of the record, not a statement that Nadh has no side effects.

Overlapping uses

What Olmesartan Medoxomil Is Prescribed For, and What Nadh Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Olmesartan Medoxomil is a prescription medicine with approved uses on its FDA label. Nadh is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Olmesartan Medoxomil is prescribed for: Olmesartan treats high blood pressure (hypertension) in adults and in children aged 6 years and older. It can be used alone or combined with other blood pressure medicines. Lowering blood pressure reduces the risk of serious events like stroke and heart attack. It is available as Benicar and as generic olmesartan medoxomil tablets, including a combination tablet with hydrochlorothiazide.

  • Hypertension studied, not established Nadh has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Nadh for hypertension

    Although there has been interest in using oral NADH for hypertension, there is insufficient reliable information about the clinical effects of NADH for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Olmesartan Medoxomil on your own; if you are taking Nadh for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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 Nadh

What is Nadh?

  • Chronic fatigue syndrome
  • Low energy and tiredness
  • Athletic performance
  • Mental clarity and focus
  • Parkinson's disease (investigational)
  • Jet lag

NADH is the active, electron-carrying form of niacin (vitamin B3) that your body uses to make energy in cells. Some people take it as a supplement for fatigue, mental sharpness, and athletic performance, but solid human evidence is limited and mostly preliminary. It appears generally well tolerated in the short term, but talk with your pharmacist or doctor before trying it.

Not applicable (a coenzyme form of vitamin B3/niacin) · Tablets, capsules, sublingual lozenges, sometimes intravenous (clinical settings)

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

Nadh: dosing

There is no official, standardized dose of NADH. Doses used in studies have varied, and product strengths differ from brand to brand. Sublingual (under-the-tongue) forms are marketed as being better absorbed, though strong proof for this is limited.The safest approach is to follow the directions on the product label and not exceed the recommended amount. Taking it earlier in the day may help avoid sleep problems.
