Drug & supplement interaction

Japanese Apricot + Nadolol

Nadolol brand names: Corgard, Nadolol.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Japanese Apricot and Nadolol 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.

Japanese Apricot and Nadolol

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 Nadolol and Japanese Apricot 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.

Japanese Apricot safety at a glance

Japanese Apricot overall Use caution Generally considered safe as a food, but concentrated supplement evidence is limited and quality varies.
Pregnancy Use caution Food amounts are likely fine, but concentrated extracts have not been well studied; use caution and ask your doctor.
Breastfeeding Use caution Little safety data exists for supplement-strength products, so caution is advised.

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

How we checked

Why No Interaction Is Listed for Nadolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nadolol is filed under 5 classifications — including beta-blockers, antihypertensive drugs, seizure threshold lowering drugs. Japanese Apricot has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antidiabetes drugs (moderate) — and none of Nadolol’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

No Interaction Found — But Data Suggests Japanese Apricot and Nadolol 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.

  • Constipation Additional detail

    Japanese Apricot

    “Orally, Japanese apricot dried fruit extract seems to be well tolerated. Side effects reported in clinical research include gastric intolerance. Diluted Japanese apricot juice concentrate may cause constipation. Allergies to Japanese apricot are rare. The raw fruit of Japanese apricot is thought to be toxic due to the cyanogenic glycosides prunasin and amygdalin.”

    Nadolol

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

Effects for Nadolol come from the ADVERSE REACTIONS section of its FDA label; effects for Japanese Apricot come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,530 voluntary FDA FAERS reports for Nadolol 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.

Overlapping uses

What Nadolol Is Prescribed For, and What Japanese Apricot Has Been Studied For

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

Nadolol is prescribed for: Nadolol tablets are used for two main conditions: high blood pressure (hypertension) and angina pectoris (ongoing chest pain caused by reduced blood flow to the heart). Lowering high blood pressure reduces the risk of stroke and heart attack. For high blood pressure, nadolol may be prescribed on its own or combined with other blood pressure medications, especially thiazide-type diuretics (water pills). For angina, it is used for long-term management to help reduce how often chest pain occurs.

Japanese Apricot has been studied for:

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

    Japanese Apricot for hypertension

    Preliminary clinical research shows that taking Japanese apricot polyphenols 800 mg daily for 12 weeks does not reduce blood pressure when compared to placebo in patients with mild to moderate hypertension. A larger study is needed in order to confirm these findings.

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 Nadolol on your own; if you are taking Japanese Apricot for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Nadolol

This page covers Japanese Apricot only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nadolol page lists 145 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), Green Tea (major) and Indian Snakeroot (major).

By severity: 6 major · 119 moderate · 20 minor.

From our pharmacist’s overview on the Nadolol page

“If you take nadolol (Corgard) for blood pressure, angina, or heart rhythm, treat this list with real care, and green tea is the surprise at the top. In a clinical study, green tea cut nadolol blood levels by roughly 85 percent, which can quietly leave you undertreated.”

About Japanese Apricot

What is Japanese Apricot?

  • Digestive upset
  • Fatigue and general wellness
  • Sore throat and cough
  • Antimicrobial support
  • Liver and detox support (traditional)

Japanese Apricot (Prunus mume) is a tart fruit used widely in East Asian foods and traditional medicine, often as pickled umeboshi or a concentrated extract. It has a long history of culinary and folk use, but high-quality human studies are limited, so most health claims remain unproven. The processed fruit is generally well tolerated as a food, but talk to a pharmacist or doctor before using concentrated supplements.

Prunus mume · Rosaceae · Fruit (often unripe, smoked, or processed into extracts) · Pickled fruit (umeboshi), concentrated fruit extract, paste, juice, syrup, capsules, tea

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

Japanese Apricot: dosing

There is no well-established standard dose for Japanese Apricot supplements. The amount varies widely depending on the form, whether it is a food (like umeboshi), a syrup, a paste, or a concentrated extract.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Japanese Apricot and Nadolol Together: Common Questions

Is it safe to take Japanese Apricot with Nadolol?
We do not list a known interaction between Japanese Apricot and Nadolol. 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 Japanese Apricot and Nadolol 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.
Are Japanese Apricot and Nadolol used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Japanese Apricot in each. That is a conversation for your prescriber, especially if Nadolol is being adjusted to a target.
How was the Japanese Apricot and Nadolol combination checked?
Interactions in our licensed database are recorded against drug classes. Nadolol is filed under 5 classifications, and Japanese Apricot has documented interactions with 2 drug classes — none of Nadolol'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 Japanese Apricot interact with any other medications?
Yes. Japanese Apricot has 208 documented drug interactions in our database — Nadolol 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 Nadolol interact with any supplements?
Yes. Nadolol has documented interactions with 145 supplements in our database — Japanese Apricot is not one of them. The Nadolol interaction page linked on this page lists every one, ranked by severity.
