The bottom line No known interaction

We found no known interaction between Japanese Apricot and Orlistat 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.

Japanese Apricot and Orlistat

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 Orlistat 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 Orlistat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Orlistat is filed under 2 classifications — including oral 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 Orlistat’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

What Japanese Apricot Itself Has Been Linked To

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

  • Constipation Additional detail

    “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.”

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

This page covers Japanese Apricot only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Orlistat page lists 18 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Fish Oil (moderate) and Glucomannan (moderate).

From our pharmacist’s overview on the Orlistat page

“People who take Orlistat (Xenical, Alli) for weight loss often browse the very supplement aisle where fiber products and fish oil sit, and both show up on this page, so it deserves genuine attention before you mix anything in.

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.
