Japanese Apricot + Cefaclor

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 Cefaclor 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 label for Cefaclor states a food rule worth keeping to, and 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 Cefaclor

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 Cefaclor 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 Cefaclor

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefaclor is filed under 6 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic 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 Cefaclor’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.

No Interaction Found — But Data Suggests Japanese Apricot and Cefaclor 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.”

Effects for Cefaclor come from the ADVERSE REACTIONS section of its FDA label; effects for Japanese Apricot come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Cefaclor Products Have a Food Rule — Japanese Apricot Should Not Break It

At least one FDA label for a product containing Cefaclor says to take it with food. If you take Japanese Apricot on an empty stomach out of habit, keep them separate — and take Cefaclor with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cefaclor products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

DOSAGE AND ADMINISTRATION The absorption of cefaclor extended-release tablets is enhanced when it is administered with food.

From the Dosage and Administration section of the FDA label we read for Cefaclor — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefaclor page

“The entries worth understanding before any others on this cefaclor (Ceclor) page are the kidney risks and charcoal. Cefaclor is a cephalosporin antibiotic, typically a short course for ear, sinus, throat, or skin infections, and two herbs here, Siberian cocklebur and asarabacca, can damage the kidneys on their own, so pairing either wi…”

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.

About Cefaclor

What Is Cefaclor Used For?

Brand names: Ceclor CD, Ceclor

Cefaclor treats a range of bacterial infections. Cefaclor capsules and oral suspension are used for ear infections (otitis media), lower respiratory tract infections including pneumonia, strep throat and tonsillitis, urinary tract infections (including kidney infections and bladder infections), and skin and skin structure infections.

Cefaclor extended-release tablets are approved for a narrower set of uses in adults: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin and skin structure infections. Not all formulations are approved for the same conditions, so the form matters.

Taking Japanese Apricot and Cefaclor Together: Common Questions

Is it safe to take Japanese Apricot with Cefaclor?
We do not list a known interaction between Japanese Apricot and Cefaclor. 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 Cefaclor 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.
Should I take Japanese Apricot and Cefaclor at the same time of day?
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Japanese Apricot on an empty stomach out of habit, keep them separate and take Cefaclor with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Cefaclor products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Japanese Apricot and Cefaclor combination checked?
Interactions in our licensed database are recorded against drug classes. Cefaclor is filed under 6 classifications, and Japanese Apricot has documented interactions with 2 drug classes — none of Cefaclor'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 — Cefaclor 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 Cefaclor interact with any supplements?
Yes. Cefaclor has documented interactions with 60 supplements in our database — Japanese Apricot is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
