The bottom line No known interaction

We found no known interaction between Japanese Persimmon and Ferric Citrate 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 Ferric Citrate states a food rule worth keeping to.

Japanese Persimmon and Ferric Citrate

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 Ferric Citrate and Japanese Persimmon 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 Persimmon safety at a glance

Japanese Persimmon overall Use caution The fruit is safe as food, but eating large amounts of unripe persimmons may cause hard masses (bezoars) in the stomach.
Pregnancy Use caution Eating the fruit as food is likely fine, but concentrated leaf or calyx supplements have not been well studied, so avoid those.
Breastfeeding Use caution The fruit as food is likely fine, but there is not enough data on concentrated supplements, so use caution.

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

How we checked

Why No Interaction Is Listed for Ferric Citrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ferric Citrate is filed under a single classification — oral drugs. Japanese Persimmon has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Ferric Citrate’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 Ferric Citrate’s Own FDA Label Lists

This is not an interaction — none of it involves Japanese Persimmon. These are the most notable effects listed in the ADVERSE REACTIONS section of Ferric Citrate’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. 3 of them are worth acting on rather than waiting out — marked below.

  • High potassium Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Cough
  • Constipation
  • Stomach pain
  • Diarrhea
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Ferric Citrate. Read the label on DailyMed › Japanese Persimmon’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Japanese Persimmon side to compare — that is a limit of the record, not a statement that Japanese Persimmon has no side effects.

How to take them

Some Ferric Citrate Products Have a Food Rule — Japanese Persimmon Should Not Break It

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

( 2.2 ) 2.1 Dosage for Hyperphosphatemia in Chronic Kidney Disease on Dialysis The recommended starting dose is 2 tablets, swallowed whole, 3 times per day with meals.

From the Dosage and Administration section of the FDA label we read for Ferric Citrate — 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.

From our pharmacist’s overview on the Ferric Citrate page

“Ferric citrate (Auryxia) does its work in the gut, binding dietary phosphate in kidney disease or supplying iron, and all 17 supplements on this list can interfere with how oral medicines get absorbed. That is worth real caution, starting with the single major-rated entry, activated charcoal, which adsorbs many drugs directly and can m…”

About Japanese Persimmon

What is Japanese Persimmon?

  • High blood pressure
  • Cough and hiccups (traditional use)
  • Antioxidant support
  • Digestive health and fiber
  • Skin and general wellness

Japanese persimmon is a nutritious fruit rich in fiber, vitamins, and antioxidant plant compounds, and its leaves and calyx are used in traditional medicine. While eating the fruit as food is generally safe and healthy, the evidence for concentrated supplements or leaf extracts treating specific conditions is limited. Talk to your pharmacist or doctor before using persimmon products medicinally.

Diospyros kaki · Ebenaceae · Fruit, leaves, and the dried fruit calyx (persimmon stalk) · Fresh or dried fruit, tea (often from leaves), powder, capsules, and extracts

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

Japanese Persimmon: dosing

There is no standardized or proven medicinal dose for persimmon supplements. As a food, persimmon is simply eaten as a fresh or dried fruit. For leaf teas, powders, and capsules, the right amount varies by product.If you choose to use a persimmon supplement, follow the directions on the product label and do not exceed the recommended amount.

Taking Japanese Persimmon and Ferric Citrate Together: Common Questions

Is it safe to take Japanese Persimmon with Ferric Citrate?

If you take Japanese Persimmon on an empty stomach out of habit, keep them separate and take Ferric Citrate with a meal where the label says to.

Ferric Citrate is filed under 1 classification, and Japanese Persimmon has documented interactions with 2 drug classes — none of Ferric Citrate'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.
