Interaction report

Japanese Persimmon and Mepolizumab

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 Mepolizumab 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.

Showing the 10 most notable of 12 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 Mepolizumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 49,399 voluntary FDA FAERS reports for Mepolizumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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.

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.
