Kampo Medicine + Penicillamine
Penicillamine brand names: Cuprimine, Depen Titratable.
We found no known interaction between Kampo Medicine and Penicillamine 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 Penicillamine states a food rule worth keeping to.
Kampo Medicine and Penicillamine
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 Penicillamine and Kampo Medicine 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Kampo Medicine at all — not against Penicillamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.
Kampo Medicine safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Penicillamine Products Have a Food Rule — Kampo Medicine Should Not Break It
At least one FDA label for a product containing Penicillamine says to take it on an empty stomach. Most supplements — Kampo Medicine included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Penicillamine on its own and move Kampo Medicine to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Penicillamine 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 In all patients receiving penicillamine, it is important that CUPRIMINE be given on an empty stomach, at least one hour before meals or two hours after meals, and at least one hour apart from any other drug, food, or milk.
From the Dosage and Administration section of the FDA label we read for Penicillamine — 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.

Where Kampo Medicine and Penicillamine Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

#2,671 of 2,830 medications looked up here in the last 7 days

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Kampo Medicine is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Kampo Medicine reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Kampo Medicine and Penicillamine records this page draws on were last updated June 20, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Kampo Medicine
What is Kampo Medicine?
- Digestive complaints
- Cold and flu symptoms
- Menopausal symptoms
- Fatigue and general weakness
- Constipation
- Pain and inflammation
Kampo is a traditional Japanese system of herbal medicine that uses standardized multi-herb formulas, many of which are prescribed by doctors in Japan. Some formulas have modest supportive evidence for certain conditions, but quality and strength of research vary widely. Because Kampo products combine many ingredients, talk with a pharmacist or doctor before using them, especially if you take other medicines or have a health condition.
Roots, rhizomes, bark, leaves, flowers, fruits, seeds, and minerals depending on the formula · Granules, powders, decoctions (teas), tablets, and capsules
An interaction check asks whether these two react with each other — it does not ask whether Kampo Medicine is a good idea for someone in your situation. Here is what our Kampo Medicine record says about it on its own.
Kampo Medicine: dosing
There is no single standard dose for "Kampo medicine" because it is a whole system of many different formulas. Each formula has its own typical dosing, which can also depend on the person and the condition being treated.In Japan, doses are often based on standardized extract granules and prescribed by a clinician.

About Penicillamine
What Is Penicillamine Used For?
Brand names: Cuprimine, Depen Titratable
Penicillamine is used for three distinct conditions. It treats Wilson's disease — a rare genetic disorder in which the body accumulates dangerous levels of copper — by binding to the excess copper and helping the body remove it. It also treats cystinuria, a condition where the amino acid cystine builds up and forms painful kidney stones, by converting cystine into a more soluble form that the body can excrete more easily.
For patients with severe, active rheumatoid arthritis who have not responded adequately to conventional therapies, penicillamine (available as Aagylur, Cuprimine, Depen, and other products) may be used to help suppress disease activity and reduce joint pain, tenderness, and swelling.

Penicillamine Is Linked to Lower Levels of 5 Nutrients
Natural Medicines records Penicillamine as a medicine that can lower these. This is not an interaction with Kampo Medicine — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
