Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Vietnamese Coriander 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.

Vietnamese Coriander 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 Vietnamese Coriander 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 Vietnamese Coriander 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.

What Penicillamine’s Own FDA Label Lists

This is not an interaction — none of it involves Vietnamese Coriander. These are the most notable effects listed in the ADVERSE REACTIONS section of Penicillamine’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Muscle weakness Worth acting on
  • Bleeding in the gut Worth acting on
  • Low blood sugar Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Wheezing Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on

Showing the 10 most notable of 26 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 Penicillamine. Read the label on DailyMed › Where a percentage is shown, it is the share of 917 voluntary FDA FAERS reports for Penicillamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Vietnamese Coriander’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Vietnamese Coriander side to compare — that is a limit of the record, not a statement that Vietnamese Coriander has no side effects.

How to take them

Some Penicillamine Products Have a Food Rule — Vietnamese Coriander Should Not Break It

At least one FDA label for a product containing Penicillamine says to take it on an empty stomach. Most supplements — Vietnamese Coriander 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 Vietnamese Coriander 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.

About Vietnamese Coriander

What is Vietnamese Coriander?

  • Flavoring food
  • Digestive upset
  • Antimicrobial uses
  • Reducing sexual desire (traditional)
  • Skin and wound care (traditional)

Vietnamese coriander (rau ram) is a fragrant Southeast Asian culinary herb traditionally used for digestion and as an antimicrobial. There is very little human research to support its medicinal uses, so it is best thought of as a flavorful food rather than a proven remedy. Pregnant and breastfeeding people should avoid medicinal amounts, and anyone considering it as a supplement should check with a pharmacist or doctor.

Persicaria odorata · Polygonaceae · Leaves and stems · Fresh leaves (culinary herb), dried leaves, tea, essential oil

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

Vietnamese Coriander: dosing

There is no established or standardized medicinal dose for Vietnamese coriander. It is most often used simply as a fresh culinary herb, added to dishes to taste.If you choose to use a tea or supplement product, follow the directions on the label and do not exceed the recommended amount.

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.

Taking Vietnamese Coriander and Penicillamine Together: Common Questions

Is it safe to take Vietnamese Coriander with Penicillamine?
We do not list a known interaction between Vietnamese Coriander and Penicillamine. 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.
Should I take Vietnamese Coriander and Penicillamine at the same time of day?
At least one FDA label for a product containing Penicillamine says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Penicillamine on its own and move Vietnamese Coriander to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Penicillamine interact with any supplements?
Yes. Penicillamine has documented interactions with 26 supplements in our database — Vietnamese Coriander is not one of them. The Penicillamine interaction page linked on this page lists every one, ranked by severity.
