The bottom line No known interaction

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.

Vietnamese Coriander and Pretomanid

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 Pretomanid 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 Pretomanid, 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 Pretomanid’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 Pretomanid’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.

  • Low magnesium Worth acting on
  • High potassium Worth acting on
  • An irregular heartbeat Worth acting on mentioned in 5.3% of FDA reports for Pretomanid
  • Low sodium Worth acting on
  • Anemia Worth acting on mentioned in 11.1% of FDA reports for Pretomanid
  • Low blood sugar Worth acting on
  • Low potassium Worth acting on
  • Pancreatitis Worth acting on
  • High blood sugar Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 37 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 Pretomanid. Read the label on DailyMed › Where a percentage is shown, it is the share of 647 voluntary FDA FAERS reports for Pretomanid 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 Pretomanid Products Have a Food Rule — Vietnamese Coriander Should Not Break It

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

Recommended Dosage Pretomanid Tablets must be administered in combination with bedaquiline and linezolid with food [see Clinical Pharmacology (12.3) ] .

From the Dosage and Administration section of the FDA label we read for Pretomanid — 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 Pretomanid page

“Pretomanid is reserved for highly drug-resistant tuberculosis, and it can stress the liver and lengthen the heart's QT interval, so the supplements on this page deserve genuine care. Ten of the 143 ingredients on file carry a major rating, and nearly all of those either compound the liver risk (alcohol in beer or wine is the plainest e…”

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.
