The bottom line No known interaction

We found no known interaction between Ground Pine and Rifapentine 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 Rifapentine states a food rule worth keeping to.

Ground Pine and Rifapentine

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 Rifapentine and Ground Pine 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 Ground Pine at all — not against Rifapentine, 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 Rifapentine’s Own FDA Label Lists

This is not an interaction — none of it involves Ground Pine. These are the most notable effects listed in the ADVERSE REACTIONS section of Rifapentine’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.

  • Thoughts of self-harm Worth acting on
  • Severe muscle breakdown Worth acting on
  • High potassium Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • Wheezing Worth acting on
  • Confusion Worth acting on

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

How to take them

Some Rifapentine Products Have a Food Rule — Ground Pine Should Not Break It

At least one FDA label for a product containing Rifapentine says to take it with food. If you take Ground Pine on an empty stomach out of habit, keep them separate — and take Rifapentine 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 Rifapentine 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 ) Take with food.

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

“Rifapentine (Priftin) treats tuberculosis and is often dosed just once or twice a week, so a single blunted dose costs more than it would with a daily pill. That is why I read this list of 64 interacting supplements as a real warning rather than routine fine print.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ground Pine 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 Ground Pine reference on this page ↓

  • 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 Ground Pine

What is Ground Pine?

  • Joint pain and gout
  • Mild fever
  • Menstrual complaints
  • Wound and skin care
  • Digestive upset

Ground Pine (Ajuga chamaepitys) is a traditional European herb used mainly for joint pain, gout, and menstrual problems, but there is very little modern scientific evidence to support these uses. Because its safety has not been well studied, it should be used cautiously, and it should be avoided in pregnancy and breastfeeding. Talk to a pharmacist or doctor before trying it.

Ajuga chamaepitys · Lamiaceae · Aerial parts (flowering tops, leaves, and stems) · Dried herb, tea/infusion, tincture, liquid extract

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

About Rifapentine

What Is Rifapentine Used For?

It is also used for latent tuberculosis infection (TB germs in the body that are not causing active disease) in people 2 years and older who are at high risk of developing TB disease. For this use it is always combined with isoniazid. Both Priftin and generic rifapentine tablets carry these uses.
