The bottom line No known interaction

We found no known interaction between Urine Therapy 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.

Urine Therapy 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 Urine Therapy 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 Urine Therapy 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 Urine Therapy. 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 › Urine Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Urine Therapy side to compare — that is a limit of the record, not a statement that Urine Therapy has no side effects.

How to take them

Some Rifapentine Products Have a Food Rule — Urine Therapy Should Not Break It

At least one FDA label for a product containing Rifapentine says to take it with food. If you take Urine Therapy 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.

Everything else you take

The most serious there right now: Activated Charcoal (major), Alkanna (moderate), Alpine Ragwort (moderate), Bacillus Coagulans (moderate) and Bacillus Subtilis (moderate).

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. Urine Therapy 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 Urine Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Urine Therapy and Rifapentine records this page draws on were last updated June 22, 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 Urine Therapy

What is Urine Therapy?

  • General wellness and detox beliefs
  • Skin conditions
  • Wound or rash care
  • Allergies
  • Cancer (alternative use)
  • Infections

Urine therapy is a practice of drinking or applying one's own urine, promoted in some traditional and alternative health circles. There is no reliable scientific evidence that it treats or prevents any disease, and drinking urine can cause harm. We do not recommend it.

Human urine (one's own) · Drinking fresh urine, skin application, gargling, eye or ear drops

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

Urine Therapy: dosing

There is no established or safe dose for urine therapy because it is not a recognized medical treatment. There are safer, evidence-based options for nearly every condition people use it for.

From our Urine Therapy monograph — the full record covers uses, side effects and every documented interaction.

About Rifapentine

What Is Rifapentine Used For?

Brand name: Priftin

Rifapentine tablets — sold as Priftin and as rifapentine tablets — are used to treat two forms of tuberculosis caused by Mycobacterium tuberculosis. For active pulmonary TB (a live TB infection in the lungs), it is approved for adults and children 12 years and older. It must always be combined with other anti-TB drugs — never taken alone.

For latent tuberculosis infection (LTBI) — where TB bacteria are in the body but not yet causing illness — it is approved for adults and children 2 years and older who are at high risk of the infection becoming active. For LTBI, it is always taken together with isoniazid, once weekly for 12 weeks. Active TB disease must be ruled out before starting LTBI treatment.

Most-Reported Side Effects for Rifapentine

From FAERS, the FDA’s public side-effect reporting system (509 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fever 66 reports
Nausea 52 reports
Fatigue 42 reports
