Drug & supplement interaction

Pomegranate + Rifapentine

Rifapentine brand name: Priftin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Pomegranate 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, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Pomegranate 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 Pomegranate 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.

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.

Pharmacist analysis

Pomegranate (and pomegranate extract) has several potential drug interactions that should be taken into consideration.

Primarily, pomegranate can affect drugs metabolized by CYP2C9, CYP2D6, and CYP3A4 enzymes. This accounts for a very large proportion of the drug interactions associated with pomegranate.

Pomegranate also may have mild antihypertensive effects, potentially increasing the risk of adverse effects and hypotension when used with other drugs that lower blood pressure.

Although there is no interaction noted between pomegranate and the drug in question, as always, it is recommended to speak with your doctor before adding on any new medications or supplements so you can be appropraitely monitored.

How we checked

Why No Interaction Is Listed for Rifapentine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rifapentine is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inducers, cytochrome p450 3a4 (cyp3a4) inducers, antibiotic drugs. Pomegranate has documented interactions with 9 drug classes — the most serious being ace inhibitors (aceis) (moderate), antihypertensive drugs (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (moderate) — and none of Rifapentine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

Pomegranate Does Interact With Other Medications

What to actually watch for

No Interaction Found — But Data Suggests Pomegranate and Rifapentine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 4 of them are worth acting on rather than waiting out — marked below.

  • Shortness of breath / A severe allergic reaction / An allergic reaction Worth acting on Additional detail

    Pomegranate

    “Orally, pomegranate fruit or seeds may cause allergic reactions. These allergic reactions occur more commonly in people who are allergic to other plants. In rare cases, pomegranate fruit can cause angioedema. Angioedema seems to occur without warning and in people who have eaten pomegranate for many years. Patients should be told to stop eating pomegranate if swelling of the tongue or face develops.”

How to take them

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

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

See Every Supplement That Interacts With Rifapentine

This page covers Pomegranate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Rifapentine page lists 64 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 1 major · 53 moderate · 10 minor.

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.”

About Pomegranate

What is Pomegranate?

Pomegranate
  • Heart and blood vessel health
  • Antioxidant support
  • High blood pressure
  • Inflammation
  • Digestive upset
  • Skin health

Pomegranate is a nutrient-rich fruit that is high in antioxidants and is widely enjoyed as food and juice. Early research suggests it may support heart health and blood pressure, but the evidence is still limited and not strong enough to call it a proven treatment. As a food it is generally safe, but talk to your pharmacist or doctor before using concentrated extracts, especially if you are pregnant, breastfeeding, or take medications.

Punica granatum · Lythraceae · Fruit, juice, seeds (arils), peel/rind, flower, and leaf · Fresh fruit, juice, extract capsules, powder, tea, and topical products

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

Pomegranate: dosing

There is no single established standard dose for pomegranate. In studies, amounts have varied widely depending on whether the fruit, juice, or extract was used.If you use a pomegranate supplement, follow the directions on the product label and do not exceed the recommended amount.

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.

Taking Pomegranate and Rifapentine Together: Common Questions

Is it safe to take Pomegranate with Rifapentine?
We do not list a known interaction between Pomegranate and Rifapentine. 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.
Do Pomegranate and Rifapentine have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Pomegranate and Rifapentine at the same time of day?
At least one FDA label for a product containing Rifapentine says to take it with food. If you take Pomegranate on an empty stomach out of habit, keep them separate and take Rifapentine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Rifapentine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Pomegranate and Rifapentine combination checked?
Interactions in our licensed database are recorded against drug classes. Rifapentine is filed under 4 classifications, and Pomegranate has documented interactions with 9 drug classes — none of Rifapentine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Pomegranate interact with any other medications?
Yes. Pomegranate has 922 documented drug interactions in our database — Rifapentine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Rifapentine interact with any supplements?
Yes. Rifapentine has documented interactions with 64 supplements in our database — Pomegranate is not one of them. The Rifapentine interaction page linked on this page lists every one, ranked by severity.
