What is this page for?

First and foremost: how Pomegranate interacts with medications. The heart of this page is the interaction list — every drug Pomegranate is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Pomegranate is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist.

Pomegranate Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Pomegranate drug interaction appears low for most people. None of the listed interactions are rated major, most are minor, and even the moderate ones rest on theoretical or limited evidence rather than well-controlled human studies.

Interactions deserving the most attention

The interactions worth the most awareness involve closely monitored medicines. Pomegranate juice can modestly lower blood pressure, so it could add to the effect of blood pressure medications, including ACE inhibitors. Single case reports link pomegranate juice to changes in bleeding measures with warfarin and to muscle breakdown in one person taking rosuvastatin, though neither is proven. Because these drugs have narrow safety margins, any shift in their effect matters more than it would for other medicines.

What the rest of the list means

The long list of interacting medications mostly reflects theory, not documented harm. Pomegranate may affect enzymes the body uses to clear certain drugs, so hundreds of medications get flagged automatically. In human studies, several of these predicted effects either did not appear or were too small to matter clinically.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

The kinds of drugs Pomegranate affects

Every type of medication (drug category) Pomegranate is known to interact with. Open any category for the detail — or search your exact drug in the checker above.

All 9 drug categories Pomegranate interacts with

Ace Inhibitors (aceis)Antihypertensive DrugsCytochrome P450 2d6 (cyp2d6) SubstratesRosuvastatin (crestor)Warfarin (coumadin)Carbamazepine (tegretol)Cytochrome P450 2c9 (cyp2c9) SubstratesCytochrome P450 3a4 (cyp3a4) SubstratesTolbutamide (orinase)

Ace Inhibitors (Aceis)

Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.
Pomegranate juice is thought to have ACE inhibitor-like effects.

Likelihood Possible Evidence B

Antihypertensive Drugs

Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.

Likelihood Possible Evidence B

Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.
In vitro, pomegranate juice inhibits CYP2D6. However, the clinical significance of this potential interaction in humans is not known.

Likelihood Possible Evidence D

Rosuvastatin (Crestor)

Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.
In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis.

Likelihood Possible Evidence D

Warfarin (Coumadin)

Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.
In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase. In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption. The mechanism of this potential interaction is unclear.

Likelihood Possible Evidence D

Carbamazepine (Tegretol)

Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4. However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans.

Likelihood Unlikely Evidence D

Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.

Likelihood Unlikely Evidence B

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.
Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice. In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times; however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration. Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans.

Likelihood Unlikely Evidence B

Tolbutamide (Orinase)

Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9. Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans. This interaction does not appear to be clinically significant in humans.

Overview

Pomegranate (Punica granatum) is a fruit-bearing shrub or small tree that is native to the Middle East and South Asia and is now grown in warm regions around the world. It is best known for its bright red, juicy seeds (called arils), which have a tart, slightly sweet flavor.

People eat the fresh fruit, drink the juice, and use various parts of the plant — including the peel, flowers, and leaves — in traditional medicine. Today pomegranate is also sold as juice concentrates, dried powders, and extract capsules that are often standardized for antioxidant compounds.

It is popular partly because it is a rich source of antioxidants, vitamins, and minerals. In traditional systems of medicine, it has long been used for digestive complaints and for its supposed anti-inflammatory effects.

How it works

Pomegranate contains a range of plant compounds, including polyphenols such as punicalagins and ellagic acid, along with anthocyanins (the pigments that give the fruit its red color) and tannins. These are thought to act as antioxidants, helping to neutralize unstable molecules called free radicals.

Researchers believe these compounds may also help relax blood vessels, support healthy blood flow, and reduce inflammation. The seed oil contains unique fatty acids, and the peel is especially rich in tannins.

It is important to note that much of this information comes from laboratory and animal studies. How well these effects occur in the human body, and at what doses, is still not fully understood.
