Pomegranate and Captopril

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Pomegranate interacts with whole categories of medication. Captopril falls into 2 of those categories, so it can interact with Pomegranate in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Captopril

Captopril falls under ANTIHYPERTENSIVE DRUGS — the group Pomegranate interacts with.

Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.
Severity Moderate Likelihood Possible Evidence B

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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: pomegranate, especially as juice, can nudge your blood pressure down a little on its own. Captopril already lowers blood pressure by relaxing your blood vessels, so adding pomegranate may stack on top of that effect. The result could be blood pressure that drops a bit more than expected.

If that happens, you might feel dizzy or lightheaded, especially when standing up quickly, or notice tiredness. The good news is this is considered a modest effect, and enjoying pomegranate as a normal food is unlikely to cause trouble for most people. Regular or concentrated juice is where it's more worth watching. If you notice symptoms or want to add a daily pomegranate habit, just check in with your pharmacist or doctor first.

ACE INHIBITORS (ACEIs)

2 of 2

Captopril also falls under 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.
Severity Moderate Likelihood Possible Evidence B

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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: pomegranate seems to have a mild blood-pressure-lowering action of its own, a little like what captopril does. So when you pair the two, the effects can stack up. In real life that might show up as feeling lightheaded, dizzy when you stand, more tired than usual, or having a blood pressure reading that dips lower than expected.

I want to be honest about the evidence though. This is mostly theoretical, based on the idea that pomegranate acts a bit like an ACE inhibitor, not on strong human studies. Enjoying pomegranate as an occasional fruit or glass of juice is unlikely to cause trouble for most folks. Daily juice or concentrated extracts are where I'd be more cautious. If you notice dizziness or want to add pomegranate regularly, just check with your pharmacist or doctor first.

From our pharmacist’s overview on the Captopril page

“Anyone taking captopril (Capoten), an ACE inhibitor for high blood pressure and heart failure, should treat this list with genuine care rather than a quick skim. Most of the ingredients here act on blood pressure itself, some dropping it lower than intended and others, tyramine among them, pushing it back up and working against the med…”

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.

About Captopril

What Is Captopril Used For?

Brand names: Capoten, Acepril

Captopril tablets are used to treat high blood pressure (hypertension), heart failure, and left ventricular dysfunction (weakened pumping function of the heart) in stable patients after a heart attack. For the heart attack indication, it helps improve survival and reduces the chance of developing full heart failure.

Captopril tablets are also used to slow the progression of diabetic nephropathy (kidney damage caused by diabetes) in people with type 1 (insulin-dependent) diabetes who have retinopathy and significant protein in their urine. It reduces the risk of the kidneys failing to the point of needing dialysis or a transplant.
