Pomegranate and Clonidine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Clonidine

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

Here's the simple version: clonidine already lowers your blood pressure by calming the signals that tighten your blood vessels and speed up your heart. Pomegranate, especially as juice, can nudge your blood pressure down a little on its own. Put the two together and those small drops can add up, so your pressure may dip a bit lower than expected.

What that can feel like is dizziness, lightheadedness when you stand up, tiredness, or feeling a little foggy. The good news is this effect is mild and based on modest research, and an occasional glass of juice or some of the fruit usually isn't a big deal. If you drink it daily or use concentrated extracts, mention it to your pharmacist or doctor so they can keep an eye on your numbers.

See Every Supplement That Interacts With Clonidine

This page covers Pomegranate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Clonidine page lists 138 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Tyramine (major) and Adrafinil (moderate).

By severity: 4 major · 113 moderate · 21 minor.

From our pharmacist’s overview on the Clonidine page

“American hellebore is the ingredient I would want a clonidine (Catapres) patient to know about first. Its alkaloids lower blood pressure even in small doses and slow the heart, both things clonidine already does, so the combination can drop someone dangerously low.”

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 Clonidine

What Is Clonidine Used For?

Brand name: Catapres

Clonidine is used to treat high blood pressure (hypertension). Several products — including Clonidine Hydrochloride tablets, Javadin oral solution, Nexiclon XR extended-release tablets, and Catapres-TTS skin patches — are approved for this use, either alone or combined with other blood pressure medicines.

Extended-release formulations — including Onyda XR oral suspension and clonidine hydrochloride extended-release tablets (such as Kapvay) — are approved to treat ADHD in children and teenagers ages 6 to 17, either on their own or alongside stimulant medications. Separately, clonidine injection products (Duraclon and others) are used alongside opioid pain medicines to treat severe cancer pain that opioids alone cannot control adequately.
