Artichoke and Hydrochlorothiazide, Propranolol

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

Why Are There 2 Interactions?

Artichoke interacts with whole categories of medication. Hydrochlorothiazide, Propranolol falls into 2 of those categories, so it can interact with Artichoke 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 Hydrochlorothiazide, Propranolol

Hydrochlorothiazide, Propranolol falls under ANTIHYPERTENSIVE DRUGS — the group Artichoke interacts with.

Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo.
Severity Moderate Likelihood Possible Evidence D

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

Your Inderide combines two blood pressure medicines: hydrochlorothiazide (a water pill) and propranolol (a beta blocker). Both work to bring your blood pressure down. Artichoke leaf extract appears to nudge blood pressure down a little too, by maybe 2 to 3 points in studies. So the concern here is simply additive: the supplement could add to what your medication is already doing.

This is a theoretical, mild concern based on how things work, not a strong warning. The blood pressure drop from artichoke is small. Still, if you notice dizziness, lightheadedness when standing, fatigue, or a slow heartbeat, those could mean your pressure is running low. Don't stop or change anything on your own. Just give your pharmacist or doctor a quick heads-up before adding artichoke.

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

2 of 2

Hydrochlorothiazide, Propranolol also falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES.

Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2C19.
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity. However, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

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 for this combo pill (Inderide), which pairs propranolol with hydrochlorothiazide. The concern on file is that artichoke leaf might block a liver enzyme called CYP2C19. In a test tube, artichoke slowed that enzyme down, which in theory could let certain drugs build up a little more than usual. Neither of these is a prodrug, so if levels did rise, you'd expect a stronger effect, not a weaker one.

For propranolol, that could mean more pronounced effects like a slower heart rate, lower blood pressure, tiredness, or lightheadedness. But honestly, this is theoretical and has never been reported in real people. Culinary artichoke is no worry. If you're using concentrated extract, just give your pharmacist a heads-up.

From our pharmacist’s overview on the Hydrochlorothiazide, Propranolol page

“Inderide combines hydrochlorothiazide, a water pill, with propranolol, a beta blocker, so a supplement that also lowers blood pressure or pulls potassium out of the body hits the drug on its own turf. That describes most of this list, and I'd approach it with genuine care.”
