Artichoke 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 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, 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. Artichoke leaf extract may nudge blood pressure down a little on its own. In studies, that effect was small (roughly 3 points on the top number and 2 on the bottom), and this concern is mostly theoretical, based on how the two work rather than reports of real problems.

Still, when you stack two things that lower pressure, the totals can add up. If your pressure dips too low, you might feel dizzy, lightheaded, tired, or faint when standing up. If you'd like to try artichoke, check with your pharmacist or doctor first and keep an eye on your blood pressure.

See Every Supplement That Interacts With Clonidine

This page covers Artichoke 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 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.
