Hoodia and Sotalol

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

Moderate

BETA-BLOCKERS

Why this applies to Sotalol

Sotalol falls under BETA-BLOCKERS — the group Hoodia interacts with.

Evidence from in vitro research shows that hoodia may stimulate beta-adrenergic receptors. Also, clinical research shows that hoodia can increase blood pressure and heart rate. Theoretically, using hoodia with beta-blockers might decrease the effects of these medications. Some beta-blocker drugs include atenolol (Tenormin), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), and propranolol (Inderal).
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 thing to understand about sotalol: it's a beta-blocker, so it works by quieting down certain signals on your heart to steady your rhythm and keep your heart rate in check. Hoodia, on the other hand, may do the opposite in the body. Lab research and some human studies suggest it can nudge those same beta receptors in the stimulating direction, which can bump up heart rate and blood pressure. So in theory, taking hoodia could push back against what your sotalol is trying to do.

For a heart rhythm drug like sotalol, even small swings matter, so I'd rather you not gamble on it. That said, this concern is theoretical and based mostly on how things work on paper, not strong human proof. Please run it by your pharmacist or doctor before trying hoodia.

From our pharmacist’s overview on the Sotalol page

“Sotalol controls heart rhythm by lengthening the heart's electrical reset time, the QT interval, which is why this list of 43 interacting supplements deserves a careful read, not a skim. Eight are rated major, and most of the serious entries stack further QT prolongation on top of what sotalol already causes, raising the risk of a dang…”

About Hoodia

What is Hoodia?

Hoodia
  • Appetite suppression
  • Weight loss
  • Reducing food cravings
  • Traditional use for hunger and thirst on long journeys

Hoodia is a succulent plant from southern Africa that is marketed as an appetite suppressant for weight loss, but solid human evidence that it actually works is lacking. The few quality studies done have not shown meaningful weight loss, and some products on the market may not even contain real hoodia. Talk with your pharmacist or doctor before trying it, and avoid it if you are pregnant or breastfeeding.

About Sotalol

What Is Sotalol Used For?

Brand names: Betapace AF, Betapace, Sotacor, Sorine

Sotalol is used to treat documented, life-threatening ventricular arrhythmias (dangerous irregular heart rhythms originating in the lower chambers of the heart), such as sustained ventricular tachycardia (a rapid, sustained abnormal heartbeat). Because it carries real risks of its own, it is generally reserved for arrhythmias serious enough to be life-threatening — not for mild or symptom-only rhythm problems.

It is not recommended for people with less severe arrhythmias, even if those arrhythmias cause symptoms, and it should be avoided in people with asymptomatic (no-symptom) extra heartbeats called ventricular premature contractions.
