Indian Snakeroot and Sotalol

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

Major

BETA-BLOCKERS

Why this applies to Sotalol

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

Theoretically, taking Indian snakeroot with beta-blockers might increase the risk of bradycardia and/or hypotension.
Indian snakeroot contains small amounts of reserpine. Reserpine causes catecholamine-depletion. Concomitant use of Indian snakeroot and beta-blockers might increase the risk or bradycardia and/or hypotension.
Severity Major Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the gist for Sotalol: this medicine already slows your heart rate and steadies your rhythm, partly by blocking adrenaline-type signals. Indian snakeroot contains reserpine, which works in a different but overlapping way, by draining the body's stores of those same adrenaline-like chemicals. Stack the two and their effects can pile on top of each other.

In plain terms, combining them could push your heart rate too low (bradycardia) or drop your blood pressure too far, leaving you dizzy, lightheaded, very tired, or faint. This concern is based on how these substances work rather than hard human studies, so it's theoretical, but Sotalol is a drug where small heart changes matter. Please don't start or stop anything on your own. Check with your pharmacist or doctor first.

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 Indian Snakeroot

What is Indian Snakeroot?

Indian Snakeroot
  • High blood pressure
  • Anxiety and stress
  • Insomnia
  • Agitation
  • Fever (traditional use)

Indian snakeroot is a traditional Ayurvedic plant that contains reserpine, a compound with real blood-pressure-lowering and sedative effects. Because its potent alkaloids can cause serious side effects like depression and very low blood pressure, it should never be used without medical supervision. It is not a safe or simple home remedy, and many countries restrict its use.

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.
