The short answer
Have Asclepias tuberosa checked before taking it with sotalol. The exact interaction is unproven, and root chemistry cannot be assumed to match every aerial-part or commercial preparation.
What this answer covers
Oral sotalol with the exact supplement preparation described below.
- Supplement or preparation
- Asclepias tuberosa
- Medication ingredient
- sotalol
Roots contain compounds that deserve attention
A chemical study identified cardenolide glycosides in Asclepias tuberosa roots. This makes the plant part important, but laboratory isolation does not tell us how much reaches the body from a particular product.
A different plant part means different evidence
A separate study characterized steroidal glycosides from the aerial parts. Those results cannot authenticate a root extract, prove it safe or establish the same exposure as a prescribed cardiac glycoside.
The clinical combination remains uncertain
The reviewed sources did not establish how this exact product changes sotalol absorption or clinical effects. No dose or spacing interval was validated. Product review is more useful than treating a theoretical mechanism as a measured interaction.
Keep the rhythm-treatment plan consistent
Sotalol requires attention to kidney function, heart rhythm and potassium and magnesium levels. Do not stop prescribed replacement minerals or change the medicine on your own. A new supplement should be checked against the actual treatment plan.
Evidence and practical considerations
Side effects & toxicity
Have Asclepias tuberosa checked before taking it with sotalol. The exact interaction is unproven, and root chemistry cannot be assumed to match every aerial-part or commercial preparation.
- Exact scope
- Oral sotalol with the exact supplement preparation described below. with Oral sotalol; intravenous cases are identified as indirect route evidence where discussed.
- Medication form and route
- oral
What remains uncertain
- Exact plant root chemistry is not a clinical beta-blocker interaction. Aerial-part composition differs; no exact efficacy-loss, toxicity rate or protective interval established.
Factors that may matter: Exact ingredient and preparation; Kidney function and clinical indication; Concomitant medicines.

dailymed.nlm.nih.gov · Source check Sep 10, 2026
Population: Patients prescribed oral sotalol.
Oral sotalol exposure is reduced by the studied aluminum oxide/magnesium hydroxide antacid. The label advises a two-hour interval. Low potassium or magnesium increases the risk of dangerous rhythm effects.
How this applies: Exact active-ingredient and oral-route context.
Label omission of an herb does not prove safety. No invented exact supplement interaction rate or universal spacing rule.
Source 2: Original phytochemical study
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: Laboratory chemical analysis of Asclepias tuberosa roots.
Investigators isolated multiple cardenolide glycosides.
How this applies: Root-specific chemistry supports caution about identity without inventing an interaction.
Chemical identification does not establish human toxicity, clinical beta-blocker co-use or a safe amount. Root PDF is image-only; original abstract inspected.
Source 3: Original phytochemical study
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: Laboratory analysis of Asclepias tuberosa aerial parts.
Different steroidal glycosides were characterized; the paper distinguishes the material from traditional root use.
How this applies: Shows why plant part must be specified.
Aerial extracts and roots are not interchangeable. No human medication interaction experiment or negative safety proof.
