    Drug Information

    Sotalol is used to treat certain types of heart arrhythmia , and is in a family of drugs known as beta-adrenergic blockers.

    Common brand names:

    Betapace, Betapace AF

    Summary of Interactions with Vitamins, Herbs, & Foods

    Types of interactions: Beneficial Adverse Check

    Replenish Depleted Nutrients

    • none

    Reduce Side Effects

    • none

    Support Medicine

    • none

    Reduces Effectiveness

    • Calcium

      One controlled study showed that taking sotalol with a calcium gluconate solution dramatically reduces the absorption of the drug. Consequently, people who take a calcium supplement should take sotalol an hour before or two hours after the calcium.

    Potential Negative Interaction

    • Pleurisy Root

      As pleurisy root and other plants in the Aesclepius genus contain cardiac glycosides, it is best to avoid use of pleurisy root with heart medications such as beta-blockers.

      The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

    Explanation Required 

    • Potassium

      People with prolonged diarrhea and vomiting, as well as those taking potassium-depleting diuretics, might develop low blood potassium levels. Individuals with low blood potassium levels who take sotalol have an increased risk of developing a serious heart arrhythmia and fainting. Therefore, people taking sotalol should have their blood potassium levels checked regularly and may need to supplement with potassium, especially when taking potassium-depleting diuretics.

      Some beta-adrenergic blockers (called "nonselective" beta blockers) decrease the uptake of potassium from the blood into the cells, leading to excess potassium in the blood, a potentially dangerous condition known as hyperkalemia. People taking beta-blockers should therefore avoid taking potassium supplements, or eating large quantities of fruit (e.g., bananas), unless directed to do so by their doctor.

    The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers' package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
