Pindolol

Interaction

Pindolol

This drug is from the beta-adrenergic blockers or “beta blockers” family of drugs, which are used to treat high blood pressure, angina, heart arrhythmia, tremors, alcohol withdrawal, glaucoma, and other conditions. They are also used to prevent migraine headaches, stage fright, and second heart attacks.

Interactions Details

Interactions with Vitamins

Potassium

Some beta-adrenergic blockers (called “nonselective” beta blockers) decrease the uptake of potassium from the blood into the cells,1 leading to excess potassium in the blood, a potentially dangerous condition known as hyperkalemia.2 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.

Interactions with Herbs

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.3
