Digoxin

Common use

Digoxin is a cardiac glycoside used to treat heart failure and certain types of irregular heartbeats, such as atrial fibrillation. It helps the heart work more efficiently by increasing the force of myocardial contractions and regulating heart rhythm. The medication improves symptoms like shortness of breath and fatigue. It is commonly used in long-term management of chronic heart conditions.

Dosage and direction

Digoxin is typically taken once daily by mouth, with or without food. Dosage is carefully calculated based on age, weight, kidney function, and medical condition. Blood tests are often required to monitor drug levels and prevent toxicity. Always follow your doctor's instructions precisely and do not adjust your dose without consultation.

Drug interaction

Digoxin interacts with many medications, including diuretics, beta-blockers, calcium channel blockers, and certain antibiotics.
