Digoxin (digoxin) — Uses, Dosage, Side Effects & Safety

Drug class: Cardiac glycoside

Overview

Digoxin is a medication used to treat certain heart conditions, including heart failure and some types of irregular heartbeat (such as atrial fibrillation). It helps the heart work more efficiently and controls the heart rate, especially when the heart is not pumping as strongly as it should. Digoxin works by increasing the force of heart muscle contractions and slowing down the electrical signals in the heart, which helps restore a normal, steady rhythm. This can improve symptoms like shortness of breath, fatigue, and swelling in people with heart failure. Patients should know that digoxin requires regular monitoring, as the difference between a helpful dose and a harmful dose is small. Always take digoxin exactly as prescribed and report any unusual symptoms to your healthcare provider.
