Digoxin (Lanoxin®) is a medicine used for various heart conditions including arrhythmias and congestive heart failure. It is used to improve the strength and efficiency of the heart, or to control the rate and rhythm of the heartbeat. This leads to better circulation (blood flow) and less swelling of hands and ankles.
Digoxin is available in a tablet, liquid and in intravenous (IV) form. This medicine is also called digitalis.
