Digoxin is a drug used to treat some heart problems.
One of these problems, heart failure, results when the heart can't pump blood well enough to supply the body's needs. If you have heart failure, digoxin can improve your heart's ability to pump blood. Better pumping of the heart will often improve symptoms such as shortness of breath. Digoxin helps by slowing down and controlling the heart rate. It may take several weeks to several months for digoxin to start working.
