What is this medication?

DIGOXIN (di JOX in) treats heart failure. It may also be used to treat a type of arrhythmia known as AFib (atrial fibrillation). It works by helping your heart beat stronger, making it easier for your heart to pump blood to the rest of the body. It also slows down overactive electric signals in the heart, which stabilizes your heart rhythm.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
