How does this medication work? What will it do for me?
Digoxin is used to treat congestive heart failure and to treat certain types of abnormal heart rhythms. It helps to reduce the symptoms of congestive heart failure (e.g., swelling in the ankles, feet, and hands; shortness of breath; frequent fatigue) by helping to increase the strength of the heart so that it pumps more efficiently. Digoxin also helps to maintain a normal heart rhythm in patients with atrial fibrillation.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Kidney disease: People with kidney disease may need a lower dose of digoxin.
Magnesium levels: Low blood levels of magnesium increase the risk of side effects with digoxin. It is important that magnesium levels be checked periodically when taking digoxin.

Pregnancy: Digoxin should be taken by pregnant women only if clearly needed, as the effects of this medication during pregnancy are currently unknown.
