Our bottom line

Digoxin is a good backup for treating heart failure symptoms, but it doesn't, by itself, lower your risk of death.


  • Used for some abnormal heart rhythms, and for heart failure that can't be controlled by other medications.
  • Relieves shortness of breath, and makes it easier to be active without having symptoms.
  • In studies, Digoxin lowered the risk of having to be admitted to the hospital for worsening heart failure.
What do people say?

  • For heart failure, relieves symptoms, but does not lower the risk of death. That's why it's usually used together with other heart failure medicines that do lower the risk of death.
  • Requires blood tests, especially during the first few weeks of treatment.
