How does digoxin work?
Digoxin slows down and strengthens the heartbeat, helping the heart pump blood more effectively and reducing symptoms of heart failure and irregular heart rhythms.
What is digoxin used to treat?
Digoxin is commonly prescribed for:
- Heart failure (to improve heart function and reduce symptoms like breathlessness and swelling)
- Atrial fibrillation (AF) (to help control heart rate in people with irregular heartbeats)
Who can take digoxin?
Digoxin is suitable for most adults with heart failure or atrial fibrillation, as prescribed by a doctor.
Who might not be able to take digoxin?
Digoxin may not be suitable if you:
- Have low potassium or magnesium levels
- Have kidney disease (as digoxin is removed by the kidneys)
- Have certain heart conditions (such as heart block or recent heart attacks)
- Are taking other medications that affect heart rhythm
Can I take digoxin if I’m pregnant or breastfeeding?
Digoxin may be used during pregnancy or breastfeeding, but only under medical supervision.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is digoxin?
Digoxin is highly effective at improving heart function and regulating heart rate when taken correctly.
What should I do if I take too much?
Taking too much digoxin can cause toxicity, leading to nausea, dizziness, vision changes, or irregular heartbeats. If you think you’ve taken too much, seek emergency medical help immediately.

- For heart failure: 125mcg to 250mcg once daily
- For atrial fibrillation: 62.5mcg to 250mcg once daily
