How should this medicine be used?
Digoxin comes as a tablet, capsule, or pediatric elixir (liquid) to take by mouth. Digoxin is usually taken once a day. The pediatric elixir comes with a specially marked dropper for measuring the dose. If you have difficulty, ask your pharmacist to show you how to use it. It is important that you always take the same brand of digoxin. Different brands of digoxin have different amounts of active drug and your dose would need to be changed.
Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take digoxin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Digoxin helps control your condition but will not cure it. Continue to take digoxin even if you feel well. Do not stop taking digoxin without talking to your doctor.
