A healthcare provider may prescribe digoxin (Lanoxin®) to treat congestive heart failure or a type of irregular heart rhythm called atrial fibrillation. This medication is available as a tablet, an injection, and an elixir (a liquid form taken by mouth). The tablets and elixir are usually taken by mouth once a day. Children may need to take digoxin more often than once a day.
For this medication to work properly, it must be taken as prescribed. If you forget to take your digoxin dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the one you missed and continue with your regular schedule. Do not take a double dose. If you take too much digoxin, it may cause a potentially dangerous condition called digoxin toxicity.
