Special instructions

Take Digoxin only as directed, and do not stop unless directed to stop by your physician.

While your child is taking Digoxin, the doctor may want you to check the pulse (heart rate) everyday. If it is much slower or more rapid than usual, check with the doctor / nurse. Such changes may mean side effects are starting.

What should I do if my child misses a dose?

If a dose of Digoxin is missed, the child should take it as soon as you remember, unless it is almost time for the next dose. If it is almost time for the next dose, skip the missed dose, and resume the usual dosing schedule. Do not "double-up" to catch up.

Digoxin side effects

Digoxin may cause loss of appetite, nausea, vomiting, lower stomach pain, diarrhea, unusual tiredness or weakness. Also slow, uneven or fast heartbeat, blurred vision (yellow, green or white circles around things), drowsiness, confusion or mental depression, headache or fainting.

Warning signs

Call your doctor / clinic immediately if your child has trouble breathing, or swelling in the lower legs or ankles. These may be signs that the dose needs to be changed. Do not change the dose without checking with the doctor.
