What is the most important information I should know about digoxin?
You should not use this medication if you are allergic to digoxin, or if you have
ventricular fibrillation (a heart rhythm disorder of the ventricles, or lower chambers of the heart
that allow blood to flow out of the heart).
Before using digoxin, tell your doctor if you have certain heart conditions, especially "AV
block" (unless you have a pacemaker), or a recent history of heart attack. Also tell your doctor if
you have kidney disease, a thyroid disorder, an electrolyte imbalance (such as low levels of
calcium, potassium, or magnesium in your blood), or if you are malnourished or have recently
been sick with vomiting or diarrhea.
Keep taking digoxin as directed, even if you feel well. Get your prescription refilled
before you run out of medicine completely.
Do not stop taking digoxin without first talking to your doctor. Stopping suddenly
may make your condition worse.
Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not
drinking enough fluids. Digoxin overdose can occur more easily if you are dehydrated.
There are many other medicines that can interact with digoxin. Tell
your doctor about all the prescription and over-the-counter medications you use. This includes
vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a
new medication without telling your doctor. Keep a list with you of all the medicines you use
and show this list to any doctor or other healthcare provider who treats you.
