What is digoxin toxicity?
A person with digoxin toxicity has poor heart function, due to too much digoxin in the bloodstream.

This may occur if the digoxin dose is too high, the body suddenly becomes more sensitive to digoxin, or the body is unable to remove digoxin from the bloodstream. Digoxin is used to treat heart failure. About 1 out of every 100 people taking digoxin develops digoxin toxicity.
