In each of these trials, randomization to digoxin was associated with better preservation of exercise capacity and with reduced need of failure-related hospitalization, emergency care, and concomitant heart-failure therapy.

Digoxin is contraindicated in patients with a known hypersensitivity to digoxin or other forms of digitalis.
Do not measure from the narrow tip.
Conversion was equally likely, and equally rapid, in the digoxin and placebo groups. As in the smaller trials described above, patients who had been receiving open-label digoxin were withdrawn from this treatment before randomization.
As digoxin levels increase, more and more calcium builds up in the cell. Randomization to digoxin was again associated with a significant reduction in the incidence of hospitalization, whether scored as number of hospitalizations for heart failure (relative risk 75%), risk of having at least one such hospitalization during the trial (RR 72%), or number of hospitalizations for any cause (RR 94%). Prophylactic use of a cardiac pacemaker may be considered if the risk of heart block is considered unacceptable.In pediatric patients, the use of digoxin may produce arrhythmias.
The pharmacokinetics of digoxin are complex and dose determination should take into account patient-specific factors (age, lean body weight, renal function, etc.). massive doses of digoxin should receive All of digoxin's actions are mediated through its effects

Serum potassium levels should be carefully monitored when digoxin is given to patients at high risk of hypokalemia (Because digoxin’s therapeutic and toxic effects are all largely mediated by intracellular calcium distribution, they are affected by abnormalities in serum calcium levels. Despite its limitations, however, digoxin has a place in therapy.
