Digoxin Tablets are a cardiac glycoside indicated for: Treatment of mild to moderate heart failure in adults. ( 1.1 ) Increasing myocardial contractility in pediatric patients with heart failure. ( 1.2 ) Control of resting ventricular rate in patients with chronic atrial fibrillation in adults. ( 1.3 ) 1.1 Heart Failure in Adults Digoxin Tablets are indicated for the treatment of mild to moderate heart failure in adults. Digoxin Tablets increase left ventricular ejection fraction and improve heart failure symptoms as evidenced by improved exercise capacity and decreased heart failure-related hospitalizations and emergency care, while having no effect on mortality. Where possible, Digoxin Tablets should be used in combination with a diuretic and an angiotensin-converting enzyme (ACE) inhibitor. 1.2 Heart Failure in Pediatric Patients Digoxin Tablets increase myocardial contractility in pediatric patients with heart failure. 1.3 Atrial Fibrillation in Adults Digoxin Tablets are indicated for the control of ventricular response rate in adult patients with chronic atrial fibrillation.

Digoxin Tablets are contraindicated in patients with: Ventricular fibrillation [see Warnings and Precautions (5.1)] Known hypersensitivity to digoxin (reactions seen include unexplained rash, swelling of the mouth, lips or throat or a difficulty in breathing). A hypersensitivity reaction to other digitalis preparations usually constitutes a contraindication to digoxin. Ventricular fibrillation. ( 4 ) Known hypersensitivity to digoxin or other forms of digitalis. ( 4 )

Risk of rapid ventricular response leading to ventricular fibrillation in patients with AV accessory pathway. ( 5.1 ) Risk of advanced or complete heart block in patients with sinus node disease and AV block. ( 5.2 ) Digoxin toxicity: Indicated by nausea, vomiting, visual disturbances, and cardiac arrhythmias. Advanced age, low body weight, impaired renal function and electrolyte abnormalities predispose to toxicity. ( 5.3 ) Risk of ventricular arrhythmias during electrical cardioversion. ( 5.4 ) Not recommended in patients with acute myocardial infarction. ( 5.5 ) Avoid Digoxin Tablets in patients with myocarditis. ( 5.6 ) 5.1 Ventricular Fibrillation in Patients With Accessory AV Pathway (Wolff-Parkinson-White Syndrome) Patients with Wolff-Parkinson-White syndrome who develop atrial fibrillation are at high risk of ventricular fibrillation. Treatment of these patients with digoxin leads to greater slowing of conduction in the atrioventricular node than in accessory pathways, and the risks of rapid ventricular response leading to ventricular fibrillation are thereby increased. 5.2 Sinus Bradycardia and Sino-atrial Block Digoxin Tablets may cause severe sinus bradycardia or sinoatrial block particularly in patients with pre-existing sinus node disease and may cause advanced or complete heart block in patients with pre-existing incomplete AV block. Consider insertion of a pacemaker before treatment with digoxin. 5.3 Digoxin Toxicity Signs and symptoms of digoxin toxicity …

8.1 Pregnancy Risk Summary Experience with digoxin in pregnant women over several decades, based on published retrospective clinical studies and case reports, has not led to the identification of a drug associated risk of major birth defects, miscarriage or adverse maternal and fetal outcomes. Untreated underlying maternal conditions, such as heart failure and atrial fibrillation, during pregnancy pose a risk to the mother and fetus (see Clinical Considerations) . Animal reproduction studies have not been conducted with digoxin. The estimated background risk of major birth defects and miscarriage for the indicated population(s) are unknown. All pregnancies have a background risk of birth …
