Digoxin is a medication that is commonly used to treat heart failure and arrhythmias, such as atrial fibrillation.

Digoxin toxicity can occur due to various factors, including:
Treatment for digoxin toxicity depends on the severity of the symptoms. Mild cases may not require any treatment other than monitoring of symptoms and reducing the dose of digoxin. More severe cases may require hospitalization and treatment with medications to control the heart rate and rhythm, such as beta blockers or calcium channel blockers. In cases of life-threatening toxicity, treatments such as digoxin immune fab (also known as digoxin-specific antibody fragments) or cardiac pacing may be necessary.
It is important to monitor digoxin levels regularly in patients taking the medication, and to be aware of the risk factors for toxicity. Patients should also be educated on the symptoms of digoxin toxicity and advised to seek medical attention if they experience any of these symptoms.
