Digoxin is used to treat heart failure, usually with other medications. It is also used to treat some types of irregular heartbeat (such as chronic atrial fibrillation). Treatment of heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treatment of irregular heartbeat can also improve your ability to exercise. Digoxin belongs to a class of medications that is called cardiac glycosides. It works by affecting certain minerals (sodium and potassium) in the heart cells. This reduces the strain on the heart and helps to maintain a normal, steady, and strong heartbeat.
Take this medicine orally with or without food, usually once a day or as directed by your doctor. If you are using the liquid form of this medicine, carefully measure the dose using the dropper provided by the manufacturer. Never use a household spoon because you may not get the correct dosage.

If you are also taking cholestyramine, colestipol, or psyllium, wait at least 2 hours after taking your digoxin dose before taking any of these products.
If you are taking antacids, kaolin-pectin, magnesia milk, metoclopramide, sulfasalazine, or aminosalicylic acid, take them as far away as possible from your digoxin dose. Ask your pharmacist if you're not sure when to take any of your medications.
The dosage of this medicine is based on your medical condition, age, body weight, laboratory tests, and response to treatment.

Note
Do not share this medicine with others. Laboratory and medical tests (such as digoxin levels, blood mineral levels, kidney function tests, electrocardiograms) should be performed while you are taking this medicine. Keep all medical and laboratory appointments in place. For more details, consult your doctor. Check your blood pressure and pulse (heart rate) regularly while taking this medicine. Learn how to check your blood pressure and pulse at home and share the results with your doctor.
If you forget a dose, take it as soon as it is possible if it is within 12 hours of the scheduled dose. If it is more than 12 hours after the scheduled dose, skip the missed dose. Take your next dose on a regular basis. Don't double your dose to catch up. If you miss more than 2 doses in a row, ask your doctor or pharmacist for a new dosing schedule immediately.

Digoxin is a type of medicine called cardiac glycosides. It is used to control some heart problems, such as irregular heartbeat (arrhythmias) including atrial fibrillation. It can also help manage symptoms of heart failure, usually with other medicines. Digoxin is available on prescription only.
Digoxin belongs to a class of drugs called digitalis glycosides. It is used to improve the strength and efficacy of the heart or to control the rate and rhythm of the heartbeat.
Digoxin increases the strength of the heart muscle contraction by inhibiting the activity of the enzyme (ATPase) which controls the movement of calcium, sodium, and potassium into the heart muscle. Calcium controls the contraction force.
Following are the most common first sign of digoxin toxicity:
For people with ventricular fibrillation: Digoxin cannot be used if you have ventricular fibrillation. It might make your ventricular fibrillation worse. In people with Wolff-Parkinson-White Syndrome: If you have Wolff-Parkinson-White Syndrome, you are at higher risk of abnormal heart rhythm.
Elderly people are at an increased risk of digoxin toxicity. Low doses of digoxin appear to be effective in treating heart failure due to systolic dysfunction and may reduce the incidence of digital toxicity in these patients.
Because digoxin does not affect blood pressure, it is sometimes used on its own in a person with atrial fibrillation who has naturally low blood pressure. Sometimes there is no other effective rate-control treatment that does not lower blood pressure as well.
Digoxin Lanoxin, Digoxin is usually taken in the morning. Your doctor will sometimes ask you to take some blood tests. If you start to get sick (vomiting), develop diarrhea, blurred/yellow vision, or become dizzy, you should contact your doctor immediately for advice.
Toxic effects of digoxin include life-threatening cardiac arrhythmias, particularly ventricular tachycardia and ventricular fibrillation, severe bradycardia (low heart rate), heart block, loss of appetite, nausea or vomiting, and neurological problems, including confusion and visual disturbances.
In this subset of the DIG trial, digoxin was associated with a long-term improvement in renal function and a reduction in death or hospitalization in patients showing this favorable renal response. Additional research is needed to confirm this finding-generating hypothesis.
