Summary
Digoxin is used to treat heart failure, which is when the heart can't pump blood effectively, and certain irregular heartbeats like atrial fibrillation, which is an irregular and often rapid heart rate. It helps improve heart function and manage symptoms like shortness of breath and fatigue.
Digoxin strengthens the heart muscle and improves its efficiency, which helps the heart pump more effectively and maintain a regular rhythm. It increases the force of heart contractions and slows down the heart rate, which can help control irregular heartbeats.
The usual starting dose for adults is 0.125 mg to 0.25 mg once daily. The dose may be adjusted based on individual response and health needs. It's taken orally, either in the morning or evening, with or without food. Always follow your doctor's specific dosing instructions.
Common side effects of Digoxin include nausea, vomiting, and dizziness. These occur in a small percentage of users. Serious side effects like vision changes, confusion, and irregular heartbeats require immediate medical attention. Always report any new or worsening symptoms to your doctor.
Digoxin can cause toxicity, which is when the drug builds up to harmful levels, leading to symptoms like nausea and dizziness. It's crucial to take the exact dose prescribed and have regular blood tests. Avoid if allergic or with certain heart conditions like ventricular fibrillation, which is a life-threatening heart rhythm problem.

Can I take Digoxin with other prescription drugs?
Digoxin has several important drug interactions. Medications like amiodarone, which is used to treat irregular heartbeats, and verapamil, which is used for high blood pressure, can increase Digoxin levels and risk of toxicity. Diuretics, which are water pills, can also affect Digoxin levels by altering potassium levels in your body. Always inform your doctor about all medications you take to manage these interactions safely. Regular monitoring of Digoxin levels can help prevent adverse effects.

Always follow your doctor's instructions and report any unusual symptoms immediately.
Is Digoxin addictive?
