INTRODUCTION

DIXIN PEAD contains Digoxin which belongs to the group of medicine called cardiac glycosides. It is indicated for the treatment of arrhythmias and heart failure. An arrhythmia is a heart rhythm disorder characterized by abnormal generation and conduction of cardiac impulses leading to an irregular heartbeat. As a result, the heart beats at a wrong speed which causes chest pain, fluttering in the heart, fainting or dizziness. Heart failure is a chronic condition in which the heart does not pump adequate amount of blood required for the circulation. Symptoms includes fatigue, difficulty in breathing, shortness of breath, swollen legs and fast heartbeat.

Digoxin works by correcting the abnormal heart rhythm into a normal rhythm. It also improves cardiac contractility and ejection fraction which makes the heart pump more efficiently and increases blood circulation throughout the body. While taking this medicine, your doctor would periodically monitor your kidneys and concentration of digoxin in blood to avoid unwanted side effects. This medicine can be taken with or without meals. However, avoid taking this medicine with foods rich in fibre, as it interferes in the absorption of digoxin.

The most common side effects of taking this medicine are nausea, vomiting, palpitation, dizziness or blurred vision. Contact your doctor if any of the symptoms bothers you. Before taking this medicine, inform your doctor if you have any heart disease apart from arrhythmia and heart failure. This medicine should be taken with caution in patients having lung or kidney disease. If you are pregnant, or think you may be pregnant or breastfeeding, consult your doctor before taking this medicine. Your doctor would select an appropriate dose for you depending upon your condition.

USES OF DIXIN PEAD

• Arrhythmia
• Heart failure

HOW DIXIN PEAD WORKS

Following oral administration, digoxin directly stimulates the parasympathetic nervous system through vagus nerve and slows the electrical conduction in the AV (atrioventricular) node, thus decreasing the heart rate. It also increases cardiac contractility by reversibly inhibiting the activity of an enzyme called Na-K ATPase pump (sodium-pump) which is responsible for controlling the movement of ions into the heart. This increases the influx of sodium and calcium in the myocardial cells, leading to an increase in the force of contraction, thus making the heart pump more efficiently.

DIRECTIONS FOR USE

Take this medicine as directed by your physician. It can be taken with or without meals. Shake well before use. Your doctor will decide the correct dose and duration for you depending upon your age, body weight and health condition. Continue to take this medicine, as long as your doctor tells you to do so, to obtain better results.

FAQs ABOUT DIXIN PEAD

Can DIXIN PEAD and metoprolol be taken together?

No. Avoid concomitant use of this medicine with beta-blocker (e.g. atenolol, metoprolol) because it may increase the risk of irregular heartbeat.

Can you stop taking DIXIN PEAD abruptly?

No. Do not stop taking this medicine abruptly without consulting your doctor, because it may worsen your existing condition.

Can I drink alcohol while taking DIXIN PEAD?

No. Avoid consumption of alcohol while taking this medicine.

Is DIXIN PEAD a steroid?

No. This medicine is not a steroid. It is a cardiac glycoside used to treat arrhythmia (abnormal heartbeat) and heart failure.
