Overview
Introduction
Calnif Retard 20mg Tablet is a medicine used to treat high blood pressure (hypertension) and to prevent angina (heart-related chest pain). It is known as a calcium channel blocker and helps to lower blood pressure and reduce the workload of the heart. This helps prevent heart attacks and strokes.
Calnif Retard 20mg Tablet may be prescribed alone or along with other medicines. The dose and how often you need it will be decided by your doctor so that you get the right amount to treat your condition. Your doctor may adjust the dose depending on how you respond to this medicine and your blood pressure levels. You can take it at any time of the day, with or without food, but it is best to take it at the same time each day. Take this medicine as soon as you have taken it out of the packet. It is sensitive to light and may not work properly if it is left out of the pack for too long.
Keep taking it for as long as advised by your doctor. Even if you feel well, do not stop this medicine on your own because high blood pressure often has no symptoms. If you stop taking it, your condition may get worse.
Keeping active with regular exercise, reducing your weight and eating a healthy diet will also help control your blood pressure. Follow your doctor’s advice while taking this medicine.
The most common side effects include fatigue, swelling in the feet or ankles, dizziness, unusual heartbeat (palpitations), flushing, constipation, and headache. Consult your doctor if any of these bother you, or do not go away.

You also need to tell your doctor what other medicines you are taking, especially those used to treat high blood pressure or heart conditions. Avoid excessive alcohol intake while taking this medicine as it can lead to an excessive fall in your blood pressure and make you feel dizzy or light-headed. You should have your blood pressure checked regularly to make sure that this medicine is working properly.

How Calnif Tablet works
Calnif Retard 20mg Tablet is a calcium channel blocker. In high blood pressure, it normalizes the blood pressure by relaxing the blood vessels to reduce the pressure on them, thereby improving the blood flow in the body. In heart-related chest pain (angina), the enhanced blood flow in the body relaxes the heart muscles by reducing the workload on the heart. It also improves the oxygen flow in the body, thereby, preventing any heart-related chest pain.
