    Uses

    Verapamil is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Verapamil belongs to a class of drugs known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily.

    Verapamil is also used to prevent chest pain (angina). It may help to increase your ability to exercise and decrease how often you may get angina attacks. Verapamil is also used to control your heart rate if you have a fast/irregular heartbeat (such as atrial fibrillation). It helps to lower the heart rate, helping you to feel more comfortable and increase your ability to exercise.

    How to use Calan

    Take this medication by mouth with or without food as directed by your doctor, usually 3 or 4 times daily.

    The dosage is based on your medical condition and response to treatment.

    Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.

    For the treatment of high blood pressure, it may take a week before you get the full benefit of this drug. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
