Calan SR (Verapamil SR) is a prescription medication used to treat high blood pressure (hypertension) and severe chest pain (angina). Verapamil is also used to control heart rates in a patient with a fast and irregular heartbeat (such as atrial fibrillation). The active ingredient in Calan SR is Verapamil. Verapamil belongs to a class of drugs known as Antidysrhythmic IV, calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

• Certain types of heart rhythm problems (such as second- or third-degree atrioventricular block, sick sinus syndrome unless you have a pacemaker, Wolff-Parkinson-White syndrome);
• Kidney problems;
• Liver problems;
• Muscle and nerve disorders (muscular dystrophy, myasthenia gravis)

Tell your doctor about all your medications, including prescriptions, over-the-counter medications, herbal products, and vitamin supplements.
