Why it is Prescribed
Verapamil is used to treat irregular heartbeats (arrhythmias) and high blood pressure. It relaxes your blood vessels so your heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart to control chest pain (angina). If taken regularly, verapamil controls chest pain, but it does not stop chest pain once it starts. Your doctor may give you a different medication to take when you have chest pain. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Verapamil comes as a regular tablet and as an extended-release (long-acting) tablet and capsule to take by mouth. ...

How it Works
Verapamil comes as a regular tablet and as an extended-release (long-acting) tablet and capsule to take by mouth. The regular tablet is usually taken three times a day. The extended-release tablet and capsule are usually taken one or two times a day and should be swallowed whole. Do not chew, divide, or crush the extended-release tablet or capsule. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take verapamil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Verapamil controls arrhythmias, high blood pressure, and chest pain (angina) but does not cure them. Continue to take verapamil even if you feel well. Do not stop taking verapamil without talking to your doctor.
Other Information
Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to verapamil. Your doctor may ask you to check your pulse (heart rate) daily and will tell you how fast it should be. If your pulse is slower than it should be, call your doctor for directions on taking verapamil that day. Ask your doctor or pharmacist to teach you how to check your pulse. The extended-release tablet (Covera) does not dissolve in the stomach after being swallowed. It slowly releases medicine as it passes through the small intestines. It is not unusual to see the tablet shell eliminated in the stool. Do not let anyone else take your medication. ...
