(dil tye' a zem)
- Teczem®(as a combination product containing Diltiazem, Enalapril)¶
WHY is this medicine prescribed?
Diltiazem is used to treat high blood pressure and to control angina (chest pain). Diltiazem is in a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart.
HOW should this medicine be used?
Diltiazem comes as a tablet, an extended-release (long-acting) tablet, and an extended-release capsule to take by mouth. The regular tablet is usually taken three or four times a day. The extended-release capsule and tablet are usually taken one or two times a day. Ask your pharmacist if you should take diltiazem with or without food, because instructions may vary with each product. Take diltiazem at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take diltiazem exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release capsules and tablets whole; do not chew or crush them.
Your doctor will probably start you on a low dose of diltiazem and gradually increase your dose, not more than once every 7 to 14 days if you are taking the extended-release tablet or capsule and not more than once every 1 to 2 days if you are taking the regular tablet.
If taken regularly, diltiazem may control 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.
Diltiazem controls high blood pressure and chest pain (angina) but does not cure them. It may take up to 2 weeks before you feel the full benefit of diltiazem. Continue to take diltiazem even if you feel well. Do not stop taking diltiazem without talking to your doctor.
Are there OTHER USES for this medicine?
Diltiazem is also sometimes used to treat certain types of arrhythmias (abnormal heart rhythms). Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
