Cardizem CD

Cardizem CD (Diltiazem Hydrochloride) capsules contain an active ingredient called diltiazem hydrochloride. They are designed to release the active ingredient slowly so that it works over 24 hours and can be taken once a day (CD stands for "controlled delivery"). The active ingredient in these capsules belongs to a group of medicines called calcium channel blockers or calcium antagonists. They work by opening up blood vessels, which lowers blood pressure and lets more blood and oxygen reach the heart. They do not change the amount of calcium in your blood or bones.

These capsules are used by some people to prevent angina and by others to treat hypertension (high blood pressure). Angina is a pain or uncomfortable sensation in the chest, often spreading to the arms or neck and sometimes to the shoulders and back. The pain of angina is due to a shortage of oxygen to the heart.

High blood pressure can have many different causes including kidney disease, hardening of the arteries and some hormone imbalances. However, the vast majority of people with high blood pressure have no identifiable cause for it. If left untreated, high blood pressure can lead to serious health problems such as a stroke or heart attack.

Cardizem CD capsules can be taken once a day, preferably at the same time every day. Your physician will tell you how often and how much Cardizem CD to take. Follow all directions given to you by your physician and pharmacist carefully. Write them down if necessary. If you do not understand the instructions on the packaging of this medicine, ask your physician or pharmacist for help.

Swallow this medicine with a glass of water. Do not chew the capsule. Take this medicine at the same time every day. If you are not sure how long to take your medicine for, talk to your physician. If you are taking Cardizem CD tablets for angina, do not suddenly stop taking them as this can cause severe angina for a day or two.

Tell your physician or pharmacist as soon as possible if you do not feel well while you are taking Cardizem CD capsules. Cardizem CD capsules help most people with angina or high blood pressure, but they may have unwanted effects in a few people. All medicines can have side effects. Sometimes they are serious, but most of the time they are not. You may need medical treatment if you get some of the side effects.

• swelling or flushing (feeling hot suddenly)

• nausea
• dizziness

• you feel pain, which may be severe, in your left arm and chest

• you have skin reactions such as red, painful or itchy spots, blisters or peeling of the skin

These are serious side effects. You may need urgent medical attention. Serious side effects are rare. Other side effects not listed above may also occur in some patients. Tell your physician if you notice anything else that is making you feel unwell.

If you have an allergic or hypersensitive reaction, seek emergency medical attention. Possible symptoms include difficulty breathing, difficulty swallowing, swelling, chest tightness, skin rashes, and hives.
