What is in this leaflet
This leaflet answers some common questions about Cardizem CD capsules and Cardizem tablets.It does not contain all the available information.
It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits.Your doctor has weighed the risks of you taking these medicines against the benefits they expect it will have for you.

What these medicines are used for
You have been prescribed either Cardizem CD capsules or Cardizem tablets.These medicines both contain an active ingredient called diltiazem hydrochloride.The difference between these is that Cardizem CD is 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”).Cardizem tablets release the active ingredient faster and so must be taken more often (3-4 times a day, as your doctor has instructed).
These medicines belong 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.
Cardizem tablets are used to prevent angina.
Cardizem CD capsules are used to prevent angina or 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.
Your doctor may have prescribed these medicines for another reason.
Ask your doctor if you have any questions about why these medicines have been prescribed for you.
There is no evidence that these medicines are addictive.
These medicines are available only with a doctor’s prescription.
