What Dilzem® is used for
The name of your medicine is Dilzem. It contains the active ingredient called diltiazem hydrochloride.
Dilzem 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.
Dilzem is used to prevent angina.
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.
Your doctor may have prescribed Dilzem for another reason. Ask your doctor if you have any questions about why Dilzemhas been prescribed for you.
There is no evidence that Dilzem is addictive.
This medicine is available only with a doctor’s prescription.

How to take Dilzem®
How much to take
Dilzem is usually taken 3 – 4 times a day. Take the prescribed dose as directed by your doctor.
A lower dosage may be required in elderly patients (over 65 years old).
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How to take it
Swallow Dilzem tablets whole with a glass of water.
When to take it
Take Dilzem tablets at the same time each day as directed by your doctor.
How long to take it
Take Dilzem for as long as your doctor tells you to.
Do not stop taking Dilzem suddenly because this can bring on an attack of angina.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose that you missed. If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to casualty at your nearest hospital, if you think that you or anyone else may have taken too much Dilzem. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much Dilzem, you may feel dizzy and light-headed, feel pain in your left arm or chest or notice your heart beating very slowly. If any of these occur you should get medical attention immediately.
While you are using Dilzem®
Things you must do
Use Dilzem exactly as your doctor has prescribed. If you do not follow your doctor's instructions, you may not get relief from your attacks of angina.
Tell your doctor if you continue to have angina attacks or if they become more frequent while you are using Dilzem.
Tell all doctors, dentists and pharmacists who are treating you that you are taking Dilzem.
Tell your doctor or pharmacist that you are taking Dilzem if you are about to be started on any new medicines.
Things you must
Do not use it to treat any other complaints unless your doctor says to.
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
As mentioned previously, do not suddenly stop taking your medicine since this can cause severe angina for a day or two.
Things to be careful of
Be careful driving or operating machinery until you know how Dilzem affects you. Dilzem may cause dizziness and fainting in some patients, especially when you first start to use it. Make sure you know how you react to Dilzem before you drive a car, operate machinery, or do anything else that could be dangerous if this happens to you.
Be careful not to overdo physical activities when you first start using Dilzem. You may feel better when you start taking it, but you will need time to improve your physical fitness.
Get up slowly when getting out of bed or standing up if you feel light-headed, dizzy or faint. If this is a problem and it gets worse or continues, talk to your doctor.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Dilzem. Dilzem helps most people with angina, but it may have unwanted effects in a few people.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
