1. What Adizem-XL capsules are and what they are used for

These capsules have been prescribed for you to treat angina (chest pain caused by a reduction of oxygen to the heart muscle) or high blood pressure (hypertension). They contain the active ingredient diltiazem. Diltiazem belongs to a group of medicines called calcium antagonists. Calcium antagonists help more blood to reach the heart and reduce blood pressure. The other ingredients of Adizem-XL capsules are listed in section 6 of this leaflet.

Adizem-XL capsules are designed to work properly over 24 hours. If the capsules are crushed or chewed, the entire 24-hour dose may be absorbed rapidly into your body. This can be dangerous, causing serious problems such as an overdose.

3. How to take Adizem-XL capsules

Always take Adizem-XL capsules exactly as your doctor has told you. The label on your medicine will tell you how many capsules to take and how often.

The usual starting dose for adults is one 240 mg capsule every 24 hours. However, if you are elderly or have kidney problems then your doctor will probably suggest a lower starting dose of one 120 mg capsule every 24 hours. Your doctor will decide how many capsules you should take.

Children should not take these capsules.

Do not exceed the dose recommended by your doctor. You should check with your doctor or pharmacist if you are not sure.

Swallow your capsules whole with a glass of water. Do not chew or crush the capsules.

You should take your capsules every 24 hours. For instance, if you take a capsule at 8 o’clock in the morning, you should take your next capsule at 8 o’clock the next morning.

If you take more Adizem-XL capsules than you should or if someone accidentally swallows your capsules

Call your doctor or hospital straight away. People who have taken an overdose may become very unwell, feel faint, have a slow heart beat and lose consciousness. They may need emergency treatment in hospital. When seeking medical attention make sure that you take this leaflet and any remaining capsules with you to show to the doctor.

If you forget to take Adizem-XL capsules

If you remember within 4 hours of the time your capsule was due, take your capsule straight away. Take your next capsule at your normal time. If you are more than 4 hours late, please call your doctor or pharmacist for advice. Do not take a double dose to make up for a forgotten capsule.

If you stop taking Adizem-XL capsules

You should not stop taking these capsules unless your doctor tells you to. If you want to stop taking your capsules, discuss this with your doctor first.

If you have any further questions on the use of Adizem-XL capsules ask your doctor or pharmacist.
