The capsules may cause a number of side effects such as dizziness and a general feeling of being unwell. These could affect your ability to drive (see section 4 for a full list of side effects) and are usually most noticeable when you start taking the capsules, or when changing to higher dose. If you are affected you should not drive or operate machinery.

This medicine contains less than 1mmol sodium (23mg) per capsule, that is to say essentially ‘sodium-free’.

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.

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

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.

Call your doctor or hospital immediately. People who have taken an overdose may become very unwell and the following effects may happen: feel faint, have a slow heart beat, decrease of kidney function 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 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.

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 get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
