Diltiazem

About diltiazem

Diltiazem is used to treat högt blodtryck (hypertoni) and prevent chest pain caused by angina. It works by causing some of your blood vessels to relax and widen. This lowers your blood pressure. It also reduces the force and the rate of your heartbeat, and this helps to prevent angina pain.

Before taking diltiazem

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking diltiazem it is important that your doctor knows:

• Om du är gravid, försöker bli gravid eller ammar.

• If you have any problems with your kidneys or liver.

• If you have a heart condition (such as heart failure, an abnormal heart rhythm, or if you have had a heart attack recently).

• If you have high blood sugar levels (diabetes mellitus).

• If you have asthma or other breathing problems.

• Om du har en sällsynt ärftlig blodsjukdom som kallas porfyri.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• If you have ever had an allergic reaction to this or to any other medicine.

How to take diltiazem

• Before you start taking diltiazem, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about the specific brand of tablet or capsule you have been given, and a full list of side-effects which you may experience from taking it.

• There are several different formulations of diltiazem available, so it is important that you take your tablets or capsules exactly as your doctor tells you to. 'Standard' 60 mg tablets are taken three times daily, whereas longer-acting tablets or capsules are taken once a day or twice a day. Your doctor will tell you which is right for you, and this will also be printed on the label of the pack to remind you.

• Try to take diltiazem at the same times each day, as this will help you to remember to take your doses.

• Swallow the tablets or capsules whole with a drink of water - do not chew, break or crush them. You can take diltiazem before or after food.

• If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

Få ut det mesta av din behandling

• Försök att hålla dina regelbundna möten med din läkare. Detta är så att din läkare kan följa upp din utveckling.

• Your doctor will discuss with you the possibility of unwanted side-effects when you first start taking diltiazem. You may experience headaches, feeling flushed, swollen ankles and some dizziness. These effects usually only last for a few days, but if they continue or become troublesome, you should let your doctor know.

• Different formulations and brands of diltiazem can act in a slightly different way in your body. Because of this, it is important that you continue to take the same type of tablet or capsule as you have had before. So, each time you collect a prescription, check to make sure your supply looks the same and that the brand name is the same. If you are unsure, or if have any questions about your prescription, please ask your pharmacist to check it for you.

• If you have diabetes you may need to check your blood sugar (glucose) level more often. This is because diltiazem may raise your glucose levels. Ask your doctor or pharmacist for advice.

• Before you buy any medicines or take any 'over-the-counter' remedies, please check with a pharmacist that they are suitable for you to take. This is because some medicines can interact with diltiazem.

• Drinking grapefruit juice may affect the amount of diltiazem in your blood and can make you more likely to experience side-effects. Let your doctor or pharmacist know if you enjoy drinking grapefruit juice and wish to continue.

• If you need to have an operation or any medical treatment, always tell the person carrying out the treatment which medicines you are taking. Diltiazem may interfere with the way some anaesthetics work.

• If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on this medicine as it may increase the chance that you experience side-effects, such as feeling dizzy or light-headed.

• Suddenly stopping treatment may cause problems, so keep taking diltiazem unless your doctor tells you otherwise. If it does become necessary for you to stop treatment, your doctor will want you to reduce your dose over a few days.
