Sachets de colestyramine

About colestyramine

Colestyramine is a powder which works in the body as a bile acid sequestrant. This means that it binds to bile acids in your digestive system. It prevents bile acids from being reabsorbed (recycled) into your body, and this action can be useful in a number of different conditions.

You may be prescribed colestyramine sachets to help lower the amount of cholestérol in your blood, or to reduce itching caused by a problem in your bile ducts (such as primary biliary cirrhosis), or to help reduce diarrhée caused by certain medical conditions or treatments.

When it is prescribed to lower cholesterol, by preventing the bile acids from being reabsorbed, your liver has to make more bile acids, which it does by using cholesterol from your blood. This lowers the amount of cholesterol in your blood and reduces your risk of blood vessel disease.

When colestyramine is prescribed for itching or diarrhoea, it helps to control your symptoms by reducing the amount of bile acids in your blood.

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 colestyramine it is important that your doctor knows:

• Si vous êtes enceinte, essayez d'avoir un bébé ou allaitez.

• If you are taking other medicines, including those available to buy without a prescription, as well as herbal and complementary medicines.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about colestyramine and will provide you with a full list of the side-effects which you may experience from taking it.

• Take the sachets exactly as your doctor tells you to. It is usual to be prescribed one or two sachets to take each day to begin with. Depending upon your symptoms, your doctor may slowly increase the number of sachets until you are taking 3-6 sachets daily. The maximum dose is nine sachets daily. You may need to take all your sachets as one dose or as separate doses up to four times a day.

• The powder from each sachet should be added to at least 150 ml of water. Allow the mixture to stand for 1-2 minutes, and then stir it well. If you prefer, you can also mix colestyramine with skimmed milk, soup, fruit juice or fruit smoothies. Do not take the powder without mixing it into some liquid first.

• If you forget to take a dose, take it as soon as you remember. Try to take the correct number of sachets each day.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You may need to have blood tests from time to time.

• Avoid taking any other medicines at the same time as you take colestyramine because it can stop the other medicines from being absorbed by your body. Either take your other medicines at least an hour before you take colestyramine, or wait until 4-6 hours after taking colestyramine before you take the other medicines. If you have any problems planning when to take your medicines, speak with your doctor or pharmacist for advice.

• Treatment with colestyramine is often long-term. Continue to take it unless you are advised otherwise.

• Taking colestyramine over a period of time may reduce your body's absorption of fat-soluble vitamins (vitamins A, D and K) and folic acid. Your doctor may advise you to take a supplement containing these vitamins.

• If you have been prescribed colestyramine to lower cholesterol, your doctor may give you advice about lifestyle changes that could help you get the most out of your treatment. This may include reducing the amount of salt in your diet, stopping smoking, losing weight, reducing the amount of alcohol you drink, and taking regular exercise. Following this advice will help you to reduce your risk of developing heart and blood vessel disease in the future.

• Si vous subissez une opération ou un traitement dentaire, informez la personne qui effectue le traitement des médicaments que vous prenez.

• If you buy any medicines 'over-the-counter', check with a pharmacist that they are suitable for you to take.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with colestyramine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Si vous ressentez d'autres symptômes que vous pensez être dus au médicament, parlez-en à votre médecin ou à votre pharmacien pour obtenir des conseils supplémentaires.

• Gardez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.
