Take balsalazide capsules with a meal or after a snack.
It is important that you keep your regular appointments with your doctor so that your progress can be checked. You will need to have regular blood tests.
Common side-effects tend to be minor, but on occasions, balsalazide can cause more serious problems. You should tell your doctor immediately if you have any unexplained bleeding, bruising, red or purple discolorations of your skin, a sore throat, or a high temperature (fever), or if you feel generally unwell.
|Type of medicine||Aminosalicylate|
|Used for||Ulcerative colitis in adults|
Ulcerative colitis causes inflammation of the large intestine. This leads to problems such as ulceration and bleeding, and causes symptoms of abdominal pain and diarrhoea.
Although it is not clear exactly how balsalazide works, it is thought to act on the cells which line your intestine to change the way that they make and release certain chemicals. These chemicals are thought to be a factor in causing the symptoms of ulcerative colitis. Balsalazide allows the damaged areas of your intestine to recover, and then helps to prevent your symptoms from flaring up again at a later date.
Before taking balsalazide
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 balsalazide it is important that your doctor knows:
- If you are pregnant, trying for a baby or breastfeeding.
- If you have any problems with your kidneys or liver.
- If you have asthma.
- If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you have had an unusual reaction to aspirin, or to any other salicylate medicine.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to take balsalazide
- Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about balsalazide and a full list of side-effects which you may experience from taking it.
- Take balsalazide exactly as your doctor tells you to. They will tell you how many capsules to take for each dose, and when to take them. It is likely you will be asked to take three capsules three times a day at first, but your dose will be reduced to two capsules twice daily once your symptoms have improved. The directions will be printed on the label of the pack to remind you how to take the capsules.
- Take balsalazide capsules with a drink of water after a meal or snack. Do not open or chew the capsules.
- 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 forgotten dose. Remember to take your next dose when it is due. Do not take two doses together to make up for a missed dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor and clinic. This is so your doctor can check on your progress. You will need to have regular blood tests during this treatment.
- Treatment with balsalazide may be long-term in order to prevent your symptoms from flaring-up from time to time. Continue to take the capsules unless you are advised otherwise by your doctor.
- Your doctor may advise you to make some changes to your diet as part of your treatment. This may include a special diet or a nutritional supplement.
- If you have an allergic condition, such as asthma, you should let your doctor know straightaway if you find your allergic symptoms get worse. If this happens, your doctor may want to review your treatment or will arrange to see you more often to keep an eye on your progress.
