Constipation in adults is a common problem. It means either going to the toilet less often than usual to empty the bowels, or passing hard or painful stools when you do go. It can be caused by not eating enough fibre or not drinking enough fluids, or a lack of exercise or movement (such as being ill in bed). It can also be a side-effect of certain medicines (such as some painkillers), or related to an underlying medical condition. In many cases, the cause is not clear.
Lubiprostone helps to increase secretion of fluid into the bowel. This increases the movement of the bowels, making stools easier to pass. It is helpful for people for whom constipation remains a problem despite recommended changes to lifestyle or diet.
Before taking lubiprostone
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 lubiprostone it is important that your doctor knows:
- If you are pregnant or breast-feeding.
- If you are so constipated that you think you may have a blockage.
- If you have any problems with the way your liver works.
- If you have low blood pressure (hypotension).
- If you have ever had an allergic reaction to a medicine.
- If you are taking 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 lubiprostone
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about lubiprostone and a full list of the side-effects which you may experience from taking it.
- Take lubiprostone exactly as your doctor tells you to. The usual dose is one capsule twice daily. A course of treatment lasts for two to four weeks. Swallow the capsule with a drink of water after a meal, or with a snack. The ideal times to take the capsules are after breakfast and after supper.
- If you forget to take a dose, leave out the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Remember to keep any regular appointments with your doctor. This is so your doctor can check on your progress.
- If you have been taking lubiprostone for two weeks and have not noticed any improvement in your symptoms, let your doctor know.
- A healthy diet containing fibre (wholegrain breads and cereals, bran, fruit and green leafy vegetables) with several glasses of water each day and daily exercise are important in maintaining healthy bowel function. For people who have problems with constipation, foods such as pastries, puddings, sugar, sweets, cheese and cake can make matters worse and are best avoided.
