About ispaghula husk
Typ av medicin | A bulk-forming laxative |
Används för | Förstoppning |
Även kallad | Psyllium husk (in US); Fybogel®; Ispagel®; Fybogel Hi-Fibre®; ourFIBRE® |
Tillgänglig som | Granules in sachets |
Förstoppning is a common problem which can be caused by a number of things. Not eating enough fibre or not drinking enough fluid can cause constipation. Some conditions (such as pregnancy) can cause constipation, as can a lack of exercise or movement (such as being ill in bed) and some medicines.
Often, increasing the amount of fibre (bran) in your diet and drinking plenty of water each day can effectively prevent or relieve constipation. You will have been recommended ispaghula husk to help relieve constipation if you cannot increase the amount of fibre in your diet, or if this is insufficient. Ispaghula husk, a laxative, works by increasing the bulk of your stools, which encourages your bowels to move the stools through your digestive system, in turn relieving constipation.
Sachets containing granules of ispaghula husk are available on prescription, and can also be bought without a prescription at pharmacies and other retail outlets.
Before taking ispaghula husk
Tillbaka till innehållTo make sure this is the right treatment for you, ask for advice from a doctor or pharmacist before you start using ispaghula husk if any of the following apply to you:
If you are pregnant, trying for a baby or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
If it is for a child. This is because laxatives should only be given to children on the advice of a doctor or healthcare professional.
If you have any problems with the way your kidneys work or you are on a potassium-controlled diet.
If you have any difficulty in swallowing.
If you are so constipated that you think you may have a blockage.

How to take ispaghula husk
Tillbaka till innehållBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about ispaghula husk and will provide you with a full list of the side-effects which you may experience.
Take ispaghula husk exactly as your doctor tells you to, or as directed on the pack. The usual dose for an adult is one sachet taken twice a day. Pour the granules from the sachet into a glass of water (about 150 ml), stir well, and then drink the liquid as soon as possible.
It is best if you take your doses just after a meal. Never take a dose at bedtime.
If a doctor or healthcare professional has recommended ispaghula husk for your child, check the label on the pack carefully to make sure that you give the correct dose for the age of your child. Remember to stir the granules into a glass of water before giving the mixture to your child.
If you forget to take a dose, do not worry, just take the next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Få ut det mesta av din behandling
Tillbaka till innehållSometimes it may take a few days before you feel the full benefit from a bulk-forming laxative such as ispaghula husk. However, if after several days you do not feel that your symptoms are improving, or if they become any worse, you should speak with a doctor.
It is important to drink plenty while you are taking ispaghula husk. Adults should aim to drink at least two litres (about 8-10 cups) of fluid per day. Most sorts of drink will do, but as a start, try just drinking a glass of water 3-4 times a day in addition to what you normally drink.
Try to eat a balanced diet containing high-fibre foods such as wholemeal and wholegrain breads and cereals, fruit and vegetables, brown rice and wholemeal pasta. If you are not used to a high-fibre diet, it may be best to increase the amount of fibre you eat gradually.
Keeping your body active will help you to keep your digestive system moving, so try to take some regular daily exercise.
You may wish to include some foods in your diet that contain sorbitol. Sorbitol is a naturally occurring sugar. It is not digested very well and draws water into your bowel which has an effect of softening stools. Fruits (and their juices) that have a high sorbitol content include apples, apricots, gooseberries, grapes (and raisins), peaches, pears, plums, prunes, raspberries and strawberries.
You can read more about how to prevent or treat constipation in the separate leaflets called Förstoppning (for adults) and Förstoppning hos barn.
