About ispaghula husk
|Type of medicine||Bulk-forming laxative|
|Also called||Fybogel® and Fybogel® Orange
Fybogel® Mebeverine (ispaghula husk with mebeverine)
|Available as||Effervescent granules or powder in sachets|
Constipation is a common problem. It means either going to the toilet less often than usual to empty your bowels, or passing hard or painful stools. Constipation may be caused by not eating enough fibre or not drinking enough fluids. Pregnancy, a lack of exercise or movement (such as being ill in bed) and some medicines, including some painkillers, can also cause constipation. Sometimes, however, the cause of the constipation is not clear.
Often, increasing the amount of fibre in your diet (such as by eating more fruit, vegetables, cereals, and wholemeal bread) and drinking plenty of water each day can effectively prevent or relieve constipation. You will have been given ispaghula husk for constipation if you cannot increase the fibre in your diet or if this is insufficient. Ispaghula husk works by increasing the bulk of your stools, which encourages your bowels to move the stools through your digestive system, which in turn relieves constipation.
This bulking action means that it can also be used to help treat diarrhoea and to help regulate the passage of food through the digestive system in people with certain long-term bowel disorders, such as irritable bowel syndrome, haemorrhoids, diverticular disease, ulcerative colitis and after some bowel surgery.
Ispaghula husk may sometimes be used in a combination preparation with mebeverine. Mebeverine is an antispasmodic which is used to relieve spasms in the bowel.
Before taking ispaghula husk
Before taking ispaghula husk make sure your doctor or pharmacist knows:
- If you find it difficult to swallow.
- If you are so constipated that you think you may have a blockage.
- If you are pregnant or breast-feeding. (Ispaghula husk may be used during pregnancy or breast-feeding, but it is important that your doctor or pharmacist knows about this.)
- If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to this or to any other medicine.
How to take ispaghula husk
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about the specific brand of ispaghula husk you have been given, and any possible side-effects from taking it.
- Take ispaghula husk exactly as you have been told to. Your doctor or pharmacist will tell you how much to take and when to take it. Your dose will also be on the label of the pack.
- Stir your dose of ispaghula husk granules or powder into a glass of water and then drink it as soon as possible.
- It is best if you take each dose of ispaghula husk just after a meal. Do not take ispaghula husk at bedtime.
- Ispaghula should not be taken by children unless it is on the advice of a doctor or a healthcare professional experienced in the management of constipation in children. Check the label carefully to make sure you are giving the correct dose for the age of 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.
Getting the most from your treatment
- Sometimes 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 your symptoms are improving, or if they get worse, speak with your doctor.
- It is important to drink plenty while you are taking ispaghula husk. You 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 whole-grain 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 that contain sorbitol in your diet. 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.

|Possible ispaghula husk side-effects||What can I do if I experience this?|
|Flatulence (excess wind), bloating, abdominal discomfort||As you become used to the extra fibre, these effects will settle down|
If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.
