Methylcellulose

About methylcellulose

Methylcellulose works by absorbing water and swelling to a soft gel consistency. It is used to treat constipation and to help regulate the passage of food through the gut in people with certain chronic (long term) bowel disorders.

Constipation is when the stools that are passed are hard and less frequent than normal. It can be caused by a poor diet, not drinking enough water and not going to the toilet as soon as needed. Pregnancy, a lack of exercise or movement (such as being ill in bed) and some medicines, including some pain killers, can also cause constipation.

Methylcellulose can also be used to treat diarrhoea. It works by absorbing water in the bowel and producing a more solid stool consistency.

Before taking methylcellulose

Before taking methylcellulose make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If you have difficulty swallowing.
• If you are so constipated that you may be suffering from a blockage.
• If you have a bowel infection.
• If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
• If you have ever had an allergic reaction to this or any other medicine.

How to take methylcellulose

• Before beginning treatment, read the manufacturer's printed information leaflet.
• Take methylcellulose exactly as directed by your doctor. Never take a dose just before bedtime.
• If you are taking methylcellulose for constipation, swallow your dose with a large glass (300ml) of water. It is important for you to drink plenty of water at the same time as taking methylcellulose.
• If you are taking methylcellulose for diarrhoea, the tablets should be swallowed with only a small amount of water and drinks should be avoided for half an hour before and after taking the tablets. It is important that you drink plenty of water for the rest of the day to prevent dehydration due to lost fluids.

Getting the most from your treatment

• You may need to take methylcellulose for some days before you feel the full effect.
• For people who have problems with constipation, food such as pastries, puddings, sugar, sweets, cheese and cake can make matters worse. Try to eat a well balanced diet containing fibre (whole grain breads and cereals, bran, fruit and green leafy vegetables) and drink 6 to 8 full glasses of water each day. Daily exercise is also important in maintaining healthy bowel function.
• Drinks containing caffeine (tea, coffee, colas) or alcohol can make constipation worse as they have a diuretic effect, which means they cause a loss of fluid from the body, causing dehydration.
