Please also refer to the manufacturer's information supplied with your medicine.
The usual dose is 3-6 tablets taken twice a day. Break up the tablets in your mouth before you swallow.
If you are taking methylcellulose for constipation, drink plenty of water as you take the tablets.

About methylcellulose
نوع الدواء | A bulk-forming laxative |
يستخدم لـ | To manage bowel function (constipation and diarrhoea) |
يُعرف أيضًا باسم | Celevac® (UK - discontinued) |
متوفر كـ | أقراص |
Methylcellulose is a laxative used to regulate bowel function - it can help manage constipation or diarrhoea.
الإمساك 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 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. When taken with a glassful of water, methylcellulose tablets absorb the water and swell to a soft gel consistency in your bowel. This increases the bulk of your stools and eases constipation by encouraging your bowels to move the stools through your digestive system.
Methylcellulose tablets can also be helpful to manage الإسهال. When the tablets are swallowed with only a sip of water, they absorb water from the bowel. This helps prevent the loss of fluid from diarrhoea and changes the consistency of the stools making them more formed. This action helps to regulate the passage of food through the digestive systems in people with certain bowel disorders, such as متلازمة القولون العصبي, مرض الرتوج, and التهاب القولون التقرحي, and after some types of bowel surgery.
Before taking methylcellulose
العودة إلى المحتوياتSome 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 methylcellulose it is important that your doctor knows:
If you are pregnant or breastfeeding. Methylcellulose is not considered harmful to babies, but it is important that your doctor knows about this.
If you have any difficulty in swallowing.
إذا كنت تعاني من الإمساك لدرجة أنك تعتقد أنك قد تكون لديك انسداد.
If you have been told you have a bowel infection.
إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.
إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

How to take methylcellulose
العودة إلى المحتوياتBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about methylcellulose and will provide you with a full list of the side-effects which you may experience.
Take methylcellulose tablets exactly as your doctor tells you to. It is usual to take a dose of 3-6 tablets, twice a day. Your doctor will tell you what dose is right for you. Break up the tablets in your mouth before you swallow them. You should not take a dose just before bedtime.
If you are taking methylcellulose for constipation, it is important for you to drink plenty of water at the same time as you take the methylcellulose tablets. Count out the correct number of tablets for your dose and swallow these with a large glassful (about 300 ml) of water.
If you are taking methylcellulose for diarrhoea, swallow the correct number of tablets for each dose with just a sip of water. Avoid drinking anything else during the half hour before you take the tablets and during the half hour after you have taken the tablets.
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.
تحقيق أقصى استفادة من علاجك
العودة إلى المحتوياتThe following information applies if you are taking methylcellulose tablets for الإمساك:
Sometimes it may take a few days before you feel the full benefit from a bulk-forming laxative such as methylcellulose. However, if after several days you do not feel that your symptoms are improving, or if they get any worse, you should speak with your doctor again.
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 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.
You can read more about how to prevent or treat constipation in the separate leaflets called الإمساك (for adults) and Constipation in Children.
