Bisacodyl 5mg Gastro-resistant tablets contain a medicine called bisacodyl. This belongs to
a group of medicines called laxatives.
Bisacodyl is used for relief of constipation.
Bisacodyl can also be used in a hospital to empty a person’s bowel before child birth,
surgery or radiological investigations.
Bisacodyl gently stimulate the muscles of the bowel (large intestine). This brings predictable,
overnight relief from constipation, helping to return the body to its natural rhythm.
Bisacodyl 5mg Gastro-resistant Tablets have a special coating that helps to ensure the
medicine works only where it is needed.

Bisacodyl 5mg Gastro-resistant Tablets do not help with weight loss.
What is constipation?
Normal and regular bowel movement is important for most people. However, what is ‘normal and regular’
varies from person to person. Some may have a bowel movement every day, others less often. Whatever it is
like for you, it is best that your bowel movement has a regular pattern.

Constipation is an occasional problem for some people. For others, it may happen more often.
It happens when the normal muscle actions in the bowel (large intestine) slow down. This can
mean that material is not easily eliminated from the body.

The cause of constipation is often not known. It can be associated with:
• Sudden change of diet
• A diet with not enough fibre
• Loss of ‘tone’ in the bowel muscles in older people
• Pregnancy
• Medicines such as morphine or codeine
• Having to stay in bed for a long time
• Lack of exercise
Whatever the cause, constipation can be uncomfortable. It may make you feel bloated and heavy or generally
‘off colour’. Sometimes it causes headaches.
These healthy tips are recommended to try to prevent constipation happening:
• Eat a balanced diet including fresh fruit and vegetables.
• Drink enough water so that you do not become dehydrated.
• Keep up your exercise and stay fit.
• Make time to empty your bowel when your body tells you.


Do not take Bisacodyl if:
• You are allergic (hypersensitive) to bisacodyl or any of the other ingredients in the product tablets.
(listed in Section 6: Further information).
• You are intolerant to or cannot digest some sugars (as the tablet contains a small amount of
lactose and sucrose).
• You have severe dehydration.
• You have a bowel condition called ‘ileus’ (blockage in the intestine).
• You have a serious abdominal condition such as appendicitis.
• You have severe abdominal pain with nausea and vomiting.
• You have a blocked bowel (intestinal obstruction).
• You have inflammation of the bowel (small or large intestine).
Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or
pharmacist before taking this medicine.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including
medicines obtained without a prescription. This includes herbal medicines. This is because Bisacodyl can
affect the way some other medicines work. Also, some other medicines can affect the way Bisacodyl works.
In particular, tell your doctor or pharmacist if you are taking:
• water tablets (diuretics) such as bendrofluazide or furosemide (frusemide)
• steroid medicines such as prednisolone
• indigestion remedies
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Bisacodyl
5mg Gastro-resistant Tablets.
Pregnancy and breast feeding
Talk to your doctor or pharmacist before taking Bisacodyl if you are pregnant, planning to become pregnant
or are breast feeding. It is not advised to take this medicine whilst breast feeding.
Driving and using machines
Some people may feel dizzy or faint while taking this medicine. If this happens to you, wait until these feelings
go away before driving or using machines.

This medicine contains lactose (a milk sugar) and sucrose. If you have been told by your doctor that you have

Children aged between 4 and 10 years
Bisacodyl 5mg Gastro-resistant Tablets should only be given to children between the ages of 4 and 10 if
recommended by a doctor. The usual dose for children is:
• one tablet (5 mg) daily before bedtime.
Children under 4 years
Bisacodyl 5mg Gastro-resistant Tablets are not recommended for children under 4 years.
Elderly patients:
If you are elderly, you may be prescribed a lower dose.
If you take more Bisacodyl than you should
It may be harmful to:
• take too much bisacodyl
• take bisacodyl for too long
This is because taking too much for too long may lead to:
• A ‘lazy bowel’ where the muscle in the bowel becomes too relaxed. This means that bowel emptying
happens less often. This can lead to long-term constipation.
• Imbalance of fluid and salts in the body. This can affect the tightness of muscles such as those in the
bowel. It can also affect the salts in the blood.
• Low levels of potassium in the blood (called ‘hypo-kalaemia’). This can make you tired, dizzy, make your
muscles weak and cause an uneven heart-beat.
• Dehydration, making you thirsty, feel faint and giving you headaches. It can also mean you cannot pass
enough urine.
If you take more of this medicine than you should, talk to a doctor or go to a hospital straight away. Take the
medicine pack with you; this is so the doctor knows what you have taken.
If you forget to take Bisacodyl
If you have forgotten to take your tablet at night, wait for the next dose and continue as before. Do not take
any more tablets in one day than your doctor has prescribed. Do not take a double dose to make up for a
missed dose.
If you feel that the effect of your medicine is too strong or too weak, talk to your doctor or pharmacist.
If you have any questions on the use of this product, ask your doctor or pharmacist.
