DULCOLAX 5 mg coated tablets
DULCOLAX adults 10 mg suppositories
Bisacodyl
What it is and what it is used for
Dulcolax contains bisacodyl. It belongs to a group of medicines called contact laxatives.
Dulcolax works by stimulating bowel movements, speeding up the passage of bowel contents.
Dulcolax is used in adults, children and adolescents between 2 and 18 years of age for the short-term treatment of occasional constipation.
Contact your doctor if you do not feel better or if you feel worse after 7 days.
What you need to know before taking the medicine
Do not take/give your child Dulcolax
- if you and/or your child are allergic to bisacodyl or any of the other ingredients of this medicine (listed in paragraph 6);
- if you and/or your child suffer from an arrest of the progression of intestinal content due to a blockage of the intestinal musculature (paralytic ileus);
- if you and/or your child suffer from acute abdominal conditions, such as inflammation of the appendix, a part of the intestine (appendicitis), and severe abdominal pain associated with nausea and vomiting that may be indicative signs of serious diseases;
- if you and/or your child suffer from intestinal obstruction or narrowing (intestinal stenosis);
- if you and/or your child suffer from acute inflammation of the stomach and intestine;
- if you and/or your child suffer from rectal bleeding of unknown origin;
- if you and/or your child suffer from severe loss of water from the body (dehydration);
- if you and/or your child suffer from a hereditary disease that may be incompatible with taking one of the excipients (see paragraph 2. Dulcolax contains lactose and sucrose);
- if your child is under 2 years of age;
- if you and/or your child suffer from anal fissures and ulcers, do not take/give your child suppositories (pain and perianal bleeding may occur).
If you are pregnant or breastfeeding, see the Pregnancy and breastfeeding paragraph.
Warnings and precautions
Contact your doctor or pharmacist before taking/giving your child Dulcolax.
Cases of dizziness and/or fainting (syncope) have been reported after taking Dulcolax. The data relating to these cases suggest that the events, rather than a phenomenon related to the assumption of Dulcolax, could be interpreted as a manifestation of fainting (syncope) from defecation (attributable to the effort of the act of defecation), or as a reflexive response to abdominal pain related to constipation itself.
The use of suppositories can lead to painful sensations and local irritation, in particular, in the presence of fissures and inflammatory bowel disease of the rectum (ulcerative proctitis) (see paragraph 2 Do not take/give your child Dulcolax).
Like all laxatives, do not take/give your child Dulcolax daily or for prolonged periods without your doctor having first evaluated the cause of constipation. The treatment of chronic or recurrent constipation always requires the intervention of a doctor for diagnosis, prescription of medicines and monitoring during therapy.
In particular, consult your doctor:
• when the need for the laxative results from a sudden change in previous bowel habits (frequency and characteristics of bowel movements) that has lasted for more than two weeks or when the use of the laxative fails to produce effects;
• if you are elderly or in poor health;
• if you/your child suffer from diabetes mellitus, high blood pressure (hypertension) or heart disease (cardiopathy).
Laxative abuse
The abuse of laxatives (frequent or prolonged use or with excessive doses) can cause persistent diarrhoea with consequent fluid loss (dehydration) or a decrease in blood potassium levels (hypokalemia).
In the most severe cases, a decrease in potassium can cause heart or muscle disorders, especially if you are undergoing concomitant treatment with some heart medications (cardiac glycosides), with drugs that increase urine production (diuretics) or with those used to treat inflammation (corticosteroids).
Symptoms of intestinal fluid loss (dehydration) can be thirst and reduced elimination of urine quantity (oliguria).
Fluid loss (dehydration) can be dangerous if you/your child suffer from reduced kidney function (renal insufficiency) or if you are elderly; therefore, discontinue treatment with Dulcolax and consult your doctor.
The presence of blood in the faeces (hematochezia) may also occur, which is generally mild and resolves spontaneously.
Avoid frequent or prolonged use of the medicine as it can lead to addiction and dependence (i.e. the need to progressively increase the dosage and not be able to do without the medicine), as well as chronic constipation and loss of normal bowel function (intestinal atony).
Stimulant laxatives including Dulcolax do not contribute to weight loss.

In children aged between 2 and 10 years, the medicine can only be used after consulting a doctor.
Dulcolax should not be used in children under two years of age.
