Symptoms: If high doses are taken diarrhoea, abdominal cramps and a clinically significant loss of potassium and other electrolytes can occur. This may also lead to increased sensitivity to cardiac glycosides.
Chronic overdose with laxatives may cause chronic diarrhoea, abdominal pain, hypokalaemia, secondary hyperaldosteronism and renal calculi.
Renal tubular damage, metabolic alkalosis and muscle weakness secondary to hypokalaemia have also been described in association with chronic laxative abuse.
Therapy: Within a short time after ingestion of Bisacodyl tablets, absorption can be minimised or prevented by inducing vomiting. Otherwise, gastric lavage should be performed. Replacement of fluids and correction of electrolyte imbalance (particularly hypokalaemia) may be required. This is especially important in the elderly and the young. Administration of antispasmodics may be of some value.

Pharmacotherapeutic group: Laxatives, ATC code: A06AB02
Bisacodyl is a locally acting laxative of the triarylmethane group, which, after bacterial cleavage in the colon, has the dual action of stimulating the mucosa of both the large intestine causing peristalsis and of the rectum causing increased motility and a feeling of rectal fullness.
The rectal effect may help to restore the “call to stool†although its clinical relevance remains to be established.
Hydrolysis of Bisacodyl by enzymes of the enteric mucosa forms desacetylbisacodyl which is absorbed and excreted partly via urine and bile as glucuronide. By bacterial cleavage the active form, the free diphenol, is formed in the colon. Bisacodyl tablets are resistant to gastric and small intestinal juice, reaching the colon without any appreciable absorption and thereby avoiding enterohepatic circulation. Consequently, Bisacodyl tablets have an onset of action between 6 - 12 hours after administration.
Suppository formulations of bisacodyl have an onset of action within 15 - 30 minutes, although in some cases it may be prolonged to 15 - 60 minutes. The onset of action is determined by the release of the active substance from the preparation.
After administration, only small amounts of the drug are systemically available. Urinary excretion reflects low systemic burden after administration.
There is no relationship between the laxative effect and plasma levels of the active diphenol.

As with all laxatives, Bisacodyl tablets should not be taken on a continuous basis for more than five days.
If laxatives are needed every day, the cause of constipation should be investigated. Prolonged excessive use may lead to fluid and electrolyte imbalance and hypokalaemia, and may precipitate the onset of rebound constipation.
Intestinal loss of fluids can promote dehydration. Symptoms may include thirst and oliguria. In patients suffering from fluid loss where dehydration may be harmful (e.g. renal insufficiency, elderly patients) bisacodyl should be discontinued and only be restarted under medical supervision.
Patients may experience haematochezia (blood in stool) that is generally mild and self-limiting.
Dizziness and /or syncope have been reported in patients who have taken Bisacodyl. The details available for these cases suggest that the events would be consistent with defaecation syncope (or syncope attributable to straining at stool), or with a vasovagal response to abdominal pain related to the constipation, and not necessarily to the administration of bisacodyl itself.
There have been isolated reports of abdominal pain and bloody diarrhoea occurring after taking bisacodyl. Some cases have been shown to be associated with colonic mucosal ischaemia.
Children under 10 years should not take Bisacodyl tablets without medical advice.
Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.
Bisacodyl tablets have no effect on ability to drive and use machinery.
Children aged 10 years or younger with chronic constipation should only be treated under the guidance of a physician. Bisacodyl should not be used in children aged below 2 years of age or younger.
Short-term treatment for constipation:
Adults and children over 10 years:
1 - 2 coated tablets (5 - 10 mg) daily before bedtime, or 1 suppository (10 mg) for immediate effect.
Children 2 - 10 years: 1 coated tablet (5 mg) daily before bedtime, or 1 suppository (5 mg) for immediate effect.
For preparation of diagnostic procedures and preoperatively
Should only be used under medical supervision.
Adults and children over 10 years:
2 coated tablets (10 mg) in the morning and 2 coated tablets (10 mg) in the evening and 1 suppository (10 mg) on the following morning is recommended.
Children 4-10 years of age:
1 coated tablet (5 mg) in the evening and one suppository (5 mg) on the following morning is recommended.
Due to the specific pharmaceutical form of the product from Guerbet (bottle containing a phosphate laxative and 4 (5 mg each) film-coated bisacodyl tablets for use as bowel preparation specifically for adults, the present posology should be maintained (For adults only.
