Administration: Oral
Administer with water. Swallow tablet whole; do not break, chew, or crush; do not administer within 1 hour of antacids, milk, or dairy products.
Bariatric surgery: Tablet, delayed release: Some institutions may have specific protocols that conflict with these recommendations; refer to institutional protocols as appropriate. Do not cut or crush in order to avoid gastric irritation.
Administration: Rectal

Medication Safety Issues
Sound-alike/look-alike issues:
Warnings/Precautions
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC, 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors, 2001); avoid or use dosage forms containing benzyl alcohol derivative with caution in neonates. See manufacturer’s labeling.
Other warnings/precautions:
• Appropriate use: Tablets: Do not chew or crush; do not use if you cannot swallow without chewing. Do not administer within 1 hour after taking an antacid, milk, or any dairy products.
• Appropriate use: Enema/Suppositories: For rectal use only, discontinue use and consult a health care provider if rectal bleeding occurs or if no bowel movement is produced after use.
• Self-medication (OTC use): Consult a health care provider prior to use if stomach pain, nausea, vomiting, or a sudden change in bowel movements lasting >2 weeks occurs, or if you have already used a laxative, including bisacodyl, for >1 week. Use may cause stomach discomfort, faintness, rectal burning, and mild cramps. Discontinue use and consult a health care provider if use >1 week is needed.
* See Cautions in AHFS Essentials for additional information.
Geriatric Considerations
The chronic use of stimulant cathartics is inappropriate and should be avoided; although constipation is a common complaint from elderly, such complaints require evaluation; elderly are often predisposed to constipation due to disease, drugs, immobility, and a decreased fluid intake, partially because they have a blunted “thirst reflex” with aging; short-term use of stimulants is best; if prophylaxis is desired, this can be accomplished with bulk agents (psyllium), stool softeners, and hyperosmotic agents (sorbitol 70%); stool softeners are unnecessary if stools are well hydrated, soft, or “mushy”.
Pregnancy Considerations
Systemic exposure following maternal use of bisacodyl is limited. Plasma concentrations of BHPM (the active metabolite of bisacodyl) are low (median: 61 ng/mL; range: 20 to 118 ng/mL) and the pharmacokinetics are highly variable following oral doses of 10 mg/day for 7 days to women immediately postpartum (Friedrich 2011).
Use of bisacodyl should be limited during pregnancy due to an increased risk of adverse events, such as electrolyte abnormalities. When dietary changes and lifestyle modifications are insufficient, agents other than bisacodyl are recommended for the treatment of constipation in pregnant women (Body 2016; Gomes 2018).
Breast-Feeding Considerations
It is not known if bisacodyl is present in breast milk.
Systemic exposure following maternal use is limited. Neither bisacodyl nor its active metabolite (BHPM) were detectable in breast milk following administration of bisacodyl 10 mg once daily for 7 days to eight breastfeeding women (lower limit of detection: 1 ng/mL) (Friedrich 2011).
Briggs' Drugs in Pregnancy & Lactation
Adverse Reactions
<1%: Abdominal cramps (mild), electrolyte disturbance (metabolic acidosis or alkalosis, hypocalcemia), nausea, rectal irritation (burning), vertigo, vomiting
* See Cautions in AHFS Essentials for additional information.
Allergy and Idiosyncratic Reactions
Metabolism/Transport Effects
None known.
Drug Interactions Open Interactions
Antacids: May diminish the therapeutic effect of Bisacodyl. Antacids may cause the delayed-release bisacodyl tablets to release drug prior to reaching the large intestine. Gastric irritation and/or cramps may occur. Management: Antacids should not be used within 1 hour before bisacodyl administration. Risk D: Consider therapy modification
Dichlorphenamide: Laxatives may enhance the hypokalemic effect of Dichlorphenamide. Risk C: Monitor therapy
Polyethylene Glycol-Electrolyte Solution: Bisacodyl may enhance the adverse/toxic effect of Polyethylene Glycol-Electrolyte Solution. Risk C: Monitor therapy

Mechanism of Action
Stimulates peristalsis by directly irritating the smooth muscle of the intestine, possibly the colonic intramural plexus; alters water and electrolyte secretion producing net intestinal fluid accumulation and laxation
Pharmacodynamics/Kinetics
Onset of action: Oral: 6 to 12 hours; Rectal: 0.25 to 1 hour (suppository), 5 to 20 minutes (enema)
Half-life: BHPM: ~8 hours (Friedrich 2011)
Distribution: Vd: BHPM: 289 L (after multiple doses) (Friedrich 2011)
Metabolism: Bisacodyl is metabolized to an active metabolite (BHPM) in the colon; BHPM is then converted in the liver to a glucuronide salt (Friedrich 2011)
Absorption: Oral, rectal: Systemic, <5% (Wald 2003)
Excretion: BHPM: Urine, bile (Friedrich 2011)
