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
Oral, rectal: Systemic, <5% (Wald, 2003)
Bisacodyl is metabolized to an active metabolite (BHPM) in the colon; BHPM is then converted in the liver to a glucuronide salt (Friedrich, 2011)
BHPM: Urine, bile (Friedrich, 2011)
Onset of Action
Oral: 6-10 hours; Rectal: 0.25-1 hour; Vd: BHPM: 289 L (after multiple doses) (Friedrich, 2011)
BHPM: ~8 hours (Friedrich, 2011)

Administer tablet with a glass of water on an empty stomach for rapid effect. To protect the enteric coating, tablet should not be administered within 1 hour of milk, any dairy products, or taking an antacid. Do not chew or crush tablets.
To protect the enteric coating, tablet should not be taken within 1 hour of milk, any dairy products, or taking an antacid. Should be administered with a glass of water on an empty stomach for rapid effect.
Store enteric-coated tablets and rectal suppositories at <30°C.
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. Consider therapy modification
<1% (Limited to important or life-threatening): Abdominal cramps (mild), electrolyte disturbance (metabolic acidosis or alkalosis, hypocalcemia), nausea, rectal irritation (burning), vertigo, vomiting
Plasma concentrations of BHPM (the active metabolite of bisacodyl) are low (median: 61 ng/mL; range: 21-194 ng/mL) following doses of 10 mg/day for 7 days (Friedrich, 2011). Although not first choice for the treatment of constipation in pregnant women, short-term use of stimulant laxatives is generally considered safe in pregnancy; long-term use should be avoided (Cullen, 2007; Prather, 2004; Wald, 2003).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience abdominal cramps or rectal irritation. Have patient report immediately to prescriber severe dizziness, passing out, or severe abdominal pain (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

You must ultimately rely on your own discretion, experience and judgment in diagnosing, treating and advising patients.
