Dulcolax contraindications and warnings


The following provides information on contraindications to the use of bisacodyl in general, pregnancy & breastfeeding and children. Please note that the contraindications may vary depending on the dosage form of a drug (eg tablet, syringe, ointment).

When should Bisacodyl not be used?

Bisacodyl must not be used with

  • Hypersensitivity to the active substance
  • intestinal obstruction
  • Signs of severe bowel disease such as spasmodic abdominal pain and possibly accompanying nausea and vomiting. In case of such symptoms immediate medical intervention is necessary.
  • acute inflammatory diseases of the gastrointestinal tract, such as appendicitis
  • Disruptions of water and mineral salt equilibrium.

Bisacodyl should only be used after a risk-benefit consideration by a physician and under his control in

  • chronic constipation, as prolonged use may increase the suffering
  • elderly or patients with renal impairment, because both are at particular risk of dehydration, as may be elicited by increased emptying of liquid stool.

What should you watch out for during pregnancy and lactation?

Since the introduction of bisacodyl in 1952, no adverse or damaging effects have been reported during pregnancy. However, no clinical studies have been done. Bisacodyl should therefore only be used on medical advice during pregnancy.

Neither bisacodyl nor any of its breakdown products in the body passes into breast milk. The active ingredient can therefore be used safely during breast-feeding.

What should be considered in children?

Bisacodyl should not be used in children under the age of two years. The dosage should be age-dependent in children.

Warnings and Precautions

  • The drug is for short-term (up to one week) use only.
  • Overdose may cause cramping abdominal pain and diarrhea.
  • In case of diarrhea due to overdose, the water and salt losses must be compensated.
  • Prolonged use may cause the bowel to become sluggish.
  • When taking the drug should be dispensed with simultaneous milk consumption.
  • If you have abdominal cramps, driving a car or operating machinery through dizziness or fainting can be dangerous.

Sometimes medications release allergic reactions.
If you notice any signs of allergic reaction, tell your doctor or pharmacist immediately.
