Bisacodyl Levels and Effects while Breastfeeding

Summary of Use during Lactation

Bisacodyl is not absorbed from the gastrointestinal tract, and its active metabolite, which is absorbed, is not detectable in breastmilk. Bisacodyl can be taken during breastfeeding and no special precautions are required.

Drug Levels

Maternal Levels. Sixteen postpartum women who were not breastfeeding, but were producing at least 200 mL of milk daily by breast pump were given either oral enteric-coated bisacodyl tablets (Dulcolax) 10 mg daily or oral liquid sodium picosulfate (Laxoberal) 10 mg daily for 7 days. Both drugs are prodrugs metabolized to the active drug, bis-(p-hydroxyphenyl)-2-pyridyl-2-methane (BHPM). All breastmilk was collected daily from the day before drug administration to 2 days after the last dose. Free and conjugated BHPM were undetectable (<1 mcg/L) in all milk samples.[1]
