Interactions with Dietary Supplements

Potassium and other nutrients
Prolonged and frequent use of stimulant laxatives, including bisacodyl, may cause excessive and unwanted loss of water, potassium, and other nutrients from the body.¹ ² Bisacodyl should be used for a maximum of one week, or as directed on the packet label. Excessive use of any laxative can cause depletion of many nutrients. In order to protect against multiple nutrient deficiencies, it is important to not overuse laxatives.³ People with constipation should consult with their doctor or chemist before using bisacodyl.

Interactions with Foods and Other Compounds

Food
Bisacodyl tablets are enteric coated to pass through the stomach and dissolve in the small intestine. Milk, dairy products, vegetables, almonds, chestnuts, and other foods can cause the enteric coating to dissolve in the stomach, leading to irritation and cramping.⁴ People should take bisacodyl one hour before or two hours after meals to avoid this problem.
