What Is Dulcolax Pico Liquid?
Dulcolax Pico Liquid contains sodium picosulfate (5 mg per 5 mL), a stimulant laxative that helps relieve occasional constipation.
It works by stimulating the nerve endings in the bowel wall, encouraging natural muscle contractions (peristalsis) that move stool through the colon and help produce a bowel movement.
How Long Does Dulcolax Pico Liquid Take to Work?
Individual response times can vary slightly depending on hydration, diet and digestive function, but most people experience a bowel movement the following morning.
