How does this medication work? What will it do for me?
Docusate sodium belongs to the family of medications known as stool softeners. It is used to treat and prevent occasional constipation due to hard stools. Docusate sodium works by increasing the amount of water in the stool, making stools softer and easier to pass. It usually starts to work within 1 to 3 days, but it may take up to 5 days to work.
