Stool softener laxatives are used to treat occasional constipation. They work by drawing water and fat into your stool, making it softer and easier to pass. Stool softener laxatives come in different forms, including oral pills, oral liquids, and rectal enemas. Examples include oral docusate sodium (Colace, Pedia-Lax), and docusate enemas (Enemeez). You can choose the form that best fits your needs.
