What symptom does docusate sodium primarily help alleviate?

Docusate sodium is a stool softener that primarily aids in alleviating constipation. It works by increasing the amount of water and fat absorbed into the stool, making it softer and easier to pass. This is particularly beneficial for individuals who may be experiencing hard or difficult-to-pass stools due to various factors such as dehydration, certain medications, or a diet low in fiber. It does not address headaches, acid reflux, or allergies, which are managed by other classes of medications. Therefore, the focus of docusate sodium's therapeutic action is specifically on promoting bowel regularity and easing discomfort associated with constipation.
