Docusate calcium

Definition

Docusate calcium is a surfactant stool softener used to relieve constipation by increasing the amount of water the stool absorbs in the gut, making it easier to pass. It is commonly prescribed for patients with conditions that require avoiding straining during bowel movements.

3. Common side effects include stomach cramps, diarrhea, and throat irritation if not taken with enough fluid.
4. Docusate calcium should not be used for longer than one week unless directed by a healthcare provider.
