How does this medication work? What will it do for me?
This combination product contains two medications: senna and docusate sodium. Senna belongs to the class of medications called stimulant laxatives. Docusate sodium belongs to the family of medications known as stool softeners. Senna works by increasing the muscle activity in the digestive system, causing waste material to be eliminated as stool. Docusate sodium works by increasing the amount of water in the stool, making stools softer and easier to pass.
This combination medication is used to treat occasional constipation due to hard stools. Specifically, it is recommended for women who have recently given birth; people for whom hard, dry stools should be avoided (e.g., people with hemorrhoids or anal fissures); and people for whom stool straining should be avoided (e.g., people with heart disease). This combination usually produces a stool between 6 and 12 hours after taking the medication.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Fluid and electrolyte balance: If senna - docusate sodium is taken for too long a period of time, it may cause diarrhea and affect the levels of fluid and electrolytes in the body.
If you experience symptoms of fluid and electrolyte imbalance such as thirst, muscle pains or cramps; dry mouth; numb hands, feet, or lips; or racing heartbeat, contact your doctor as soon as possible. Inform your doctor of any medications for heart or blood pressure that you may be taking, as these also increase the risk of fluid and electrolyte changes.
General: If you experience a sudden change in your bowel movements that lasts for 2 weeks or more, do not take this medication without first talking to your doctor. If you take senna - docusate sodium and it does not seem to help with your constipation, or if rectal bleeding occurs, stop using this medication and contact your doctor.
Other medications: Although senna - docusate sodium does not directly affect the actions of other medications, taking it too close to other medications may change how much of the other medication is absorbed by the body. Avoid taking senna - docusate sodium within 2 hours of any other medications.
Overuse of medication: As with any stimulant laxative, ongoing use of senna - docusate sodium may cause the bowel to become dependent on the medication to produce stools. Unless you doctor has recommended a specific schedule, do not take senna for more than 1 week.
Pregnancy: This medication is considered safe to use during pregnancy, however is should only be used when recommended by a doctor. Lower than usual adult doses should be used.
