How does Senokot work? What will it do for me?

Senna belongs to the class of medications called stimulant laxatives. It is used to relieve occasional constipation that is not caused by other medications or medical conditions. This medication works by increasing the muscle activity in the digestive system, causing waste material to be eliminated as stool. It usually produces a stool between 6 and 12 hours after taking the medication.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Are there any other precautions or warnings for Senokot?

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 is taken for too long a period of time, it may cause diarrhea and affect the levels of fluid and electrolytes in the blood. 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 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 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 within 2 hours of any other medications.

Overuse of medication: As with any stimulant laxative, ongoing use of senna may cause the bowel to become dependent on the medication to produce stools. Unless your 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.

Breast-feeding: This medication is considered safe to use while breast-feeding, however it should only be used when recommended by a doctor.

Children: The safety and effectiveness of using this medication have not been established for children less than 2 years of age. Consult a health care professional before giving this medication to children between the ages of 2 and 5 years.
