Rectal sodium phosphate is used to treat constipation that happens from time to time. Rectal sodium phosphate should not be given to children younger than 2 years of age. Rectal sodium phosphate is in a class of medications called saline laxatives. It works by drawing water into the large intestine to produce a soft bowel movement.
Rectal sodium phosphate comes as an enema to insert in the rectum. It is usually inserted when a bowel movement is desired. The enema usually causes a bowel movement within 1 to 5 minutes. Follow the directions on the package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use rectal sodium phosphate exactly as directed. Do not use more or less of it or use it more often than directed on the package label. Do not use more than one enema in 24 hours even if you have not had a bowel movement. Using too much rectal sodium phosphate may cause serious damage to the kidneys or heart and possibly death.
Rectal sodium phosphate is available in a regular- and large-size enema for adults and a small-size enema for children. Do not give the adult-size enema to a child. If you are giving the child-size enema to a child who is 2 to 5 years of age, you should give half of the contents. To prepare this dose, unscrew the cap of the bottle and remove 2 tablespoons of liquid using a measuring spoon. Then replace the bottle cap.
Remove the protective shield from the tip of the enema.
Lie down on your left side and raise your right knee to your chest or kneel and lean forward until the left side of your face is resting on the floor and your left arm is comfortably folded.
Gently insert the enema bottle into your rectum with the tip pointing toward your navel. While you insert the enema, bear down as though you are having a bowel movement.
Squeeze the bottle gently until the bottle is nearly empty. The bottle contains extra liquid, so it does not have to be completely empty. Remove the enema bottle from your rectum.
Hold the enema contents in place until you feel a strong urge to have a bowel movement. This will usually take 1 to 5 minutes, and you should not hold the enema solution for more than 10 minutes. Wash your hands after using the enema.
