Start squeezing the enema container to push the liquid into the rectum. Try to empty all of the contents by squeezing from the bottom of the container to the top. Wait for the fluid to enter your rectum, breathing deeply and until the bag is empty. Remove nozzle from your rectum gradually. After the allotted time, evacuate the bowels into the toilet as per instructions of hospital. Stay close to a toilet for the next 30 to 60 minutes as it may be necessary to go to the toilet several times.
