Using an enema can be uncomfortable, but it doesn't have to be. The first step is to prepare your space, laying down a towel to catch any liquid that may spill from the enema as it drains into your colon. Next, wash your hands. You'll also want to be close to the toilet in case you need to use it afterward. Finally, lie down in one of the insertion positions recommended on the bottle -- either lie on your left side with your right knee pulled up to your chest or, if you find it more comfortable, get into a kneeling position, leaning forward until the left side of your face is resting on the surface and your left arm is folded comfortably.
Once in a comfortable position, gently insert the enema tip into your anus. This can be easier if you have lubricated your anus with petroleum jelly. It's also sometimes helpful to bear down like you are having a bowel movement, which helps relax the muscles in your abdomen. Gently push the enema bottle into your anus until it feels full, but do not force the tip into the rectum as this can cause injury.
After a few minutes the Fleet Saline Enema will begin to drain into your colon. It will add water and soften your stool so you can pass it. It's important to drink plenty of fluids afterward to prevent dehydration, particularly if you have kidney or heart problems or if you take medications that affect your sodium levels.
