In some cases, your doctor may ask you to perform an enema before you come in for a procedure like a colonoscopy.
Purchase distilled water, as tap water may contain contaminants that you don’t want to introduce into your rectum. If you’re making a homemade enema solution, you’ll also need to purchase an enema bag and tube. Do not add any other ingredients to the saline solution unless your doctor advises you to. Even if you see them recommended online or by your family and friends, do not put fruit juices, herbs, vinegar, coffee, or alcohol into your enema. The risks posed by introducing these substances into your colon far outweigh any potential benefits.

Do not give an enema to children under the age of 2 unless directed to do so by your doctor.
Typically, store-bought enemas come in children’s and adult’s sizes. Read the label carefully to ensure you get the right enema for your age and body size. Small children and older adults should not be given phosphate enemas, because they can lead to a dangerous electrolyte imbalance.

If you’re using a phosphate enema, the dose is 1 fluid ounce (30 ml) for children who weigh 20 pounds (9. 1 kg) or more, 2 fluid ounces (59 ml) for children who weigh at least 40 pounds (18 kg), 3 fluid ounces (89 ml) for someone who weighs 60 pounds (27 kg) or more, 4 fluid ounces (120 ml) for anyone 80 pounds (36 kg) lb, and 4. 5 fluid ounces (130 ml) if the person weighs 90 pounds (41 kg) or more.
If you’d like, you can also spread a little of the lubricant around your rectal area.
Make sure there’s a place nearby where you can place the enema bag while you wait, like a small stool or a hook you can hang it from. You may also want to have a book or magazine nearby so you’ll have something to read while you’re performing the enema.
If lying on your back is difficult, you can lie on your left side. Choose whichever position is more comfortable for you. It may help to use a hand mirror so you can see what you’re doing better.

This may feel a little uncomfortable, but it shouldn’t be painful. The nozzle tip should be rounded to make it easier to insert. If you’re giving the enema to a child, only insert it 1 1⁄2–2 in (3. 8–5. 1 cm) into their rectum.

Many people find that this helps the nozzle go into their rectum easier.
If you’re using a disposable enema, you may need to squeeze the contents of the container into your rectum. If that’s the case, do this slowly, and be sure to empty the entire bag.
Try to think about how much better you’ll feel after the enema is done.
It may help if you have something to distract yourself during this time, like a book, some music, or a game on your phone. If you experience any cramping, lower the bag slightly, which will slow the flow of the solution.
You may have a bowel movement at this time, but it’s okay if you don’t. It’s a good idea to stay close to the toilet for the next hour or so, as you may have another bowel movement during that time. After an hour, though, you’re free to resume your normal activities. You may experience stomach cramps for a short while after having the enema. If you feel a little faint or dizzy after your enema, lie down until the feeling passes.
If you used a disposable enema kit, you can throw all of the equipment away when you’re finished. [18] X Research source
