High and Low Phosphate Enema Treatment

There are two types:

• Low phosphate enema – the medicine is placed just inside the rectum.
• High phosphate enema – the medicine is given higher into the bowel (sigmoid/descending colon) using a soft tube.

Your child’s doctor will decide which type is best based on your child’s needs.

Why it is needed?

The enema is usually given when other treatments, such as oral laxatives or smaller rectal medicines (e.g. suppositories or mini-enemas), have not worked well enough. It helps relieve constipation, tummy pain, and discomfort caused by a blocked bowel.

What preparation is needed?

Your child will be seen by the doctor beforehand to explain the procedure and answer any questions.

No special preparation is usually needed, but light meals and good fluid intake before the appointment are advised.

It helps to explain gently to your child that the treatment may feel a little uncomfortable but should not hurt. Bringing a toy, blanket, or comfort item can help them relax. A lubricant will be applied to your child’s rectum for the ease of passing the tube.

How long does it take?

The procedure itself only takes a few minutes.

Your child will usually be asked to lie on their left side with knees bent while the enema is given.

Afterward, your child will be asked to stay lying down for around 30 minutes if possible, then use the toilet when they feel the urge.

Bowel movements may continue for up to an hour after the enema.

Is there any risk?

High phosphate enemas are generally safe when given by trained staff.

Some children may have mild tummy cramps, nausea, or discomfort around the bottom. These usually settle quickly.

Rarely, changes in body salts (electrolytes), dehydration, or allergic reactions can occur.

Your child will be closely monitored during and after the procedure to ensure their safety.

If your child becomes unusually unwell after going home, please contact your doctor or go to the nearest emergency department.
