How To Use:

Remove orange protective shield from enema before inserting.
With steady pressure, gently insert enema tip into rectum with a slight side-to-side movement, with tip pointing toward navel.
Insertion may be easier if person receiving enema bears down, as if having a bowel movement.
This helps relax the muscles around the anus.
Stop using if tip is hard to insert. Forcing the tip into the rectum can cause injury (especially if you have hemorrhoids).
If enema tip causes rectal bleeding or pain, get immediate medical care.
Squeeze bottle until nearly all liquid is gone. It is not necessary to empty the bottle completely, as it contains more liquid than needed.
Remove from rectum and maintain position until urge to evacuate is strong (usually 1 to 5 minutes).

Positions for using this enema:

Left-side position: Lie on left side with knee bent, and arms resting comfortably.
Knee-chest position: Kneel, then lower head and chest forward until left side of face is resting on surface with left arm folded comfortably.
If no urge is felt after 5 minutes of using, try to empty bowel.
Call a doctor promptly if no liquid comes out of the rectum after 30 minutes because dehydration could occur.
The diaphragm at base of nozzle prevents reflux and assures controlled flow of the enema solution.
Enema should be used at room temperature
