What is glycerin rectal?
Glycerin rectal is used as a laxative. It works by causing the intestines to hold more water, which softens the stool.
Glycerin rectal is used to treat occasional constipation or to cleanse the bowel before a rectal exam or other intestinal procedure.
Glycerin rectal may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

To make sure glycerin rectal is safe for you, tell your doctor if you have:
a change in bowel habits that has lasted for 2 weeks or longer;
ulcerative colitis, toxic megacolon; or
if you have used another laxative for longer than 1 week.

How should I use glycerin rectal?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Overuse of a laxative may cause damage to the nerves, muscles, or tissues in your intestines.
Do not take a rectal suppository by mouth. It is for use only in your rectum.
Wash your hands before and after using a rectal enema or suppository.
This medicine comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
To use the suppository:
Remove the wrapper before inserting the suppository. Avoid handling the suppository too long or it will melt in your hands.
Use your finger or the applicator provided to insert the suppository.
Lie on your left side with your lower leg straight and your upper leg bent. Gently insert the suppository pointed tip first into your rectum, about 1/2 inch for a child or 1 inch for an adult.
For best results, stay lying down for a few minutes. The suppository will melt quickly and you should feel little or no discomfort while holding it in.
To use the enema:
Remove the protective shield before inserting the enema tip.
Lie on your left side with your lower leg straight and your upper leg bent. If giving this medicine to a child, have the child kneel on the floor and then lower the chest forward until the side of the child's face is resting on the floor.
Gently insert the tip of the applicator or bulb syringe into the rectum, pointing it toward your navel (belly button). Do not force the applicator into the rectum or injury could result.
Slowly squeeze the bottle or bulb until it is nearly empty.
For best results after using glycerin rectal, stay lying down until you feel the urge to have a bowel movement. This medicine should produce a bowel movement within 15 to 60 minutes after using the suppository.
Do not use glycerin rectal more than once in a 24-hour period.
Call your doctor if this medication does not cause you to have a bowel movement within 1 hour after use.
Store the rectal enema at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
Store the rectal suppositories at cool room temperature away from moisture and heat. Some suppositories can be refrigerated. Check your medicine label to be sure how to store your medicine.
What happens if I miss a dose?
Since glycerin is usually given only once as needed, you will not be on a dosing schedule. Do not use glycerin rectal more than once in a 24-hour period.
What happens if I overdose?
An overdose of glycerin rectal is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.
What should I avoid while using glycerin rectal?
Avoid using other laxatives in combination with glycerin rectal unless your doctor has told you to.
