Wash your hands before and after using rectal medicine.
Remove the wrapper before inserting the suppository. Avoid handling the suppository too long or it will melt. Lie on your back with your knees up toward your chest. Gently insert the suppository into your rectum about 1 inch, pointed tip first.
Stay lying down for a few minutes while the suppository melts. You should feel little or no discomfort. Avoid using the bathroom for at least an hour.
Shake the rectal enema liquid well just before each use.
To use the enema, lie on your left side with your left leg extended and your right leg slightly bent. Remove the cap from the applicator tip and gently insert the tip into your rectum. Slowly squeeze the bottle to empty the contents into the rectum.
After using the enema, lie down on your left side for at least 30 minutes to allow the liquid to distribute throughout your intestines. Avoid using the bathroom, and hold in the enema at least 1 hour, or all night if possible.
It may take up to 3 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.
Store at cool room temperature away from moisture and heat.
