How should I use sfRowasa rectal?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Do not take a rectal suppository or enema by mouth. Use it only in your rectum.
For best results, use sfRowasa at bedtime. Try to empty your bowel and bladder before using rectal medicine. Read and carefully follow any Instructions for Use provided with your medicine.
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 1 to 3 hours or longer, if possible.
Shake the rectal enema liquid well just before each use.
Drink plenty of liquids while you are using sfRowasa.
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 8 hours, or all night, if possible.
Drink plenty of water each day.
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.
You may need frequent blood tests to check your blood cells or kidney function.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using sfRowasa.
Store at cool room temperature away from moisture and heat.
The enema liquid may darken in color after it has been removed from the foil pouch. This should not affect the medicine. However, throw away any enema liquid that has turned dark brown.
What happens if I miss a dose?
Skip the missed dose and wait until your next bedtime to use the medicine. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
