What is Rowasa rectal?
Rowasa affects a substance in the body that causes inflammation, tissue damage, and diarrhea.
Rowasa may also be used for purposes not listed in this medication guide.
Before taking this medicine
You should not use Rowasa if you are allergic to it.
To make sure Rowasa is safe for you, tell your doctor if you have:
It is not known whether Rowasa will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether mesalamine passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.
How should I use Rowasa rectal?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not take rectal medicine by mouth. It is for use only in your rectum.
For best results, use Rowasa at bedtime. Try to empty your bowel and bladder just before using the medicine.
Wash your hands before and after inserting the rectal suppository.
Remove the wrapper before inserting the suppository. Avoid handling the suppository too long or it will melt in your hands. Lie on your back with your knees up toward your chest. Gently insert the suppository into your rectum about 1 inch, pointed tip first.
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. Avoid using the bathroom for at least an hour after using the suppository.
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.
For best results, try to hold in the enema for at least 30 minutes, or all night if possible, to allow the liquid to distribute throughout your intestines. Avoid using the bathroom during this time.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Store at cool room temperature away from moisture and heat.
The rectal 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 extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using Rowasa rectal?
