A saline laxative called Fleet Enema reliably relieves occasional constipation without causing discomfort or spasms. If you have three or fewer bowel motions per week and your stools are firm, dry, and challenging to pass, you may be constipated. In order to soften the stool and facilitate a bowel movement, Fleet Enema increases the amount of water in the intestine. It is perfect for cleaning the bowels prior to a rectal examination.
