What is Sorbitol for?
Sorbitol is a natural humectant (moisturizing agent) and sweetener commonly found in food, beverages and medications. Sorbitol is also used as a laxative to treat constipation. It works by drawing water from the gut and softening stools, therefore stimulating bowel movement and relieving constipation. Sorbitol is also used as an irrigation solution to irrigate the bladder and urinary tracts, or as an intravenous solution with mannitol to maintain osmotic pressure in the body.
How to use it?
Sorbitol solution may be taken orally or inserted as an enema rectally to stimulate bowel movement. Enema works directly in the rectum and is more effective than oral solution.
If you use an oral solution, take 2 to 3 tablespoons by mouth whenever necessary. It normally takes 12 to 72 hours for Sorbitol to work when taken orally.
If you use the enema, shake well before opening the protective shield. Lie down and squeeze the enema content into your rectum. Remain lying for a couple of minutes before sitting or standing. You may feel the urge to go to the toilet in 15-60 minutes. Do not eat, chew or swallow the enema or use it in any other way. Wash your hands thoroughly before and after using enema.
For bladder irrigation, the procedure will be performed in a medical setting by your doctor. A catheter will be inserted through the urinary tract into the bladder, and the bladder will be flushed with Sorbitol solution to clean out the inside.
What are the side effects of Sorbitol?
Common side effects of Sorbitol include dehydration, burning sensation or discomfort in anus or rectum.
