Phosphates Solution is a low-volume, hyper-osmotic agent that you be asked to mix with water as directed and drink it before undergoing a colonoscopy, radiography, or other bowel procedure that requires you to completely empty your bowels in order for a doctor to have a clear view of your entire intestines to check for polyps or other eruptions and possibly take some small tissue samples for further testing.

The ingredients of generic or brand Phosphates Solution are Sodium Phosphate Dibasic/Sodium Phosphate Monobasic, a saline laxative that increases fluid in your intestines so the stool is easier and quicker to pass, usually in 30 minutes to 6 hours. Follow all instructions on mixing and when to start taking Phosphates Solution. The generic alternative is not manufactured by the company that makes the brand product.
