Phospho soda

Phospho soda is an over the counter saline laxative consisting mostly of monobasic sodium phosphate monohydrate and dibasic sodium phosphate heptahydrate. It is often taken to prepare for colonoscopy.

An amount of Phospho soda (normally 1.5fluid ounce or 45 ml) is usually mixed with water other clear liquids such as ginger ale. This preparation usually results in a bowel movement anywhere from 30 minutes to 6 hours after it is taken. Phospho soda is also available in flavors to make it more palatable.

Use as a Laxative

Phospho-Soda can be used for a general laxative, but is not recommended. The dosage then is best cut in half and used only once instead of twice.

Phospho-Soda works by drawing liquid from the body into the colon, therefore it can cause severe dehydration if not used properly, and sometimes can even then. Usage in this context is highly recommended to be performed with a doctor's knowledge and consent.

Pre-Colonoscopy Usage

When Phospho-Soda is taken for colonoscopy prep the dose is usually 1.5 fluid ounces, twice in one day (3 oz total) usually 6 hours apart and is to be mixed with equal parts water (or other clear liquid) and then followed by 8 oz water. It will create very loose, {liquid} stool within 1/2 hour to 6 hours, usually about one hour.

A 2007 study showed that in patients with decreased renal function, Phospho soda may worsen renal impairment compared to polyethylene glycol-based laxatives. In patients without kidney problems, no difference was observed.
