sod phos mono-sod phos dibasic oral Uses
This medication is used to clean out the intestines before a colonoscopy. Sodium phosphate is a laxative that works by drawing large amounts of water into the colon, causing you to have watery bowel movements. This cleans out the intestines so that your doctor can clearly view them during your colonoscopy.
Read the Medication Guide provided by your pharmacist before you start taking this medication and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Your doctor should tell you how long before the procedure you should take this product. Follow your doctor's directions closely. If you are uncertain about any of the information, consult your doctor or pharmacist.
Follow any special dietary instructions given by your doctor. A period of not eating is usually recommended before you start taking this medication and lasting until after the colonoscopy. Only clear liquids (such as water, flavored water, lemonade with no pulp, ginger ale, apple juice) are allowed during this time. Do not drink any liquids colored purple or red.
The evening before your colonoscopy, take 4 tablets with at least 8 ounces (240 milliliters) of clear liquid by mouth every 15 minutes or as directed by your doctor. Repeat this dose and the liquids every 15 minutes until you have taken 5 doses (20 tablets). The next day, start taking the medication 3-5 hours before the colonoscopy. Take 4 tablets every 15 minutes with liquids as directed until you have taken 3 doses (12 tablets).
Dosage is based on your medical condition, procedure, and response to treatment. Do not use a higher dose or more often than directed by your doctor.
Do not use any other laxative products (especially sodium phosphate) while taking this product or for 7 days after treatment is finished. Doing so may increase your risk for severe side effects.
Watery bowel movements usually begin 1 hour after you start to take the tablets. The bowel movements can be very large and watery. Drink as many clear liquids as you can before, during, and after taking this medication so that you do not lose too much body water (become dehydrated). Doing so will help prevent serious side effects (such as kidney problems). Consult your doctor or pharmacist for more information.
The watery bowel movements from sodium phosphate may decrease the absorption of your regular medicines. Consult your doctor or pharmacist about how to minimize this effect.
Contact your doctor if you do not have a bowel movement within 3 hours after taking this medication.
