What It's For & How To Take
Polyethylene glycol is an osmotic laxative that is used to treat constipation. This medication increases water retention in the stool which results in a softer stool and more frequent bowel movements. This medication appears to have little or no effect on the absorption of electrolytes from the gastrointestinal tract.
Polyethylene glycol is available as both a prescription and over-the-counter medication. The strength of the medication is the same. The difference is, over-the-counter polyethylene glycol is for the occasional treatment of constipation and is not to be used on a regular basis. When using the over-the-counter form of polyethylene glycol, read the instructions on the label, so you know when you need to consult your pharmacist or doctor for follow-up treatment instructions.
Polyethylene glycol is usually used once daily or as directed by your doctor. This medication is available in both pre-measured packets and a bulk bottle. When using the bulk bottle, the cap of the bottle is used as the measuring device.
Mix your dose of polyethylene glycol in 4-8 ounces of fluid such as water or juice. Stir the solution until all the powder has dissolved in the liquid before drinking the mixture. It may take up to 4 days of daily dosing before you experience a bowel movement. Do not increase your dose or take it more frequently unless directed to do so by your doctor.
If your doctor has prescribed you to take this medication daily and you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
