Treatment Name: Polyethylene Glycol (MiraLAX®)
Polyethylene Glycol (MiraLAX®) is a Supportive Care Therapy to treat Constipation
How does polyethylene glycol work?
Polyethylene glycol (MiraLAX®) is designed to prevent your intestines from absorbing some of the water you drink. When extra water is kept within the intestines, it softens the stool and stimulates the intestines, which produces a bowel movement.
Goals of therapy:
Polyethylene glycol is taken to relieve occasional constipation. It is commonly taken on an as needed basis with the goal of treating constipation.
Polyethylene glycol (MiraLAX®) is available as an over-the-counter (OTC) medication not requiring a doctor's prescription.
Schedule
Polyethylene glycol (MiraLAX®) is commonly taken at home on an as needed basis to treat constipation and maintain normal, regular bowel movements daily or every other day. When dosed adequately, polyethylene glycol generally induces a bowel movement in approximately one to three days.
Polyethylene glycol (MiraLAX®) powder:
- Fill bottle cap with polyethylene glycol powder to the indicated line (17 grams), then mix with 4 to 8 ounces of any beverage (can be cold, hot or room temperature) until dissolved, then drink beverage. Do not take more than once a day unless instructed by your doctor or pharmacist
Polyethylene glycol powder packets:
- Mix one packet (17 grams) with 4 to 8 ounces of any beverage (can be cold, hot or room temperature) until dissolved, then drink beverage. Do not take more than once a day unless instructed by your doctor or pharmacist
Polyethylene glycol is usually taken at home. Typical duration of therapy is until polyethylene glycol no longer works in relieving constipation, or constipation is resolved and polyethylene glycol is no longer needed. Do not take polyethylene glycol for more than seven days without talking to your doctor.
Store polyethylene glycol (MiraLAX®) at room temperature (68°F – 77°F).
Side Effects
In the prescribing label information (polyethylene glycol (MiraLAX®) package insert), the most commonly reported side effects from polyethylene glycol (MiraLAX®) are shown here:
Note: Nausea or vomiting may also be due to other medications, conditions, or severe constipation rather than polyethylene glycol.
Note: The exact percentages of patients that will experience polyethylene glycol side effects is unknown because it has been used under widely varying patient populations in a variety of clinical trials.
Stop using polyethylene glycol (MiraLAX®) if you have diarrhea, bleeding from the rectum or blood in the stool, or if cramping in the abdomen (belly) gets worse.
Monitoring
How often is monitoring needed?
Labs (blood tests) are usually not necessary to start or continue polyethylene glycol therapy.
How often is imaging needed?
Imaging may be checked if there is concern of a small bowel obstruction (SBO) or blockage. Imaging may include: Abdominal X-ray, or CT scan of the abdomen and pelvis.
How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue polyethylene glycol as planned, add additional laxatives, place you on “bowel rest” (nothing by mouth until the obstruction clears), or switch to an alternative therapy for constipation.
