Polyethylene glycol electrolyte solution is a laxative solution that stimulates bowel movements. This medication also contains minerals to replace electrolytes that are passed from the body in the stool.

Polyethylene glycol electrolyte solution is used to clean the bowel before colonoscopy, a barium x-ray, or other intestinal procedures.

Polyethylene glycol electrolyte solution may also be used for purposes not listed in this medication guide.

You should not use this medicine if you are allergic to polyethylene glycol or any other electrolyte solutions (such as Pedialyte or Gatorade), or if you have:

• a perforated bowel;
• a bowel obstruction or severe constipation; or
• colitis or toxic megacolon.

Polyethylene glycol electrolyte solution can cause dangerous or life-threatening side effects in people with these conditions.

People with eating disorders (such as anorexia or bulimia) should not use this medicine without the advice of a doctor.

Tell your doctor if you have ever had:

• heart problems, or a heart attack;
• an electrolyte imbalance (such as low levels of potassium or sodium in your blood);
• kidney disease;
• a seizure;
• gastroesophageal reflux disease (GERD), ulcerative colitis, or other stomach or bowel disorder;
• trouble swallowing, aspiration (accidentally inhaling food or drink);
• a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency; or
• a drug or alcohol addiction.

Tell your doctor if you are pregnant or breast-feeding.

• signs of an electrolyte imbalance--increased thirst or urination, dry mouth, confusion, constipation, muscle pain or weakness, leg cramps, irregular heartbeats, tingly feeling.

You may need to drink the liquid more slowly, or stop using it for a short time if you have certain side effects. Call your doctor for instructions if you have:

• gagging, choking, severe stomach pain or bloating;
• nausea, vomiting, headache, trouble drinking liquids, little or no urinating; or
• fever, sudden or severe stomach pain, severe diarrhea, rectal bleeding or bright red bowel movements.

Common side effects may include:

• vomiting, stomach pain, indigestion, bloating;
• rectal pain or irritation;
• hunger, thirst, mild nausea;
• trouble sleeping; or
• dizziness, chills.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Avoid taking other medications, vitamins, or mineral supplements within 1 hour before drinking polyethylene glycol electrolyte solution. A bowel cleansing can make it harder for your body to absorb other medicines you take by mouth.

Do not use other laxatives while using polyethylene glycol electrolyte solution unless your doctor has told you to.
