PEG-3350 with Electolytes Disease Interactions

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

The use of polyethylene glycol (PEG) solutions is contraindicated in patients with gastrointestinal obstruction, perforation, or toxic megacolon. If gastrointestinal obstruction or perforation is suspected, appropriate studies should be performed prior to administration of these agents. Use with caution in patients with severe active ulcerative colitis. Increased activity of the gut caused by these agents could worsen these conditions.

The use of ionic osmotic laxative products for bowel preparation has been associated with rare reports of serious arrhythmias. Use caution when prescribing PEG electrolyte solutions in patients at increased risk of arrhythmias (e.g., patients with a history of prolonged QT, uncontrolled arrhythmias, recent myocardial infarction, unstable angina, congestive heart failure, or cardiomyopathy). Clinical monitoring of cardiovascular status is recommended prior to, during, and after therapy.

Patients with impaired gag reflex, unconscious or semi-conscious patients, and patients prone to regurgitation or aspiration should be administered polyethylene glycol (PEG) electrolyte solutions cautiously. Patients experiencing severe bloating, distention or abdominal pain may need to receive PEG electrolyte solutions at a slower rate.

Use caution when prescribing PEG electrolyte solutions to patients with impaired renal function or patients taking concomitant medications that may affect renal function. Ensure adequate hydration and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients.

PEG electrolyte solutions have been associated with seizure activity, and/or loss of consciousness. The seizure cases were associated with electrolyte abnormalities and low serum osmolality. Therapy with these agents should be administered cautiously in patients with a history of or predisposition to seizures or in patients with known or suspected hyponatremia.
