Polyethylene glycol 3350, sodium bicarbonate, sodium chloride, and potassium chloride

4 CONTRAINDICATIONS PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution is contraindicated in the following conditions: Gastrointestinal (GI) obstruction, ileus, or gastric retention Bowel perforation Toxic colitis or toxic megacolon Known allergy or hypersensitivity to any component of PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution [see How Supplied/Storage and Handling] Gastrointestinal (GI) obstruction, ileus, or gastric retention ( 4 , 5.6 ) Bowel perforation ( 4 , 5.6 ) Toxic colitis or toxic megacolon Known allergy or hypersensitivity to components of PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution ( 4 , 11 ) 5 WARNINGS AND PRECAUTIONS Risk of fluid and electrolyte abnormalities, arrhythmias, seizures and renal impairment– assess concurrent medications and consider testing in some patients ( 5.1 , 5.2 , 5.3 , 5.4 ) Patients with renal insufficiency– use caution, ensure adequate hydration and consider testing Suspected GI obstruction or perforation – rule out the diagnosis before administration ( 4 , 5.6 ) Patients at risk for aspiration – observe during administration Not for direct ingestion – dilute and take with additional water 5.1 Serious Fluid and Serum Chemistry Abnormalities Advise patients to hydrate adequately before, during, and after the use of PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution.

Fluid and electrolyte disturbances can lead to serious adverse events including cardiac arrhythmias, seizures and renal impairment. Fluid and electrolyte abnormalities should be corrected before treatment with PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution. In addition, use caution when prescribing PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution for patients who have conditions, or who are using medications, that increase the risk for fluid and electrolyte disturbances or may increase the risk of adverse events of seizure, arrhythmias, and renal impairment [see Drug Interactions] . 5.2 Cardiac Arrhythmias There have been rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation.

The neurologic abnormalities resolved with correction of fluid and electrolyte abnormalities. Use caution when prescribing PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution for patients with a history of seizures and in patients at increased risk of seizure, such as patients taking medications that lower the seizure threshold (e.g., tricyclic antidepressants), patients withdrawing from alcohol or benzodiazepines, or patients with known or suspected hyponatremia. 5.4 Renal Impairment Use caution when prescribing PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution for patients with impaired renal function or patients taking concomitant medications that may affect renal function (such as diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or non-steroidal anti-inflammatory drugs).

Administration Instructions Prior to Dosage On the day prior to the colonoscopy, instruct patients to: a. Take only clear liquids, but avoid red and purple liquids. Patients may consume a light breakfast. b. Early in the evening prior to colonoscopy , fill the supplied container containing the PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution powder with lukewarm water (to facilitate dissolution) to the 4 liter fill line.

The solution is clear and colorless when reconstituted to a final volume of 4 liters. c. After capping the container, shake vigorously several times to ensure that the ingredients are dissolved. When reconstituted use within 48 hours.

Dosage The following is the recommended dose of reconstituted PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution for adults and pediatric patients ≥ 6 months. Instruct patients they may consume water or clear liquids during the bowel preparation and after completion of the bowel preparation up until 2 hours before the time of the colonoscopy.

The solution is more palatable if chilled prior to administration.

Adults: Instruct patients to drink a total of up to 4 liters at a rate of 240 mL (8 oz.) every 10 minutes, until 4 liters are consumed or the rectal effluent is clear. Rapid drinking of each portion is preferred to drinking small amounts continuously. For NGT, rate is 20-30 mL per minute (1.2 – 1.8 liters per hour).

Pediatric Patients ≥ 6 Months: Pediatric patients should drink 25 mL/kg/hour until the stool is watery, clear, and free of solid matter. If pediatric patients are unable to drink the reconstituted PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution, the solution may be given by nasogastric (NGT).

NGT administration is at the rate of 25 mL/kg/hour. The first bowel movements should occur approximately one hour after the start of PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution administration. Continue drinking until the watery stool is clear and free of solid matter.
