Advise all patients to hydrate adequately before, during, and after the use of HalfLytely and Bisacodyl Tablet Bowel Prep Kit. If a patient develops significant vomiting or signs of dehydration after taking HalfLytely and Bisacodyl Tablet Bowel Prep Kit, consider performing post-colonoscopy lab tests (electrolytes, creatinine, and BUN). Fluid and electrolyte disturbances can lead to serious adverse events including cardiac arrhythmias, seizures and renal impairment.
Patients with electrolyte abnormalities should have them corrected before treatment with HalfLytely and Bisacodyl Tablet Bowel Prep Kit. In addition, use caution when prescribing HalfLytely and Bisacodyl Tablet Bowel Prep Kit for patients with 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 (7.1) ]
There have been reports of generalized tonic-clonic seizures with the use of large volume (4 liter) PEG-based colon preparation products in patients with no prior history of seizures. The seizure cases were associated with electrolyte abnormalities (e.g., hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia) and low serum osmolality. The neurologic abnormalities resolved with correction of fluid and electrolyte abnormalities.
Use caution when prescribing the HalfLytely and Bisacodyl Tablet Bowel Prep Kit for patients with a history of seizures and in patients at risk of seizure, such as patients taking medications that lower the seizure threshold (e.g., tricyclic antidepressants), patients withdrawing from alcohol or benzodiazepines, patients with known or suspected hyponatremia, or patients using concomitant medications (such as diuretics) that increase the risk of electrolyte abnormalities. Monitor baseline and post-colonoscopy laboratory tests (sodium, potassium, calcium, creatinine, and BUN) in these patients.
Patients with impaired water handling who experience severe vomiting should be closely monitored including measurement of electrolytes (sodium, potassium, calcium, BUN and creatinine). Use caution when prescribing HalfLytely and Bisacodyl Tablet Bowel Prep Kit 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). Advise these patients of the importance of adequate hydration and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients.
There have been rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation. Use caution when prescribing HalfLytely and Bisacodyl Tablet Bowel Prep Kit for 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). Pre-dose and post-colonoscopy ECGs should be considered in patients at increased risk of serious cardiac arrhythmias.
There have been reports of ischemic colitis in patients with use of HalfLytely and 20 mg Bisacodyl Tablets Bowel Prep Kit and HalfLytely and 10 mg Bisacodyl Tablets Bowel Prep Kit. If patients develop severe abdominal pain or rectal bleeding, patients should be evaluated as soon as possible.
If gastrointestinal obstruction or perforation is suspected, perform appropriate diagnostic studies to rule out these conditions before administering HalfLytely and Bisacodyl Tablet Bowel Prep Kit.
Use with caution in patients with severe active ulcerative colitis.
Use with caution in patients with impaired gag reflex and patients prone to regurgitation or aspiration. Such patients should be observed during administration of the HalfLytely and Bisacodyl Bowel Prep Kit solution.
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice.
In a clinical study of HalfLytely and (5 mg vs. 10 mg) Bisacodyl Tablets Bowel Prep Kit overall discomfort, abdominal fullness, abdominal cramping, nausea, and vomiting, were the most common adverse reactions (>3%). The data in Table 1 reflects the 154 patients that received HalfLytely and 5 mg bisacodyl tablet vs. the 154 patients that received HalfLytely and 10 mg bisacodyl tablets.
