Side Effects

Clinical Studies Experience

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. The HalfLytely and 5 mg Bisacodyl Tablet Bowel Prep Kit population was 29-87 years of age, 49% male, 51% female, 13% African American, 83% White, 5% Hispanic requiring a colonoscopy. The demographics of the comparator group were similar.

 Postmarketing Experience

The following adverse reactions have been identified during post approval use of HalfLytely and Bisacodyl Tablet Bowel Prep Kit. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Allergic Reactions

Cases of urticaria, rhinorrhea, dermatitis and anaphylactic reactions have been reported with PEG-based products.

Gastrointestinal

There are isolated reports of serious post-marketing events following the administration of PEG-based products in patients over 60 years of age. These adverse reactions include upper GI bleeding from a Mallory-Weiss tear, esophageal perforation, asystole, and acute pulmonary edema after vomiting and aspirating the PEG-based solution. In addition, during administration of 4 liters of PEG-3350 colon cleansing preparation the following serious adverse reactions were seen: two deaths in end stage renal failure patients who developed diarrhea, vomiting and dysnatremia [see WARNINGS AND PRECAUTIONS].

Ischemic colitis has been reported with use of HalfLytely and 20 mg and 10 mg Bisacodyl Tablets Bowel Prep Kit for colon preparation prior to colonoscopy. However, a causal relationship between these ischemic colitis cases and the use of HalfLytely and Bisacodyl Tablet Bowel Prep Kit has not been established.

Neurologic

There have been reports of generalized tonic-clonic seizures associated with use of large volume (4 liter) PEG-based colon preparation products in patients with no prior history of seizures. Cases of dizziness and syncope have been reported [see WARNINGS AND PRECAUTIONS].

Interactions

Drugs That May Increase Risks of Fluid and Electrolyte Abnormalities

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 prolonged QT in the setting of fluid and electrolyte abnormalities. Consider additional patient evaluations as appropriate [see WARNINGS AND PRECAUTIONS] in patients taking these concomitant medications.

Potential for Altered Drug Absorption

Oral medication administered within one hour of the start of administration of HalfLytely solution may be flushed from the GI tract and the medication may not be absorbed completely.

Interaction with Antacids

Do not take the bisacodyl delayed-release tablet within one hour of taking an antacid.

Warnings

Included as part of the PRECAUTIONS section.

Precautions

Serious Fluid and Serum Chemistry Abnormalities

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]

Seizures

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.

Renal Impairment

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.

Cardiac Arrhythmias

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.

Ischemic Colitis

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.

Patients with Significant Gastrointestinal Disease

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.

Aspiration

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.

Patient Counseling Information

See Medication Guide

  • Ask patients to let you know if they have trouble swallowing or are prone to regurgitation or aspiration.
  • Tell patients not to take other laxatives while they are taking HalfLytely and Bisacodyl Tablet Bowel Prep Kit.
  • Tell patients that if they experience severe bloating, distention or abdominal pain, the administration of the solution should be slowed or temporarily discontinued until the symptoms abate. Advise patients to report these events to their health care provider.
  • Advise patients that if they have hives, rashes, or any allergic reaction, they should discontinue the medication and contact their health care provider. Medication should be discontinued until they speak to their physician.
  • Instruct patients to contact their healthcare provider if they develop signs and symptoms of dehydration. [see WARNINGS AND PRECAUTIONS].
  • Inform patients that oral medication administered within one hour of the start of administration of HalfLytely solution may be flushed from the GI tract and the medication may not be absorbed completely.

Use In Specific Populations

Pregnancy

Pregnancy Category C animal reproduction studies have not been conducted. It is not known whether HalfLytely and Bisacodyl Tablet Bowel Prep Kit can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. HalfLytely and Bisacodyl Tablet Bowel Prep Kit should be given to a pregnant or nursing woman only if clearly needed.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when HalfLytely and Bisacodyl Tablet Bowel Prep Kit is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients has not been established.

Geriatric Use

Of the 148 patients who took HalfLytely and 5 mg Bisacodyl Tablet Bowel Prep Kit in clinical trials, 42 (28%) were 65 years of age or older, while 10 (7%) were 75 years of age or older. The rates of success appear to be lower in patients 65 years and older [see Clinical Studies].

OverDose

Using more than the recommended dosage of bisacodyl in conjunction with HalfLytely solution increases the frequency of common adverse events and may increase the risk of ischemic colitis [see WARNINGS AND PRECAUTIONS].

ContrainDications

The HalfLytely and Bisacodyl Tablet Bowel Prep Kit is contraindicated in the following conditions:

  • Gastrointestinal (GI) obstruction
  • Bowel perforation
  • Toxic colitis and toxic megacolon
  • Gastric retention
  • Ileus

Clinical Pharamacology

Mechanism of Action

Polyethylene glycol (PEG), which is an osmotic agent, causes water to be retained within the gastrointestinal tract.

Bisacodyl is hydrolyzed by intestinal brush border enzymes and colonic bacteria to form an active metabolite [bis-(p-hydroxyphenyl) pyridyl-2 methane; (BHPM)] that acts directly on the colonic mucosa to produce colonic peristalsis.

Pharmacodynamics

The stimulant laxative effect of bisacodyl, together with the osmotic effect of the unabsorbed PEG when ingested with a large volume of water, produces watery diarrhea.

Pharmacokinetics

When taken orally, PEG 3350 is minimally absorbed.

Bisacodyl, which is a prodrug, is converted to its active metabolite BHPM by intestinal brush border enzymes and colonic bacteria. The pharmacokinetics of bisacodyl following oral administration of the bisacodyl tablet has not been adequately characterized.

Clinical Studies

The colon cleansing efficacy of HalfLytely and Bisacodyl Tablet Bowel Prep Kit (with 5 mg of bisacodyl) was evaluated in a randomized, single blind (endoscopist only), active-controlled, multicenter study. In this study, 293 adult patients were included in the efficacy analysis. Patients ranged in age from 19 to 87 years old (mean age 55 years old) with 55% female and 45% male patients. Race was distributed as follows: 83% White, 12% African American, 8% Hispanic or Latino, and 4% other.

Patients were randomized to one of the following two colon preparations: 1) HalfLytely and Bisacodyl Tablets (sodium chloride-sodium bicarbonate and potassium chloride) Bowel Prep Kit [10 mg of bisacodyl tablets were given at noon on the day before colonoscopy followed by 2 liters of HalfLytely (after the first bowel movement or maximum of 6 hours)] at a rate of 8 ounces every 10 minutes and 2) a modified HalfLytely and Bisacodyl Tablet Bowel Prep Kit [containing a 5 mg bisacodyl tablet given at noon on the day before colonoscopy followed by 2 liters of HalfLytely (after the first bowel movement or maximum of 6 hours)] at a rate of 8 ounces every 10 minutes.

Patients were instructed to refrain from solid food and to have clear liquids on the day before colonoscopy. In addition, patients were instructed to consume nothing by mouth, except clear liquids, from the time the preparation was completed until after the colonoscopy was completed.

The primary efficacy endpoint was the proportion of patients with successful colon cleansing (assessed by the colonoscopists), see Table 2 below. Successful colon cleansing was defined as preparations that were graded excellent (no more than small bits of adherent feces/fluid) or good (small amounts of feces or fluid not interfering with the exam) by the colonoscopist.

Table 2: Proportion of Patients with Successful Colon Cleansing

View Enlarged Table

The proportion of patients with successful colon cleansing was similar between treatment groups. No differences in response rates by gender or race were noted in the HalfLytely and 5 mg bisacodyl group. In patients ≥ 65 years of age treated with the HalfLytely and 5 mg Bisacodyl Tablet Bowel Prep Kit the proportion with successful colon cleansing was 67% (n=28/42)[ 95% CI: ( 50.5, 80.4)].

This medicine comes in a kit containing 2 bisacodyl delayed-release tablets and a bottle of PEG-3350 with electrolytes in powder form.

Bisacodyl delayed-release tablets:

Do not crush, chew, or break the bisacodyl delayed-release tablets. Swallow the tablets whole with a glass of water. Breaking the pill would cause too much of the drug to be released at one time.

You should have a bowel movement within 1 to 6 hours after taking the bisacodyl tablets. After your first bowel movement, start using the PEG-3350 and electrolyte solution.

Polyethylene glycol 3350 and electrolyte solution:

The PEG-3350 and electrolyte powder must be mixed with water before you take it. Fill the container with water up to the 2-liter mark. Place the cap on the bottle and shake it until the powder is completely dissolved.

A variety of flavor packs are provided with the PEG-3350 powder. Use only one pack to add flavor to the solution. You may also prepare the solution without a flavor pack. Do not add any extra flavorings such as sugar, honey, artificial sweetener, fruit juices, or other beverages.

Shake the liquid well just before you measure each dose. The usual dose of PEG-3350 solution is 8 ounces every 10 minutes. Drink the solution in the exact portions at the exact time intervals prescribed by your doctor.

Drink each portion as quickly as possible, rather than sipping it slowly. The first watery stool should appear within 1 hour after you start drinking the PEG-3350 and electrolyte solution.

You may store the mixed solution in a refrigerator but you must use it within 48 hours after mixing. Throw away any PEG-3350 solution you have not used within 48 hours after it was mixed.

PEG-3350 will produce watery diarrhea. Keep drinking the solution until you have consumed all 2 liters.
