Cautions
Caution with increased incidence of elevated serum electrolytes, serum creatinine, and BUN
Caution in patients with renal impairment or patients taking concomitant medications that may affect renal function; patients may be at risk for renal injury; advise patients of importance of adequate hydration before, during and after use of product and consider performing baseline and post-colonoscopy laboratory tests
Seizures: Reports of generalized tonic-clinic seizures with use of bowel preparations products; associated with electrolyte abnormalities (eg, hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia); caution in patients at risk of seizures (alcohol withdrawal, drugs lowering seizure threshold, suspected/known hyponatremia)
Cardiac arrhythmias: Rare reports of serious arrhythmias associated with ionic osmotic laxative products
Osmotic laxative products may produce colonic mucosal aphthous ulcerations; reports of serious cases of ischemic colitis requiring hospitalization; coadministration with stimulant laxatives may increase risk
If GI obstruction or perforation suspected, perform appropriate diagnostic studies to rule out these conditions before administering; caution with severe active ulcerative colitis
Patients with impaired gag reflex or other swallowing abnormalities are at risk for regurgitation or aspiration of bowel prep solution
Fluid and serum chemistry abnormalities
- Advise patients to hydrate adequately before, during, and after use
- Correct fluid and electrolyte abnormalities before treatment to avoid serious adverse effects (eg, arrhythmias, seizures, renal impairment)
- Caution in patients with conditions or medications that increase risk for fluid and electrolyte disturbances or may increase the risk of adverse events of seizure, arrhythmias, and renal impairment
- If significant vomiting or signs of dehydration develops consider performing post-colonoscopy laboratory tests (eg, electrolytes, creatinine, BUN)
- Can cause temporary elevations in uric acid; monitor patients with gout for acute flare
Drug interaction overview
- Oral medication administered within 1 hr before bowel prep may not be absorbed properly
- Caution if coadministration with drugs that increase risk of fluid and electrolyte disturbances or may increase risk of seizure, arrhythmias, or prolonged QT
- Avoid coadministration with stimulant laxatives owing to increased risk of mucosal ulceration or ischemic colitis
- Caution if coadministered with medications that may affect renal function (eg, diuretics, ACE inhibitors, ARBs, NSAIDs)
-
Chelation with magnesium
- Take tetracycline or fluoroquinolone antibiotics, iron, digoxin, chlorpromazine, or penicillamine at least 2 hr before and not less than 6 hr after administration of bowel prep to avoid chelation
Pregnancy & Lactation
Pregnancy
Data are unavailable data on use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes
Animal reproductive studies have not been conducted
Lactation
There are no data available on presence of drug combination in human or animal milk, effects on breastfed child, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for prep kit and any potential adverse effects on breastfed child from product or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Osmotic laxative; sulfate salts provide sulfate anions and associated cations causing water retention within bowel; osmotic effect of unabsorbed ions and large volume of water ingested produces copious watery diarrhea
Pharmacokinetics
Half-Life: 8.5 hr
Peak Plasma Time (serum sulfate): 17 hr (1st dose); 5 hr (2nd dose); renal impairment increases Tmax by 44% and AUC by 54%
Excretion (sulfate): predominantly in feces
Administration
Oral Preparation
Correct fluid and electrolyte abnormalities before treatment
Dilute bowel prep kit in water before ingestion
Consume additional water after each dose of bowel prep
On day before colonoscopy, consume only a light breakfast or clear liquids (eg, water, strained fruit juice without pulp, lemonade, plain coffee or tea, chicken broth, gelatin dessert without fruit)
On day of colonoscopy only consume clear liquids up to 2 hours before colonoscopy Do not eat solid food, drink milk, or eat or drink anything colored red or purple
Do not drink alcohol
Do not take other laxatives while taking bowel prep
Do not take oral medications within 1 hr of starting each dose of bowel prep
Stop consumption of all fluids at least 2 hr before colonoscopy
