Advise all patients to hydrate adequately before, during, and after the use of SUTAB.

If a patient develops significant vomiting or signs of dehydration after taking SUTAB, consider performing postcolonoscopy lab tests (electrolytes, creatinine, and BUN). Fluid and electrolyte disturbances can lead to serious adverse events including cardiac arrhythmias, seizures, and renal impairment. Correct fluid and electrolyte abnormalities before treatment with SUTAB. Use SUTAB with caution in 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.


SUTAB® (sodium sulfate, magnesium sulfate, potassium chloride) tablets for oral use is an osmotic laxative indicated for cleansing of the colon in preparation for colonoscopy in adults.

Use is contraindicated in the following conditions: gastrointestinal obstruction or ileus, bowel perforation, toxic colitis or toxic megacolon, gastric retention, hypersensitivity to any ingredient in SUTAB.

A low residue breakfast may be consumed. After breakfast, only clear liquids may be consumed until after the colonoscopy. Administration of two doses of SUTAB (24 tablets) are required for a complete preparation for colonoscopy. Twelve (12) tablets are equivalent to one dose. Each SUTAB bottle contains a desiccant. Remove and discard the desiccant from both bottles the evening prior to the colonoscopy. Water must be consumed with each dose of SUTAB and additional water must be consumed after each dose. Complete all SUTAB tablets and required water at least 2 hours before colonoscopy.

Risk of fluid and electrolyte abnormalities: Encourage adequate hydration, assess concurrent medications and consider laboratory assessments prior to and after each use; Cardiac arrhythmias: Consider pre-dose and post-colonoscopy ECGs in patients at increased risk; Seizures: Use caution in patients with a history of seizures and patients at increased risk of seizures, including medications that lower the seizure threshold; Patients with renal impairment or taking concomitant medications that affect renal function: Use caution, ensure adequate hydration and consider laboratory testing; Colonic mucosal ulcerations: Consider potential for mucosal ulcerations when interpreting colonoscopy findings in patients with known or suspected inflammatory bowel disease. Suspected GI obstruction or perforation: Rule out the diagnosis before administration. Hypersensitivity reactions, including anaphylaxis: Inform patients to seek immediate medical care if symptoms occur. Risk of Gastrointestinal Complications with Ingestion of Desiccant: Postmarketing reports of ingestion of the desiccant along with SUTAB tablets has been reported and may be associated with risk of gastrointestinal complications and/or choking.

Most common gastrointestinal adverse reactions are: nausea, abdominal distension, vomiting, and upper abdominal pain.
