6.1 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. Adults The safety of sodium sulfate, potassium sulfate and magnesium sulfate oral solution was evaluated in a multi-center, randomized, active controlled trial in 379 adult patients undergoing colonoscopy. Most Common Adverse Reactions Table 1 shows the most common adverse reactions reported in at least 2% of patients receiving sodium sulfate, potassium sulfate and magnesium sulfate oral solution or the control (a bowel prep containing polyethylene glycol and electrolytes (PEG + E)) administered in split-dose (2-day) regimens.

Less Common Adverse Reactions AV Block (1 case) and CK increase. Adverse Reactions with Unapproved Use In another study of 408 adult patients, higher rates of the following adverse reactions and laboratory abnormalities were reported in patients treated with sodium sulfate, potassium sulfate and magnesium sulfate oral solution as an evening-only (1-day) regimen compared to the split-dose (2-day) regimen. overall discomfort, abdominal distention, nausea, and vomiting total bilirubin (high), BUN (high), creatinine (high), osmolality (high), potassium (high) and uric acid (high) Administration of sodium sulfate, potassium sulfate and magnesium sulfate oral solution in an evening-only (1-day) dosing regimen is not recommended. Pediatric use information is approved for Braintree Laboratories, Inc.’s SUPREP BOWEL PREP KIT (sodium sulfate, potassium sulfate, and magnesium sulfate) oral solution. However, due to Braintree Laboratories, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

6.2 Postmarketing

Experience The following adverse reactions have been identified during post-approval use of sodium sulfate, potassium sulfate and magnesium sulfate oral solution. 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.

Hypersensitivity: anaphylaxis, angioedema, dyspnea, rash, pruritus, urticaria
