Dosing overview

The recommended dosing regimen begins with taking three lax-tab tablets with one full glass of water at 12:00 PM. The magnesium citrate sachet solution should be ingested slowly but completely at 6:00 PM and followed by drinking adequate glasses of water or recommended clear fluids, at least one glass every hour after that. The dosing regimen may be adjusted by a healthcare professional as required.

Key safety warnings

GO-KIT is likely to cause transient hypovolaemia, hence adequate fluid intake or replacement should be ensured. Use with caution in patients with inflammatory bowel disease, marked bloody diarrhoea, pre-existing electrolyte disturbances, congestive heart failure, diabetes and those with a stoma. GO-KIT should be administered with caution in patients with congestive heart failure and pre-existing electrolyte disturbances, and these patients should be monitored. GO-KIT should be administered with caution to patients using calcium channel blockers, diuretics or other medications that may affect electrolyte serum levels and exacerbate volume depletion, and these patients should be monitored. Patients with kidney disease or impaired renal function should be monitored. Caution should be exercised in the elderly as dehydration and electrolyte depletion may occur, and elderly patients must receive adequate fluids during administration. Nausea, vomiting and anal irritation are the most common reactions and are usually transient and subside rapidly. Bisacodyl may cause abdominal discomfort such as colic or cramps. Prolonged use of GO-KIT may result in dehydration and electrolyte disturbances. Hypersensitivity reactions including angioedema and anaphylactoid reactions have been reported rarely.

Contraindications

GO-KIT should not be used by patients with acute abdominal conditions such as appendicitis, gastrointestinal obstruction, gastric retention, bowel perforation (frank or suspected), toxic megacolon, toxic colitis, ileus, body weight less than 20 kg, severe dehydration, or hypersensitivity to any of the ingredients.
