Sodium Phosphate Enema

Sodium Phosphate Enema contains Sodium dihydrogen phosphate + Disodium hydrogen phosphate (as sodium phosphate enema; strength varies by pack/label). Prescription required.

Relief of constipation, bowel cleansing/evacuation before rectal/intestinal examinations or procedures

Sodium phosphate is a hyperosmotic laxative. It draws water into the colon, softening stool and increasing bowel distension, which stimulates peristalsis and leads to bowel evacuation.

Rectal use only. Use as directed on the label/by doctor; usually a single dose enema. Lie on your side, insert nozzle gently, squeeze bottle, and retain for a few minutes if possible until urge to pass stool. Do not use more than once in 24 hours unless advised; drink adequate fluids.

Abdominal cramps, rectal irritation/burning, nausea, bloating, diarrhea, dizziness

Do not use in children unless prescribed. Avoid or use only under medical supervision in kidney disease, heart failure, dehydration, bowel obstruction, severe abdominal pain/unknown cause, inflammatory bowel disease flare, or if unable to pass gas/stool. Overuse can cause serious electrolyte disturbances (high phosphate, low calcium, low potassium), dehydration, kidney injury and arrhythmias; seek urgent care if severe weakness, fainting, no bowel movement after use, rectal bleeding, or severe abdominal pain occurs.

Diuretics, ACE inhibitors/ARBs, NSAIDs (increase risk of kidney injury/dehydration), other laxatives, medicines affecting electrolytes (e.g., digoxin risk increases with electrolyte imbalance), calcium/aluminium/magnesium supplements or binders (may affect phosphate/calcium balance)

Store below 25°C in a cool, dry place; protect from excessive heat and light. Keep out of reach of children. Do not use if seal is broken or solution is discoloured.
