Macrogol + Electrolytes Eg (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Macrogol + Electrolytes Eg is an osmotic laxative used in conditions affecting bowel function.

• Chronic constipation: softens stool and promotes regular bowel movements.
• Acute constipation: provides rapid relief of bowel blockage.
• Bowel preparation for colonoscopy or imaging: cleanses the intestinal tract before procedures.
• Faecal impaction: helps to evacuate hardened stool in the lower colon.

• Macrogol 3350 is a high‑molecular‑weight polyethylene glycol that is poorly absorbed and retains water within the intestinal lumen by osmosis, increasing stool volume and softness. The accompanying electrolytes (sodium, potassium, chloride, bicarbonate) maintain electrolyte balance and prevent shifts that could occur with large fluid movements, supporting safe and effective bowel cleansing.

Macrogol + Electrolytes Eg may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Abdominal bloating: feeling of fullness or distension.
• Flatulence: increased intestinal gas.
• Diarrhea: loose stools if excess fluid is retained.
• Headache: occasional mild headache.
• Thirst: increased sensation of dryness.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal sodium or potassium levels.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe dehydration: excessive fluid loss leading to low blood pressure.
• Renal impairment: worsening kidney function in susceptible individuals.
• Acute abdominal pain: persistent or severe pain requiring medical attention.
• Hypersensitivity colitis: rare inflammatory response of the colon.

When prescribing Macrogol + Electrolytes Eg, clinicians should consider several safety measures.

• Assess renal function: ensure adequate kidney clearance before use.
• Monitor electrolyte status: check serum sodium and potassium during prolonged therapy.
• Use caution in bowel obstruction: avoid if mechanical blockage is suspected.
• Avoid in known hypersensitivity: discontinue if allergic signs appear.
• Adjust dose in elderly: start with lower amounts to reduce risk of dehydration.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Macrogol + Electrolytes Eg can interact with other medications that affect fluid or electrolyte balance.

Major Interactions (Avoid)

• Concurrent osmotic laxatives: may cause excessive fluid loss and electrolyte disturbances.
• Loop diuretics: increase risk of hyponatremia or hypokalemia.
• Certain anticholinergics: may reduce the laxative effect.

Moderate Interactions (Monitor Closely)

• NSAIDs: combined use may affect renal function.
• Mineral supplements (e.g., potassium chloride): may alter electrolyte levels.
• Antacids: could affect the absorption of concomitant oral medications.
