Macrogol Al (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Macrogol Al is employed in conditions where increased intestinal water content is required to facilitate bowel movements or cleansing.

• Constipation: softens stool and promotes regular bowel movements.
• Bowel preparation for colonoscopy: clears the intestinal tract to improve visualisation during the procedure.
• Irritable bowel syndrome with constipation: helps alleviate abdominal discomfort by normalising stool consistency.

• Macrogol 3350 acts as an osmotic agent that retains water in the intestinal lumen by forming hydrogen bonds with water molecules. This increased fluid volume softens fecal mass, expands the stool, and stimulates peristalsis, facilitating easier passage. The accompanying electrolytes (sodium hydrogen carbonate, potassium chloride, sodium chloride) help maintain electrolyte balance during the laxative effect.

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

Common Side Effects

• Abdominal bloating: sensation of fullness in the abdomen.
• Flatulence: increased intestinal gas.
• Nausea: feeling of queasiness.
• Diarrhoea: loose, watery stools.
• Abdominal cramps: intermittent pain in the stomach area.
• Headache: mild to moderate head discomfort.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal levels of sodium, potassium, or chloride.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe dehydration: excessive loss of body fluids.
• Rectal bleeding: presence of blood in stool.
• Anaphylaxis: life‑threatening systemic allergic response.
• Severe abdominal pain: intense, persistent pain requiring medical attention.

When considering Macrogol Al, healthcare professionals should evaluate patient‑specific factors and follow safe handling practices.

• Renal function assessment: ensure adequate kidney function before use.
• Electrolyte monitoring: check serum electrolytes during prolonged therapy.
• Bowel obstruction caution: avoid in patients with known mechanical obstruction.
• Hypersensitivity avoidance: discontinue if allergic signs appear.
• Dose adjustment in elderly: consider lower initial dose due to slower gastrointestinal transit.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Macrogol Al 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 dehydration and electrolyte imbalance.
• Anticholinergic agents: may reduce gastrointestinal motility, counteracting laxative effect.

Moderate Interactions (Monitor Closely)

• Mineral supplements (e.g., calcium, magnesium): may alter absorption of electrolytes.
• NSAIDs: potential for increased gastrointestinal irritation.
• Oral antibiotics: possible alteration of gut flora affecting bowel habits.
