Movicol Neutral (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Movicol Neutral is an osmotic laxative used in the management of conditions affecting bowel motility and stool consistency.

• Constipation: softens stool and promotes regular bowel movements.
• Faecal impaction: helps to break down hardened stool and facilitate evacuation.
• Bowel preparation for diagnostic procedures: clears the intestinal tract to improve visualization during colonoscopy or imaging studies.

• Macrogol 3350 increases the osmotic pressure within the intestinal lumen, drawing water into the bowel. The added water softens the stool and expands its volume, stimulating peristalsis and facilitating the passage of feces without being absorbed systemically.

Movicol Neutral may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal bloating: feeling of fullness or distension in the abdomen.
• Flatulence: increased gas production leading to passing of wind.
• Nausea: mild sensation of unease in the stomach.
• Diarrhoea: loose, watery stools occurring more frequently than normal.

Serious or Rare Side Effects

• Severe dehydration: excessive loss of body fluids requiring medical attention.
• Electrolyte imbalance: abnormal levels of sodium, potassium or chloride that may affect heart rhythm.
• Allergic reaction: rash, itching, swelling or difficulty breathing indicating hypersensitivity.
• Severe abdominal pain: intense pain that may signal complications such as obstruction.
• Rectal bleeding: presence of blood in stool indicating possible mucosal injury.

Before initiating therapy with Movicol Neutral, consider the following safety measures.

• Renal function assessment: evaluate kidney performance to avoid fluid overload.
• Electrolyte monitoring: check serum sodium, potassium and chloride levels periodically.
• Bowel obstruction caution: avoid use in patients with known mechanical blockage.
• Elderly dose adjustment: start with the lowest effective dose in older adults.
• Hypersensitivity avoidance: discontinue if signs of allergic reaction appear.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Movicol Neutral can interact with other medicines, influencing efficacy or safety.

Major Interactions (Avoid)

• Concurrent osmotic laxatives: may cause excessive fluid loss and electrolyte disturbances.
• Loop diuretics: increased risk of dehydration and electrolyte imbalance.
• Lithium therapy: altered lithium plasma concentrations leading to toxicity.

Moderate Interactions (Monitor Closely)

• Anticholinergic agents: may reduce the laxative effect.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): potential for gastrointestinal irritation.
• ACE inhibitors or ARBs: monitor potassium levels due to combined electrolyte effects.
