Movicol Junior Plain (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

• Movicol Junior Plain, an osmotic laxative, is used to manage constipation in the pediatric population.
• Constipation in children: softens stool and facilitates easier passage, helping to establish regular bowel movements.
• Functional constipation: provides osmotic effect to relieve stool hardness and reduce abdominal discomfort.
• Chronic constipation: assists in long‑term bowel regulation when dietary measures are insufficient.

• Macrogol 3350 creates an osmotic gradient within the intestinal lumen by retaining water molecules. The retained water increases stool water content, softening the fecal mass and expanding its volume, which stimulates peristalsis and promotes bowel evacuation. The accompanying electrolytes (sodium hydrogen carbonate, potassium chloride, sodium chloride) help maintain electrolyte balance during the osmotic process.

Movicol Junior Plain may be associated with the following adverse reactions.

Common Side Effects

• Abdominal bloating: mild distension of the abdomen.
• Nausea: feeling of sickness or urge to vomit.
• Flatulence: increased intestinal gas.
• Diarrhoea: loose, watery stools.

Serious or Rare Side Effects

• Electrolyte imbalance: abnormal levels of sodium, potassium or chloride.
• Severe abdominal pain: persistent or worsening pain requiring medical attention.

When prescribing Movicol Junior Plain, consider the following precautions.

• Renal impairment: monitor kidney function as electrolyte handling may be affected.
• Dehydration risk: ensure adequate fluid intake to avoid excessive fluid loss.
• Electrolyte disorders: assess baseline sodium and potassium levels before use.
• Gastrointestinal obstruction: avoid use if a mechanical blockage is present.
• Hypersensitivity: discontinue if allergic reaction such as rash or swelling occurs.
• Store at ambient temperature: keep in the original container, protect from moisture and heat.

Movicol Junior Plain can interact with certain medicines; awareness of these interactions helps ensure safe use.

Major Interactions (Avoid)

• Anticholinergic agents: may reduce laxative effectiveness.
• Loop diuretics: increased risk of electrolyte disturbances.
• Lithium: altered lithium levels due to changes in sodium balance.

Moderate Interactions (Monitor Closely)

• Oral rehydration salts: may affect electrolyte balance.
• Other osmotic laxatives: additive effect leading to diarrhoea.
• Antibiotics such as tetracycline: possible reduced absorption due to altered gut transit.
