Movicol Ease Citrus Flavour (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Movicol Ease Citrus Flavour (macrogol 3350 with electrolytes) is an osmotic laxative used to manage conditions involving reduced bowel motility.

• Constipation: softens stools and promotes regular bowel movements in patients with occasional or chronic constipation.
• Opioid‑induced constipation: alleviates bowel dysfunction caused by opioid therapy by increasing intestinal water content.
• Functional bowel disorders: improves stool frequency and consistency in functional constipation associated with irritable bowel syndrome.

• Macrogol 3350 is a high‑molecular‑weight polymer that is poorly absorbed from the gastrointestinal tract. It retains water in the intestinal lumen by osmosis, creating a hyper‑osmolar environment that draws fluid into the bowel. The resulting increase in stool water content softens the feces and expands the intestinal volume, stimulating peristalsis and facilitating the passage of stool. The accompanying electrolytes (sodium hydrogen carbonate, potassium chloride, sodium chloride) help maintain electrolyte balance during the osmotic process.

Common and serious adverse reactions have been reported with macrogol‑based laxatives.

Common Side Effects

• Abdominal bloating: sensation of fullness or swelling in the abdomen.
• Flatulence: increased intestinal gas causing discomfort.
• Diarrhoea: loose, watery stools occurring with higher doses.
• Nausea: mild feeling of sickness or urge to vomit.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal sodium or potassium levels requiring medical attention.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Dehydration: excessive fluid loss leading to dizziness or low blood pressure.

Before using Movicol Ease Citrus Flavour, consider the following safety measures.

• Assess renal function: evaluate kidney status before initiating therapy, especially in patients with renal impairment.
• Monitor fluid balance: ensure adequate hydration to prevent dehydration during treatment.
• Adjust dose in the elderly: start with a lower dose and titrate cautiously in older adults.
• Review concomitant medications: consider potential interactions with drugs affecting electrolyte balance.
• Store at room temperature: keep below 25°C in the original container, protect from moisture and direct sunlight.

Potential drug interactions should be reviewed prior to prescribing Movicol Ease Citrus Flavour.

Major Interactions (Avoid)

• Concomitant use with other osmotic laxatives: may cause excessive fluid loss and severe electrolyte disturbances.
• High-dose mineral supplements (e.g., potassium chloride): can lead to dangerous electrolyte imbalances when combined.

Moderate Interactions (Monitor Closely)

• Diuretics: may increase risk of dehydration and electrolyte shifts; monitor patient status.
• Antacids containing sodium or potassium: may alter electrolyte composition; observe levels.
• Antidepressants affecting gastrointestinal motility (e.g., tricyclics): may modify laxative effect; adjust therapy as needed.
