Movicol

# movicol ## Overview - **Classification**: Osmotic laxative (Macrogol 3350 with electrolytes). - **Mechanism**: Polyethylene Glycol (PEG) acts as an osmotic agent, retaining water in the bowel. This softens stool, increases faecal bulk, and stimulates bowel motility. Electrolytes prevent significant fluid and electrolyte shifts. ## Primary Indications 1. **Chronic Constipation**: Symptomatic treatment of chronic constipation. 2. **Faecal Impaction**: Resolution of faecal impaction, defined as refractory constipation with faecal loading of the rectum and/or colon. ## Adult Dosing ### Standard Dosing **Chronic Constipation** - **Dose**: **1 sachet** (13.8g Movicol powder) - **Frequency**: **1-3 times daily** - **Route**: Oral, dissolved in **125 mL** (approx. half a glass) of water. - **Duration**: Typically short-term, up to 2 weeks initially.
