Moviprep (Ascorbic Acid, Sodium Ascorbate, Potassium Chloride, Sodium Chloride, Sodium Sulfate Anhydrous, Macr)

Moviprep, an osmotic laxative used for bowel preparation, is indicated for the following clinical situations:

• Colonoscopy: effective bowel cleansing to enable clear visualization during colonoscopic examination.
• Flexible sigmoidoscopy: bowel preparation to improve mucosal assessment in sigmoidoscopic procedures.
• Therapeutic gastrointestinal procedures: bowel evacuation prior to interventions such as polypectomy or endoscopic mucosal resection.
• Radiologic imaging of the colon: preparation to reduce fecal material for CT colonography.

• Moviprep contains polyethylene glycol electrolyte solution that remains largely unabsorbed in the gastrointestinal tract. By creating an osmotic gradient, it retains water within the intestinal lumen, increasing stool volume and softening feces, which promotes rapid bowel evacuation. The accompanying electrolytes help maintain fluid balance while facilitating the cleansing process.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Abdominal discomfort: cramping or pain during bowel evacuation.
• Bloating: sensation of fullness due to retained gas.
• Vomiting: occasional expulsion of stomach contents.
• Headache: transient mild headache.
• Mild electrolyte imbalance: slight changes in sodium or potassium levels.

Serious or Rare Side Effects

• Severe dehydration: marked loss of body fluids.
• Significant electrolyte disturbances: hypernatremia or hypokalemia.
• Renal impairment: reduced kidney function in susceptible patients.
• Allergic reaction: rash, itching, or swelling.
• Severe abdominal pain: persistent intense pain.
• Colonic perforation: rare but life‑threatening tear of the colon wall.

Before using Moviprep, consider the following precautions:

• Renal function assessment: evaluate kidney health, especially in patients with chronic kidney disease.
• Electrolyte monitoring: check baseline sodium, potassium, and magnesium levels.
• Contraindication in bowel obstruction: avoid use when mechanical blockage is present.
• Caution in inflammatory bowel disease: may exacerbate symptoms.
• Adequate fluid intake: ensure sufficient oral fluids to prevent dehydration.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Moviprep may interact with other medicines as follows:

Major Interactions (Avoid)

• Lithium: risk of increased lithium toxicity due to altered renal clearance.
• Diuretics: potential for severe electrolyte disturbances.
• ACE inhibitors or ARBs: heightened risk of renal dysfunction.

Moderate Interactions (Monitor Closely)

• Oral antibiotics: may affect gut flora and alter bowel preparation effectiveness.
• Antacids: can influence electrolyte balance.
• NSAIDs: combined use may increase risk of renal impairment.
