Ezivac Enema

# Ezivac enema ## Overview - **Classification**: Saline laxative (Osmotic laxative) - **Mechanism**: Draws water into the colon via osmosis, softening stool and promoting bowel evacuation by increasing intraluminal pressure. ## Primary Indications 1. **Constipation relief**: Short-term treatment of occasional constipation. 2. **Bowel preparation**: Cleansing the bowel prior to surgery, colonoscopy, or radiological examination. ## Adult Dosing ### Standard Dosing **Constipation Relief / Bowel Preparation** - **Dose**: **120 mL** (contains sodium phosphate, typically 2.4g dibasic / 10.8g monobasic) - **Frequency**: Single dose, PRN for constipation or as directed for bowel prep. - **Route**: Rectal enema - **Duration**: Single application; not for chronic use. ### Dose Adjustments - **Renal Impairment**: **Contraindicated** in moderate to severe renal impairment (CrCl < 30 mL/min) due to hyperphosphatemia risk. Use extreme caution in mild impairment. - **Hepatic Impairment**: No specific dose adjustment, but use caution due to electrolyte disturbance risk. - **Elderly Patients**: Use with caution. Increased risk for electrolyte imbalances, dehydration, and renal impairment. ## Pediatric Dosing ### Neonates (0-28 days) - **Contraindicated**: High risk of severe electrolyte imbalances (hyperphosphatemia, hypocalcemia) and dehydration. ### Infants (1-12 months) - **Contraindicated**: High risk of severe electrolyte imbalances and dehydration. Glycerin suppositories are preferred alternatives. ### Children (1-12 years) - **Children < 2 years**: **Contraindicated**. - **Children 2-11 years (Bowel Preparation / Constipation Relief)**: - **Dose**: **60 mL** (half adult volume) - **Frequency**: Single dose - **Maximum**: **60 mL** in 24 hours. - **Special Notes**: Use only under strict medical supervision. Closely monitor for electrolyte disturbances. ### Adolescents (13-18 years) - **Constipation Relief / Bowel Preparation**: - **Dose**: **120 mL** (adult dose) - **Frequency**: Single dose - **Maximum**: **120 mL** in 24 hours. - **Special Notes**: Monitor for electrolyte imbalances, especially with underlying conditions. ## Safety Information ### Contraindications - **Absolute**: Hypersensitivity to sodium phosphate. - **Absolute**: Infants and children < 2 years. - **Absolute**: Intestinal obstruction, imperforate anus, congenital megacolon, paralytic ileus. - **Absolute**: Acute abdomen, appendicitis, inflammatory bowel disease. - **Absolute**: Moderate to severe renal impairment (CrCl < 30 mL/min). - **Absolute**: Congestive heart failure, severe cardiac disease. - **Absolute**: Significant electrolyte disturbances. ### Common Adverse Effects - **Very Common (>10%)**: Abdominal cramping, discomfort, flatulence. - **Common (1-10%)**: Nausea, vomiting, rectal irritation, tenesmus. - **Serious but Rare**: Hyperphosphatemia, hypocalcemia, hypernatremia, dehydration, metabolic acidosis. Cardiac arrhythmias (due to electrolyte imbalance), renal failure. ### Key Drug Interactions - **Diuretics (e.g., furosemide)**: Increased risk of dehydration and electrolyte imbalances. Monitor electrolytes. - **ACE Inhibitors/ARBs**: Increased risk of renal dysfunction and electrolyte disturbances. - **NSAIDs**: May increase risk of renal impairment, exacerbating electrolyte issues. - **Oral phosphate preparations**: Avoid concurrent use due to additive effects and increased risk of hyperphosphatemia. ## Monitoring & Follow-up - **Before Treatment**: Assess hydration status, renal function, and cardiac history, especially in high-risk patients. - **During Treatment**: Monitor for signs of dehydration, abdominal pain, or systemic adverse effects (dizziness, weakness, muscle cramps). - **Clinical Signs**: Watch for signs of electrolyte imbalance, especially in pediatric, elderly, or renally impaired patients. ## Clinical Pearls - 💡 **Tip 1**: Administer enema at room temperature to avoid abdominal cramping. - 💡 **Tip 2**: Advise patients to remain lying down for **5-10 minutes** after administration to aid retention. - 💡 **Tip 3**: Not for chronic constipation. Repeated use can lead to laxative dependence and severe electrolyte disturbances. - 💡 **Tip 4**: Ensure adequate fluid intake, especially during bowel preparation, to prevent dehydration. > **⚠️ Important**: This information is for educational purposes only.
