Liquid%2520paraffin

# Liquid paraffin ## Overview Liquid paraffin is a mineral oil laxative that acts by lubricating and softening the stool. It is generally considered a second-line agent due to safety concerns. Use has declined in favor of safer alternatives. ## Primary Indications - Short-term relief of constipation (e.g., post-surgery, opioid-induced, or in patients where straining should be avoided). - Fecal impaction (as an adjunct to enemas or oral stimulants). ## Adult Dosing - **Oral:** 15–45 mL (1–3 tablespoons) once daily at bedtime. - Maximum single dose: 45 mL. Treatment duration should not exceed 1–2 weeks without medical assessment. - *Note:* Dosing may vary by local protocol; confirm product-specific concentration. ## Pediatric Dosing - **Children 6–12 years:** 5–15 mL once daily at bedtime. - **Children <6 years:** Not recommended due to aspiration risk and lack of evidence. - In all pediatric cases, use only under specialist guidance and for short periods. ## Dose Adjustments - **Renal/hepatic impairment:** No specific dose adjustment required, but caution with prolonged use due to potential for accumulation of paraffin. - **Elderly:** Use lowest effective dose and monitor for aspiration and leakage. ## Contraindications - Intestinal obstruction, ileus, or acute abdominal pain of unknown cause. - Dysphagia or swallowing difficulties (risk of aspiration pneumonitis). - Known hypersensitivity to mineral oils. - Concurrent use of docusate (increased risk of hepatotoxicity – theoretical, but many sources advise avoidance). ## Adverse Effects - Aspiration pneumonitis (if accidentally inhaled). - Anal leakage or seepage (common with >30 mL/day or prolonged use). - Decreased absorption of fat-soluble vitamins (A, D, E, K) with chronic use. - Anal foreign body/granuloma (rare, with long-term use). - Lipoid pneumonia (from aspiration). ## Key Drug Interactions - **Oral anticoagulants (e.g., warfarin):** Reduced absorption of vitamin K may potentiate anticoagulant effect; monitor INR closely. - **Oral contraceptive pills / hormone therapy:** Theoretical reduction in absorption; consider temporary separation (2 hours) or alternative laxative. - **Docusate:** Avoid concurrent use (possible hepatotoxicity). - **Vitamin supplements (A, D, E, K):** Space administration by at least 2 hours. ## Monitoring - Assess for swallowing ability before dispensing (especially in elderly, stroke, or Parkinson’s patients). - Observe for anal leakage, abdominal pain, or lipid-laden macrophages in sputum if cough develops. - For prolonged use (>2 weeks): check vitamin A, D, E, and K levels if clinical deficiency suspected. ## Clinical Pearls - **Give on an empty stomach (1 hour before or 2 hours after meals)** to reduce interference with meal-based nutrients. - **Never administer at bedtime in patients with GERD, sedation, or poor gag reflex** – aspiration risk peaks when supine. - **Flavoring** (e.g., chilled, mixed with orange juice) can improve palatability. - **Avoid chronic use** – alternatives (polyethylene glycol, lactulose, senna) are safer for long-term management. - **Do not use as first-line laxative** in most adults or children. --- **Educational Disclaimer:** This information is for educational purposes and does not replace independent clinical judgment.
