# Liquid Paraffin (Mineral Oil) ## Overview Liquid paraffin is a highly refined mineral oil used as a lubricant laxative. It works by coating the bowel contents, preventing water absorption, and softening the stool to facilitate easy passage. ## Primary Indications * Short-term management of occasional constipation. * Fecal impaction (often used as an adjunct). ## Adult Dosing * **Oral:** 15–45 mL daily, usually administered at bedtime. * **Dosing varies by local protocol:** Some clinicians prefer divided doses or titration based on bowel response. Do not exceed 45 mL/day unless directed by a physician. ## Pediatric Dosing * **Children 6–12 years:** 5–20 mL daily. * **Safety Note:** Generally discouraged in children under 6 years old due to the risk of aspiration. Always consult local pediatric protocols as dosing is highly weight-dependent and age-sensitive. ## Dose Adjustments * **Hepatic/Renal:** No specific adjustments required, but caution is advised in elderly or debilitated patients due to aspiration risks. ## Contraindications * Hypersensitivity to the drug. * Patients with dysphagia or risk of aspiration (e.g., elderly, neurological impairment). * Abdominal pain, nausea, vomiting, or signs of appendicitis/obstruction. * Prolonged use (increases risk of lipid pneumonia or malabsorption). * Presence of anal fissures or hemorrhoidal issues where local irritation may occur. ## Adverse Effects * **Respiratory:** Lipoid pneumonia (secondary to micro-aspiration). * **Gastrointestinal:** Anal seepage, pruritus ani, and staining of undergarments. * **Nutritional:** Malabsorption of fat-soluble vitamins (A, D, E, K) with long-term use. ## Key Drug Interactions * **Fat-soluble vitamins:** Liquid paraffin may impair the absorption of vitamins A, D, E, and K. Administer at least 2 hours apart. * **Oral contraceptives/other drugs:** May reduce the absorption of certain concomitant oral medications due to increased intestinal transit time. * **Docusate:** Concurrent use is strictly avoided as liquid paraffin increases the absorption of docusate, potentially leading to systemic toxicity. ## Monitoring * Frequency and consistency of bowel movements. * Signs of respiratory distress (cough, dyspnea) suggesting aspiration. * Baseline and periodic monitoring of fat-soluble vitamin levels if chronic use is erroneously considered. ## Clinical Pearls * **Aspiration Risk:** Advise patients to never take the dose immediately before lying down to mitigate the significant risk of lipoid pneumonia. * **Duration:** Use should be strictly limited to the shortest duration possible (typically <1 week). * **Stool Leakage:** Counsel patients that anal leakage is a common side effect of excessive dosing. * **Not a first-line agent:** Due to the risk of aspiration and vitamin malabsorption, osmotic laxatives (e.g., polyethylene glycol) are generally preferred for chronic constipation. *** *Disclaimer: This information is for educational purposes only.
