# Liquid Paraffin ## Overview Liquid paraffin is a mineral oil that acts as a lubricant laxative. It is poorly absorbed and works by softening and lubricating the fecal mass, making it easier to pass. It is typically used for short-term relief of occasional constipation. ## Primary Indications * Occasional constipation ## Adult Dosing * 10-30 mL once daily, typically at bedtime. May be taken as a single dose or divided doses. * Maximum dose: Not clearly established, but generally avoid chronic high-dose use. ## Pediatric Dosing Dosing in children should be guided by local protocols or a pediatrician due to variability in age, weight, and clinical response. Generally, lower doses are recommended for younger children. * **< 1 year:** Use with extreme caution and only under medical supervision. Doses typically range from 1-5 mL once daily. * **1-5 years:** 5-10 mL once daily. * **6-12 years:** 10-15 mL once daily. * **> 12 years:** As per adult dosing. ## Dose Adjustments No specific dose adjustments are typically required for renal or hepatic impairment, as systemic absorption is minimal. ## Contraindications * Abdominal pain of unknown origin. * Nausea or vomiting. * Intestinal obstruction. * Difficulty swallowing (risk of aspiration, especially in the elderly or debilitated). * Hypersensitivity to liquid paraffin. ## Adverse Effects * Anal leakage, staining, and irritation. * Abdominal cramping and discomfort. * Nausea. * Diarrhea (with excessive doses). * Lipoid pneumonia (rare, with chronic aspiration). * Decreased absorption of fat-soluble vitamins (A, D, E, K) with chronic, high-dose use. ## Key Drug Interactions * **Mineral Oil:** Concurrent use with other mineral oil-containing products may increase the risk of adverse effects. * **Fat-soluble vitamin supplements:** May reduce absorption. Separate administration by at least 2 hours. * **Anticoagulants (e.g., warfarin):** Mineral oil may potentially decrease absorption and efficacy, though clinical significance is debated. Monitor INR closely if concomitant use is necessary. ## Monitoring * Bowel movements and symptoms of constipation. * Signs of anal leakage or irritation. * For chronic use: Monitor for signs of vitamin deficiency or lipoid pneumonia. ## Clinical Pearls * Administer at bedtime to minimize daytime leakage and interference with meals. * Educate patients about potential anal leakage and advise using a pad. * Avoid concurrent use with other mineral oil preparations. * Long-term use may lead to dependence, vitamin malabsorption, and impaction. It is generally recommended for short-term, occasional use only. * Caution is advised in the elderly and debilitated due to the risk of aspiration and lipoid pneumonia. *** *Disclaimer: This information is intended for healthcare professionals.
