# Liquid Paraffin ## Overview Liquid paraffin is a highly refined mineral oil used as an emollient and lubricant. It works by softening stool and lubricating the intestinal tract, making defecation easier. ## Primary Indications Constipation. ## Adult Dosing * **Oral:** 10-30 mL once daily, typically at bedtime. Dosing can be adjusted based on patient response. Maximum dose typically not specified but should be used cautiously to avoid complications. ## Pediatric Dosing * **Oral:** * 1-5 years: 2.5-5 mL once daily. * 6-12 years: 5-10 mL once daily. * Over 12 years: Use adult dosing. * Dosing can be adjusted based on patient response. ## Dose Adjustments No dose adjustments are typically required for renal or hepatic impairment. ## Contraindications * Hypersensitivity to liquid paraffin. * Acute abdominal conditions (e.g., appendicitis, intestinal obstruction, undiagnosed abdominal pain). * Difficulty swallowing. * Concurrent use with certain medications where absorption could be significantly impaired (see Key Drug Interactions). ## Adverse Effects * Gastrointestinal: Abdominal cramping, nausea, vomiting, diarrhea, anal leakage. * Respiratory: Lipid pneumonia (if aspirated, particularly in the elderly or those with impaired swallowing). * Other: Pruritus, rash. Long-term use may lead to vitamin malabsorption (vitamins A, D, E, K). ## Key Drug Interactions * **Decreased absorption of fat-soluble vitamins (A, D, E, K):** Due to its lipophilic nature, liquid paraffin can reduce the absorption of these vitamins. * **Decreased absorption of other oral medications:** Particularly those that are lipophilic or require an intact gastrointestinal tract for absorption (e.g., warfarin, digoxin, some oral contraceptives). Separation of administration by at least 2 hours is recommended. ## Monitoring * Monitor for effectiveness in relieving constipation. * Assess for signs of abdominal pain, cramping, or anal leakage. * Consider monitoring for signs of vitamin deficiency with prolonged, regular use, especially in vulnerable populations. * Assess swallowing ability, particularly in the elderly or debilitated. ## Clinical Pearls * Administer at bedtime to minimize anal leakage during the day. * Due to the risk of aspiration and subsequent lipid pneumonia, caution is advised in the elderly, those with dysphagia, or in infants. * Prolonged or frequent use is generally discouraged due to potential for dependence and nutrient malabsorption. * It is not absorbed systemically and is considered relatively safe for short-term use. *** **Disclaimer:** This information is intended for clinical use and is not a substitute for professional medical advice.
