# Liquid Paraffin
## Overview
Liquid paraffin is a mineral oil used as an emollient, laxative, and lubricant. It works by softening stool and lubricating the intestinal tract, facilitating easier passage.
## Primary Indications
* Constipation
* Skin conditions requiring emollient properties (e.g., dry skin, eczema)
## Adult Dosing
### Laxative
* **Oral:** 10-30 mL once daily, typically at bedtime. Dosing may be adjusted based on response. Some sources suggest up to 45 mL daily for short-term use.
### Emollient
* **Topical:** Apply thinly to affected skin areas as needed.
## Pediatric Dosing
Dosing in children should be carefully considered due to the risk of aspiration and impaired absorption of fat-soluble vitamins. Consult a pediatrician or local protocol for specific guidance.
* **Oral (Laxative):** Generally not recommended for infants. For children over 1 year, very low doses may be considered under medical supervision, often starting at 5 mL once daily. Precise dosing depends heavily on age and weight and should be individualized.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, as systemic absorption is minimal.
## Contraindications
* Hypersensitivity to liquid paraffin.
* Patients with difficulty swallowing, due to the risk of aspiration and lipoid pneumonia.
* Appendicitis or undiagnosed abdominal pain.
* Intestinal obstruction.
* Prolonged use in children, especially infants, due to potential interference with vitamin absorption and risk of anal leakage.
## Adverse Effects
* **Gastrointestinal:** Abdominal cramping, diarrhea, anal leakage, nausea, vomiting.
* **Respiratory:** Lipoid pneumonia (if aspirated).
* **Other:** Decreased absorption of fat-soluble vitamins (A, D, E, K) with chronic or high-dose use.
## Key Drug Interactions
* **Fat-soluble vitamins:** Long-term or high-dose use may reduce the absorption of vitamins A, D, E, and K. Consider vitamin supplementation if clinically indicated.
* **Docusate:** Concurrent use is generally not recommended as it may increase liquid paraffin absorption.
* **Other laxatives:** May potentiate effects or cause electrolyte imbalance.
## Monitoring
* Bowel movements (frequency, consistency).
* Signs of anal leakage or leakage with stool.
* Nutritional status, particularly vitamin levels, with chronic use.
* Respiratory status, especially in patients with dysphagia or those receiving high doses.
## Clinical Pearls
* Administer at bedtime to minimize daytime inconvenience from anal leakage.
* Advise patients to remain upright for at least 30 minutes after taking oral liquid paraffin to reduce aspiration risk.
* Long-term use should be discouraged due to potential for dependence and vitamin malabsorption.
* Not suitable for pregnant or breastfeeding individuals without medical advice.
