# Liquid Paraffin
## Overview
Liquid paraffin, also known as mineral oil, is a highly refined petroleum distillate. It acts as an emollient and a lubricant.
## Primary Indications
* Constipation (as a laxative)
* Prevention of fecal impaction
## Adult Dosing
* **Constipation:** 15-45 mL orally once daily, typically at bedtime. Dosing may be adjusted based on response.
* **Fecal Impaction:** May be used in combination with other agents per institutional protocol.
## Pediatric Dosing
Dosing for children is highly variable and should be guided by age, weight, and clinical judgment. Consult pediatric-specific guidelines or a specialist. A common starting point for younger children might be 5 mL, increasing as needed, but caution is advised.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment due to minimal systemic absorption.
## Contraindications
* Allergy to liquid paraffin.
* Acute appendicitis, intestinal obstruction, or undiagnosed abdominal pain.
* Inhalation of liquid paraffin can cause lipoid pneumonia; caution in patients with dysphagia or gastroesophageal reflux.
## Adverse Effects
* Diarrhea, abdominal cramping, nausea.
* Anal leakage or seepage (especially with higher doses).
* **Long-term, high-dose use:** May interfere with the absorption of fat-soluble vitamins (A, D, E, K).
* **Aspiration:** Can lead to lipoid pneumonia, a serious and potentially fatal condition.
## Key Drug Interactions
* Concurrent use with other medications that can cause constipation may reduce their absorption.
* May decrease the absorption of oral anticoagulants if taken concurrently.
## Monitoring
* Bowel movements and stool consistency.
* Signs of abdominal discomfort.
* Monitor for vitamin deficiencies with chronic use.
## Clinical Pearls
* Administer at bedtime to minimize daytime seepage.
* Advise patients to remain in an upright position for at least 30 minutes after administration to reduce aspiration risk.
* Not for chronic use due to potential for vitamin malabsorption and dependence.
* In children, especially those with swallowing difficulties, the risk of aspiration and lipoid pneumonia is a significant concern.
