# Liquid Paraffin
## Overview
Liquid paraffin is a mineral oil used as a laxative. It lubricates the intestinal tract, softening stool and facilitating its passage. It is poorly absorbed from the gastrointestinal tract.
## Primary Indications
* **Constipation:** Relief of occasional constipation.
## Adult Dosing
* **Oral:** 10-30 mL once daily, typically at bedtime. The dose may be adjusted based on individual response. Do not exceed the recommended dose without medical advice.
## Pediatric Dosing
* **Children 6 years and older:** 5-10 mL once daily.
* **Children under 6 years:** Not recommended without medical supervision. Dosing may be determined by a healthcare provider based on weight and clinical assessment.
## Dose Adjustments
No dose adjustments are typically required for hepatic or renal impairment due to minimal systemic absorption.
## Contraindications
* Patients with hypersensitivity to liquid paraffin.
* Patients with intestinal obstruction, appendicitis, or inflammatory bowel disease.
* Patients with acute abdominal pain or unexplained gastrointestinal bleeding.
* Use with caution in individuals at risk of aspiration, especially the elderly or those with swallowing difficulties, due to the risk of lipid pneumonitis.
## Adverse Effects
* **Gastrointestinal:** Anal leakage (especially with higher doses), abdominal cramping, nausea, vomiting, diarrhea.
* **Long-term use:** May lead to reduced absorption of fat-soluble vitamins (A, D, E, K), potentially causing vitamin deficiencies. Pruritus ani (anal itching).
## Key Drug Interactions
* **Fat-soluble vitamin absorption:** Concurrent use with liquid paraffin may decrease the absorption of fat-soluble vitamins (A, D, E, K). Administration of vitamins should be spaced several hours apart from liquid paraffin.
* **Other medications:** May reduce the absorption of other orally administered medications due to its laxative effect and potential to coat the intestinal lining. Consider spacing administration of other oral drugs by at least 2 hours.
## Monitoring
* Monitor for bowel movement frequency and consistency.
* Assess for abdominal discomfort or cramping.
* Observe for any signs of anal leakage.
* In patients using long-term, consider monitoring for signs of fat-soluble vitamin deficiency.
## Clinical Pearls
* Liquid paraffin is a lubricant laxative and works by softening and coating the stool.
* It is generally not recommended for chronic use due to potential for vitamin malabsorption and dependence.
* Administer at bedtime to minimize disruption.
* Ensure adequate fluid intake when using laxatives.
* Risk of aspiration and lipid pneumonia exists, particularly in the supine position or with impaired swallowing reflexes. Advise patients to remain upright for at least 1 hour after taking.
