# Liquid Paraffin
## Overview
Liquid paraffin is a mineral oil used as a lubricant laxative. It coats the intestinal wall, softening the stool and facilitating bowel movements. It is poorly absorbed from the gastrointestinal tract.
## Primary Indications
* Constipation
## Adult Dosing
* **Oral:** 10 mL to 30 mL once daily, typically at bedtime. Dosing can be adjusted based on patient response.
## Pediatric Dosing
* **Oral:** Dosing is not well-established in children under 12 years of age. If used, a dose of 5 mL once daily may be considered for children aged 6-12 years, under strict medical supervision. Safety and efficacy in younger children have not been established.
## Dose Adjustments
* No dose adjustments are typically required for renal or hepatic impairment, as absorption is minimal.
## Contraindications
* Hypersensitivity to liquid paraffin.
* Intestinal obstruction, appendicitis, inflammatory bowel disease, or severe abdominal pain.
* Difficulty swallowing due to risk of aspiration and lipid pneumonia.
## Adverse Effects
* Diarrhea, abdominal cramping, nausea, vomiting.
* Anal leakage (especially with higher doses).
* **Most serious:** Lipid pneumonia if aspirated.
* Long-term use may lead to dependence and decreased bowel tone.
* Reduced absorption of fat-soluble vitamins (A, D, E, K) with chronic use.
## Key Drug Interactions
* **Mineral Oil:** Concomitant use with other mineral oil-containing products should be avoided.
* **Docusate Sodium:** May enhance the effect of mineral oil.
* **Fat-soluble Vitamins:** Reduced absorption may occur with chronic use.
## Monitoring
* Bowel movement frequency and consistency.
* Signs of abdominal discomfort or obstruction.
* For signs of aspiration or lipid pneumonia, especially in elderly or debilitated patients, or those with impaired swallowing.
## Clinical Pearls
* Administer at bedtime to minimize daytime leakage and maximize overnight efficacy.
* Do not lie down immediately after taking the dose to reduce the risk of aspiration.
* Warn patients about potential anal leakage, especially with higher doses, and suggest using a protective pad.
* Not recommended for long-term treatment of constipation. Consider alternative laxatives for chronic use.
* Use with extreme caution in infants, the elderly, and those with a risk of aspiration.
