# Liquid Paraffin + Milk of Magnesia + Sodium Picosulphate
## Overview
This combination product is typically used as a laxative for the relief of constipation. Liquid paraffin acts as a lubricant laxative, softening stool. Milk of magnesia is an osmotic laxative, drawing water into the intestines. Sodium picosulphate is a stimulant laxative, increasing intestinal motility.
## Primary Indications
* Constipation
## Adult Dosing
* **Dosing varies significantly by product formulation.** Always refer to the specific product's labeling.
* A common starting regimen may involve doses such as:
* Liquid paraffin: 5-15 mL orally once daily.
* Milk of Magnesia: 15-30 mL orally once daily.
* Sodium picosulphate: 5-10 mg orally once daily, often taken at bedtime.
* Maximum daily doses should not be exceeded and are formulation-specific.
## Pediatric Dosing
* **Use in children is generally not recommended unless specifically advised by a healthcare professional.**
* Dosing, if prescribed, will be highly dependent on the child's age and weight and the specific product formulation. Refer to pediatric-specific product labeling or clinical guidelines.
## Dose Adjustments
* No specific dose adjustments for renal or hepatic impairment are typically listed for these individual agents in combination products, but caution is advised.
## Contraindications
* Bowel obstruction
* Appendicitis or symptoms of acute abdominal conditions
* Intestinal perforation
* Severe dehydration
* Known hypersensitivity to any component.
## Adverse Effects
* Abdominal cramps, pain, bloating
* Diarrhea
* Nausea, vomiting
* Electrolyte imbalance (with excessive or prolonged use)
* Anal leakage (with liquid paraffin)
* Dehydration
## Key Drug Interactions
* **Antibiotics:** May reduce absorption of certain antibiotics. Separate administration by at least 2 hours.
* **Digoxin:** Electrolyte imbalances can increase sensitivity to digoxin.
* **Other Laxatives:** Concurrent use may lead to excessive fluid loss and electrolyte imbalance.
* **Fat-soluble Vitamins:** Liquid paraffin may impair the absorption of fat-soluble vitamins (A, D, E, K).
## Monitoring
* Monitor for effectiveness and adverse effects (e.g., abdominal pain, diarrhea, dehydration).
* Monitor electrolytes if symptoms suggest imbalance or with prolonged use.
## Clinical Pearls
* This combination aims to provide a multi-mechanistic approach to constipation relief.
* Ensure adequate fluid intake when using these products to prevent dehydration.
* Avoid prolonged use. If constipation persists, medical evaluation is necessary.
* Liquid paraffin can be aspirated if taken incorrectly, especially in recumbent or elderly patients, leading to lipid pneumonia; administer with caution.
