# Liquid Paraffin + Milk of Magnesia + Sodium Picosulfate
## Overview
This combination is a laxative formulation used for the relief of constipation. It contains a stool softener (liquid paraffin), an osmotic laxative (milk of magnesia), and a stimulant laxative (sodium picosulfate).
## Primary Indications
Short-term relief of occasional constipation.
## Adult Dosing
* **Typical Dose:** 15 mL to 30 mL once daily at bedtime.
* **Maximum Dose:** Specific maximums are not universally established and depend on the preparation's concentration and patient response. Dosing should be individualized and not exceed recommended package instructions.
## Pediatric Dosing
Dosing in children is generally **not recommended** due to lack of established safety and efficacy data for this specific combination, and the availability of safer alternatives. If used, follow strict medical guidance. Some preparations may state age restrictions (e.g., typically not for children under 12 years) on their labeling.
## Dose Adjustments
No specific dose adjustments are generally required for hepatic or renal impairment, but caution and medical guidance are advised due to potential electrolyte disturbances with prolonged use.
## Contraindications
* Known hypersensitivity to any component of the formulation.
* Appendicitis or symptoms of appendicitis.
* Intestinal obstruction, fecal impaction, or un-diagnosed abdominal pain.
* Severe dehydration.
* Conditions where increased peristalsis may be harmful (e.g., inflammatory conditions of the gastrointestinal tract).
## Adverse Effects
Common: Abdominal cramps, diarrhea, nausea, vomiting, electrolyte imbalance (especially with overuse).
Less common: Rectal irritation, malabsorption of fat-soluble vitamins (due to liquid paraffin).
## Key Drug Interactions
* **Antibiotics:** May reduce absorption of some antibiotics due to altered GI transit time and pH.
* **Digoxin:** Hypokalemia induced by laxatives can increase the risk of digoxin toxicity.
* **Diuretics and Corticosteroids:** Increased risk of electrolyte imbalance.
* **Mineral Oil:** Concurrent use with liquid paraffin can increase systemic absorption and risk of adverse effects.
## Monitoring
* Hydration status.
* Electrolyte levels (especially with chronic or excessive use).
* Bowel function and absence of abdominal pain.
## Clinical Pearls
* Administer with a full glass of water to promote hydration and efficacy.
* Avoid prolonged use (typically recommended for no more than 7 days) as it may lead to dependence and electrolyte disturbances.
* Liquid paraffin should be taken separately from other oral medications by at least 2 hours, as it can interfere with the absorption of certain drugs. It is also a potential aspiration risk if taken improperly or by individuals with impaired swallowing reflexes.
* Sodium picosulfate is a prodrug that is hydrolyzed by intestinal bacteria to its active form.
