Intralipid (Soya Oil, Purified)

Intralipid is used in clinical situations that require intravenous lipid nutrition or a solubilizing vehicle for lipophilic drugs.

• Parenteral nutrition (patients unable to receive enteral feeding): supplies calories and essential fatty acids to meet nutritional requirements.
• Essential fatty acid deficiency (prevention and treatment): restores deficient omega‑3 and omega‑6 fatty acids.
• Intravenous drug vehicle (lipophilic medications): acts as a carrier to solubilize and deliver poorly water‑soluble drugs.

• Intralipid delivers triglyceride‑rich soybean oil particles that are hydrolyzed by lipases to free fatty acids, providing a rapid energy source and essential fatty acids for phospholipid membrane synthesis. The emulsion circulates in the plasma, allowing cellular uptake of fatty acids for metabolic processes and supporting membrane integrity in rapidly dividing or damaged cells.

Adverse reactions may occur with intravenous lipid emulsions and should be monitored.

Common Side Effects

• Fever or chills during infusion
• Mild hypotension or transient blood pressure changes
• Elevated triglyceride levels
• Infusion site pain or erythema
• Mild respiratory discomfort

Serious or Rare Side Effects

• Fat overload syndrome leading to organ dysfunction
• Pulmonary embolism or severe respiratory distress
• Anaphylactic or severe allergic reactions
• Hepatic dysfunction with prolonged use
• Coagulopathy or platelet aggregation abnormalities

Intralipid requires careful patient assessment and monitoring to minimize risks.

• Baseline triglyceride assessment: measure serum triglycerides before initiating therapy.
• Liver function monitoring: check hepatic enzymes regularly during prolonged use.
• Lipid metabolism disorders: avoid or adjust dosing in patients with known disorders.
• Hypersensitivity: do not use in individuals with documented soy or egg protein allergy.
• Concomitant lipid sources: limit simultaneous administration of other lipid emulsions.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Intralipid can interact with other agents that affect lipid metabolism or coagulation.

Major Interactions (Avoid)

• Concurrent lipid emulsions (e.g., propofol): risk of severe hypertriglyceridemia and fat overload.
• High‑dose corticosteroids: synergistic increase in serum triglycerides.

Moderate Interactions (Monitor Closely)

• Anticoagulants (warfarin, heparin): potential alteration of clotting parameters.
• Certain antibiotics (e.g., ceftriaxone): may precipitate when mixed with lipid emulsions.
• Parenteral nutrition electrolytes: monitor for compatibility and electrolyte shifts.
