Nutrilipid 20% injection is contraindicated in patients who have: Known hypersensitivity to egg, soybean, peanut, or any of the active or inactive ingredients in Nutrilipid 20% [see Warnings and Precautions (5.3) ]. Severe disorders of lipid metabolism characterized by hypertriglyceridemia (serum triglyceride >1,000 mg/dL) [see Warnings and Precautions (5.7) ]. Known hypersensitivity to egg, soybean, peanut, or any of the active or inactive ingredients. ( 4 ) Severe disorders of lipid metabolism characterized by hypertriglyceridemia (serum triglycerides >1,000 mg/dL). ( 4, 5.7 )

Clinical Decompensation with Rapid Infusion of Intravenous Lipid Emulsion in Neonates and Infants : Acute respiratory distress, metabolic acidosis, and death after rapid infusion of intravenous lipid emulsions have been reported. ( 5.1, 8.4 ) Parenteral Nutrition-Associated Liver Disease : Increased risk in patients who receive parenteral nutrition for greater than 2 weeks, especially preterm neonates. Monitor liver tests; if abnormalities occur, consider discontinuation or dosage reduction. ( 5.2, 8.4 ) Hypersensitivity reactions: Monitor for signs or symptoms. Discontinue infusion if reactions occur. ( 5.3 ) Infections, Fat Overload Syndrome, and Refeeding Syndrome, Hypertriglyceridemia: Monitor for signs and symptoms; monitor laboratory parameters. ( 5.4 , 5.5 , 5.6, 5.7 ) Aluminum Toxicity : Increased risk in patients with renal impairment, including preterm neonates. ( 5.8, 8.4 )

5.1 Clinical Decompensation with Rapid Infusion of Intravenous Lipid Emulsion in Neonates and Infants In the postmarketing setting, serious adverse reactions including acute respiratory distress, metabolic acidosis, and death have been reported in neonates and infants after rapid infusion of intravenous lipid emulsions. Hypertriglyceridemia was commonly reported. Strictly adhere to the recommended total daily dosage; the hourly infusion rate should not exceed 0.75 mL/kg/hour [see Dosage and Administration (2.4) ]. Preterm and small for gestational age infants have poor clearance of intravenous lipid emulsion and increased free fatty acid plasma levels following lipid emulsion infusion. Carefully monitor the infant’s ability to eliminate the infused lipids from the circulation (e.g., measure serum triglycerides and/or plasma free fatty acid levels). If signs of poor clearance of lipids from the circulation occur, stop the infusion and initiate a medical evaluation [see Warnings and Precautions (5.5, 5.7) and Overdosage (10) ].

5.2 Parenteral Nutrition-Associated Liver Disease and Other Hepatobiliary Disorders Risk of Parenteral Nutrition-Associated Liver Disease Parenteral nutrition-associated liver disease (PNALD), also referred to as intestinal failure-associated liver disease (IFALD), can present as cholestasis or hepatic steatosis, and may progress to steatohepatitis with fibrosis and cirrhosis (possibly leading to chronic hepatic failure). The etiology of PNALD is multifactorial; however, intravenously administered phytosterols (plant sterols) contained in plant-derived lipid emulsions, including Nutrilipid 20%, have been associated with development of PNALD. Monitor liver tests in patients treated with Nutrilipid 20% and consider discontinuation or dosage reduction if abnormalities occur. Other Hepatobiliary Disorders Hepatobiliary disorders including cholecystitis and cholelithiasis have developed in some PN-treated patients without preexisting liver disease. Monitor liver tests when administering Nutrilipid 20%. Patients developing signs of hepatobiliary disorders should be assessed early to determine whether these conditions are related to Nutrilipid 20% use.

5.3 Hypersensitivity Reactions Nutrilipid 20% contains soybean oil and egg phospholipids which may cause hypersensitivity reactions. Cross reactions have been observed between soybean and peanut. In postmarketing experience, anaphylaxis has been reported following Nutrilipid administration [see Adverse Reactions (6.2) ]. Nutrilipid 20% is contraindicated in patients with known hypersensitivity to egg, soybean, peanut, or any of the active or inactive ingredients in Nutrilipid 20% [see Contraindications (4)] . If a hypersensitivity reaction occurs, stop infusion of Nutrilipid 20% immediately and initiate appropriate treatment and supportive measures.

5.4 Infections Lipid emulsions, such as Nutrilipid 20%, can support microbial growth and are an independent risk factor for the development of catheter-related bloodstream infections. To decrease the risk of infectious complications, ensure aseptic techniques are used for catheter placement, catheter maintenance, and preparation and administration of Nutrilipid 20%. Monitor for signs and symptoms of infection, including fever and chills, as well as including laboratory test results (including leukocytosis and hyperglycemia). Perform frequent checks of the intravenous catheter insertion site for edema, redness, and discharge.

5.5 Fat Overload Syndrome Fat overload syndrome is a rare condition that has been reported with intravenous lipid formulations and is characterized by a sudden deterioration in the patient's condition (e.g., fever, anemia, leukopenia, thrombocytopenia, coagulation disorders, hyperlipidemia, hepatomegaly, deteriorating liver function, and central nervous system manifestations such as coma). A reduced or limited ability to metabolize lipids, accompanied by prolonged plasma clearance (resulting in higher lipid levels), may result in this syndrome. Although fat overload syndrome has been most frequently observed when the recommended lipid dose or infusion rate was exceeded, cases have also been described when the lipid formulation was administered according to instructions. If signs or symptoms of fat overload syndrome occur, stop Nutrilipid 20%. The syndrome is usually reversible when the infusion of the lipid emulsion is stopped.

5.6 Refeeding Syndrome Administering PN to severely malnourished patients may result in the refeeding syndrome, which is characterized by the intracellular shift of potassium, phosphorus, and magnesium as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. To prevent these complications, closely monitor severely malnourished patients and slowly increase their nutrient intake.

5.7 Hypertriglyceridemia The use of Nutrilipid 20% is contraindicated in patients with hypertriglyceridemia with serum triglyceride concentrations >1,000 mg/dL. Patients with conditions such as inherited lipid disorders, obesity, diabetes mellitus, or metabolic syndromes have a higher risk of developing hypertriglyceridemia with the use of Nutrilipid 20%. In addition, patients with hypertriglyceridemia may have worsening of their hypertriglyceridemia with administration of Nutrilipid 20%. Excessive dextrose administration may further increase such risk. Evaluate patients’ capacity to metabolize and eliminate the infused lipid emulsion by measuring serum triglycerides before the start of infusion (baseline value) and regularly throughout treatment. If triglyceride levels are above 400 mg/dL in adults, stop the Nutrilipid 20% infusion and monitor serum triglyceride levels to avoid clinical consequences of hypertriglyceridemia such as pancreatitis. In pediatric patients with hypertriglyceridemia, lower triglyceride levels (i.e., below 400 mg/dL) may be associated with adverse reactions. Monitor serum triglyceride levels to avoid potential complications with hypertriglyceridemia such as pancreatitis, lipid pneumonitis, and neurologic changes, including kernicterus. To minimize the risk of new or worsening of hypertriglyceridemia, assess high-risk patients for their overall energy intake including other sources of lipids and dextrose, as well as concomitant drugs that may affect lipid and dextrose metabolism.

5.8 Aluminum Toxicity Nutrilipid 20% contains no more than 25 mcg/L of aluminum. Prolonged parenteral nutrition administration in patients with renal impairment may result in aluminum reaching toxic levels. Preterm infants are at greater risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions that contain aluminum. Patients with impaired kidney function, including preterm infants, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day, accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration of total parenteral nutrition products. […]

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions reported with other intravenous lipid emulsions include hyperlipidemia, hypercoagulability, thrombophlebitis, and thrombocytopenia. Adverse reactions reported in long-term use with other intravenous lipid emulsions include hepatomegaly, jaundice due to central lobular cholestasis, splenomegaly, thrombocytopenia, leukopenia, abnormalities in liver function tests, brown pigmentation of the liver and overloading syndrome (focal seizures, fever, leukocytosis, hepatomegaly, splenomegaly and shock).

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of Nutrilipid 20%. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General disorders and administration site conditions: extravasation, infusion site erythema, infusion site pain, infusion site phlebitis, infusion site pruritus, and infusion site swelling. Immune system disorders: hypersensitivity reactions, including anaphylaxis [see Contraindications (4) , Warnings and Precautions (5.3) ].

Coumarin and coumarin derivatives, including warfarin: Anticoagulant activity may be counteracted; monitor laboratory parameters (7.1)

7.1 Coumarin and Coumarin Derivatives The soybean oil in Nutrilipid 20% contains vitamin K1. Vitamin K can reverse the anticoagulant activity of coumarin and coumarin derivatives, including warfarin, which work by blocking recycling of vitamin K. Monitor laboratory parameters for anticoagulant activity in patients who are on both Nutrilipid 20% and coumarin or coumarin derivatives.

8.1 Pregnancy Risk Summary There are no adequate or well controlled studies with Nutrilipid 20% in pregnant women. Additionally, animal reproduction studies have not been conducted with Nutrilipid 20%. It is not known whether Nutrilipid 20% can cause fetal harm when administered to a pregnant woman. Nutrilipid 20% should be given to a pregnant woman only if clearly needed.

8.3 Nursing Mothers It is not known whether Nutrilipid 20% is present in human milk. Because many drugs are present in human milk, caution should be exercised when Nutrilipid 20% is administered to a nursing woman.

8.4 Pediatric Use The evidence for safety and efficacy in pediatric patients of Nutrilipid 20% as a source of calories and essential fatty acids for parenteral nutrition and as a source of essential fatty acids when a deficiency occurs when oral or enteral nutrition is not possible, insufficient, or contraindicated is derived from the published literature and clinical experience with similar soybean oil-based intravenous lipid emulsions. In the postmarketing setting, clinical decompensation with rapid infusion of intravenous lipid emulsion in neonates and infants, sometimes fatal, has been reported [see Warnings and Precautions (5.1) ]. Patients, particularly preterm infants, are at risk for aluminum toxicity [see Warnings and Precautions (5.9) ] . Patients, including pediatric patients, may be at risk for PNALD [see Warnings and Precautions (5.2) ] . In clinical trials of a pure soybean oil based intravenous lipid emulsion product, thrombocytopenia in neonates occurred (less than 1%).

8.5 Geriatric Use Clinical studies of Nutrilipid 20% did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Nutrilipid 20% administered intravenously provides biologically utilizable source of calories and essential fatty acids. Fatty acids serve as an important substrate for energy production. The most common mechanism of action for energy production derived from fatty acid metabolism is beta oxidation. Fatty acids are important for membrane structure and function, precursors for bioactive molecules (such as prostaglandins), and as regulators of gene expression. Nutrilipid 20% causes an increase in heat production, decrease in respiratory quotient, and increase in oxygen consumption following its administration.
