NutriLipid I.V. Fat Emulsion

5 WARNINGS AND PRECAUTIONS 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. 5.9 Monitoring / Laboratory Tests Monitor fluid status closely in patients with pulmonary edema or heart failure. Throughout treatment, monitor serum triglycerides [see Warnings and Precautions (5.7) ] , fluid and electrolyte status, serum osmolarity, blood glucose, liver and kidney function, blood count (including platelets), and coagulation parameters. The lipids contained in Nutrilipid may interfere with some laboratory tests (e.g., hemoglobin, lactate dehydrogenase, bilirubin, oxygen saturation) if blood is sampled before the lipids have cleared from the bloodstream. Conduct these tests at least 6 hours after stopping the infusion. Nutrilipid contains Vitamin K that may counteract anticoagulant activity [see Drug Interactions (7) ].
