Warnings & precautions
Sourced from openFDA• Risk of Aluminum Toxicity: For at risk patients (renal failure or those with prolonged therapy), consider periodic monitoring of aluminum levels ( 5.1 ) • Allergic Reactions: To thiamine may occur ( 5.2 ) • Hypervitaminosis A : Patients with renal failure or liver disease may be at higher risk ( 5.3 ) • Decreased Anticoagulant Effect of Warfarin: Monitor INR ( 5.4 , 7.1 ) • Interferes with Megaloblastic Anemia Diagnosis: Avoid during testing for this disorder ( 5.5 ) • Risk of Vitamin Deficiencies or Excesses: Monitor blood vitamin concentrations ( 5.6 ) • False Negative Urine Glucose Tests: Due to vitamin C ( 5.7 ) • Risk of Vitamin E Toxicity: Additional oral and parenteral vitamin E may result in elevated vitamin E blood concentrations in infants ( 5.8 ) • Low Vitamin A Levels: Monitor vitamin A levels ( 5.9 ) • Risk of E-Ferol Syndrome: Due to polysorbates ( 5.10 ) 5.1 Aluminum Toxicity INFUVITE PEDIATRIC contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration in pediatric patients with renal impairment. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solution, which contain aluminum. Research indicates that patients with impaired kidney function, including premature neonates 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.
Adverse reactions
Sourced from openFDAThe following adverse reactions are discussed in greater detail in other sections of the labeling. • Allergic reactions to thiamine [ see Warnings and Precautions ( 5.2 ) ]. • Hypervitaminosis A [ see Warnings and Precautions ( 5.3 ) ] The following adverse reactions have been identified during postapproval use of INFUVITE PEDIATRIC. 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. Dermatologic: rash, erythema, pruritis CNS: headache, dizziness, agitation, anxiety Ophthalmic: diplopia Adverse reactions have included anaphylaxis, rash, erythema, pruritis, headache, dizziness, agitation, anxiety, diplopia ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Sandoz Inc. at 1-800-525-8747 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Use in specific populations
Sourced from openFDA• Renal Impairment: Monitor renal function, calcium, phosphorus and vitamin A levels ( 8.6 ) • Hepatic Impairment: Monitor vitamin A levels ( 8.7 ) 8.1 Pregnancy Pregnancy Category C. INFUVITE PEDIATRIC has not been studied in pregnant women. Pregnant women should follow the U.S. recommended daily allowances for pregnancy because their vitamin requirements may exceed those of non-pregnant women. Animal reproduction studies have not been conducted with INFUVITE PEDIATRIC (multiple vitamins injection). 8.3 Nursing Mothers INFUVITE PEDIATRIC has not been studied in nursing mothers. Lactating women may have vitamin requirements that exceed those of non-lactating women. Caution should be exercised when INFUVITE PEDIATRIC is administered to nursing mothers. 8.4 Pediatric Use INFUVITE PEDIATRIC is approved for the prevention of vitamin deficiency in pediatric patients up to 11 years old receiving parenteral nutrition. INFUVITE PEDIATRIC has not been studied in pediatric patients older than 11 years. INFUVITE PEDIATRIC contains aluminum that may be toxic for premature neonates. Aluminum levels should be monitored periodically during administration of INFUVITE PEDIATRIC to premature neonates [ see Warnings and Precautions ( 5.1 ) ].
Overdosage
Sourced from openFDASigns and symptoms of acute or chronic overdosage may be those of individual INFUVITE PEDIATRIC component toxicity. There is no clinical experience with INFUVITE PEDIATRIC overdosage.
