NORMOCARB HF™ contains no bacteriostatic or antimicrobial agents.
Indications
NORMOCARB HF™, after dilution, is indicated in adult and pediatric patients for use as a replacement solution in Continuous Renal Replacement Therapy (CRRT) to replace water and to correct electrolytes and acid-base imbalance.
Dosage And Administration
Important Preparation Information
NORMOCARB HF MUST BE DILUTED BEFORE USE. Dilute only with Sterile Water for Injection. For dilution, add one 240 mL vial of NORMOCARB HF to 3 Liters of Sterile Water for Injection to make 3.24 Liters of infusate solution. Shake to mix by rocking or rolling the bag and contents thoroughly. Additives can be introduced after initial dilution [see Additives].
Individualization Of Treatment
Pre-or Post-Filter: The volume of solution (diluted NORMOCARB HF™) administered depends upon the fluid balance of the individual patient, the target fluid balance to be achieved, the body weight and the amount of fluid removed from the patient’s circulation during the hemofiltration process. When administered post-filter, the replacement rate should not be greater than one third of the blood flow rate; e.g., for blood flow of 100 mL per min, equivalent to 6000 mL per hour, post-filter replacement rate should not exceed 2000 mL per hour.
Administration
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use NORMOCARB HF if a precipitate has been formed or if container seals have been damaged.
Table 1 describes the components of diluted NORMOCARB HF 25 and NORMOCARB HF 35 solutions when prepared as directed.

Precautions
Serious Electrolyte, Acid-base, Glucose And Fluid Imbalances
Fluid imbalance and electrolyte, acid-base, and glucose disturbances can occur during therapy. Monitor the patient’s hemodynamic status, and fluid, electrolyte, glucose and acid-base balance throughout the procedure.
Use In Specific Populations
Pregnancy
Risk Summary
NORMOCARB HF is a pharmacologically inactive solution. While there are no adequate and well-controlled studies in pregnant women, appropriate administration of NORMOCARB HF with monitoring of fluid, electrolyte, acid-base and glucose balance, is not expected to cause fetal harm, or affect reproductive capacity. Animal reproduction studies have not been conducted with NORMOCARB HF™.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Lactation
Risk Summary
The components of NORMOCARB HF are excreted in human milk. Appropriate administration of NORMOCARB HF with monitoring of fluid, electrolyte, acid-base and glucose balance is not expected to harm a nursing infant.
Pediatric Use
No adequate and well-controlled studies have been conducted with NORMOCARB HF in adult or pediatric patients. Safety and effectiveness in pediatric patients newborn to 17 years of age were based on eight non-controlled published pediatric studies and one published pediatric scientific literature review. The exact composition of the buffer and electrolytes in the solution during CRRT were not described in adult or pediatric studies; however, plasma electrolyte levels were similar between adults and children.
Geriatric Use
No adequate and well-controlled studies have been conducted with NORMOCARB HF in elderly patients.
Overdose
No information provided.
Contraindications
None.
Clinical Pharmacology
Mechanism Of Action
NORMOCARB HF is a pharmacologically inactive solution. The concentrations of electrolytes are chosen to help to restore plasma levels to physiological concentrations.
NORMOCARB HF is used as replacement solution to replace water and electrolytes removed during hemofiltration and hemodiafiltration.
Bicarbonate in the solution is used as an alkalinizing buffer to normalize acid-base balance.
