Single-dose vial, for admixture use only. ( 2.1 ) See full prescribing information for information on preparation, administration and general dosing considerations. ( 2.1 , 2.2 , 2.3 , 2.4 ) Recommended Dosage Each mL of Multrys provides zinc 1,000 mcg, copper 60 mcg, manganese 3 mcg, and selenium 6 mcg. ( 2.5 ) Multrys is recommended only for pediatric patients who require supplementation with all four of the individual trace elements (i.e., zinc, copper, manganese, and selenium) to meet daily requirements. ( 2.5 ) Pediatric Patients 0.4 kg to 0.59 kg : The total recommended dosage of Multrys is 0.2 mL every other day .Daily supplementation of Zinc Sulfate, Cupric Chloride and Selenious Acid will be needed to meet daily requirements. ( 2.5 ) Pediatric Patients 0.6 kg to 10 kg : The recommended dosage of Multrys is 0.3 mL/kg/day rounded to the nearest 0.1 mL for up to a maximum of 1 mL per day. The recommended volume of Multrys to be added to parenteral nutrition ranges from 0.2 mL per day to 1 mL per day based on body weight. ( 2.5 ) Multrys is not recommended for patients who may require a lower dosage of one or more of the individual trace elements. ( 2.5 ) Monitor trace element concentrations in blood during long-term administration of parenteral nutrition. ( 2.5 ) 2.1 Important Administration Information Multrys is supplied as a single-dose vial for admixture use only. Prior to administration, Multrys must be transferred to a separate parenteral nutrition container and used as an admixture in parenteral nutrition solution. The final parenteral nutrition solution is for intravenous infusion into a central or peripheral vein. The choice of a central or peripheral venous route should depend on the osmolarity of the final infusate. Solutions with osmolarity of 900 mOsmol/L or greater must be infused through a central catheter [see Warnings and Precautions ( 5.2 )] . 2.2 Preparation and Administration Instructions Multrys is for admixture use only.Prior to administration, Multrys must be prepared and used as an admixture in parenteral nutrition solution. Add Multrys to the parenteral nutrition solution in a suitable work area such as a laminar flow hood (or an equivalent clean air compounding area).The key factor in the preparation is careful aseptic technique to avoid inadvertent touch contamination during mixing of solutions and addition of other nutrients. Inspect the parenteral nutrition solution containing Multrys for particulate matter before admixing, after admixing, and prior to administration. 2.3 Preparation Instructions for Admixing Using a Parenteral Nutrition Container Inspect Multrys single-dose vial for particulate matter. Transfer Multrys to the parenteral nutrition container after the admixture of amino acids, dextrose, lipid emulsion (if added), and electrolyte solutions is prepared. Because additives may be incompatible, evaluate all additions to the parenteral nutrition container for compatibility and stability of the resulting preparation.Consult with a pharmacist, if available.For introducing additives to the parenteral nutrition container, use aseptic technique. An interaction may occur between cupric ion and ascorbic acid; therefore, multivitamin additives should be added to the admixed parenteral nutrition solution shortly before infusion. Inspect the final parenteral nutrition solution containing Multrys to ensure that: Precipitates have not formed during mixing or addition of additives. The emulsion has not separated, if lipid emulsion has been added.Separation of the emulsion can be visibly identified by a yellowish streaking or the accumulation of yellowish droplets in the admixed emulsion. Discard if any precipitates are observed. Stability and Storage Single dose vial.Discard any unused portion. Penetrate vial closure only one time with a suitable sterile transfer device or dispensing set that allows measured dispensing of the contents. Transfer Multrys to the parenteral nutrition container promptly after removal from the vial. Discard any remaining drug. Use parenteral nutrition solutions containing Multrys promptly after mixing.Any storage of the admixture should be under refrigeration from 2ºC to 8ºC (36ºF to 46ºF) and limited to a period of no longer than 9 days.After removal from refrigeration, use promptly and complete the infusion within 24 hours. Discard any remaining admixture. Protect the parenteral nutrition solution from light. 2.4 Overview of Dosing Prior to administration of parenteral nutrition solution containing Multrys, correct severe fluid, electrolyte, and acid-base disorders. The dosage of the final parenteral nutrition solution containing Multrys must be based on the concentrations of all components in the solution, the patient’s clinical condition, nutritional requirements, and the contribution of oral or enteral intake. Monitor fluid and electrolyte status during treatment use of Multrys and adjust the parenteral nutrition solution as needed. 2.5 Recommended Dosage in Pediatric Patients and Monitoring Considerations Multrys is a fixed-combination product. Each mL of Multrys provides zinc 1,000 mcg, copper 60 mcg, manganese 3 mcg, and selenium 6 mcg. Recommended Dosage for Pediatric Patients Weighing 0.4 kg to 0.59 kg The total recommended dosage of Multrys is 0.2 mL every other day. Daily supplementation of Zinc, Copper, and Selenium will be needed to meet daily requirements (See Table 2 below). Recommended Dosage f or Pediatric Patients Weighing 0.6 kg to less than 10 kg The recommended dosage of Multrys is 0.3 mL/kg/day rounded to nearest 0.1 mL for up to a maximum of 1 mL per day. The recommended volume of Multrys to be added to parenteral nutrition ranges from 0.2 mL per day to 1 mL per day based on body weight, see Table 1 below. Table 1.
