Albumin and alpha 1-macroglobulin (Foote 1984).
Use: Labeled Indications
Trace element added to parenteral nutrition (PN) to prevent deficiency; orally as a dietary supplement.
Injection: Hypersensitivity to zinc or any component of the formulation.
Dietary supplement: Oral: 50 mg (dose expressed as elemental zinc) once daily.
Parenteral nutrition additive, maintenance requirement: IV (dose expressed as elemental zinc): Note: Individualize dose based on the patient's clinical condition, nutritional requirements, and the contribution of oral or enteral zinc intake.
Acute metabolic states: Optimal dose not determined; monitor and replace as clinically indicated (Blaauw 2019).
Metabolically stable: 3 to 5 mg/day (ASPEN 2019).
Replacement for small bowel fluid loss (metabolically stable): Additional zinc replacement may be required for patients with intestinal fistula, ostomy effluent, or severe diarrhea due to excessive zinc losses. Estimated losses range from up to 12 mg zinc/L for GI fluid loss and up to 17 mg zinc/L for stool or ileostomy output (Blaauw 2019; Vanek 2012).
Zinc deficiency (Saper 2009): Oral: Some clinicians recommend daily doses of 2 to 3 times the zinc RDA for mild deficiency and 4 to 5 times the RDA for moderate to severe deficiency for 6 months.
Refer to adult dosing.
Note: Dosages may be presented in units of mcg or mg; use caution to ensure correct units.
Parenteral nutrition, maintenance zinc requirement:
Note: Dosage expressed in terms of elemental zinc; higher doses may be needed (in some cases between 2 to 3 times the maintenance requirement) if impaired intestinal absorption or an excessive loss of zinc (eg, excessive, prolonged diarrhea; high-output intestinal fistula; burns) (AAP [Kleinman 2019]).

Consider therapy modification
Tetracyclines: Zinc Salts may decrease the absorption of Tetracyclines. Only a concern when both products are administered orally. Management: Consider doxycycline as a noninteracting tetracycline derivative. Separate dose administration of oral tetracycline derivative and oral zinc salts by at least 2 hours to minimize interaction. Exceptions: Doxycycline; Eravacycline; Tigecycline. Consider therapy modification
Trientine: Polyvalent Cation Containing Products may decrease the serum concentration of Trientine. Management: Avoid concomitant administration of trientine and oral products that contain polyvalent cations. If oral iron supplements are required, separate the administration by 2 hours. If other oral polyvalent cations are needed, separate administration by 1 hour. Consider therapy modification
There are no adverse reactions listed in the manufacturer's labeling.
• Renal impairment: Use with caution in patients with renal impairment.
Concurrent drug therapy issues:
• Copper: IV administration of zinc without copper may cause a decrease in copper serum concentrations.
Dosage form specific issues:
• Aluminum: The parenteral product may contain aluminum; toxic aluminum concentrations may be seen with high doses, prolonged use, or renal dysfunction. Premature neonates are at higher risk due to immature renal function and aluminum intake from other parenteral sources. Parenteral aluminum exposure of >4 to 5 mcg/kg/day is associated with CNS and bone toxicity; tissue loading may occur at lower doses (Federal Register, 2002). See manufacturer's labeling.
Patients on parenteral nutrition or chronic therapy should have periodic serum copper and serum zinc levels; alkaline phosphatase, taste acuity, mental depression
Zinc crosses the placenta and can be measured in the cord blood and placenta. Fetal concentrations are regulated by the placenta (de Moraes 2011).
