Infants and Children weighing 10 to 40 kg: IV: 1 to 2 mcg/kg/day (ASPEN [Corkins 2015]; ASPEN [Mirtallo 2004]); maximum daily dose: 100 mcg/day (ASPEN [Vanek 2012]; ASPEN [Vanek 2015]).
Children and Adolescents weighing >40 kg: IV: 2 mcg/kg/day; maximum daily dose: 100 mcg/day (ASPEN [Corkins 2015]; ASPEN [Vanek 2012]); ASPEN [Vanek 2015]).

Oral: Bariatric surgery: Tablet, extended release: Some institutions may have specific protocols that conflict with these recommendations; refer to institutional protocols as appropriate. ER tablets should be swallowed whole. Do not break, crush, or chew. IR tablet, capsule, oral solution, and injectable formulations are available. If safety and efficacy can be effectively monitored, no change in formulation or administration is required after bariatric surgery. Bariatric vitamin supplementation is recommended on a lifelong basis after surgery; may consider integration of daily selenium regimen into the bariatric vitamin regimen.
Dietary adequate intake (AI): Note: Breast milk, formula, and food should be the only sources of selenium for infants (NIH 2019).
1 to 6 months: 15 mcg/day.
7 to 12 months: 20 mcg/day.

Prior to use, store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).
Baloxavir Marboxil: Polyvalent Cation Containing Products may decrease the serum concentration of Baloxavir Marboxil. Avoid combination
Bictegravir: Polyvalent Cation Containing Products may decrease the serum concentration of Bictegravir. Management: Administer bictegravir under fasting conditions at least 2 hours before or 6 hours after polyvalent cation containing products. Coadministration of bictegravir with or 2 hours after most polyvalent cation products is not recommended. Consider therapy modification
Bisphosphonate Derivatives: Polyvalent Cation Containing Products may decrease the serum concentration of Bisphosphonate Derivatives. Management: Avoid administration of oral medications containing polyvalent cations within: 2 hours before or after tiludronate/clodronate/etidronate; 60 minutes after oral ibandronate; or 30 minutes after alendronate/risedronate. Exceptions: Pamidronate; Zoledronic Acid. Consider therapy modification
Deferiprone: Polyvalent Cation Containing Products may decrease the serum concentration of Deferiprone. Management: Separate administration of deferiprone and oral medications or supplements that contain polyvalent cations by at least 4 hours. Consider therapy modification
Dolutegravir: Selenium may decrease the serum concentration of Dolutegravir. Management: Administer dolutegravir at least 2 hours before or 6 hours after oral selenium. Administer the dolutegravir/rilpivirine combination product at least 4 hours before or 6 hours after oral selenium. Consider therapy modification
Eltrombopag: Polyvalent Cation Containing Products may decrease the serum concentration of Eltrombopag. Management: Administer eltrombopag at least 2 hours before or 4 hours after oral administration of any polyvalent cation containing product. Consider therapy modification
Elvitegravir: Polyvalent Cation Containing Products may decrease the serum concentration of Elvitegravir. Management: Administer elvitegravir 2 hours before or 6 hours after the administration of polyvalent cation containing products. Consider therapy modification
PenicillAMINE: Polyvalent Cation Containing Products may decrease the serum concentration of PenicillAMINE. Management: Separate the administration of penicillamine and oral polyvalent cation containing products by at least 1 hour. Consider therapy modification
Raltegravir: Polyvalent Cation Containing Products may decrease the serum concentration of Raltegravir. Management: Administer raltegravir 2 hours before or 6 hours after administration of the polyvalent cations. Dose separation may not adequately minimize the significance of this interaction. 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.
• Gastrointestinal dysfunction: Use with caution in patients with GI impairment.
• Renal impairment: Use with caution in patients with renal impairment.
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.
Plasma selenium concentration for patients receiving long-term PN (every 3 to 6 months; some patients (ie, HSCT) may require more frequent monitoring) (ASPEN Pediatric Nutrition Support Core Curriculum [Corkins 2010])
Adverse events were seen with high doses in animal studies. Selenium is found in the placenta and cord blood. Teratogenic effects have not been observed with nontoxic doses in humans (IOM, 2000).
