IV Compatibility

Compatible w/ most common diluents (dextrose solns, NS, LR, Ringer's, ½NS, dextrose-saline, dextrose-LR etc)

IV Preparation

Dilute with large volume of compatible fluid to minimize adverse reactions

IV ascorbic acid (Ascor) is supplied as a pharmacy bulk package (PBP)

Intended for dispensing of single doses to multiple patients in a pharmacy admixture program and is restricted to the preparation of admixtures for infusion

Use only in a suitable ISO Class 5 work area such as a laminar flow hood (or an equivalent clean air compounding area)

Open vials are to be used within 4 hr

Prior to administration, the final diluted solution for infusion must be isotonic (undiluted the osmolarity is ~5,900 mOsmol/L)

Calculate the osmolarity of the intended admixture for infusion

Add daily dose directly to an appropriate volume of a suitable infusion solution (eg, 5% Dextrose Injection)

Do not mix with solutions containing elemental compounds that cause reduction (eg, copper)

Final concentration of ascorbic acid admixture solution for infusion: 1-25 mg/mL

Visually inspect for particulate matter and discoloration prior to administration; solution should appear colorless to pale yellow

Immediately use as a slow IV infusion

IV Administration

Avoid rapid infusion

Infusion rate of diluted Ascor solution

  • 5 months-12 months: 1.3 mg/minute
  • 1-11 years: 3.3 mg/minute
