Volume Per Dose

0.050 ml

250 mcg = 0.050 ml

Syringe Units

5.0 units

Draw to the 5.0 mark on 0.5 ml (50 units) syringe

Doses Per Vial

40 doses

at 250 mcg each

Formula

10mg ÷ 2ml = 5.00 mg/ml

250mcg ÷ 5000mcg/ml = 0.0500 ml

0.0500ml ÷ 0.01ml/unit = 5.0 units

Syringe Guide

0.5 ml (50 units) insulin syringe

5.0u

Draw to 5.0 units for 250 mcg

Quick Reference

1 mg= 1,000 mcg

1 ml= 100 units (1ml syringe)

0.01 ml= 1 unit

1 IU (HCG)= 1 mcg (approx)

Reconstitution Best Practices

•Use bacteriostatic water (0.9% benzyl alcohol) as solvent
•Add solvent slowly down the side of the vial
•Swirl gently to dissolve — never shake
•Refrigerate reconstituted solution at 2-8°C
•Use reconstituted solution within 28 days
•Maintain sterile technique throughout
•Use alcohol swabs on vial stoppers before drawing

Avoid

•Using plain sterile water (no preservative for multi-use)
•Directing solvent stream onto lyophilized powder
•Shaking or agitating vigorously
•Leaving reconstituted solution at room temperature
•Freezing reconstituted solutions
•Using contaminated or expired solvents
•Re-using needles between vials
