Worked example: 150 mcg

  1. Convert the vial amount to mcg: 2 mg × 1,000 = 2,000 mcg
  2. Concentration: 2,000 mcg ÷ 1.5 mL = 1,333.33 mcg/mL (1.33333 mg/mL)
  3. Volume to draw: 150 mcg ÷ 1,333.33 mcg/mL = 0.1125 mL
  4. Units to draw: 0.1125 mL × 100 units/mL = 11.3 units
  5. Amount in each unit: 1,333.33 mcg/mL ÷ 100 units/mL = 13.33 mcg per unit (0.01333 mg)
  6. Doses in the vial: 2,000 mcg ÷ 150 mcg = 13 full doses

Draw 11.3 units on a U-100 syringe, between the 10- and 12-unit marks, closer to 12. The same 150 mcg dose is 7.5 units with 1 mL of water and 15 units with 2 mL of water, compared with 11.3 units with 1.5 mL.

Frequently asked questions

What is the concentration of a 2 mg vial with 1.5 mL of water?

A 2 mg vial mixed with 1.5 mL of water holds 1,333.33 mcg per mL. Each unit on a U-100 syringe holds 13.33 mcg.

How many units is 150 mcg with a 2 mg vial and 1.5 mL of water?

It is 11.3 units on a U-100 syringe, which is 0.1125 mL of the mixed liquid.

What is the smallest dose you can measure well with a 2 mg vial and 1.5 mL of water?

About 26.67 mcg, which fills 2 units on a U-100 syringe. Smaller amounts are hard to read; a vial mixed with more water spreads them over more units.

What is the largest dose that fits a 1 mL syringe with a 2 mg vial and 1.5 mL of water?

1,333.33 mcg, which fills all 100 units of a 1 mL U-100 syringe. Larger doses need more than one draw or a stronger mix.

How many doses does a 2 mg vial with 1.5 mL of water give?

Divide 2,000 mcg by your dose and round down: 13 full doses of 150 mcg, or 10 of 200 mcg.
