Bronchogen Dosing & Reconstitution Chart
How many insulin-syringe units to draw for Bronchogen, based on how much bacteriostatic water you add to a 5 mg vial. Every number below is on a U-100 (100 units = 1 mL) syringe and matches our calculator.

| Water added | Concentration | 1000 mcg dose | 2000 mcg dose | 3000 mcg dose | 4000 mcg dose |
|---|---|---|---|---|---|
| 1 mL | 5 mg/mL | 20 u | 40 u | 60 u | 80 u |
| 2 mL | 2.5 mg/mL | 40 u | 80 u | 120 u | 160 u |
| 3 mL | 1.667 mg/mL | 60 u | 120 u | 180 u | 240 u |
| 5 mL | 1 mg/mL | 100 u | 200 u | 300 u | 400 u |
Cells show units to draw on a U-100 insulin syringe. Highlighted cells exceed one full 1 mL (100-unit) syringe — add more water, split the dose, or use a larger syringe.
Calculate your exact Bronchogen dose
Pre-filled with Bronchogen’s commonly cited vial and dose. Change any field to match your vial — it shows the exact units, concentration, and doses per vial.
Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 2 doses of 2000 mcg. For each dose, draw 80 units into a 100-unit insulin syringe.
Bronchogen dosing FAQ
How many units of Bronchogen should I draw?
Reconstituting a 5 mg vial of Bronchogen with 2 mL of bacteriostatic water gives 2.5 mg/mL. A 2000 mcg dose is about 80 units on a U-100 insulin syringe, roughly 2 doses per vial. This is a commonly cited example for context, not medical advice.
How much bacteriostatic water do I add to Bronchogen?
There is no single correct amount. More water makes each dose a larger, easier-to-measure volume; less water makes it more concentrated. The chart above shows the units for 1–5 mL — 2 mL is a common choice for a 5 mg vial.
How many doses are in a 5 mg Bronchogen vial?
At a 2000 mcg dose, a 5 mg vial holds about 2 doses. Larger doses mean fewer doses per vial, and the amount of water you add does not change this.
