How the math works
- Dose each week: the starting dose plus one step for every full block of weeks that has passed, never above the top dose.
- Syringe mark: the mcg in the vial divided by the bac water gives mcg per mL. The dose divided by that gives mL, and mL times 100 gives units on a U-100 syringe.
- Total for the plan: each week's dose times doses a week, added up across every week.
- Vials needed: total mg divided by the vial size, rounded up.
Worked examples
A sample plan: start at 2 mg once a week, go up 2 mg every 4 weeks to a top dose of 8 mg, for 16 weeks, from a 20 mg vial mixed with 2 mL of bac water (10 mg per mL).
| Weeks | Dose | Draw to (U-100) |
|---|---|---|
| 1 to 4 | 2 mg | 20 units |
| 5 to 8 | 4 mg | 40 units |
| 9 to 12 | 6 mg | 60 units |
| 13 to 16 | 8 mg | 80 units |
| Total | 80 mg | 4 vials of 20 mg |
Questions
What is a titration schedule?
A plan where the dose starts low and steps up at set points. Writing it out week by week shows what you draw at each step and how much you need to buy.
Does this calculator suggest a dose?
No. It only does the arithmetic on numbers you enter. The starting dose, the steps and the top dose should come from your clinician.
Why might a step show more units than my syringe holds?
Larger doses need more liquid. Use a bigger syringe, split the draw, or mix the vial with less water so each unit holds more.
Can the dose stay the same?
Yes. Set the step to 0 and the schedule stays flat. The vial supply calculator is simpler for a flat plan.
