Insulin Autoinjectors and Unit Scales: 60, 80 and 100-Unit Realities
Published 2026-10-28 · Keywords: insulin autoinjector
Insulin is the therapy that made dose units a global language — and also the therapy where unit scales quietly fragment by region and product. Choosing an insulin autoinjector without first checking your scale against the platform’s increment count is how programs discover, at human-factors stage, that the dial cannot reach the prescribed maximum.
Why unit scales diverge
| Scale | Where it dominates | Device implication |
|---|---|---|
| U-100 (100 units = 1 mL) | Most global insulin | 1 IU = 10 µL; A-60/A-75 style dials map 1:1 |
| 60-unit presentation | Regional prescribing habits, specific analogs | Platforms configured with 60 increments (e.g. WH-DG tirzepatide config adapted) |
| 80-unit presentation | Selected markets and newer analogs | 80-increment configuration (WH-DG insulin degludec config) |
| U-40 / veterinary | Niche and animal health | Requires dedicated dial mapping — not a label change |
The pen does not care which drug it delivers — it cares how many increments the scale needs and what each increment delivers. Matching your insulin’s dosing table to the increment configuration is a documented mapping exercise, done before tooling, not after.
Max-dose checks that catch programs late
A 0–0.60 mL dial window covers a 60-unit maximum at U-100 — but a concentrated analog requiring 80 units at U-100 needs 0.80 mL, which is a different configuration (80 increments). Concentration changes between pipeline generations silently move the required window. Ask your formulation team where the maximum dose will be in five years, then size the increment configuration for that, not for launch only.
How to verify a configuration
Send the full dosing table — every strength, every escalation step, in units. The supplier maps it onto increment configurations in writing: which steps fall on-detent, which land between increments, and the ISO 11608-1 accuracy evidence at the lowest step. Everything else is assumption.
What this does not cover
The devices ship empty and contain no drug; insulin is the dosing-profile example here. Prescribing conventions and clinical scale decisions are your team’s.
