ACTH 1-39 Reconstitution Calculator
Enter the amount you want to measure. The vial buttons will highlight which vial strengths create cleaner syringe-unit measurements.
What amount do you need?
Type the target amount, then choose mg or mcg. Example: 2mg or 500mcg.
Work the dose out from body weight
Example ACTH 1-39 Titration Schedule
| Use | Dose | Note |
|---|---|---|
| Infantile spasms | 150 U/m²/day IM | 2 wks + taper |
| MS exacerbation | 80–120 U/day IM | 2–3 weeks |
| Other indications | 40–80 U IM | every 24–72 h |
Acthar dosing is units-based (0.25 mg ≈ 25 U). The listed '0.3 mg/kg/day' is untraceable — at 70 kg it would be ~21 mg, roughly 20× the highest label regimen. The repository gel is never given IV; the infusion recipe quoted belongs to the tetracosactide (ACTH 1-24) test.
