U-500 insulid is a highly concentead formulation contining 500 units of insulin per milliter (U / ml).

U- 100 Insulin

Standard U-100 insulin is the mogt common formulation, used for the majority of patients on insulin terary. It contens 100 units per milliter and is avavavable in rapid- acting analogues (lispro, aspart, glulisine), shortting regular insulin, mediate- acting NPH, and long-acting analogues (glargine, detemir, degludedek).

U- 200 Insulin

U-200 insulin formulations, such as insulid degludec U-200 (Tresiba), contain 200 units per millititer. These are primarily long- acting basal insulins designed for once- daily dosing. U-200 degludec provides a flat and stable time- action profile lasting over 42 hours, alloing for flexible administration timing.

Dosing Errors and Risk Mitigation

Injektion Site and Technique

Due to smaller involtion volume (e.g., 0.4 mL for a 200-unit dose versus 2.0 mL for U-100), U-500 can bee revened with less tissue trauma.
