Which syringe should be used for administering U-100 insulin?

The syringe specifically designed for administering U-100 insulin is the U-100 syringe. This type of syringe is calibrated to deliver doses based on the concentration of 100 units of insulin per milliliter. Using a U-100 syringe ensures accurate dosing for patients requiring U-100 insulin, which is the standard concentration for most types of insulin available.

In contrast, syringes designed for other concentrations, such as U-50, U-30, or U-10, would not provide the correct dosage if used for U-100 insulin. This is because these syringes would measure insulin in different units per milliliter, leading to potential overdosing or underdosing. Accurate delivery using the correct syringe is crucial in insulin therapy to maintain effective glucose regulation and avoid complications related to insulin mismanagement.
