Insulin Syringe Converter

Why is this helpful?

Sometimes a vet will prescribe U-40 insulin (like ProZinc), but you may only have access to U-100 syringes. Using the wrong syringe without proper conversion can lead to a fatal overdose. This tool helps you find the exact mark on a U-100 syringe for your prescribed U-40 dose.

Convert U-40 prescribed units to U-100 syringe marks.

Disclaimer: CRITICAL: Always consult your vet before altering injection equipment. Incorrect dosing can be fatal.
