Understanding your insulin syringe

Measuring your dose
Insulin syringes are used for subcutaneous injections. They are marked in Units on the insulin syringe barrel (see illustration). Insulin syringes facilitate the precise measurement of tiny amounts of liquids which are ideal for medications such as insulin that require small and accurate dosing. Unit marks are also expressed in mL’s and can be interchangeably referenced. A prescriber may write a prescription in Units or in mL’s.
Within the amount of liquid is the prescribed mg dosage of your medication (see mg chart). Milligrams (mg) is not an amount of liquid, but rather the amount of drug that is within. The conversion between units and milligrams varies depending on the concentration of the product being used.
