Insulin Needles: Frequently Asked Questions
Pen needles attach to an insulin pen and are used once. Insulin syringes have a fixed needle and are used to draw insulin from a vial. Your doctor or diabetes educator will advise which you need.
Length is measured in millimetres (for example 4mm or 8mm). Gauge (G) is the thickness: the higher the number, the finer the needle, so 32G is finer than 29G.
Most BD and NovoFine pen needles fit most common insulin pens, but always check the compatibility listed on the needle packaging or your pen’s instructions. Ask our pharmacists if you’re unsure.
No. Pen needles and syringes are designed for single use. Use a new needle for each injection and dispose of it in a sharps container.
