FAQs
Should I choose the 6 mm or the 8 mm needle?
Follow your clinician's guidance on needle length. Current diabetes injection guidance generally favors shorter needles for most adults because they reduce the chance of injecting into muscle. Some people with more subcutaneous tissue, or who have been trained on 8 mm, may prefer the longer option.
Why use a 1 mL syringe if my dose is small?
You generally should not. For doses under 30 units, a 0.3 mL syringe has more widely spaced markings that are easier to read accurately, and under 50 units, a 0.5 mL syringe does the same. Use the 1 mL size when your typical dose is above 50 units.
Does a 31 gauge needle hurt less?
Many users find thinner needles more comfortable, and 31G is among the finest insulin syringe needles available. Comfort also depends on injection technique, needle length, site rotation, and using a fresh needle every time, since tri-bevel tips are designed for a single, sharp entry rather than repeated use.
Can these syringes be used with U-200 or U-500 insulin?
No. These syringes are marked for U-100 insulin only. Using them with a more concentrated insulin would make the unit markings wrong and could cause a serious dosing error. Concentrated insulins require the specific device or syringe their labeling specifies, so always check the insulin label first. When in doubt, ask your pharmacist.
How should you dispose of used insulin syringes at home?
Place each used syringe, needle attached, into an FDA-cleared sharps container or a heavy-duty plastic container with a tight lid, as local rules allow. Never throw loose syringes in household trash or recycling. Many communities offer drop-off sites or mail-back programs for full containers. Keep containers out of reach of children.
