Syringe and Needle Sizes
Insulin syringes and needles come in various sizes. Which is right for you depends on your age, insulin dosage, and personal comfort level.
Common syringe sizes
- 3/10 cc syringe used for administering 30 units or less
- ½ cc syringe used for doses of 30 to 50 units
- 1 cc syringes used for doses of 50 - 100 units (these are marked in 2-unit measurements)
As a rule, it’s recommended that you use the smallest syringe size that can accommodate your most significant insulin dosage.
Common needle sizes
Syringe needles are measured in both length and gauge (thickness). Standard lengths are 3/16-inch, 5/16-inch, and ½-inch. Gauges usually run from 28 to 31, with the higher number being the thinner needle.
Which one is right for you? That’s a decision to make with your doctor. However, the needle must be long enough to easily reach the subcutaneous fatty tissue beneath the skin without extending into the muscle.
Thinner needles tend to be less painful, but they also take longer to deliver insulin. If you require a large insulin dose, a thicker needle may prove beneficial. Shorter and thinner needles are usually recommended for children to minimize discomfort.
NEVER USE A SYRINGE OR NEEDLE MORE THAN ONCE! ALWAYS DISCARD IMMEDIATELY AFTER USE IN A SHARPS CONTAINER.
Talk to your doctor
Deciding on the proper insulin syringe and needle size is a personal decision that should be made alongside your diabetes physician and based on your specific body type and insulin requirements.
