Insulin pens make it easier than ever to inject on-the-go. And needles (for pens and syringes) have never been shorter or thinner.
The Pen Option
People who take two shots a day or more and seek flexibility and convenience have generally used pens. Pens are simple to use-dial a dose, insert the needle, push the button to inject insulin, and hold. Done! Instead of syringes and vials, you buy pen needles and disposable pens or insulin cartridges.
When you buy either insulin syringes or pen needles, you've got two decisions-the needle length and gauge.
Needle length
Two needle lengths are available for syringes and pens: 5/16” (short) and 1/2” (long). Most people can use the 5/16” needle. Start with this length. If your blood glucose cannot be controlled and you are overweight, you might need the longer 1/2” needle to improve the absorption of insulin. Ask your health care provider which length is best for you.
Needle Gauge
The higher the number the thinner the gauge.
Syringe Size
When you buy insulin syringes, there's one more decision-the size. There are three sizes-3/10cc (holds 30 units), 1/2cc (holds 50 units), and 1cc (holds 100 units). If you take:
- less than 30 units total at one time, use a 3/10 cc syringe
- between 30 and 50 units total at one time, use a 1/2 cc syringe
- between 50 and 100 units total at one time, use a 1 cc syringe
An insulin pen is for you if you:
- vary how much insulin you take based on what you eat
- want and need the flexibility and convenience of carrying your insulin with you
- want a quick, easy, and accurate insulin dose
- don't mind taking extra shots (note: you can't mix two types of insulin in one pen)
- have problems drawing up a dose of insulin due to poor eyesight or shaky hands
- can spend a little more for your insulin (insulin pen vials and disposable pens cost a bit more than insulin vials)
