You will want one that is easy for you to operate. How well you can see to administer your dosage will come into play. Cost, along with how much of that cost, if any, your insurance covers is a component. Don't forget to factor in related supplies and their price. Your occupation and your daily routine have an impact.
Insulin Syringe vs. Insulin Pen
In the United States, insulin needles and syringes are much more common. They cost less money and can be easier to use for those with arthritis or impaired vision. Also, you can use just one syringe to mix multiple types of insulin.
An insulin pen, on the other hand, is often more accurate for small dosages of five units or less. A few mixed-type insulin formulas are available. Pens come as pre-mixed or with a refill cartridge option, along with replaceable insulin pen needles.
Talking with your professional healthcare team about these aspects can help you select the right solution for your situation.

How to Choose Needle Size

As for length, needles that are too short may not reach the subcutaneous fat. Many adults prefer 1/2-inch insulin needles for their treatment. Large children often use the 5/16-inch, with small children using the shortest needle.
