Guide to Choosing Your Pen Needle
Selecting the best needle for your particular circumstances always starts with a discussion with your diabetes healthcare professional. Here are some factors to consider when making your choice:
Needle Length and Gauge
Clickfine pen needles come in three lengths, measured in millimeters (mm), and two diameters, measured in gauges (G). The larger the gauge number, the thinner the needle. Clickfine comes in 3 sizes for custom fit:

Your Specific Injection Technique
Your injection technique affects which needle length is best for you. Depending on the angle you use for injecting your medication, you may benefit from a shorter or longer needle. See how injection angle guides your needle choice.
Your Physical Makeup
Your build and the amount of body fat (subcutaneous tissue) on your body are important to consider when choosing the right pen needle length for you. Your Body Mass Index (BMI) is one way to calculate your amount of body fat. Visit the CDC (Center for Disease Control and Prevention) to calculate your BMI. Children and young adults have additional considerations. Review our pen needle Length Selection Chart.
Dexterity Issues
If you have arthritis, other manual dexterity issues, or vision impairment, you may find simple click-on pen needle attachment easier than the traditional screw-on attachment.
Dose Size
Larger diameter pen needles help large doses of medicine flow more quickly through the needle and require less manual strength.
Be Prepared for a Low
If you inject insulin, you are likely to experience hypoglycemia (low blood sugar). Correcting hypoglycemia immediately is important. So, carry glucose tablets with you wherever you go to be prepared to correct a low. Glucose tablets act quickly, are pre-measured, have no fat or caffeine, and are the preferred way to correct lows according to the American Diabetes Association.
