In the treatment of diabetes, insulin is one of the most effective drugs for controlling blood sugar. Patients with type 1 diabetes usually require lifelong insulin injections, and patients with type 2 diabetes also need insulin injections if oral hypoglycemic drugs are ineffective or contraindicated.
People with type 1 diabetes (insulin resistant) must inject insulin daily. It can be a painful task; choosing the right syringe should be the most critical step. Many people may not know that injecting insulin requires a special syringe. You also have the option to choose a needle gauge.
Insulin must be injected into the subcutaneous region above the intramuscular section. But every individual will have a different thickness of subcutaneous tissue, therefore insulin syringe but with different hypodermic needle size. This article will discuss the different needle sizes you should know before injection.
Insulin Needle Size Guide
It should be noted that there are many types of insulin, and there are specially matched insulin syringes. Insulin syringes must be compared with their matching insulin. Otherwise, it will quickly lead to inaccurate insulin dosage and unstable blood sugar. At the same time, insulin syringes from different manufacturers cannot be used universally.
Does the needle length matter? Yes! Many people living with diabetes have a fear of injections. Learning more about needles may help you get over the hurdle of injecting. Needles come in all different sizes, and there are many options to choose from. Needles are described by length and thickness. Here are some factors you should know:
- Needle length: Needles come in all different lengths. The standard needle is 1/2-inch long. Needles also come in 5/16-inch and 3/16-inch lengths. The 3/16-inch length is often used for children.
- Needle gauge: You can tell a needle's thickness by looking at its gauge (G). The higher the number, the thinner the needle is. For example, 32G needles are thinner than a 27G needle.
Common Insulin Needle Sizes
An essential part of achieving good glycaemic control is accurate dosing. Choose the size of the syringe according to the volume of insulin to be injected, then choose the needle you want.
- 1ml insulin syringe with fixed 29G needle, 0.33mm in thickness and 12.7 mm in length.
- 0.5ml insulin syringe with fixed 29G needle, 0.33mm in thickness and 12.7 mm in length.
- 0.3ml insulin syringe with fixed 29G needle, 0.33mm in thickness and 12.7 mm in length.
Pen needle sizes
Insulin pen needles are available in different sizes, from 4 mm to 12.7 mm (5/32 inch to 1/2 inch) in length. When used up, all the pen needles are disposable and need to be replaced with new refills and needles. An insulin injection pen can be carried with you and is easy to use.
|Length (inch)||Length (mm)|
Generally, the medical community leans towards using shorter needles, such as 4 mm, 5 mm, or 8 mm, but you ultimately need to decide which needle size is right for you. Being prescribed a longer needle can make that initial insulin injection somewhat daunting. Please reach out to your doctor and request a different needle if that is the case. Do not reuse or share your needles with other people.
