Since insulin cannot be taken orally, it is usually injected subcutaneously (under the skin). Syringe is the most common form of insulin delivery.
What does it involve?
There are many different types of syringe. Your doctor can help guide you in choosing the brand that is right for you. The barrel (the part that holds the liquid) must be large enough to hold a dose. The markings on the barrel must be legible for you. Needle gauge is another factor. The higher the number of the needle gauge, the smaller the needle will be. Some people find that smaller needles cause less pain. Needle length can also be important. If the needle is too long, it may enter the muscle. read more
Some syringes are more expensive than others.
Syringes must be safely disposed of after use. Some states have laws about safe disposal of sharps and other dangerous medical waste.
Some people have a fear of needles or difficulty inserting the needle into the syringe.
If you have vision problems, you may have difficulty measuring doses.
Reusing needles may increase your risk for infection, and used needles may become dull and cause more pain upon injection.
