Diabetes: Giving Yourself an Insulin Shot
What is an Actionset?
If you have type 1 diabetes—or if you have type 2 diabetes and medicines are not controlling your blood sugar—you have to take insulin. If you have gestational diabetes, you may need to take insulin if diet and exercise have not been able to keep your blood sugar levels within your target range.
With little or no insulin, sugar (glucose) in the blood cannot enter your cells to be used for energy. As a result, the sugar in your blood rises above a safe level. When your blood sugar rises past about 180 mg/dL, your kidneys begin to release sugar into the urine, which can make you dehydrated. If you are dehydrated, your kidneys make less urine, which means your body can't get rid of extra sugar. This is when blood sugar levels rise. If you can drink enough fluid to prevent getting dehydrated, you'll be able to release excess sugar in your urine.
Taking insulin can prevent the symptoms of high blood sugar and emergencies such as diabetic ketoacidosis (in type 1 diabetes) and hyperosmolar coma (in type 2 diabetes). Insulin also can help prevent serious and permanent complications from long-term high blood sugar.
Most people use insulin in an injection, or shot. It is given into the fatty tissue just under the skin. It also can be given through an insulin pump, an insulin pen, or a device that sprays the medicine into the skin (jet injector). And now skin patches are available with insulin in them, which can be worn for days. Experts are studying other ways of giving insulin, such as in an implantable pump. But this information is about insulin in syringes.
After you get past the initial anxiety, giving yourself a shot will become a routine part of your day. It's quite easy to learn the basics of drawing the insulin up into a syringe and injecting it. Although never pleasant, the sting of the injection is not bad and does not last long. More than 500,000 people do it every day. You can, too.
The three most important elements of success in giving insulin injections are:
Insulin for injection comes in small glass bottles (vials) and cartridges. Both are sealed with a rubber lid. One bottle or cartridge contains many doses. To remove a dose of insulin from:
Some insulin pens work with premixed insulin cartridges, such as Humulin 70/30, NovoLog Mix 70/30, and Humalog Mix 50/50.
To give an insulin injection, you insert the needle (attached to the syringe) into your skin. Push the plunger to inject the medicine into the fatty tissue just below the skin. Insulin usually is injected into the abdomen, upper arm, or thigh.
Your doctor may have you take two types of insulin at the same time. Because most types of insulin prescribed to be taken at the same time can be mixed together, you most likely will be able to give both doses in the same syringe. But you cannot mix the long-acting insulin glargine (Lantus) or insulin detemir (Levemir) in the same syringe with other types of insulin.

To withdraw a single dose of insulin from a bottle, I need to use a syringe.
To give an injection of insulin, the needle of the syringe is inserted into the skin and the medicine is pushed into the fatty tissue just under the skin.
Normally, insulin is produced by the pancreas. Insulin lets sugar (glucose) in the blood enter body cells, where it is used for energy. It helps the body store extra sugar in muscles, fat, and liver cells. Later, that sugar can be released if it is needed. Without insulin, the body cells cannot use sugar, causing the blood sugar level to rise above what is safe for your body.
You need to take insulin because you have:
Test Your Knowledge
A person whose pancreas produces little or no insulin has to take insulin.
People with type 2 diabetes who are under unusual stress, such as having major surgery, may need to take insulin for a short period of time.
Your health professional or certified diabetes educator (CDE) will help you learn to prepare and give your insulin dose. Here are some simple steps to help you learn this task.
To get ready to give an insulin injection, follow these steps.
Prepare the injection
Your preparation will depend on whether you are giving one type of insulin or mixing two types of insulin.
When you are mixing types of insulin to be given in one syringe, follow these precautions.
If you have poor eyesight, have problems using your hands, or cannot prepare a dose of insulin, you may need someone to prepare your insulin injections ahead of time.
