How to prepare and give an insulin injection
Your health professional will help you learn to prepare and give
your insulin dose. Here are some simple steps to help you learn this
task.
Get ready
To get ready to give an insulin injection, follow these
steps.
- Gather your supplies. You will need an
insulin
syringe
, your bottle (or bottles) of insulin, and an alcohol wipe or a
cotton ball dipped in alcohol. Most people keep their supplies in a bag or kit
so they can carry the supplies wherever they go. - Check the
insulin bottle label and contents. When you use an
insulin bottle for the first time, write the date on the bottle. On the 30th
day after opening, throw away the bottle with any remaining insulin. Insulin
may not work as well after 30 days of use.
- Wash your hands with
soap and running water. Dry them thoroughly.
Prepare the injection
Your preparation will depend on whether you are giving one type
of insulin or mixing two types of insulin.
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. See
prefilling insulin syringes.
Prepare the site
Before giving your injection:
- Choose the part of your body to inject. See
the diagram of injection areas
for where to give insulin
injections. If you give your injections in different places on your body each
day (rotate sites), use the same site at the same time of the day. For example,
each day:
- At breakfast, give your insulin into one
of your arms.
- At lunch, give your insulin into one of your
legs.
- At dinner, give your insulin into your abdomen.
- Clean the site. If you use alcohol to clean the
skin before you give the injection, let it dry.
- Relax your muscles
in the area so the injection will be less painful.
Give the injection
Follow these steps for giving an insulin injection.
- Slightly pinch a fold of skin between your
fingers and thumb of one hand.
- Hold the syringe like a pencil close
to the site, keeping your fingers off the plunger. Usually the syringe is at a
90-degree angle to the skin site. If you are a thin adult, you may want to
insert the needle at a 45-degree angle.
- Bend your wrist and quickly
push the needle all the way into the pinched-up area. Then let go of the
pinched-up area.
- Push the plunger of the syringe all the way in so
the insulin goes into the fatty tissue. Wait a few seconds to make sure the
insulin gets into the tissues.
- Take the needle out at the same
angle that you inserted it. If you bleed a little, apply pressure over the
injection site with your finger, a cotton ball, or piece of gauze. Do not rub
the area. Check your blood sugar more frequently on the days when bleeding
occurs.
- Replace the cover over the needle. Although syringe
manufacturers do not recommend it, some people reuse their syringes until the
needle becomes dull or bent. If you plan to reuse your syringe, see
precautions when reusing syringes.

Cleanup and storage
After giving your injection, be sure to:
- Store your insulin properly so that
each dose from the bottle will work effectively.
- Dispose of your
used syringe. Do not throw your used syringe and needle into a household
wastebasket or trash can. Ask your pharmacist about the safe disposal of
sharps. Some pharmacies provide free containers and will dispose of them for
you. You can dispose of them yourself in a metal container, such as a coffee
can, that has a lid that screws on or that you tape down tightly. Or you can
buy special containers for disposing of used needles and syringes. You can also
buy a small needle clipper device that breaks the needle off the syringe and
stores it safely for disposal. Talk with your local trash disposal agency or
your health professional about how to get rid of the container.
Other tips for success and safety
- Do not mix other medication with insulin
without your doctor's instruction; some types of insulin cannot be mixed
together. See
precautions when mixing insulin for more
information.
- Never share syringes. Syringes should never be shared
with another person because of the risk of getting diseases that can be
transferred through blood, such as acquired immunodeficiency syndrome (AIDS) or
infection of the liver (hepatitis).
Test Your Knowledge
Practice
Review the slideshow of
steps for
preparing a single dose of insulin
. Give a copy of the steps to a health
professional or someone else and have the person watch you prepare your dose of
insulin. Ask the person to tell you how well you did. Repeat this process as
many times as you need to.
Use the same process for preparing a mixed dose of insulin, if
you need to take two types of insulin in one injection. Review the slideshow of
steps for
preparing a mixed dose of insulin
.
Practice injecting air or water into an orange until you feel
comfortable with the steps for giving insulin. Then do the steps in front of a
health professional and ask him or her how you did. Practice more if you need
to. If you feel that you can do the task well, give yourself a dose of insulin
while a health professional watches.
Determine whether the following statements are true. Review the
slideshows of
steps for
preparing a single dose of insulin
and
steps for
preparing a mixed dose of insulin
before answering these
questions.
The first step in preparing insulin from a bottle is
to roll the bottle gently between your hands.
- True
- False
When you are preparing a cloudy and a clear insulin to
give a mixed dose, which do you put into the syringe first?
- Cloudy insulin
