Intramuscular (IM) Injection[/h]
What is an Intramuscular Injection?
An intramuscular injection, (illustration
on right) delivers medication deep into
the muscle tissue. This allows the
medication to be quickly absorbed into
the bloodstream.
Intramuscular shots are given at 90
degree angle. Needle for IM injections can
be 22-23 Gauge, 1-1.5 inches in length,
adjusted for thickness of site.
WHERE TO INJECT MUSCLE
Step 1: Setting Up for the Injection
Find a comfortable, well lit working place and inject at the same time each day.
1. Clean your work area.
2. Remove medication from the refrigerator and let it reach room temperature.
3. Make sure it is the medication your doctor prescribed. Check the expiration
date on the vial. Do not use a medication with particles, medication that is
discolored or is expired. Wash your hands. Hand
washing is one of the most important things you
can do to prevent infection.
Assemble supplies:
1. Medication in a vial
2. Disposable syringe and needles, one 18 G
needle to draw up medication then switch
to injection needle (22-23 G; 1-1.5 inch)
3. Alcohol swabs
4. Puncture proof disposal containerStep 2: Selecting and Preparing the

Injection Site
Vastus lateralis muscle in the thigh:
Choose this site if are injecting to yourself, or if a caregiver gives you the
injection. Look at your thigh and divide it horizontally into 3 equal parts. The
injection will go in outer middle third. The thigh is a good place to give yourself
an injection because it is easy to see.
When another person is giving the
injection (picture on the right), the
injection location does not change.
Form a V with your fingers by
separating your first finger from the
other 3 fingers. Place the heel of your
hand on the bone (femur) that ends
before the knee bends and aim the
injection right above the V in the center
of the thigh.
Gluteus Maximus muscle in the buttocks:
You may choose this site only if a caregiver gives you
the injection. To find the correct location for injecting
into the Gluteus maximus muscle, expose the
buttocks and divide (in your mind) each buttock into
four parts. Aim the injection into the upper quarter
of the buttock (X on the diagram), towards the hip
bone portion.
The picture below shows
the position for self-injection.

Step 3: Preparing the Injection Dose
1. Take the cap off the vial. Clean the rubber stopper with one alcohol swab.
Allow to dry.
2. Check the package containing the syringe, if the package has been opened or
damaged, do not use that syringe.
3. Pull the 18 G needle cover straight off the syringe. Then, pull back the
plunger and draw air into the syringe. The amount of air drawn into the
syringe should be the same amount (mL or cc) as the dose that your doctor
prescribed. Do not let the needle touch any surfaces.
4. Keep the vial on your flat working surface and insert the
needle straight down through the center of the rubber
stopper.
Do not put the needle through the rubber stopper more
than once.
5. Push the plunger of the syringe down and push the air
from the syringe into the vial.
6. Keeping the needle in the vial, turn the vial upside
down. Position the needle so the liquid is covering
the tip of the needle.
7. Keeping the vial upside down, slowly pull back on the
plunger to fill the syringe with the medication to the
number (mL or cc) that matches the dose your doctor
ordered.
8. Keeping the needle in the vial, check for air bubbles
in the syringe. If there are air bubbles, gently tap the
syringe with your fingers until the air bubbles rise
to the top of the syringe. Then slowly push the
plunger up to force the air bubbles out of the
syringe without removing the needle from the
bottle.
9. After air bubbles are gone, pull the plunger back
to the number (ml or cc) marking on the syringe
that matches your dose. Remove the 18 G needle
and replace it with the IM needle.
10.Check to make sure that you have the correct
dose in the syringe. It is VERY important that you
use the exact dose prescribed by your doctor.
11.Remove the syringe from the vial but do not lay
it down or let the needle touch anything.
Step 4: Give the Injection
1. Clean the injection site skin with an alcohol swab; let it air dry.
2. Hold the skin around the injection site in the manner described above.
3. Insert the IM needle into the muscle at a 90 degree angle with one quick
and firm motion.
4. After you inserting the needle into the muscle take your hand off the
skin.
5. Gently pull back on the plunger of the syringe to check for blood.
If you see blood in the needle, do not inject the medicine and remove the
needle immediately.
If you do not see any blood in the needle, you can complete the injection
by pushing the medication slowly into the muscle. You may feel some

6. When you finish injecting the full dose of the medication into the muscle,
remove the needle.
7. Gently press an alcohol swab on the injection site. Hold pressure on site
until there is no bleeding. You can place a band aid on injection site if
needed.

Improper disposal of syringes and other sharp objects can pose a health risk

residents a safe needle disposal program through county solid waste divisions
in each county.
