Discharge Instructions: Giving Yourself an Intramuscular (IM) Injection in the Upper Arm

Name of your medicine: ___________________________

Amount per injection: ____________________________

Times per day: _______________________________

Before you start

• Use the upper arm site only if other larger sites can't be used.

• Don’t use the upper arm site if you are very thin or have little to no muscle in your upper arm.

Step 1. Getting ready

• Wash your hands well with soap and clean, running water or use alcohol-based hand sanitizer before and after all IM injections.

• Prepare your medicine as you were shown by your healthcare provider.

Step 2. Finding an injection site

The site will be on the outer side of your upper arm. Imagine the shape of an upside-down triangle here. You will find a site in the center of this area. To find an injection site:

• Touch the bone at the top of your upper arm. It's where your arm meets your shoulder. This is the top side of the upside-down triangle.

• Move your hand about 3 to 4 inches down the outer side of your upper arm. The bottom point of the triangle is here, at about the level of your armpit.

• The injection site is in the center of this triangle. It's about 1 to 2 inches below the bone at the top of your upper arm.

Step 3. Injecting the medicine

Prepare the site as you were shown by your healthcare provider. See the general instruction sheet on giving yourself an IM injection. If you did not get this sheet, ask for one. Then:

• Stretch your skin tight.

• Hold the syringe like a pencil. Insert the needle straight into your skin and into the muscle at a 90-degree angle.

• You may be told by your healthcare provider to pull back slightly on the plunger. This is to make sure you did not hit a blood vessel with the needle. If blood appears in the syringe, remove the needle and don't inject the medicine. It might go into the bloodstream and not the muscle. Dispose of the needle and syringe in a sharps container and repeat the process in a different spot on your upper arm.

• To inject the medicine, push down on the plunger at a steady rate.

• Give no more than 2 mL of medicine in this site. If the prescribed dose is more than 2 mL, choose a different site to inject more medicine.

Step 4. Removing the needle

• Remove the needle and syringe outward and away from your body.

• Let go of the skin.

Step 5. After the injection

• Press a gauze pad onto the site.

• Hold the pad tightly for a minute.

• Check the area for redness, bleeding, or bruising.

• Apply a bandage to the site, if needed.

• Put the needle and syringe in a sharps container.

• Dispose of the other materials as you were shown by your healthcare provider.

• Wash your hands well.

Medicine that comes in a container for a single dose should be used only 1 time. If you use the container a second time, it may have germs in it that can cause infections. These infections usually affect the skin and soft tissues. But some infections can affect the brain, spinal cord, or heart. Sharing another person's used needles or medicines can cause other infections, such as hepatitis B, hepatitis C, and HIV.

Follow-up care

Follow up with your healthcare provider, or as advised.
