Injection training for patients

  • Read the full video transcript

    Randy: Hi, I’m Randy, and I’m going to show you how I take ACTIMMUNE. And believe me, if I can get comfortable with self-injecting, you can, too.

    Super: RANDY, Lives with CGD

    Art Card:

    GET READY

    Randy: When you first start ACTIMMUNE, your doctor or nurse will show you how to inject. If you ever have questions, that’s who to call first. You should also read the Patient/Caregiver Information that came with your ACTIMMUNE. Don’t try to inject until you’ve been trained and told you’re good to go.

    Think of this video as a refresher—a little reminder on how to give an injection. OK? Let’s get started.

    The first thing you do is lay out all your supplies on a clean surface.

    Super: LAY OUT YOUR SUPPLIES

    Randy: I like to take the vial out of the fridge about 15 minutes beforehand, so it has time to get up to room temperature.

    Super: 15 (clock icon)

    Randy: Always look over the vial. If it’s past the expiration date or if it looks cloudy, don’t use it. And don’t ever shake the vial.

    Super: EXAMINE THE VIAL

    • CHECK THE EXPIRATION DATE
    • CHECK FOR CLOUDINESS
    • DO NOT SHAKE THE VIAL
    In addition to your vial of ACTIMMUNE, you’ll need alcohol swabs, alcohol-soaked cotton balls and a syringe and needle. Also a Sharps Container, which you’ll need for disposing of the syringe and needle later.

    Super: (icons for alcohol swabs, syringe/needle, sharps container)

    Art Card: MEASURE

    Randy: Always wash your hands with soap before measuring your dose of ACTIMMUNE.

    Super: ALWAYS WASH YOUR HANDS

    Randy: I take off the red cap from the vial, then I wipe the top with an alcohol swab.

    Randy: I take the syringe out of its package. Leaving on the plastic needle guard, I draw air into the syringe by pulling back on the plunger. I pull it back just to the mark for the dose of ACTIMMUNE my doctor told me to take.

    I take off the needle guard and set it aside for the moment.

    Randy: Holding the vial upright, I carefully stick the needle in through the rubber top.

    Randy: Gently, I push the plunger down all the way so the air goes into the vial.

    Randy: I hold the vial upside down with one hand, and with the other hand, I slowly pull the plunger out to the mark for the dose of ACTIMMUNE my doctor told me to take, drawing the correct amount of medicine into the syringe.

    Randy: I take the needle out and replace the needle guard.

    Art Card: SELECT

    Randy: So I’ve measured my dose and I’ll inject in just a moment, but first I’m going to select an injection site.

    It’s important to rotate the site with every injection, so that the skin has time to heal. The usual injection sites are the thighs…

    Randy: …the belly…

    Randy: …and the upper arms. My doctor told me to look for a place with some fat in it, which minimizes discomfort. If you select the belly, make sure you inject at least 2 inches away from the belly button.

    Super: USUAL INJECTION SITES

    • THIGHS
    • BELLY
    • UPPER ARMS

    (icon for 2 inches away from belly button)

    Art Card: INJECT

    Randy: First, I clean the injection site with an alcohol swab.

    I remove the needle guard, then I hold the syringe, sort of like a pencil.

    Randy: With my other hand, I squeeze the skin to be injected between my fingers.

    Randy: I try to relax, then I put the needle in with a quick, firm motion. It should go in at about a 45-degree angle.

    Super: (icon for 45 degree angle)

    Randy: Now that the needle is in, I pull back on the plunger just a little to see if blood comes into the syringe. There’s no blood in the syringe, so I’m ready to inject. But if I had seen blood, I would have removed the needle from my skin and tried again at another location.

    Randy: Withdraw the needle quickly. Then apply pressure for a few seconds with a cotton ball or gauze.

    Art Card: CLEAN UP

    Randy: I’ve given the injection, but I’m not done until I’ve disposed of everything the right way.

    Super: Visit ACTIMMUNE.com/support to explore all the resources and tools available.

    It’s important to replace the needle guard and toss the needle and syringe in your Sharps Container. And finally, you need to dispose of any unused ACTIMMUNE the way your doctor told you to. Now you’re done. Good job! Randy: Now to help me keep track, I like to record the time and the location of the injection on this injection site calendar.

    Randy: I hope this video helps you become more comfortable with injecting. And if you still have questions, call your doctor.

    IMPORTANT SAFETY INFORMATION

    What is ACTIMMUNE® (Interferon gamma 1-b) used for?

    ACTIMMUNE is part of a drug regimen used to treat Chronic Granulomatous Disease, or CGD. CGD is a genetic disorder, usually diagnosed in childhood, that affects some cells of the immune system and the body’s ability to fight infections effectively. CGD is often treated (though not cured) with antibiotics, antifungals, and ACTIMMUNE.

    ACTIMMUNE is also used to slow the worsening of severe, malignant osteopetrosis (SMO). SMO is a genetic disorder that affects normal bone formation and is usually diagnosed in the first few months after birth.

    When should I not take ACTIMMUNE?

    Don’t use ACTIMMUNE if you are allergic to interferon-gamma, E coli-derived products, or any ingredients contained in the product.

    What warnings should I know about ACTIMMUNE?

    At high doses, ACTIMMUNE can cause (flu-like) symptoms, which may worsen some pre-existing heart conditions.

    ACTIMMUNE may cause decreased mental status, walking disturbances, and dizziness, particularly at very high doses. These symptoms are usually reversible within a few days upon dose reduction or discontinuation of therapy.

    Bone marrow function may be suppressed with ACTIMMUNE, and decreased production of cells important to the body may occur. This effect, which can be severe, is usually reversible when the drug is discontinued or the dose is reduced.

    Taking ACTIMMUNE may cause reversible changes to your liver function, particularly in patients less than 1 year old. Your doctor should monitor your liver function every 3 months, and monthly in children under 1 year.

    In rare cases, ACTIMMUNE can cause severe allergic reactions and/or rash. If you experience a serious reaction to ACTIMMUNE, discontinue it immediately and contact your doctor or seek medical help.

    What should I tell my healthcare provider?

    Be sure to tell your doctor about all the medications you are taking.

    Tell your doctor if you:

    • are pregnant or plan to become pregnant or plan to nurse
    • have a cardiac condition such as irregular heartbeat, heart failure, or decreased blood flow to your heart
    • have a history of seizures or other neurologic disorders
    • have, or have had, reduced bone marrow function. Your doctor will monitor these cells with blood tests at the beginning of therapy and at 3-month intervals on ACTIMMUNE therapy

    What are the side effects of ACTIMMUNE?

    The most common side effects with ACTIMMUNE are “flu-like” symptoms such as fever, headache, chills, muscle pain, or fatigue, which may decrease in severity as treatment continues. Bedtime administration of ACTIMMUNE may help reduce some of these symptoms. Acetaminophen may be helpful in preventing fever and headache.

    What other medications might interact with ACTIMMUNE?

    Some drugs may interact with ACTIMMUNE to potentially increase the risk of damage to your heart or nervous system, such as certain chemotherapy drugs. Tell your doctor about all other medications you are taking.

    Avoid taking ACTIMMUNE at the same time as a vaccination.

    You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.

    The risk information provided here is not comprehensive. To learn more, talk about ACTIMMUNE with your healthcare provider or pharmacist. The FDA-approved product labeling can be found at http://www.ACTIMMUNE.com or 1-866-479-6742.

    Please listen to the Important Safety Information at the end of this video.

    Jeannie: I was extremely nervous giving my son the injection the first time. I was afraid I was going to hurt him; I don’t like needles myself and he had been through so much already. But after the nurse educatior showed us how to do it, and I completed that first injection and now it’s part of our routine.

    Jeannie/ Thaddaeus: Hi, I’m Jeannie, and I’m Thaddaeus and I have been taking ACTIMMUNE for two years and if I can get comfortable with it, you can, too. 

    Super: JEANNIE, Caregiver

    Jeannie: Now that we’ve measured our dose, we have to select an injection site. It’s important to rotate the site with every injection so that the skin has time to recover.

    Jeannie: The usual injection sites are the thighs,…

    Jeannie: …the belly,…

    Jeannie: …and the upper arms. Our doctor told us to look for a place that’s padded by some fat underneath the skin, which helps reduce any pain. If you select the belly, make sure you inject at least 2 inches away from the belly button.

    Jeannie: You have to work together on what works and what doesn’t work. We only do injections in the thighs because he’s not comfortable with the belly or the upper arms.

    Art Card: INJECT

    Jeannie: Now we’re ready to inject ACTIMMUNE. First, I sterilize the injection site with an alcohol swab. Then I remove the needle guard as I hold the syringe just like a pencil.

    Jeannie: With my other hand, I gently squeeze the skin to be injected between my fingers to form a soft fold. I tell Thaddaeus to relax as much as he can…

    Jeannie: …and then I push the needle in with a quick, firm motion at about a 45-degree angle.

    Super: 45 (45 degree angle icon)

    Jeannie: Now that the needle is in, I pull back on the plunger just a little to see if blood comes into the syringe. There’s no blood in the syringe, so I’m ready to inject. But if I had seen blood, I would have removed the needle from his skin and tried again at another location.

    Jeannie: Slowly inject the ACTIMMUNE by gently pushing the plunger until the syringe is empty. This should take just a few seconds.

    Withdraw the needle quickly. Then apply pressure for a few seconds with a cotton ball or gauze. Then put a bandage on, and that’s it.

    Thaddaeus: Now that my injection is done and I’m back in action, we just need to dispose of everything properly.

    Art Card: CLEAN UP

    Jeannie: It’s important to replace the needle guard and toss the needle and syringe in your Sharps Container.

    And finally, dispose of any unused ACTIMMUNE the way your doctor told you to. Now we’re done.

    Super: Visit ACTIMMUNE.com/support to explore all the resources and tools available.

    Jeannie/Thaddaeus: Even after your doctor has taken you through the steps, being nervous about injecting is totally normal.

    But trust me, it gets easier with practice.

    At first I was scared of taking my ACTIMMUNE but now I’ve been practicing and it’s easier.

    Jeannie: I’m extremely proud of the way Thaddaeus handles this. We’ve come a long way, he’s starting to learn how to do each step. He’s got to own this part of managing his disease.

    Jeannie: If you want to review any of these steps again, please refer to the chapters listed on the screen.

    Jeannie: I hope this video helps you become more comfortable.  And if you still have questions, call your doctor.

The 5 steps to inject ACTIMMUNE

  • Get your materials ready

    • Take the ACTIMMUNE vial out of the fridge about 15 minutes prior to injection time so that it can reach room temperature before administration.
    • Look the vial over to make sure it’s not past the expiration date and its contents aren’t discolored.
    • Set the following items onto a clean, flat surface:

    Alcohol swabs

    Syringe, needle, and vial

    Sharps container for disposing of the syringe, needle, and vial

  • Measure your dose

    1

    Wash your hands with soap and water before measuring your dose of ACTIMMUNE.

    2

    Remove the plastic cap from the vial, and then wipe the tip of the rubber stopper with an alcohol swab.

    3

    Take the syringe out of its package. Remove the needle guard and set aside. Then, draw air into the syringe by pulling back on the plunger. Pull it back to the mark for the dose of ACTIMMUNE your doctor prescribed.

    4

    Next, carefully stick the needle in through the rubber top, and push the plunger down all the way so the air goes into the vial.

    5

    Hold the vial upside down with one hand, and with the other hand, slowly pull the plunger out to the mark for the dose of ACTIMMUNE prescribed by your doctor. Each vial is good for only one use.

  • Select the injection site

    Select a site that’s padded by some fat underneath the skin and be sure to rotate the site with every injection, so the skin has time to heal.

    Below are common injection sites you may choose from:

    Right upper arm (back and sides), left upper arm (back and sides)

    Right thigh, left thigh

    Abdomen (right upper and lower, left upper and lower)

    If you select the abdomen, make sure you inject at least 2 inches from the belly button.

  • Inject the medication

    1

    Clean the injection site with an alcohol swab.

    2

    Remove the needle guard while holding the syringe like a pencil.

    3

    With the other hand, gently pinch the skin to be injected in between your fingers. Insert the needle at a 45° angle with a quick, firm motion. This hurts less than pushing the needle in slowly.

    4

    Release the pinch, and slowly inject the ACTIMMUNE by gently pushing the plunger until the syringe is empty. This should only take a few seconds.

    5

    Then quickly pull the needle straight out of the skin. Apply pressure with a cotton ball or gauze.

  • Clean up

    After you’re done with the injection process, place the used needle, syringe, and any unused ACTIMMUNE into the sharps container. If you need help disposing of your sharps container, visit sharpsdisposal.com.

Important: Don’t take ACTIMMUNE until a healthcare professional has given you detailed instructions and shown you how. It’s important to take ACTIMMUNE exactly as your doctor told you to. The most common side effects seen with ACTIMMUNE are “flu-like” symptoms such as fever, headache, chills, muscle pain, or tiredness. These may decrease as treatment continues. See the full Important Safety Information for ACTIMMUNE.

Group 69

TIP: Taking ACTIMMUNE at bedtime may also help with some of these symptoms. Acetaminophen (for example, Tylenol®) may help in preventing fever and headache. See more information about taking ACTIMMUNE.

*An infection is serious if you have to go to the hospital and/or get intravenous (IV) antibiotics.
