  • How do I prepare and give an injection with ENBREL® Multiple-use Vial?

    A multiple-use vial contains 25 mg of ENBREL®.

    STEP 1: Setting up for an Injection

    • Select a clean, well-lit, flat work surface, such as a table.
    • Take the ENBREL® dose tray out of the refrigerator and place it on your flat work surface.
    • Check the expiration date on the dose tray. If the expiration date has passed, do not use the dose tray. Also check to make sure the dose tray has seven items as pictured below:
      • One prefilled diluent syringe containing 1 mL of diluent (liquid) with attached adapter and twist-off cap
      • One plunger
      • One ENBREL® vial
      • One 27-gauge ½ inch needle in hard plastic cover
      • One vial adapter
      • Two alcohol swabs

    If the expiration date has passed, the seven items are not included in the dose tray or if any item looks damaged, contact your pharmacist or call 1-888-4ENBREL (1-888-436-2735) for assistance.

    • Wash your hands with soap and warm water.
    • Peel the paper seal off the dose tray and remove all items.
    • Inspect the volume of diluent in the syringe with the twist-off cap pointing down. Use the unit markings on the side of the syringe to make sure there is at least 1 mL of liquid in the syringe. If the level of liquid is below the 1 mL mark, do not use. Call 1-888-4ENBREL (1-888-436-2735) for assistance.

    STEP 2: Preparing the ENBREL® Solution

    There are two methods for preparing the ENBREL® solution. For some children, one vial of ENBREL® solution can be used for more than one dose. The free-hand method should be used for children on ENBREL® who are using one vial of ENBREL® solution for more than one dose. You should not use the vial adapter method if you will be using the vial more than once. Ask your healthcare provider if you have questions about which method to use.

    • The Vial Adapter Method

    Adult patients and larger children on ENBREL® may use the vial adapter device to assist with mixing the powder with the liquid and withdrawing ENBREL®, and then use a 27-gauge needle to inject the dose. This method should not be used for children using multiple doses from the same vial of ENBREL®. The instructions for using the vial adapter method are in STEP 2A.

    • The Free-Hand Method

    In the free-hand method, a 25-gauge needle is used to assist with mixing the powder with the liquid and withdrawing ENBREL®, and a 27-gauge needle is used to inject the dose. Obtain 25-gauge needles from your healthcare provider. Instructions for using the free-hand method are in STEP 2B.

    The instructions for preparing additional doses from the same vial of ENBREL® solution are in STEP 3. For each additional dose, you will need two new needles (one 25-gauge needle to withdraw the solution and one 27-gauge needle for injection) and one new empty syringe (1 mL). NEVER REUSE A SYRINGE OR NEEDLE.

    If you are using the vial of ENBREL® for more than one dose, you should write the date you mixed the powder and liquid in the area marked “Mixing Date:” on the sticker supplied with these instructions, and attach the sticker to the ENBREL® vial.

    After you have withdrawn the dose of ENBREL® that you need, store the ENBREL® vial (in the dose tray) in the refrigerator at 36° to 46°F (2° to 8°C) as soon as possible, but always within 4 hours of mixing the solution.

    The ENBREL® solution must be used within 14 days of the mixing date. You should discard the ENBREL® vial and any remaining solution if it is not used within 14 days. Do not mix any remaining liquid in one vial of ENBREL® solution with another.

    STEP 2A: Vial Adapter Method

    • Remove the pink plastic cap from the ENBREL® vial. Do not remove the gray stopper or silver metal ring around the top of the ENBREL® vial.
    • Place the ENBREL® vial on your flat work surface or turn your dose tray upside down and place your ENBREL® vial in the round space marked “V”. Use one alcohol swab to clean the gray stopper on the ENBREL® vial. Do not touch the gray stopper with your hands.
    • Open the wrapper that contains the 27-gauge needle by peeling apart the tabs and set the needle aside for later use.
    • Open the wrapper that contains the vial adapter by peeling apart the tabs and set the vial adapter aside for later use. Do not touch the vial adapter’s twist-on end or the spike inside.
    • Slide the plunger into the flange end of the syringe.
    • Attach the plunger to the gray rubber stopper in the syringe by turning the plunger clockwise until a slight resistance is felt.
    • Remove the twist-off cap from the prefilled diluent syringe by turning counter-clockwise. Do not bump or touch the plunger. Doing so could cause the liquid to leak out. You may see a drop of liquid when removing the cap. This is normal. Place the cap on your flat work surface. Do not touch the syringe tip.
    • Once the twist-off cap is removed, pick up the vial adapter with your free hand. Twist the vial adapter onto the syringe until a slight resistance is felt. Do not over-tighten.
    • Hold the ENBREL® vial upright on your flat work surface. Grasp the sides of the vial adapter and place it over the top of the ENBREL® vial. Do not bump or touch the plunger. Doing so could cause the liquid to leak out. Insert the vial adapter into the gray stopper on the ENBREL® vial. The plastic spike inside the vial adapter should puncture the gray stopper. The vial adapter should fit snugly.
    • Hold the ENBREL® vial upright on your flat work surface and push the plunger down until all the liquid from the syringe is in the ENBREL® vial. You may see foaming (bubbles) in the vial. This is normal.
    • Gently swirl the ENBREL® vial in a circular motion to dissolve the powder. If you used the dose tray to hold your ENBREL® vial, take the vial (with the vial adapter and syringe still attached) out of the dose tray, and gently swirl the vial in a circular motion to dissolve the powder.DO NOT SHAKE. Wait until all the powder dissolves (usually less than 10 minutes). The solution should be clear and colorless. After the powder has completely dissolved, foam (bubbles) may still be present. This is normal. Do not inject the solution if it is discolored, contains lumps, flakes, or particles. If all the powder in the ENBREL® vial is not dissolved or there are particles present after 10 minutes, call 1-888-4ENBREL (1-888-436-2735) for assistance.
    • Turn the ENBREL® vial upside down. Hold the syringe at eye level and slowly pull the plunger down to the unit markings on the side of the syringe that correspond with your/your child’s dose. For adult patients, remove the entire volume (1 mL), unless otherwise instructed by your doctor. Be careful not to pull the plunger completely out of the syringe. Some white foam may remain in the ENBREL® vial. This is normal.
    • Check for air bubbles in the syringe. Gently tap the syringe to make any air bubbles rise to the top of the syringe. Slowly push the plunger up to remove the air bubbles. If you push solution back into the vial, slowly pull back on the plunger to again draw the correct amount of solution back into the syringe.
    • Remove the syringe from the vial adapter, by holding the vial adapter with one hand and turning the syringe counterclockwise with your other hand. Do not touch or bump the plunger. Place the ENBREL® vial with the vial adapter on your flat work surface.
    • Continue to hold the barrel of the syringe. With your free hand, twist the 27-gauge needle onto the tip of the syringe until it fits snugly. Do not remove the needle cover from the syringe. Place the syringe on your flat work surface until you are ready to inject ENBREL®.

    GO TO STEP 4: CHOOSING AND PREPARING AN INJECTION SITE.

    STEP 2B: Free-Hand Method

    If you are preparing a dose from an ENBREL® vial that was previously used, go to STEP 3: Preparing Additional Doses from a Single ENBREL® Vial.

    • Remove the pink plastic cap from the ENBREL® vial. Do not remove the gray stopper or silver metal ring around the top of the ENBREL® vial. Write the date you mix the powder and solution on the supplied “Mixing Date:” sticker and attach it to the ENBREL® vial.
    • Place the ENBREL® vial on your flat work surface. Use one alcohol swab to clean the gray stopper on the ENBREL® vial. Do not touch the gray stopper with your hands.
    • Open the wrapper that contains the 25-gauge needle by peeling apart the tabs and set the needle aside for later use. The 25-gauge needle will be used to mix the liquid with the powder and for withdrawing ENBREL® from the vial.
    • Slide the plunger into the flange end of the syringe.
    • Attach the plunger to the gray rubber stopper in the syringe by turning the plunger clockwise until a slight resistance is felt.
    • Remove the twist-off cap from the prefilled diluent syringe by turning counter-clockwise. Do not touch or bump the plunger. Doing so could cause the liquid to leak out. You may see a drop of liquid when removing the cap. This is normal. Place the cap on your flat work surface. Do not touch the syringe tip.
    • Continue to hold the barrel of the syringe. With your free hand, twist the 25-gauge needle onto the tip of the syringe until it fits snugly. Place the syringe on your flat work surface.
    • Open the wrapper that contains the 27-gauge needle by peeling apart the tabs and set the needle aside for later use. The 27-gauge needle will be used to inject the dose.
    • Pick up the syringe from your flat work surface. Hold the barrel of the syringe with one hand, and pull the needle cover straight off. Do not touch the needle or allow it to touch any surface. Do not touch or bump the plunger. Doing so could cause the liquid to leak out.
    • Place the needle cover (open side up) in the round space marked “N” in the ENBREL® dose tray.
    • Place the ENBREL® vial on your flat work surface. Hold the syringe with the needle facing up, and gently pull back on the plunger to pull a small amount of air into the syringe. Then, insert the needle straight down through the center ring of the gray stopper (see illustrations). You should feel a slight resistance and then a “pop” as the needle goes through the center of the stopper. Look for the needle tip inside the open stopper window. If the needle is not correctly lined up with the center of the stopper, you will feel constant resistance as it goes through the stopper and no “pop”. The needle may enter at an angle and bend, break or prevent you from adding diluent into the ENBREL® vial.
    • Push the plunger down VERY SLOWLY until all liquid from the syringe is in the ENBREL® vial. Adding the liquid too fast will cause foaming (bubbles).
    • Leave the syringe in place. Gently swirl the ENBREL® vial in a circular motion to dissolve the powder.DO NOT SHAKE. Wait until all the powder dissolves (usually less than 10 minutes). The solution should be clear and colorless. After the powder has completely dissolved, foam (bubbles) may still be present. This is normal. Do not inject the solution if it is discolored, contains lumps, flakes, or particles. If all the powder in the ENBREL® vial is not dissolved or there are particles present after 10 minutes, call 1-888-4ENBREL (1-888-436-2735) for assistance.
    • With the needle in the ENBREL® vial, turn the vial upside down. Hold the syringe at eye level and slowly pull the plunger down to the unit markings on the side of the syringe that correspond with the correct dose. Make sure to keep the tip of the needle in the solution. Some white foam may remain in the ENBREL® vial. This is normal.
    • With the needle still inserted in the ENBREL® vial, check for air bubbles in the syringe. Gently tap the syringe to make any air bubbles rise to the top of the syringe. Slowly push the plunger up to remove the air bubbles. If you push solution back into the vial, slowly pull back on the plunger to draw the correct amount of solution back into the syringe.
    • Remove the syringe and needle from the ENBREL® vial. Keep the needle attached to the syringe and insert the 25-gauge needle straight down into the needle cover in the ENBREL® dose tray.You should hear a “snap” when the needle is secure in the needle cover. Once the needle is secure in the needle cover, untwist the 25-gauge needle from the syringe and dispose of the needle in your SHARPS container.
    • Twist the 27-gauge needle onto the syringe until it fits snugly. Do not remove the needle cover from the syringe. Place the syringe on your flat work surface until you are ready to inject ENBREL®.
    • If there is enough solution left in the ENBREL® vial for another dose, write the date you mixed the powder and liquid in the area marked “Mixing Date:” on the sticker supplied with these instructions, and attach the sticker to the ENBREL® vial. Refrigerate the ENBREL® vial (in the dose tray) after use. Prepare additional doses from the ENBREL® vial as described in STEP 3. Otherwise, discard the ENBREL® vial and any remaining solution.

    GO TO STEP 4: CHOOSING AND PREPARING AN INJECTION SITE.

    STEP 3: Preparing Additional Doses from a Single ENBREL® Vial

    • Select a clean, well-lit, flat work surface, such as a table.
    • The needles and syringes supplied with ENBREL® should not be reused. You will need new ones for each additional dose. Your healthcare provider will tell you what type of syringes (1 mL) and needles (25- and 27-gauge) to use. Alcohol swabs are available at the drug store. Place the sterile syringe with a 25-gauge needle (for withdrawing ENBREL®), a 27-gauge needle (for injecting ENBREL®) and two alcohol swabs on your flat work surface.
    • Take the vial of ENBREL® solution that is stored in the dose tray out of the refrigerator and place it on your flat work surface.
    • Check the mixing date you wrote on the sticker on the ENBREL® vial. Discard the ENBREL® vial if more than 14 days have passed since the ENBREL® solution was mixed.
    • Wash your hands with soap and warm water.
    • Use one alcohol swab to clean the gray stopper on the ENBREL® vial. Do not touch the stopper with your hands.
    • If the syringe and the 25-gauge needle are not pre-assembled, assemble them as instructed by your healthcare provider.
    • Open the wrapper that contains the 27-gauge needle by peeling apart the tabs and set the needle aside for later use. The 27-gauge needle will be used to inject the dose of ENBREL®.
    • Hold the syringe and pull the needle cover straight off. Do not touch the needle or allow it to touch any surface. Place the needle cover (open side up) in the round space marked “N” in the ENBREL® dose tray.
    • Place the ENBREL® vial on your flat work surface. Hold the syringe with the needle facing up, and gently pull back the plunger to pull a small amount of air into the syringe. Then, insert the 25-gauge needle straight down through the center ring of the gray stopper. You should feel a slight resistance and then a “pop” as the needle goes through the center of the stopper. Look for the needle tip inside the open stopper window. If the needle is not correctly lined up with the center of the stopper, you will feel constant resistance as it goes through the stopper and no “pop”. The needle may enter at an angle and bend, break, or prevent proper withdrawal of ENBREL® solution from the vial.
    • Keep the needle in the ENBREL® vial and turn the vial upside down. Hold the syringe at eye level, and slowly pull the plunger down to the unit markings on the syringe that correspond to your child’s dose. As the amount of solution in the ENBREL® vial drops, you may need to pull the needle back just enough to keep the tip of the needle in the solution.
    • With the needle still inserted in the ENBREL® vial, check for air bubbles in the syringe. Gently tap the syringe to make any air bubbles rise to the top of the syringe. Slowly push the plunger up to remove the air bubbles. If you push solution back into the ENBREL® vial, slowly pull back on the plunger to again draw the correct amount of solution back into the syringe.
    • Remove the syringe and needle from the ENBREL® vial. Keep the needle attached to the syringe and insert the 25-gauge needle straight down into the needle cover in the ENBREL® dose tray. You should hear a “snap” when the needle is secure in the needle cover. Once the needle is secure in the needle cover, remove the 25-gauge needle from the syringe and dispose of the needle in a puncture-resistant container.
    • Attach the 27-gauge needle onto the tip of the syringe until it fits snugly. Do not remove the needle cover from the syringe. Place the syringe on your flat work surface until you are ready to inject ENBREL®.

    STEP 4: Choosing and Preparing an Injection Site

    • Three recommended injection sites for ENBREL® include: (1) the front of the middle thighs; (2) the abdomen, except for the two-inch area right around the navel; and, (3) the outer area of the upper arms.
    • Rotate the site for each injection. Do not inject into areas where the skin is tender, bruised, red, or hard. Avoid areas with scars or stretch marks.
    • If you have psoriasis, you should try not to inject directly into any raised, thick, red, or scaly skin patches or lesions.
    • To prepare the area of skin where ENBREL® is to be injected, wipe the injection site with a new alcohol swab. Do not touch this area again before giving the injection.

    STEP 5: Injecting the ENBREL® Solution

    • Pick up the syringe from your flat work surface. Hold the barrel of the syringe with one hand and pull the needle cover straight off. Do not touch the needle or allow it to touch any surface. Do not touch or bump the plunger. Doing so could cause the liquid to leak out.
    • With one hand, gently pinch the cleaned area of skin and hold it firmly. With the other hand, hold the syringe (like a pencil) at a 45-degree angle to the skin.
    • With a quick, "dart-like" motion, push the needle into the skin.
    • After the needle is inserted, let go of the skin. Pull the plunger back slightly. If no blood appears in the syringe, slowly push the plunger all the way down to inject ENBREL®.If blood comes into the syringe, do not inject ENBREL® because the needle has entered a blood vessel. Withdraw the needle and repeat the steps to prepare for an injection. Do not use the same syringe and needle. Dispose of the used needle and syringe in a puncture-resistant container.
    • When the syringe is empty, pull the needle out of the skin, being careful to keep it at the same angle as inserted.
    • There may be a little bleeding at the injection site. You can press a cotton ball or gauze over the injection site for 10 seconds. Do not rub the injection site. If needed, you may cover the injection site with a bandage.
    • If your doctor has instructed you to take two ENBREL® injections on the same day, repeat the steps to prepare and give an injection of ENBREL®. Choose and prepare a new injection site for the second injection.
    • FOR FREE-HAND METHOD - If there is enough solution left in the ENBREL® vial for another dose, refrigerate the ENBREL® vial (in the dose tray) after use. Otherwise, discard the ENBREL® vial and any remaining solution.

    STEP 6: Disposing of Supplies

    The syringe, needles, and vial adapter should NEVER be reused. NEVER recap a needle.

    Dispose of both the used needle and syringe as instructed by your healthcare provider, or by following these steps:

    • Do not throw the used needle or syringe in the household trash or recycle.
    • Place the used needle and syringe in a hard plastic disposal container with a screw-on cap or a metal container with a plastic lid, such as a coffee can, labeled “used syringes.” If a metal container is used, cut a small hole in the plastic lid and tape the lid to the metal container. If a hard plastic container is used, always screw the cap on tightly after each use. Do not use glass or clear plastic containers. Puncture-resistant containers may also be purchased at your local pharmacy.
    • When the container is full, tape around the cap or lid to make sure the cap or lid does not come off.
    • You should always check first with your healthcare provider for instructions on how to properly dispose of a filled disposal container. There may be special state and local laws for disposing of used needles and syringes. Do not throw the disposal container in household trash. Do not recycle.
    • Always keep the container out of the reach of children.
    • The ENBREL® vials, vial adapters, and used alcohol swabs should be placed in the trash. The dose tray and cover may be recycled.

    A healthcare provider familiar with ENBREL® should answer all questions. A toll-free information service is also available: 1-888-4ENBREL (1-888-436-2735).
