Etanercept is used alone or in combination with other medications to reduce the pain and swelling associated with rheumatoid
arthritis, juvenile rheumatoid arthritis, and psoriatic arthritis. Etanercept is in a class of medications called tumor-necrosis
factor (TNF) inhibitors. It works by blocking the activity of TNF, a substance in the body that causes swelling and joint
damage in arthritis.
Etanercept comes as a solution to inject subcutaneously (under the skin). It is usually injected twice a week. Follow the
directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Use etanercept exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
You can inject etanercept in the thigh, stomach, or upper arm. To reduce the chances of soreness or redness, use a different
site for each injection.The new injection should be given at least 1 inch away from the previous injection. Do not inject
into an area where the skin is tender, bruised, red, or hard.
Dispose of used needles and syringes in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose
of the puncture-resistant container.
Before you use etanercept for the first time, read the manufacturer's information for the patient that comes with it. Ask
your doctor or pharmacist to show you how to inject etanercept.
Before preparing an etanercept dose, wash your hands with soap and water. To prepare the area of the skin where you will inject
etanercept, wipe it with an alcohol swab.
To prepare and inject etanercept, follow these steps:
- Remove the pink plastic cap from the etanercept vial. Do not remove the gray stopper or silver metal ring.
- Clean the gray stopper on the vial with an alcohol swab. Place the vial on a flat surface. Do not touch the stopper.
- Slide the plunger into the syringe and turn it clockwise until it becomes more difficult to turn.
- Pull the needle cover straight off the syringe. Do not touch the needle or allow it to touch anything, and do not push the plunger.
- Insert the needle straight down through the center ring of the gray stopper of the etanercept vial. You will hear a pop as the needle goes through the stopper. You should see the needle tip in the stopper window.
- Push the plunger down very slowly until all the liquid from the syringe is in the vial. Leave the syringe in place, and gently swirl the vial between your fingers in a circular motion to dissolve the powder. Do not shake.
- The powder should dissolve in less than 10 minutes. The solution should be clear and colorless. There may be some bubbles in the solution. Do not inject the solution if it contains lumps, flakes, or particles.
- To withdraw the solution from the vial, turn the vial upside down and hold it at eye level. Slowly pull the plunger down to the marking on the side of the syringe that corresponds to the correct dose. Make sure to keep the tip of the needle in the solution.
- With the needle still inserted in the vial, check for air bubbles in the syringe. Gently tap the syringe to make any air bubbles rise to the top of the syringe. Then slowly push the plunger up to remove the air bubbles. If any solution is pushed back into the vial, slowly pull back on the plunger to draw the solution back into the syringe.
- Remove the syringe and needle from the vial. Be careful not to touch the needle or touch it to any surface.
- Gently pinch the cleaned area of skin with one hand and hold it firmly. With the other hand, hold the syringe like a pencil at a 45 degree angle to the skin.
- Push the needle into the skin, and let go of the skin with the other hand.
- Use the other hand to slowly push the plunger down to inject etanercept.
- When the syringe is empty, pull the needle out of the skin, being careful to keep it at the same angle as when it was inserted.
If it is hard for you to prepare a dose because of arthritis of the hand, you may use another method to prepare etanercept.
Speak to your health care provider and refer to the manufacturer's information.
Some children may use one vial of etanercept solution for more than one dose. Do not mix the contents of one etanercept vial
with the contents of another vial. Ask your health care provider for directions on how to prepare a dose from a vial that
was already used.
