Spevigo® 150 mg solution for injection in pre-filled syringe

This “Instructions for use” contains information on how to inject Spevigo if the prescribed dose for you or your child requires 2 pre-filled syringes of Spevigo 150 mg.

Getting to know Spevigo

The pre-filled syringe contains the active substance spesolimab in a solution for subcutaneous injection that helps to deliver a fixed dose of spesolimab.

Before you start using this medicine on your own or your child, first make sure that you get trained by your doctor or nurse. Then read the package leaflet and these instructions for use to make sure you get the correct dose. If you are visually impaired and cannot see well, you must be assisted by a trained caregiver.

If you have further questions, ask your doctor, pharmacist or nurse.

Spevigo is for single use. Do not reuse the pre-filled syringe.

This is what Spevigo pre-filled syringe looks like

Spevigo is a pre-filled syringe with a safety cover. The needle is pulled back into the safety cover after injection.

body

Your healthcare professional has prescribed a dose of Spevigo for you or your child that requires two injections to deliver a complete dose. You must inject the contents of both pre-filled syringes that come in the carton to deliver the complete dose.

Important information you need to know before injecting Spevigo

  • Do not use the pre-filled syringe until you have been shown the right way to give

    the injection and have read and understood these handling instructions.

  • Inspect the carton that the product comes in to be sure that you have the correct

    medicine, the correct number of pre-filled syringes for your or your child’s prescribed dose, for any damage, and the expiry date.

  • Do not remove the cap until you are ready to inject.
  • Do not use Spevigo:

    • if the liquid is cloudy or contains flakes or large particles.
    • if the expiry date (EXP) has passed.
    • if the pre-filled syringes have been dropped or look damaged.
  • It is important to keep a record of the batch number of your Spevigo.

    Every time you get a new pack of Spevigo, note down the date and the batch number (which is on the packaging after “Lot”) and keep this information in a safe place.

  • Inject Spevigo under the skin (subcutaneous injection) in either the upper thighs

    or stomach area (abdomen). Do not inject Spevigo into any other area of the body.

  • If you have any problems with your injection, do not repeat the injection steps

    with Spevigo pre-filled syringe. Call your doctor for help.

  • If you have further questions, ask your doctor or pharmacist.

    • Take the Spevigo carton out of the refrigerator and remove the pre-filled syringes from the carton.
    • Gather supplies listed on the left side and place them on a clean, flat work surface in a well-lit area.
    • If you do not have all the supplies listed, contact your pharmacist.
    • For disposal, see step 10: “Disposing of the used pre-filled syringes and caps.”

      • Clean the injection site with an alcohol wipe and let air dry.
      • Do not touch this area again before injecting.
      • Do not fan or blow on the clean area.

        • Hold the pre-filled syringe by the blue finger grip. Avoid touching the blue thumb pad.
        • Using a quick, “dart-like” motion, insert the needle into the pinched skin at about a 45-degree angle.
        • Do not move the needle while inserting or during the injection.

Important: Do not move the pre-filled syringe when inserting the needle into your skin, while injecting, or when removing the needle from your skin.

  • Put the used pre-filled syringes and caps in a sharps disposal container right away after use.
  • Do not throw away the pre-filled syringes in the household waste.
  • Your doctor, pharmacist, or nurse will tell you how to return the full sharps disposal container.
  • Do not reuse the pre-filled syringes. Important: Always keep the sharps disposal container out of the reach of children.
  • Choose a different injection site. The new injection site should be at least 2 cm away from last injection site.
  • Take the second pre-filled syringe.
  • Repeat steps 4 through 8 right away.
  • Then continue to step 10.

Important: You must inject the contents of both Spevigo pre-filled syringes to give a complete dose.

To inject Spevigo:

  • Use your thumb to slowly press down on the blue thumb pad to push the plunger rod down inside the syringe body.
  • Continue pressing on the blue thumb pad until the plunger rod has moved all the way down.
  • Make sure that the blue thumb pad cannot be pressed any further so that the built-in safety cover can be activated.
  • Slowly remove your thumb from the blue thumb pad, to move the needle out of your skin and up into the safety cover. ° Check that the thumb pad springs back and that the needle is inside the safety cover.

    ° If the needle is not inside the safety cover call your doctor. You may not have received a full dose.

  • If there is bleeding, press a cotton ball or gauze on the site for a few seconds.
  • Do not rub the injection site.
  • Apply a plaster if needed.
  • Hold the pre-filled syringe by the finger grip with one hand. With the other hand, pull the cap straight off.

    ° Do not pull on or hold the plunger rod. ° Do not twist the cap. Twisting the cap

    could damage the needle.

    ° Do not use the prefilled syringe if the

    needle is bent or damaged. If you accidentally bend the needle, do not attempt to straighten it.

  • Put the cap aside.
  • Use right away after removing the cap. ° Do not try to recap the needle.

    Re-capping can lead to needle-stick injury.

    ° Do not touch the needle or let the needle

    touch anything before injecting.

  • Gently pinch the area of cleaned skin around your injection site and hold it firmly.
  • Keep the skin pinched during the entire injection. You will inject into the pinched skin.
  • Do not let go until you have removed the needle from your skin at the end of the injection.
  • Wait 15 to 30 minutes to allow the medicine to reach room temperature to avoid discomfort during injection. Do not speed up the warming process in any way, such as using the microwave or placing the syringe in warm water.
  • Do not leave the pre-filled syringes in direct sunlight.
  • Wash your hands well with soap and water and dry them.

Check both pre-filled syringes now:

  • Check to make sure the medicine name and dose on the pre-filled syringes match your or your child’s prescription.
  • Check the expiry date (EXP) on both pre-filled syringes. Do not use if the expiry date has passed.
  • Check both pre-filled syringes for damage, cracks, and leakage. Do not use if any part of the pre-filled syringes appears cracked, broken, or is leaking.
  • Make sure the medicine in both pre-filled syringes is colourless to slightly yellow. It may contain tiny white or clear particles. Do not use if the medicine is cloudy or has flakes or large particles in it.
  • It is normal to see air bubbles, they do not need to be removed.
  • Do not use if the Spevigo pre-filled syringes have been dropped.

Prepare for the first of two injections. Remember, you will repeat the following steps with the second pre-filled syringe right away after your first injection. Two injections are needed for a complete dose.

Choose an injection site.

  • You may use an area on your:

    ° upper thighs or

    ° stomach area (abdomen), except for an

    area 5 cm around your navel (belly button).

  • Choose a different injection site each time you inject, at least 2 cm away from the last injection site.
  • Do not inject into an area near your waistline or belly button.
  • Do not inject into areas that are tender, bruised, red, hard, or scarred.
  • Do not inject through clothes.
