Patient information: uses, side effects, how to take - Ruconest

What is RUCONEST?

RUCONEST is an injectable medicine that is used to treat acute angioedema attacks in adult and adolescent patients with Hereditary Angioedema (HAE). HAE is caused by a shortage of a protein called C1 esterase inhibitor, that is present in your blood and helps control inflammation (swelling) and parts of the immune system. A shortage of C1 esterase inhibitor can lead to repeated attacks of swelling, pain in the abdomen, difficulty breathing and other symptoms. RUCONEST contains C1 esterase inhibitor.

Who should not use RUCONEST?

You should not use RUCONEST if you have a known or suspected allergy (hypersensitivity) to rabbits or rabbit-derived products.

You should not use RUCONEST if you have experienced life-threatening immediate hypersensitivity reactions, including anaphylaxis, to RUCONEST or to any other C1 esterase inhibitor product.

RUCONEST is not indicated for use in children under the age of 13 years.

What should I tell my healthcare provider before using RUCONEST?

Tell your healthcare provider about all of your medical conditions, including if you:

  • have an allergy to rabbits since this can put you at high risk of a serious allergic reaction with RUCONEST. These allergy symptoms could include runny nose, itchy nose, sneezing, coughing, wheezing, difficulty breathing or watery eyes when you are near rabbits.
  • are pregnant or planning to become pregnant. It is not known if RUCONEST can harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if RUCONEST passes to your milk and if it can harm your baby.

Tell your healthcare provider and pharmacist about all of the medicines you take, including all prescription and non-prescription medicines such as over-the-counter medicines, supplements, or herbal remedies.

How is RUCONEST given?

RUCONEST will be slowly injected into your vein (intravenous injection). Before injection, the RUCONEST powder must be dissolved using sterile Water for Injection. The dose will be determined based on your weight.

Most of the time a single dose of RUCONEST is enough to treat an attack, but a second dose may be needed.

What are the possible side effects of RUCONEST?

Like all medicines, RUCONEST can cause side effects, although not everybody gets them.

Allergic reactions may occur with RUCONEST. Call your healthcare provider or the emergency department immediately if you have any of the following symptoms after receiving RUCONEST:

  • wheezing
  • difficulty breathing
  • chest tightness
  • turning blue (look at lips and gums)
  • fast heartbeat
  • swelling
  • faintness
  • rash
  • hives

In clinical studies, the most severe side effect reported in a person who received RUCONEST was a severe allergic reaction in a subject who was allergic to rabbits.

Other side effects patients experienced during clinical research studies include:

  • headache
  • nausea
  • diarrhea

These are not all the possible side effects of RUCONEST.

  • The protective cap is missing
  • The expiration date (see label) has passed

Step 3: Wash hands.

  • Thoroughly wash and dry your hands

DOSAGE VERIFICATION

Discuss this section with your healthcare provider to ensure that the correct dose of RUCONEST is administered.

  • The dose of RUCONEST and volume (mL) of reconstituted solution to be administered is based on body weight show in the chart below. No more than 2 vials may be combined for a single dose.
Body weightRUCONEST dose for intravenous injectionVolume (mL) of reconstituted solution (150 U/mL) to be administered
<84 kg (185.2 lb)50 U per kg of body weightBody weight in kg divided by 3
≥84 kg (185.2 lb)4200 U (2 vials)28 mL

RECONSTITUTION

The procedures below are provided as general guidelines for the reconstitution of RUCONEST.

Step 1: Ensure that the RUCONEST vials and the diluent vial are at room temperature (range of 68°F - 77°F or 20°C - 25°C).

The RUCONEST vial is for single

Step 2: Place the 2 RUCONEST vials and the diluent vial on a flat surface and remove the flip caps on each vial

  • Wipe the vial stoppers with the antiseptic wipes provided and allow to dry for 30 seconds.
  • Do not blow on the stoppers after wiping.
  • Do not touch the stopper with your hands, or allow it to touch any surface.

Step 3: Peel back the covers from the clear plastic vial adapter packages.

  • Leave the adapters in their packages.

Step 4: While holding the adapter in its package, place the first adapter over the diluent vial and press down until the device snaps into place.

  • Leave the package on the adapter until you are ready to attach the syringe.

Step 5: Now, place a 2nd adapter over a RUCONEST vial and press down until it snaps into place.

Repeat if your dose requires a 2nd RUCONEST vial.

Step 6: Lift the package away from the diluent adapter.

Step 7: Remove syringe from package and withdraw sterile water for injection from the diluent vial.

  • With vial on a flat surface, attach syringe to adapter on diluent vial by rotating syringe clockwise.
  • Turn diluent vial upside down and slowly withdraw either 14 mL (if using 1 RUCONEST vial) or 28 mL (if using 2 RUCONEST vials) of diluent into syringe by gently pulling back on the plunger.
  • There will still be some diluent left in the vial.
  • Place the diluent vial back on a flat surface and detach syringe by gently pulling the syringe and rotating counterclockwise.

Step 8: Transfer the diluent to the RUCONEST vial.

  • Remove the package from the adapter connected to one of the RUCONEST vials.
  • Attach the syringe holding the diluent to the adapter on the RUCONEST vial by inserting the tip into the adapter opening while firmly pushing and rotating the syringe clockwise.
  • Slowly press 14 mL of diluent into the RUCONEST vial.
  • Add the diluent slowly to avoid forceful impact on the powder.
  • Note: Leave the syringe attached to the vial after adding the diluent.

Step 9: Swirl the vial to mix. Do this slowly to avoid foaming.

Repeat Steps 8 and 9 if you are using a second RUCONEST vial. Remove syringe from the first RUCONEST vial prior to attaching to the second vial.

Step 10: Inspect RUCONEST vial(s) visually.

  • After reconstitution and prior to administration, inspect the RUCONEST vials visually for particulate matter and discoloration.
  • The reconstituted solution should be colorless, clear, and free from visible particles.
  • Do not use the vial if it looks cloudy, contains particles, or has changed color.

Step 11: With the syringe still connected to the RUCONEST vial, turn the vial upside down.

  • Slowly withdraw your dose of RUCONEST by gently pulling back on the plunger.
  • Once you have withdrawn your dose, turn the vial right side up and place on a flat surface. Disconnect the syringe by gently pulling and rotating counterclockwise.

Step 12: Repeat Step 11 and withdraw additional reconstituted RUCONEST from the second RUCONEST vial (if needed).

  • Withdraw only as much as is needed based on your body weight.
  • Disconnect the syringe, for use as described in the next section.

SELF-ADMINISTRATION (intravenous injection)

Your healthcare provider will teach you how to safely administer RUCONEST. It is important that you inject RUCONEST directly into a visible vein. Do not inject into surrounding tissues or an artery. Once you learn how to self-administer, follow the instructions provided below. The reconstituted solution should be used within 8 hours and should be cooled but not be frozen.

Step 1: Assemble supplies.

  • Gather the RUCONEST syringe, the following disposable supplies (not provided with RUCONEST), and other items:

    • Standard butterfly catheter infusion set (IV administration set with winged adapter and needle)
    • Sterile syringe
    • Tourniquet
    • Sterile gauze and tape or transparent dressing
    • Bandage (adhesive dressing)
    • Gloves (if recommended by your healthcare provider)
    • Antiseptic wipe for cleaning skin
  • Other items (not shown)
  • Clock or stopwatch to monitor time
  • Sharps or other disposal container
  • Treatment diary

Step 2: Clean surface.

  • Thoroughly clean a table or other flat surface using one or more of the antiseptic wipes.

Step 3: Prime the infusion set.

As instructed by your healthcare provider:

  • To prime (fill) the infusion tubing, connect the syringe filled with RUCONEST to the infusion set tubing and gently push on the syringe plunger to fill the tubing with RUCONEST.

Step 4: Prepare the approved IV injection site.

  • Apply a tourniquet above the site of the infusion.
  • Prepare the injection site by wiping the skin well with an antiseptic wipe, beginning at the center and working outward in a circular motion.
  • Allow the site to dry.

Step 5: Start infusion.

Follow the instructions provided by your healthcare provider.

  • Take off the needle sheath.
  • Hold both wings of the butterfly between the thumb and the index finger with the obliquely cut (slanted) opening of the butterfly needle pointing upward.
  • Insert the butterfly needle of the infusion set into your vein (insert as flat to skin surface as possible).
  • Use sterile gauze and tape or transparent dressing to hold the needle in place.
  • Make sure the needle is in a vein:

    • Gently pull back on the syringe plunger and check to see if blood is in the tubing.
    • If there is blood present, then the needle is in a vein.
    • If there is no blood, remove the needle and repeat this step using a new needle, new administration tubing, and a different injection site.
  • Remove the tourniquet.
  • Note: Inject RUCONEST slowly over approximately 5 minutes.

Step 6: Cover the injection site and clean up.

After all of the RUCONEST has been infused:

  • Withdraw the butterfly needle along the line that it was inserted.
