Proper Use

Drug information provided by: Micromedex

A doctor or other trained health professional will give you or your child this medicine in a hospital or clinic setting. This medicine is given through a needle placed in one of your veins.

This medicine may also be given at home to patients who do not need to be in a hospital or clinic. If you or your child are using this medicine at home, your doctor will teach you how to prepare and inject the medicine. Make sure you understand all of the instructions before giving yourself an injection. Your dose may change based on where you are bleeding. Do not use more medicine or use it more often than your doctor tells you to.

Use only the brand of this medicine that your doctor prescribed. Not all brands are prepared in the same way and the dose may be different.

Every package of medicine comes with a patient information leaflet. Read and follow the instructions carefully. Ask your doctor if you have any questions.

To prepare the medicine using 2 bottles (vials) or containers:

  • Take the bottles of powder medicine and liquid (diluent) out of the refrigerator and warm them to room temperature.
  • Wipe the rubber surface of the bottles with an alcohol swab and allow them to dry.
  • Follow the specific directions for your brand of medicine when you prepare the injection.
  • Add the liquid to the powder using the special transfer needle or transfer device that comes with the package.
  • When injecting the liquid into the dry medicine, aim the stream of liquid against the wall of the container of dry medicine to prevent foaming.
  • Swirl the bottle gently to dissolve the medicine. Do not shake the bottle. Shaking will create foam in the mixture.
  • Check the mixture to make sure it is clear. Do not use the medicine if you can see anything solid in the mixture or if the mixture is cloudy.
  • Use a plastic disposable syringe to remove the mixture from the bottle. Use a special filter needle if your brand of medicine provides one.
  • Give the injection as directed by your doctor.
  • If you are using more than one bottle of medicine for your dose, prepare the second bottle the same way. Add the mixture from the second bottle to the same syringe.

To prepare the medicine using a prefilled dual-chamber syringe (Xyntha®):

  • Take the prefilled dual-chamber syringe out of the refrigerator and warm it to room temperature.
  • The dual-chamber syringe has the powder medicine in one part and the liquid (diluent) in the second part of the syringe.
  • Attach the plunger rod to the syringe according to the directions. Keep the syringe pointed up to prevent leaking of the liquid.
  • Remove the white seal and the grey rubber tip cap. Put the blue vented cap on the syringe. Do not touch the open ends of the syringe and the blue cap.
  • Slowly push the plunger until the 2 stoppers inside the syringe are together. This will push all of the liquid into the chamber with the powder medicine.
  • Keep the syringe pointed up and gently swirl the syringe to mix the liquid and powder.
  • Check the mixture to make sure it is clear. Do not use the medicine if you can see anything solid in the mixture or if the mixture is cloudy.
  • Keep the syringe pointed up and push the plunger until most of the air is removed.
  • A special infusion set comes with the package. Remove the blue cap and attach the infusion set to the syringe.
  • Give the injection as directed by your doctor.
  • If you are using more than one syringe of medicine for your dose, prepare the second dual-chamber syringe the same way. The mixture from each syringe will be combined together in a separate syringe before your injection. Your doctor will show you how to do this.

Use the mixture within 3 or 4 hours after it is prepared. It must not be stored and used later. Do not put the mixture in the refrigerator.

Do not reuse syringes and needles. Put used syringes and needles in a puncture-resistant disposable container, or dispose of them as directed by your doctor.

Talk to your doctor before traveling. You should plan to bring enough medicine for your treatment when traveling.
