Why do I need this medicine?

Oprelvekin is used to prevent severe thrombocytopenia (a condition characterised by a low platelet count) and helps reduce the need for platelet transfusion after certain chemotherapy treatments.

How do I use this medicine?

Your doctor or nurse will administer the injection for you. If you or a caregiver had been given the proper training on the preparation and injection techniques, you or your caregiver may do the administration.

Use Oprelvekin exactly as directed by your doctor or according to the instructions on the label. Do not administer more or less than instructed by your doctor.

How to use this medicine:
  1. Ensure that you receive all the supplies that you need (e.g. alcohol wipes, cotton balls, syringe, needle, puncture proof container).
  2. Wash your hands with soap and water.
  3. Flip off the protective cap of Oprelvekin bottle. Wipe the rubber stopper with a sterile alcohol wipe.
  4. Hold the bottle of Oprelvekin with one hand. Use the other hand to push the needle of the pre-filled syringe containing sterile water for injection, through the middle of the rubber stopper. Carefully aim the needle to the side of the bottle and slowly press the plunger of the syringe. Take the needle out of the rubber stopper after injecting all of the sterile water for injection.
  5. Gently swirl the bottle until all the Oprelvekin powder has dissolved. Do not shake the bottle. The fluid inside the bottle should be clear, colourless, and free from visible particles.
  6. Hold the bottle of dissolved Oprelvekin upside down with one hand. Use the other hand to hold and push the needle of the syringe through the bottle rubber stopper. Gently pull the plunger until the you collected the prescribed amount of medicine.
  7. This medicine is to be injected subcutaneously (into the fatty layer under the skin, usually in the abdomen, thigh, hip or upper arm). Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1 inch away from the previous injection site. Do not inject onto areas of your skin that are red, bruised, tender, hard or not intact.
  8. Wipe the injection site with alcohol swabs and let it dry.
  9. Gently pinch the skin at the injection site with one hand and pick up the syringe with other hand. Insert the needle in the pinched area of the skin at a 45-degree angle using a dart-like motion. Release the pinched skin after the needle is completely inserted. Push the plunger all the way down until all the solution is injected.
  10. Slowly release the needle and gently pull it out of the skin. Place a cotton ball over the injection site and press for 3 to 5 seconds.
  11. Dispose your used needles and syringes according to your doctor or pharmacist’s instructions. Do not throw away in household trash.
If you have problems or do not understand the instructions, ask your doctor or pharmacist.

The dose of Oprelvekin will be decided by your doctor. Your doctor will advise you on the course of the treatment depending on your condition.

What should I do if I have forgotten to use this medicine?
