Patient information: uses, side effects, how to take - Cetrotide
How should you use Cetrotide®?
You may self-inject Cetrotide® after special instruction from your doctor.
To fully benefit from Cetrotide®, please read carefully and follow the instructions given below, unless your doctor advises you otherwise.
Cetrotide® is for injection under the skin of the lower abdominal area, preferably around, but staying at least one inch away from the belly button. Choose a different injection site each day to minimize local irritation.
Dissolve Cetrotide® powder only with the water contained in the pre-filled syringe. Do not use a Cetrotide® solution if it contains particles or if it is not clear.
Before you inject Cetrotide® yourself, please read the following instructions carefully:
Directions for using Cetrotide® 0.25 mg with the enclosed needles and pre-filled syringe:
| 1. | Wash your hands thoroughly with soap and water. |  |
| 2. | On a clean flat surface, lay out everything you need (one vial of powder, one pre-filled syringe, one injection needle with a yellow mark, and one injection needle with a grey mark). |  |
| 3. | Flip off the plastic cover of the vial. Wipe the aluminum ring and the rubber stopper with an alcohol swab. |  |
| 4. | Take the injection needle with the yellow mark and remove the wrapping. Take the pre-filled syringe and remove the cover. Twist the needle on the syringe and remove the cover of the needle. |  |
| 5. | Push the needle through the center of the rubber stopper of the vial. Inject the water into the vial by slowly pushing down on the plunger of the syringe. |  |
| 6. | Leave the syringe in the vial. While carefully holding the syringe and vial, swirl gently to mix the powder and water together. When it is mixed, it will look clear and have no particles in it. Do not shake or you will create bubbles in your medicine. |  |
| 7. | Draw the total contents of the vial into the syringe. If liquid is left in the vial, invert the vial, pull back the needle until the opening of the needle is just inside the stopper. If you look from the side through the gap in the stopper, you can control the movement of the needle and the liquid. It is important to withdraw the entire contents of the vial. |  |
| 8. | Detach the syringe from the needle and lay down the syringe. Take the injection needle with the grey mark and remove its wrapping. Twist the needle on the syringe and remove the cover of the needle. |  |
| 9. | Invert the syringe and push the plunger until all air bubbles have been pushed out. Do not touch the needle or allow the needle to touch any surface. |  |
| 10. | Choose an injection site in the lower abdominal area, preferably around, but at least one inch away from the belly button. Choose a different injection site each day to minimize local irritation. Take a second alcohol swab and clean the skin at the injection site and allow alcohol to dry. Inject the prescribed dose as directed by your doctor, nurse or pharmacist. |  |
| 11. | Use the syringe and needles only once. Dispose of the syringe and needles immediately after use (put the covers on the needles to avoid injury). A medical waste container should be used for disposal. |  |
