When to use CETROTIDE
Your doctor will tell you when to inject CETROTIDE.
How to inject CETROTIDE
CETROTIDE is for injection under the skin of the lower abdominal wall. The injection
site should be changed everyday to lessen possible injection site reactions.
Your first injection of CETROTIDE should be given by your doctor or nurse. You should
remain under their supervision after this injection in case of allergic reaction.
After the first injection, you may administer CETROTIDE yourself.
Do not attempt self-injection until you are sure of how to do it.
Follow all instructions given to you by your doctor or nurse carefully. Follow these
steps:
Wash your hands. It is important that your hands and all items you use are as clean
as possible.
Lay out everything you need on a clean surface (one vial of powder, one pre-filled
syringe with sterile water, one needle with a yellow mark for injecting the sterile
water into the vial and drawing the medicine from the vial, one needle with a grey
mark for injecting the medicine and alcohol swabs (not provided in the pack)).
Remove the flip-off cap from the vial and wipe the aluminium ring and the rubber stopper
with an alcohol swab.
2.
Mixing: Adding the water from the pre-filled syringe to the powder in the vial
Screw the needle with yellow mark onto the syringe. Carefully remove the needle cover.
Push the needle through the centre of the rubber stopper of the vial. Inject the water
into the vial by slowly pushing the plunger of the syringe.
With the needle still in the vial, gently swirl 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 solution.
Do not use the dissolved solution if it contains particles or is not clear.
Turn the vial upside down. Gently draw the whole contents of the vial into the syringe.
It is important to withdraw the entire contents of the vial.
Unscrew and discard the yellow needle into your sharps container.
Unwrap the needle with the grey mark on it. Screw the grey needle onto the syringe
and remove the cap from the grey needle.
Hold the syringe with the grey needle pointing upwards and check for any air bubbles.
Gently flick the syringe until all the air collects at the top and push the plunger
until the air bubbles are gone.
Do not touch the needle or allow the needle to touch any surface.
Choose an injection site in the area of lower abdominal wall, preferably around the
navel. Clean the skin at your chosen injection site with an alcohol swab if required.
Hold the syringe with the grey needle in one hand. Gently pinch up the skin surrounding
the site of injection and hold firmly with the other hand.
Slowly push the grey needle completely into your skin at an angle of about 45 to 90
degrees.
Once the needle has been inserted completely, release your grasp of the skin.
Slowly push down the plunger until all the solution has been injection. After all
the solution is injected, withdraw the needle slowly.
Gently press down the injection site with a cotton pad.
Dispose of both the injection needle and the syringe in your sharps container. Do
not re-use them.
Use a new vial and syringe for each use.
