Ganirelix may be administered by your healthcare provider or your doctor may want you to
administer this medication at home. If you are administering the medication at home, your doctor will
give you detailed instructions on how and where to administer the injection. In general, the injection
should be administered as follows:
-
Wash your hands thoroughly with soap and water.
-
Use an alcohol wipe to clean an area about two inches
around the intended injection site (usually an area around the bellybutton or on the upper thigh).
Allow the skin to dry for at least one minute.
-
Remove the needle cover.
-
Pinch up an area of skin between the finger and thumb.
Insert the needle at a 45 to 90 degree angle to the skin at the base of the pinched-up skin.
-
Pull back slightly on the plunger of the syringe. When the
needle is correctly positioned under the skin, it should be difficult to pull back on the plunger. If
any blood is drawn into the syringe, the needle tip has entered a vein or artery. If this happens,
withdraw the needle slightly and reposition the needle without removing it from the skin.
Alternatively, remove the needle and use a new, sterile, prefilled syringe.
-
Once the needle is correctly positioned, depress the plunger
slowly and steadily so the solution is correctly administered and the skin is not damaged.
-
Pull the needle out quickly and apply pressure to the
injection site with an alcohol swab.
Rotate injection sites as directed by your healthcare provider.
Never reuse a needle or syringe. Dispose of all needles and syringes in an appropriate, puncture
resistant disposal container.
Your healthcare provider may want to perform blood tests or other forms of monitoring during
treatment with ganirelix to evaluate progress and side effects.
