How should I use ganirelix (Antagon, Ganirelix Acetate)?
Ganirelix is injected under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Ganirelix is usually given once daily for several days in a row during certain phases of your fertility treatment cycle. Follow your doctor's instructions and try not to miss any doses.
Each single use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.
Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
During your treatment with ganirelix, your blood may need to be tested often. Visit your doctor regularly. You must remain under the care of your doctor while using ganirelix.
Store the prefilled syringe at room temperature, away from heat, moisture and light.
