Cetrotide (Cetrorelix) belongs to the class of medications called GnRH antagonists. Cetrotide (Cetrorelix) is used to prevent premature ovulation in women undergoing ovarian stimulation. It blocks the effects of gonadotropin-releasing hormone (GnRH). GnRH controls the secretion of another hormone, called luteinizing hormone (LH), a hormone that starts ovulation (release of an egg) during the menstrual cycle. Cetrotide (Cetrorelix) allows the release of an egg to be controlled so it is released at the best time for pregnancy to occur.

Your doctor may have suggested Cetrotide (Cetrorelix) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using Cetrotide (Cetrorelix), speak to your doctor. Do not stop using Cetrotide (Cetrorelix) without consulting your doctor.

Do not give Cetrotide (Cetrorelix) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Cetrotide (Cetrorelix) if their doctor has not prescribed it.



The usual dose of Cetrotide (Cetrorelix) is 0.25 mg once daily injected under the skin. Cetrotide (Cetrorelix) should be injected under the skin of the lower abdominal wall as directed by your doctor. If you are using Cetrotide (Cetrorelix) daily, use a different injection site each day to reduce irritation.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Cetrotide (Cetrorelix) is best injected under the skin of the lower abdomen a few inches below your navel. Each day, use the alternate side of your lower abdomen (e.g., left or right) to prevent soreness.

Your doctor or other health care professional will show you exactly how to mix and draw up the medication into the needles and how to inject it. Read the information leaflet carefully and ask your doctor any questions you may have.

Once the dose of medication has been prepared, it should be used immediately. Discard any unused material after use. Do not use your injectable solution if it appears cloudy, lumpy, or discoloured.

It is important to use Cetrotide (Cetrorelix) exactly as prescribed by your doctor. If you miss a dose, contact your doctor for instructions. Do not take a double dose to make up for a missed one.

Store Cetrotide (Cetrorelix) in a cool dry place between 2°C and 25°C. Do not freeze. Protect it from heat, moisture, and light and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
