Cetrorelix
About Cetrorelix
Cetrorelix is a prescription injection used to support fertility treatments, specifically assisted reproductive technologies like in vitro fertilisation (IVF). It is prescribed to prevent your ovaries from releasing eggs too early, which ensures they can mature properly before collection. This medical purpose is vital for helping increase the chances of a successful pregnancy.
This medicine must be injected consistently at the same time every day to maintain its protective effect on your cycle. Since it is given as an injection under the skin, its absorption is not affected by whether you take it with or without food. Combining this treatment with healthy habits, like eating a balanced diet and reducing physical and emotional stress, can help support your body's response to the fertility cycle.
Many women experience only mild reactions at the injection site, such as redness, itching, or swelling. However, it is essential to contact your doctor immediately if you experience severe symptoms like intense abdominal pain, bloating, or trouble breathing, which could indicate a serious condition called ovarian hyperstimulation syndrome.
Before starting this medication, talk to your doctor if you have a history of active allergies or severe kidney or liver damage. Specifically, you should not take this medicine if you are already pregnant, breastfeeding, or suffer from severe kidney damage.
Be sure to inform your healthcare provider about all other medicines you are taking, as well as your alcohol and smoking habits, because they can alter your body's hormonal response and impact the success of your fertility treatment. Additionally, this medication is not intended for pregnant or breastfeeding women, nor is it designed for use in elderly individuals.

Patients Concern
Disease/Condition Glossary
Female infertility: Infertility is unable to become pregnant after trying for a year. Female infertility may be caused due to different factors affecting ovulation (release of an egg from the ovary), fertilization (fusion of sperm and egg), and implantation (fertilized egg attaches to uterus lining). The risk factors for infertility in females include smoking, heavy alcohol consumption, obesity, underweight, increasing age, or sexually transmitted infections. Also, certain medical conditions such as uterine fibroids, endometriosis, premature ovarian failure, polycystic ovary syndrome (PCOS), hormonal imbalances, scarring from previous surgery, or pelvic inflammatory disease may cause infertility in females.
FAQs
Cetrorelix contains Cetrorelix that works by blocking a natural hormone in the body and inhibits premature ovulation (release of eggs from the ovary too early).
Cetrorelix may cause ovarian hyper-stimulation syndrome (OHSS) if used along with other medicines that cause stimulation of ovaries to develop more ready-to-be-released eggs. However, if you experience lower stomach pain with nausea or vomiting, please consult a doctor as these might be signs of OHSS.
Cetrorelix may be used in women undergoing IVF (in-vitro fertilization) treatment to prevent premature release of eggs so that mature eggs can be collected directly from ovaries. However, please consult a doctor before using Cetrorelix.

Timing is critical because the medicine blocks the ovulation-triggering hormone for only about 24 hours.

Talk to your doctor if you are unsure about your injection schedule.
Mild redness, itching, or swelling is a common reaction that usually goes away on its own within a few hours. To help prevent this, ensure you rotate your injection sites daily and do not rub the area after injecting. Talk to your doctor or pharmacist if the skin irritation gets worse or does not clear up.
During IVF, your ovaries are stimulated to grow multiple eggs. Cetrorelix prevents your body from prematurely releasing these eggs before your doctor can collect them, helping to ensure a successful retrieval process. Talk to your doctor for more details about your specific IVF protocol.
