Indicated for: infertility

Cetrorelix is a gonadotropin-releasing hormone (GnRH) antagonist primarily used in reproductive medicine to prevent premature ovulation in women undergoing assisted reproductive techniques, such as in vitro fertilization (IVF). It works by blocking GnRH receptors, thereby inhibiting the secretion of luteinizing hormone (LH).
The medication is administered as a subcutaneous injection, usually during the follicular phase of the menstrual cycle, as directed by a specialist. The dosage and duration of treatment are adjusted based on the patient's response.
Patients should be closely monitored to assess ovarian response and detect potential side effects. It is important for patients to adhere to the treatment schedule and inform their doctor of any unusual symptoms.
Common side effects include injection site reactions, nausea, headache, and abdominal discomfort. In rare cases, severe allergic reactions or ovarian hyperstimulation syndrome may occur. Patients should be informed of these risks before starting treatment.
