CETROTIDE® is used in Assisted Reproductive Technology (ART) treatments, such as in vitro fertilisation (IVF), to prevent premature ovulation. By blocking the action of gonadotropin-releasing hormone (GnRH), CETROTIDE® suppresses the release of luteinising hormone (LH), ensuring that eggs develop fully before retrieval. This helps improve the timing and success of ART procedures.

CETROTIDE® is administered as a subcutaneous injection in the lower abdomen. The typical dosage is 250 micrograms once daily, given at 24-hour intervals, starting on specific days of the ovarian stimulation cycle as directed by your fertility specialist.

Alternatively, a single dose of 3 mg may be prescribed, which provides suppression for up to four days.

If you forget to take a dose, contact your fertility clinic or doctor immediately for advice.

Do not administer a double dose to make up for the missed one.

Timing is critical in fertility treatments, so follow your doctor’s instructions closely.

In case of accidental overdose, seek medical attention promptly.

Symptoms of overdose may include nausea, dizziness, or abdominal discomfort.

Contact the Poisons Information Centre (Australia: 13 11 26) or your doctor or pharmacist for guidance.

Store CETROTIDE® in a refrigerator at 2°C to 8°C. Do not freeze the medication.

If refrigeration is unavailable, CETROTIDE® can be stored below 30°C for a single period of up to three months, after which it must be discarded.

Keep the medication in its original packaging to protect it from light and moisture, and ensure it is out of reach of children.

Common side effects include mild redness, swelling, or itching at the injection site, which usually resolves within hours. Other possible side effects include headaches, nausea, and fatigue.

Rare but serious allergic reactions, such as difficulty breathing, swelling of the face or throat, or hives, require immediate medical attention.

Contact your doctor if you experience symptoms of Ovarian Hyperstimulation Syndrome (OHSS), such as severe pelvic pain, nausea, vomiting, or sudden weight gain.

CETROTIDE® may interact with other medications, including hormonal treatments.

Inform your doctor about all medications, supplements, or herbal products you are taking to avoid potential interactions.

Your fertility specialist will guide you on how to safely incorporate CETROTIDE® into your treatment plan.

How does CETROTIDE® work in fertility treatments? CETROTIDE® prevents premature ovulation by blocking the action of GnRH, which suppresses the release of LH. This ensures that eggs mature fully before retrieval, improving the timing and success of ART procedures.

Can I administer CETROTIDE® myself? Yes, if your doctor or nurse has trained you in the proper injection technique. CETROTIDE® is given as a subcutaneous injection in the lower abdomen. Follow the instructions provided by your healthcare team carefully.

What should I do if I experience side effects? Mild side effects, such as redness or swelling at the injection site, are common and usually temporary. If you experience severe symptoms, such as difficulty breathing or signs of OHSS, contact your doctor immediately. Your healthcare team is here to support you.

Can CETROTIDE® be used during pregnancy? No, CETROTIDE® must not be used during pregnancy. It is specifically designed for use during ovarian stimulation cycles before conception. If you suspect you may be pregnant, inform your doctor immediately.

How should I store CETROTIDE®? CETROTIDE® should be stored in a refrigerator at 2°C to 8°C. If refrigeration is unavailable, it can be stored below 30°C for up to three months. Always keep the medication in its original packaging to protect it from light and moisture.
