How to mix and inject Cetrotide

1. What Cetrotide is and what it is used for

What Cetrotide is

Cetrotide contains a substance called “cetrorelix”. This substance prevents your body from releasing an egg from the ovary (ovulation) during your menstrual cycle. Cetrotide belongs to a group of medicines known as “gonadotropin-releasing hormone antagonists”.

What Cetrotide is used for

Cetrotide is one of the medicines used during “assisted reproduction techniques” to help you get pregnant. It works by immediately stopping the release of eggs. This is because if the eggs are released too early (premature ovulation), your doctor may not be able to collect them.

How Cetrotide works

Cetrotide blocks a natural hormone in your body, called LHRH (“luteinizing hormone-releasing hormone”).

  • LHRH controls another hormone, called LH (“luteinizing hormone”).
  • LH stimulates ovulation during the menstrual cycle.

This means that Cetrotide stops the chain of events that leads to the release of an egg from the ovary. When your eggs are ready to be collected, you will be given another medicine that will release them (induction of ovulation).

Doctor consultation

Not sure if this medicine is right for you?

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before you use Cetrotide

Do not use Cetrotide

  • if you are allergic to cetrorelix or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to medicines similar to Cetrotide (any other peptide hormone).
  • if you are pregnant or breast-feeding.
  • if you have severe kidney disease.

Do not use Cetrotide if any of the above applies to you. If you are in doubt, consult your doctor before using this medicine.

Warnings and precautions

Allergies

Consult your doctor before using Cetrotide if you have an active allergic problem or have had allergies in the past.

Ovarian Hyperstimulation Syndrome (OHSS)

Cetrotide is used together with other medicines that stimulate your ovaries to develop more eggs ready to be released. During or after receiving these medicines, you may suffer from OHSS. This situation occurs when your follicles develop too much and become large cysts.

To learn about the possible signs to look out for and what to do if they occur, see section 4 “Possible side effects”.

Using Cetrotide for more than one cycle

Experience with the use of Cetrotide for more than one cycle is limited. Your doctor will carefully evaluate the benefits and risks for you if you need to use Cetrotide for more than one cycle.

Liver disease

Tell your doctor before using Cetrotide if you have any liver disease. Cetrotide has not been studied in patients with liver disease.

Kidney disease

Tell your doctor before using Cetrotide if you have any kidney disease. Cetrotide has not been studied in patients with kidney disease.

Children and adolescents

Cetrotide is not indicated for use in children and adolescents.

Other medicines and Cetrotide

Tell your doctor if you are using, have recently used, or might use any other medicines.

Pregnancy and breast-feeding

Do not use Cetrotide if you are pregnant, think you may be pregnant, or are breast-feeding.

Driving and using machines

Cetrotide is not expected to affect your ability to drive and use machines.

3. How to use Cetrotide

Follow the instructions for administration of this medicine exactly as told by your doctor. If you are in doubt, consult your doctor again.

Using this medicine

This medicine is for subcutaneous injection only, just below the skin of your abdomen. To reduce skin irritation, choose a different part of your abdomen each day.

  • Your doctor should supervise the first injection. Your doctor or nurse will teach you how to prepare and inject the medicine.
  • You can give yourself the following injections, as long as your doctor has informed you about the symptoms that may indicate an allergy and the possible serious or life-threatening consequences that would require immediate treatment (see section 4 “Possible side effects”).
  • Read and follow carefully the instructions at the end of this leaflet, titled “How to mix and inject Cetrotide”.
  • You will start using another medicine on day 1 of your treatment cycle. Then, you will start using Cetrotide a few days later. (See the next section “How much to use”.)

How much to use

Inject the contents of one vial of Cetrotide once a day. It is best to use the medicine at the same time each day, leaving 24 hours between each dose.

You can choose to inject the medicine either every morning orevery evening.

  • If you inject the medicine every morning: Start your injections on the fifth or sixth day of your treatment cycle. Depending on your ovarian response, your doctor may decide to start treatment on a different day. Your doctor will tell you the exact date and time. You will continue using this medicine until the morning your eggs are collected, including that morning (induction of ovulation).

OR

  • If you inject the medicine every evening: Start your injections on the fifth day of your treatment cycle. Depending on your ovarian response, your doctor may decide to start treatment on a different day. Your doctor will tell you the exact date and time. You will continue using this medicine until the night before your eggs are collected, including that night (induction of ovulation).

If you use more Cetrotide than you should

No side effects are expected if you accidentally inject more medicine than you should. The effect of the medicine will last longer. In general, no specific measures are necessary.

If you forget to use Cetrotide

  • If you forget a dose, inject it as soon as you remember and consult your doctor.
  • Do not inject a double dose to make up for forgotten doses.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Allergic reactions

  • Redness and feeling of heat in the skin, itching (often in the groin or armpits), red, swollen, and itchy areas (hives), runny nose, rapid or irregular heartbeat, swelling of the tongue and throat, sneezing, whistling sound while breathing (wheezing), severe difficulty breathing or dizziness.

If you notice any of the side effects described above, stop using Cetrotide and consult your doctor immediately.

Ovarian Hyperstimulation Syndrome (OHSS)

This can occur due to the other medicines you are using to stimulate your ovaries.

HOW TO MIX AND INJECT CETROTIDE

  • This section explains how to mix the powder and sterile water (solvent) and then how to inject the medication.
  • Before starting to use this medication, read these instructions completely first.
  • This medication is for you only; do not allow anyone else to use it.
  • Use each needle, vial, and syringe only once.

Before You Start

  1. This medication must be at room temperature before injection. Remove it from the refrigerator approximately 30 minutes before use.
  1. Wash your hands
    • It is essential that your hands and the objects you use are as clean as possible.
  1. Place everything you need on a clean surface:
    • a vial of powder
    • a pre-filled syringe with sterile water (solvent)
    • a needle with a yellowmark to inject sterile water into the vial and withdraw the prepared medication from the vial
    • a needle with a graymark to inject the medication into your abdomen
    • two alcohol swabs (not provided in the packaging).

Mixing the Powder and Water to Prepare Your Medication

  1. Remove the vial cap
    • You will find a rubber stopper underneath; keep it in the vial.
    • Clean the rubber stopper and the metal ring with an alcohol swab.
  1. Add the water from the pre-filled syringe to the powder in the vial
    • Remove the needle cover from the needle with the yellowmark.
    • Remove the cap from the pre-filled syringe and screw on the yellow needle. Remove the needle cap.
  • Insert the yellow needle through the center of the rubber stopper of the vial.
  • Slowly push the syringe plunger to inject the water into the vial. Do not use any other type of water.
  • Leave the syringe in the rubber stopper.

  1. Mix the powder and water in the vial
    • While carefully holding the syringe and vial, gently move to mix the powder and water. Once mixed, the solution will have a clear and particle-free appearance.
    • Do not shake the vial, as it will create bubbles in the medication.
  1. Refill the syringe with the medication from the vial
    • Place the vial upside down. Then, gently pull the plunger to withdraw the medication from the vial into the syringe. Be careful not to completely separate the plunger from the plunger cap. If the plunger and cap have been separated by mistake, ensure that you discard the dose, as sterility will be lost, and prepare a new dose (start again from step 1).
    • If medication remains in the vial, pull the yellow needle until the needle tip is just inside the rubber stopper. If you look sideways through the empty space in the rubber stopper, you can control the movement of the needle and liquid.
    • Ensure that you withdraw all the medication from the vial.

  • Hold the syringe with the gray needle pointing upwards and check that there are no air bubbles.
  • To remove air bubbles, gently tap the syringe until the air accumulates at the top. Then, slowly push the plunger until the bubbles disappear.
  • Do not touch the gray needle or allow the needle to touch any surface.
