Patient information leaflet

What is it and what is it used for?

Ovitrelle is a medicinal product containing choriogonadotropin alfa, which is very similar to chorionic gonadotrophin found naturally in humans, but it is made in laboratories by special recombinant DNA techniques. It belongs to the family of hormones called gonadotrophins, which are involved in the normal control of reproduction.

Ovitrelle is used in women undergoing assisted reproductive techniques such as in vitro fertilisation (IVF). Other medicines are given first to bring about the growth and development of several follicles, to produce eggs. Ovitrelle is then used to ripen (mature) these follicles.

Ovitrelle is also used in women who do not produce eggs (a condition called anovulation), or who produce too few eggs (oligo-ovulation). It is given to bring about the release of eggs (ovulation), after other medicines have been used to develop the follicles.

What should you consider before use?

You and your partner's fertility should be evaluated before the treatment is started.

Do not take Ovitrelle:
  • If you are pregnant or breast-feeding
  • If you have ovarian enlargement or one or more large ovarian cysts
  • If you have unexplained vaginal bleeding
  • If you have been diagnosed as having ovarian, uterine or breast cancer
  • If you have had a tumour of the hypothalamus or pituitary gland
  • If you suffer from severe inflammation of the veins or blood clotting in the veins (active thrombo-embolic disorders)
  • If you are allergic (hypersensitive) to choriogonadotropin or any of the ingredients of Ovitrelle
  • If you have any condition which would make a normal pregnancy impossible (e.g. absent uterus, ovaries which have not developed properly, fibroids) or you have been through the menopause
  • If you have had an extrauterine pregnancy within the last 3 months
Take special care with Ovitrelle:

Treatment with Ovitrelle may increase your risk of developing a condition called ovarian hyperstimulation syndrome (OHSS) (see also ?Possible side effects?). This is when the ovaries over-react to the treatment and develop too many follicles. The most common symptom is abdominal pain.

If you have significant abdominal pain or discomfort, do not give yourself the injection, and speak to your doctor or nurse as soon as possible. You should not have intercourse for at least 4 days, or otherwise you should use a barrier method for contraception.

Compared with natural conception, the frequency of multiple pregnancies and births is increased in patients receiving this treatment. The majority of these are twins. In assisted conception techniques, the number of babies is related to the number of embryos replaced.

Your risk of OHSS or multiple pregnancy is reduced if the usual dose of Ovitrelle is used, and you are monitored closely throughout your treatment cycle (e.g. blood tests for estradiol levels and ultrasound).

Using other medicines:

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Pregnancy and breast-feeding

You should not take Ovitrelle if you are pregnant or breast-feeding.

How is it used?

Always take Ovitrelle exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure
The usual dose of Ovitrelle is 1 pre-filled syringe (250 micrograms/0.5 ml) given as a single injection. Your doctor will have explained exactly when to give the injection.

Ovitrelle is intended for subcutaneous use, that means given by injection under the skin. Each pre-filled syringe is for single use only, only clear solution without particles should be used.

Sometimes the injection will be given to you by a doctor or nurse, or you or your partner may be trained to give the injection at home.

If you administer Ovitrelle to yourself, please carefully read the following instructions:

1. Wash your hands. It is important that your hands and the items you use are as clean as possible.

2. Assemble everything you need. Please note that alcohol swabs are not contained in the package. Find a clean area and lay out everything:

  • two alcohol swabs,
  • one pre-filled syringe containing the medicinal product

3. Injection: Immediately inject the solution: Your doctor or nurse will have already advised you where to inject (e.g. tummy, front of thigh). Wipe the chosen area with an alcohol swab. Firmly pinch the skin together and insert the needle for injection at a 45° to 90° angle using a dart-like motion. Inject under the skin, as you were taught. Do not inject directly into a vein. Inject the solution by pushing gently on the plunger. Take as much time as you need to inject all the solution. Immediately withdraw the needle and clean the skin with an alcohol swab using a circular motion.

4. Dispose of all used items: Once you have finished your injection, immediately discard the empty syringe in a sharps container. Any unused solution must be discarded.

If you use more Ovitrelle than you should

If too much Ovitrelle is used, there is a possibility that ovarian hyperstimulation syndrome may occur, which is further described under ?Take special care with Ovitrelle? and ?Possible side effects'. You should consult your doctor if symptoms of this syndrome occur.

If you forget to take Ovitrelle

You should contact your doctor.

What are possible side effects?

Like all medicines, Ovitrelle can cause side effects, although not everybody gets them. The majority of side effects seen to date have been mild or moderate. The most frequent side effects reported have been tiredness, pain and local reactions at the site of injection.

Ovarian hyperstimulation syndrome has been observed in approximately 4% of the patients in clinical trials; most of these cases were mild or moderate in nature. Blood in the peritoneal cavity, respiratory difficulties are possible complications of ovarian hyperstimulation syndrome.

This syndrome is characterized by large ovarian cysts. First symptoms of ovarian hyperstimulation are pain in the lower abdominal region, possibly in combination with nausea, vomiting and weight gain. Should the above mentioned symptoms occur, a careful medical examination is indicated as soon as possible.

Common side effects reported include abdominal pain, nausea and vomiting, headache, injection site inflammation and reaction, dizziness. Diarrhoea, depression, irritability, restlessness and breast pain have also been reported in some cases and are considered uncommon.

Extrauterine pregnancy, ovarian torsion (a condition affecting the ovaries) and other complications may arise from the assisted conception techniques your doctor may use.

Isolated cases of mild allergic reactions to Ovitrelle (rash) have been reported.

If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist.

How should it be stored?
