What Ovidrel is used for

Ovidrel belongs to a family of hormones known as gonadotrophins, which are involved in the normal control of reproduction.

The active substance of Ovidrel is choriogonadotropin alfa that is produced in mammalian cells modified by recombinant DNA technology.

Ovidrel 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. Follicles are the structures in your ovaries that contain the egg. Ovidrel is then used to ripen (mature) these follicles.

Ovidrel is also used in women who do not produce eggs (anovulation), or who produce too few eggs (oligo-ovulation). It is used to trigger the release of eggs (ovulation), after other medicines have been used to develop the follicles.

Your doctor may prescribe Ovidrel for another reason. Ask your doctor if you have any questions about why Ovidrel has been prescribed for you.

Ovidrel is not addictive.

This medicine is available only with a doctor's prescription.

Before you use Ovidrel

When you must not use it

Do not use Ovidrel if:

  • you have a history of allergy to choriogonadotropin alfa, or a similar medicine, or any other inactive ingredients (listed at the end of this leaflet).
    Symptoms of an allergic reaction to Ovidrel may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Do not take Ovidrel if you have, or have had, any of the following medical conditions:

  • your ovaries are unable to be stimulated to produce eggs (primary ovarian failure or premature menopause)
  • uncontrolled thyroid or adrenal gland disease
  • a tumour of the hypothalamus or pituitary gland
  • ovarian enlargement or one or more large ovarian cysts
  • cancer of your ovaries, uterus (womb) or breasts
  • fibroid tumours in your uterus which would make pregnancy impossible
  • if you have been through menopause

Ovidrel should not be used in the elderly or in children.

Do not take Ovidrel after the expiry date printed on the pack. Do not take Ovidrel if the packaging is torn or shows signs of tampering. If your medicine has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start using Ovidrel, contact your doctor.

Before you start to use it

  • Your doctor will assess you and your partner's infertility. This may include tests for other medical conditions, which may interfere with your ability to become pregnant. If necessary, other medical conditions may be treated before starting infertility treatments and Ovidrel.

Tell your doctor if you have or have had any other pre-existing medical conditions. Treatment with Ovidrel may increase your risk of developing a condition called ovarian hyperstimulation syndrome (OHSS). This is when the ovaries over react to the hormonal treatment and develop too many follicles. The most common symptom is stomach pain. During stimulation your doctor will monitor your treatment by use of ultrasound and blood tests to measure oestrogen levels. This will help to indicate if you are likely to develop OHSS. If necessary, your doctor will delay or cancel your Ovidrel injection.

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

There may be a slightly increased risk of birth defects in women using assisted reproductive technologies. This may be due to maternal age, genetic factors, multiple pregnancies or the assisted reproductive technologies. Talk to your doctor about any concerns you may have before undergoing treatment.

Tell your doctor if you or your family have or have had increased risk of developing blood clots e.g. stroke, heart attacks.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without prescription from your pharmacy, supermarket or health food shop.

Ovidrel may interfere with the results of a blood or urinary hCG (pregnancy) test for up to 10 days. This may lead to a false positive pregnancy test.
