Contents of the pack and other information
Ovitrelle contains a medicine called ‘choriogonadotropin alfa’, made in a laboratory by a special recombinant DNA technique. Choriogonadotropin alfa is similar to a hormone found naturally in your body called ‘chorionic gonadotropin’, which is involved in reproduction and fertility.
Ovitrelle is used together with other medicines:
To help develop and ripen several follicles (each containing an egg) in women undergoing assisted reproductive technologies (procedure that may help you to become pregnant) such as ‘in vitro fertilisation’. Other medicines will be given first to bring about the growth of several follicles.
To help release an egg from the ovary (ovulation induction) in women who cannot produce eggs (‘anovulation’), or women who produce too few eggs (‘oligo-ovulation’). Other medicines will be given first to develop and ripen the follicles.
if you are allergic to choriogonadotropin alfa or any of the other ingredients of this medicine (listed in section 6).
if you have a tumour in your hypothalamus or pituitary gland (both are parts of the brain).
if you have large ovaries or sacs of fluid within the ovaries (ovarian cysts) of unknown origin.
if you have unexplained vaginal bleeding.
if you have cancer of your ovaries, womb or breast.
if you have severe inflammation of your veins or blood clotting in your veins (active thromboembolic disorders).
if you have any condition that usually makes a normal pregnancy impossible, such as menopause or early menopause (ovarian failure), or malformations of sexual organs.
Do not use Ovitrelle if any of the above applies to you. If you are not sure, talk to your doctor before using this medicine.
Before the treatment is started, your and your partner's fertility should be evaluated by a doctor experienced in the treatment of fertility problems.
Ovarian hyperstimulation syndrome (OHSS)
This medicine may increase your risk of developing OHSS. This is when your follicles develop too much and become large cysts.
If you get lower abdominal pain, gain any weight rapidly, feel sick or are vomiting, or have difficulty in breathing, do not give yourself the Ovitrelle injection and talk to your doctor straight away (see section 4). If you are developing OHSS, you may be told not to have sex or to use a barrier contraceptive method for at least four days.
The risk of OHSS is reduced if the usual dose of Ovitrelle is used, and if you are monitored closely throughout your treatment cycle (e.g. blood tests for estradiol levels and ultrasound).
Multiple pregnancy and/or birth defects
When using Ovitrelle, you have a higher risk of being pregnant with more than one child at the same time (‘multiple pregnancy’, usually twins) than if you conceived naturally. Multiple pregnancy may lead to medical complications for you and your babies. When undergoing assisted reproductive technologies, the risk of having a multiple pregnancy is related to your age, the quality and the number of fertilised eggs or embryos placed inside you. Multiple pregnancies and specific characteristics of couples with fertility problems (e.g. age) may also be associated with an increased chance of birth defects.
The risk of multiple pregnancy is reduced if you are monitored closely throughout your treatment cycle (e.g. blood tests for estradiol levels and ultrasound).
Ectopic pregnancy
Pregnancy outside of the womb (an ectopic pregnancy) may occur in women with damaged fallopian tubes (the tubes which carry the egg from the ovary to the womb). Therefore, your doctor should perform an early ultrasound examination to rule out the possibility of pregnancy outside the womb.
Miscarriage
When undergoing assisted reproductive technologies or stimulation of your ovaries to produce eggs, you are more likely to have a miscarriage than the average woman.
Blood clotting problems (thromboembolic events)
Talk to your doctor before using Ovitrelle if you or a member of your family have ever had blood clots in the leg or in the lung, or a heart attack or stroke. You may be at a higher risk of serious blood clots or existing clots might become worse with Ovitrelle treatment.
Tumours of sexual organs
There have been reports of tumours in the ovaries and other sex organs, both benign and malignant, in women who have undergone multiple regimens for infertility treatment.
Pregnancy tests
If you do a pregnancy test with serum or urine after use of Ovitrelle, and up to ten days later, it may happen that you get a false positive test result. If you are not sure, talk to your doctor.

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.
Your doctor or nurse will show you how to use the Ovitrelle pre-filled syringe to inject the medicine.
Inject Ovitrelle as your doctor or nurse taught you.
After the injection, dispose of the used syringe safely.
If you administer Ovitrelle to yourself, please carefully read the following instructions:
Wash your hands. It is important that your hands and the items you use are as clean as possible.
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.
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.
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.
The effects of an overdose of Ovitrelle are unknown, nevertheless there is a possibility that ovarian hyperstimulation syndrome (OHSS) may occur, which is further described in section 4.
If you forget to use Ovitrelle, please talk to your doctor as soon as you notice.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Allergic reactions such as rash, fast or uneven pulse, swelling of your tongue and throat, sneezing, wheezing, or serious breathing difficulty are very rare (may affect up to 1 in 10,000 people).
Lower abdominal pain, abdominal distension or abdominal discomfort together with nausea (feeling sick) or vomiting may be the symptoms of ovarian hyperstimulation syndrome (OHSS). This may indicate that the ovaries over-reacted to the treatment and that large ovarian cysts developed (see also in section 2. under “Ovarian hyperstimulation syndrome”). This event is common (may affect up to 1 in 10 people).
The OHSS may become severe with clearly enlarged ovaries, decreased urine production, weight gain, difficulty in breathing and possible fluid accumulation in your stomach or chest. This event is uncommon (may affect up to 1 in 100 people).
Serious blood clotting complications (thromboembolic events) sometimes independent of OHSS may be found very rarely. This could cause chest pain, breathlessness, stroke or heart attack (see also in section 2. under “Blood clotting problems”).
Common (may affect up to 1 in 10 people)
Headache.
Local reactions at the injection site, such as pain, redness or swelling.
Uncommon (may affect up to 1 in 100 people)
Diarrhoea.
