Consumer Medicine Information

This leaflet answers some common questions about PUREGON.

It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you using PUREGON against the benefits they expect it will have for you.

If you have any concerns about using this medicine, ask your doctor or pharmacist.

Keep this information with your medicine. You may wish to read it again.

 

PUREGON solution for injection contains follitropin beta, a hormone known as follicle stimulating hormone (FSH).

FSH belongs to the group of gonadotrophins, which play an important role in human fertility and reproduction. FSH is needed in women for the growth and development of follicles in the ovaries. Follicles are small round sacs that contain the egg cells.

In men, FSH is needed for the production of sperm.

PUREGON is used to treat infertility in any of the following situations:

 

Women:

PUREGON can be used to cause ovulation in women who have not responded to treatment with clomiphene citrate.

PUREGON can be used to bring about the development of multiple follicles in women undergoing assisted reproduction technologies (ART) such as in vitro fertilisation (IVF).

Men:

PUREGON can be used for the production of sperm in men who are infertile due to a hormonal deficiency.

PUREGON is not addictive.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Do not use PUREGON if you:

are allergic (hypersensitive) to follitropin beta or to any of the ingredients in PUREGON listed at the end of this leaflet

have a tumour of the ovary, breast, uterus, testis, or brain (pituitary gland or hypothalamus)

are pregnant or think you may be pregnant

are breast feeding

have heavy or irregular vaginal bleeding where the cause is not known

suffer from primary ovarian failure

have ovarian cysts or enlarged ovaries not caused by polycystic ovarian disease (PCOD)

have malformations of the sexual organs which make a normal pregnancy impossible

have fibroid tumours in the uterus which make a normal pregnancy impossible

suffer from primary testicular failure.

Tell your doctor if you:

have experienced an allergic reaction to neomycin and/or streptomycin (antibiotics) in the past. PUREGON may contain traces of these antibiotics

have ever had ovarian hyperstimulation syndrome (OHSS)

are pregnant or think that you may be pregnant

have ever had stomach (abdominal) surgery

have ever had a twisting of an ovary

have past or current cysts in your ovary or ovaries

you have uncontrolled pituitary gland or hypothalamic problems

have an underactive thyroid gland (hypothyroidism)

have adrenal glands that are not working properly (adrenocortical insufficiency)

have high prolactin levels in the blood (hyperprolactinemia)

have been told by a doctor that pregnancy would be dangerous for you

have any other medical conditions (for example, diabetes, heart disease, or any other long-term disease).

In Women

Close supervision by your doctor is very important. Usually ultrasound scans of the ovaries are regularly made. Your doctor may also check blood hormone levels. The results of these tests allow your doctor to choose the correct dose of PUREGON from day to day. This is very important since too high a dose of FSH may lead to rare but serious complications in which the ovaries are overly stimulated and the growing follicles become larger than normal.

This serious medical condition is called ovarian hyperstimulation syndrome (OHSS).

In rare cases, severe OHSS may be life-threatening. OHSS causes fluid to build up suddenly in your stomach and chest areas and can cause blood clots to form.

Call your doctor right away if you have:

severe abdominal swelling

pain in the stomach (abdomen), even if this occurs dome days after the last injection has been given

nausea (feeling sick)

vomiting

sudden weight gain

diarrhoea

decreased urine output

trouble breathing.

Regular monitoring of the response to FSH-treatment helps to prevent ovarian overstimulation.

Ovarian Torsion

Ovarian torsion has occurred after treatment with gonadotrophins including PUREGON. Ovarian torsion is the twisting of an ovary. Twisting of the ovary could cause the blood flow to the ovary to be cut off.

Before starting this medicine it is important to inform your doctor if you:

have ever had ovarian hyperstimulation syndrome (OHSS)

are pregnant or think that you may be pregnant

have ever had stomach (abdominal) surgery

have ever had a twisting of an ovary

have past or current cysts in your ovary or ovaries

Treatment with PUREGON (like pregnancy itself) may increase the risk of having a blood clot (thrombosis). Thrombosis is the formation of a blood clot in a blood vessel.

Blood clots can lead to serious medical conditions, such as:

blockage in your lungs (pulmonary embolus)

stroke

heart attack

blood vessel problems (thrombophlebitis)

a lack of blood flow (deep venous thrombosis) that may result in a loss of your arm or leg.

Please discuss this with your doctor, before starting treatment, especially if:

you already know you have an increased risk of thrombosis

you, or anyone in your immediate family, have ever had a thrombosis

you are severely overweight.

Ovarian and other reproductive system tumours

There have been reports of ovarian and other reproductive system tumours in women who have had infertility treatment. It is not known if treatment with fertility medicines increases the risk of these tumours in infertile women.

Other medical conditions

You have been told by a doctor that pregnancy would be dangerous for you.

In Men

Elevated FSH blood levels are indicative of testicular damage. PUREGON is usually not as effective in such cases. To monitor your treatment, your doctor may ask you for a semen analysis to be performed 4 to 6 months after the beginning of treatment.

Do not use PUREGON if the packaging is torn or shows signs of tampering.

Do not use PUREGON after the expiry date printed on the pack has passed.

If it has expired or is damaged, return it to your pharmacist or clinic for disposal.

Talk to your doctor if you are not too sure about using PUREGON.

You and your partner’s fertility should be assessed to see if PUREGON is appropriate for you.

Tell your doctor if you are breastfeeding or intend to breastfeed.

Tell your doctor if you have allergies to any other medicines, foods or preservatives.

Tell your doctor if you have or have had any of the following medical conditions:

thyroid disorder

adrenal gland disorder

ovarian cyst

cancer or a tumour of the breast, ovary, uterus, prostate, hypothalamus or pituitary gland

polycystic ovarian disease (irregular or no periods, acne, obesity, excess hair growth)

unexplained vaginal bleeding.

If you have any of the above conditions, tell your doctor before you start to use PUREGON.

Tell your doctor if you have or have had any other medical conditions.

Pregnancy:

After treatment with gonadotrophic preparations, there is an increased risk of having multiple pregnancies, even when only one embryo is transferred into the uterus. Multiple pregnancies carry an increased health risk for both the mother and her babies around the time of birth.

Furthermore, multiple pregnancies and characteristics of the patients undergoing fertility treatment (e.g age of the female, sperm characteristics, genetic background of both parents) may be associated with an increased risk of birth defects.

Generally in women undergoing fertility treatment there may be a slightly higher risk of miscarriage.

There is a slightly increased risk of a pregnancy outside of the uterus (an ectopic pregnancy). Therefore, your doctor should perform an early ultrasound examination to exclude the possibility of pregnancy outside the uterus.

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

The very first injection of PUREGON should be given by a health professional.

PUREGON solution for injection in cartridges has been developed for use in the PUREGON Pen. The separate instructions for using the pen must be followed carefully. Do not use the cartridge if the solution contains particles or if the solution is not clear.

Using the pen, injections just under the skin (in the stomach or thigh) can be given by you or your partner. Your doctor will tell you when and how to do this. When the instructions are followed carefully, PUREGON will be administered properly and with minimal discomfort.

Your doctor will decide on the dose of PUREGON to be given. This dose may be adjusted as your treatment progresses.

There are large differences between women in the response of the ovaries to FSH. This makes it impossible to set a dosage schedule which is suitable for all patients. To find the right dosage, follicle growth is checked by means of ultrasound scanning and measurement of the amount of oestradiol (female sex hormone) in the blood.

The following is a guide to the usual dose:

Women who are not ovulating

The dose usually starts at 75-150 IU daily. The dose is continued for at least 5 to 7 days. If there is no response, the daily dose will be gradually increased until an adequate response is obtained. The daily dose is then maintained until a follicle of adequate size is present.

An hCG injection (to stimulate ovulation) is given after the last PUREGON injection.

Women undergoing assisted reproductive technologies

The dose usually starts at 75 to 300 IU daily. The dose may be adjusted according to your response. When a sufficient number of follicles of adequate size are present, the final phase of maturation of the follicles is induced by administration of hCG. Oocyte (egg) retrieval is performed 34-35 hours later. 

Men

PUREGON is usually prescribed at a dose of 75 IU daily or 2-3 times a week, in combination with another hormone (hCG) for at least 3 months.

If you forget an injection or are not sure what to do, contact your doctor or nurse immediately for advice. Do not double the dose on any day.

Immediately contact your doctor, or for Australia, the Poisons Information Centre (telephone 13 11 26), or for New Zealand, National Poisons Centre (telephone 0800 POISON or 0800 764 766) for advice.

In females, too high a dose may cause overstimulation of the ovaries (Ovarian Hyperstimulation Syndrome, OHSS) (see Side Effects).

See your doctor regularly so you can be monitored closely throughout your treatment.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking PUREGON.

If you plan to have surgery, tell your doctor or dentist that you are using PUREGON.

Tell all doctors and dentists who are treating you that you are using PUREGON.

Be careful driving or operating machinery until you know how PUREGON affects you.

As far as is known, PUREGON has no effect on alertness and concentration.

Do not stop using PUREGON without telling your doctor.

Do not change the dose unless your doctor tells you to.

Changing your dose without telling your doctor can increase your risk of unwanted side effects or can prevent the drug from working properly.

Do not give your medicine to anyone else, even if they have the same condition as you.

Tell your doctor as soon as possible if you do not feel well while you are using PUREGON. All medicines can have side effects. Sometimes they are serious, most of the time they are not.
