PUREGON 600 IU/0.72 ML INJECTABLE SOLUTION

2. What you need to know before you use Puregon

Do not use Puregon

If:

• you are allergic to follitropin beta or any of the other ingredients of Puregon (listed in section 6)
• you have a tumor in the ovary, breast, uterus, testicles, or brain (pituitary gland or hypothalamus)
• you have heavy or irregular vaginal bleeding of unknown cause
• your ovaries do not work due to a disease called primary ovarian insufficiency
• you have ovarian cysts or enlargement of the ovaries that are not due to polycystic ovary syndrome (PCOS)
• you have malformations of the sex organs that make a normal pregnancy impossible
• you have uterine fibroids that make a normal pregnancy impossible
• you are an infertile man due to a disease called primary testicular insufficiency.

Warnings and precautions

Tell your doctor before you start using Puregon if:

• you have had an allergic reaction to certain antibiotics (neomycin and/or streptomycin)
• you have uncontrolled pituitary gland or hypothalamic problems
• you have underactive thyroid gland (hypothyroidism)
• your adrenal glands do not work properly (adrenal insufficiency)
• you have high levels of prolactin in your blood (hyperprolactinemia)
• you have any other disease (e.g., diabetes, heart disease, or any other long-term disease)

If you are a woman:

Ovarian Hyperstimulation Syndrome (OHSS)

Your doctor will regularly check the effects of treatment to choose the right dose of Puregon at each stage. You will have regular ultrasound scans of your ovaries. Your doctor may also check your hormone levels in your blood. This is very important because too high a dose of FSH can lead to rare but serious complications, in which the ovaries become overstimulated and the growing follicles become larger than normal. This disease is serious and is called Ovarian Hyperstimulation Syndrome (OHSS). In rare cases, severe OHSS can be life-threatening. OHSS causes fluid to build up suddenly in your stomach and chest, which can cause blood clots. Contact your doctor immediately if you feel severe abdominal swelling, stomach pain, nausea, vomiting, sudden weight gain due to fluid buildup, diarrhea, decreased urine output, or difficulty breathing (see also section 4, Possible side effects).

? Regular monitoring of your response to FSH treatment helps prevent ovarian overstimulation. Contact your doctor immediately if you feel stomach pain, and also if it occurs a few days after the last injection.

Multiple Pregnancy or Birth Defects

After treatment with gonadotropins, there is a higher chance of multiple pregnancies, even when only one embryo is transferred to the uterus. Multiple pregnancies pose a higher risk to the health of both the mother and the children before and after birth. Additionally, multiple pregnancy and the characteristics of patients undergoing fertility treatment (e.g., woman's age, semen characteristics, genetic history of both parents) may be associated with a higher risk of birth defects.

Pregnancy Complications

The risk of an ectopic pregnancy (a pregnancy outside the uterus) is slightly higher. Therefore, your doctor should perform an ultrasound at the beginning to rule out the possibility of an ectopic pregnancy.

In women undergoing fertility treatment, there is a slightly higher risk of miscarriage.

Blood Clots (Thrombosis)

Treatment with Puregon, like pregnancy itself, can increase the risk of blood clots (thrombosis). Thrombosis is the formation of a blood clot in a blood vessel.

Blood clots can cause serious diseases, such as:

• blockage in your lungs (pulmonary embolism)
• stroke
• heart attack
• blood vessel problems (thrombophlebitis)
• lack of blood flow (deep vein thrombosis), which can cause the loss of your arm or leg.

Discuss this with your doctor before starting treatment, especially in the following cases:

Ovarian Torsion

Torsion can occur after treatment with gonadotropins, including Puregon. Ovarian torsion is the twisting of an ovary. The twisting of the ovary could cut off blood flow to the ovary.

Before you start using this medicine, tell your doctor if:

• you have had Ovarian Hyperstimulation Syndrome (OHSS) before
• you are pregnant or think you might be
• you have had abdominal surgery
• you have had ovarian torsion before
• you have had or have ovarian cysts.

Ovarian Tumors and Other Reproductive System Tumors

There have been reports of ovarian tumors and other reproductive system tumors in women who have undergone fertility treatment. It is not known if treatment with fertility medications increases the risk of these tumors in infertile women.

Other Diseases

Additionally, before you start using this medicine, tell your doctor if:

• your doctor has told you that pregnancy could be dangerous for you.

If you are a man:

Men with High FSH Levels in Their Blood

High FSH levels in the blood are a sign of testicular damage. In such cases, Puregon is usually not effective. To monitor the effects of treatment, your doctor may ask for a semen sample to analyze, 4 to 6 months after starting treatment.

Children and Adolescents

Puregon should not be used in children and adolescents.

Using Puregon with Other Medicines

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

If Puregon is given with clomiphene citrate, the effect of Puregon may increase. If a GnRH agonist (a medicine to prevent early ovulation) has been given, higher doses of Puregon may be needed.

Pregnancy and Breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine. You should not use Puregon if you are already pregnant or think you might be.

Puregon may affect milk production. It is unlikely that Puregon will pass into breast milk. If you are breast-feeding, ask your doctor for advice before using Puregon.

Driving and Using Machines

Puregon is unlikely to affect your ability to drive or use machines.

Puregon Contains Benzyl Alcohol

This medicine contains 10 mg of benzyl alcohol per ml.

Benzyl alcohol may cause allergic reactions.

Ask your doctor or pharmacist for advice if you have liver or kidney disease. This is because large amounts of benzyl alcohol can build up in your body and cause side effects (metabolic acidosis).

Ask your doctor or pharmacist for advice if you are pregnant or breast-feeding. This is because large amounts of benzyl alcohol can build up in your body and cause side effects (metabolic acidosis).

Puregon Contains Sodium

This medicine contains less than 1 mmol of sodium (23 mg) per injectable; i.e., it is essentially "sodium-free".

3. How to Use Puregon

Follow the instructions for administration of this medicine exactly as told by your doctor. If you are not sure, ask your doctor or pharmacist again.

Dosing in Women

Your doctor will decide the initial dose. This dose may be adjusted as your treatment progresses. More details on the dosing schedule are provided below.

There are large variations in ovarian response to FSH among women, making it impossible to establish a suitable dosing schedule for all patients. To find the correct dosage, your doctor will monitor follicle growth with ultrasound and measure estradiol (female sex hormone) levels in your blood.

• Women who do not ovulateYour doctor will set an initial dose that is maintained for at least 7 days. If no ovarian response is detected, the daily dose is gradually increased until follicle growth and/or estradiol levels indicate an appropriate response, and this daily dose is maintained until a follicle of the appropriate size is detected. Normally, 7 to 14 days of treatment are sufficient. Puregon treatment is then stopped, and ovulation is induced with human chorionic gonadotropin (hCG).
• Assisted reproduction programs, such as in vitro fertilizationYour doctor will set an initial dose that is maintained for the first 4 days, at a minimum. Your dose may then be adjusted based on your ovarian response. When a sufficient number of follicles of the appropriate size are detected, the final stage of follicular maturation is induced with hCG. Egg retrieval is performed 34-35 hours later.

Dosing in Men

Puregon is usually prescribed at a dose of 450 UI per week, almost always in three injections of 150 UI, along with another hormone (hCG), for at least 3 to 4 months. The treatment period is the same as the time needed for sperm development and the expected time for improvement. If your sperm production has not started after this period, your treatment may continue for at least 18 months.

How to Administer the Injection

Puregon solution for injection in cartridges has been developed for use with the Puregon Pen injector. The instructions for using the injector, which are provided separately, must be followed carefully. Do not use the cartridge if the solution contains particles or is not transparent.

With the injector, injections under the skin (e.g., in the lower abdomen) can be administered by you or your partner. Your doctor will tell you when and how to do this. If you inject Puregon yourself, follow the instructions carefully to administer Puregon correctly and with minimal discomfort.

The first injection of Puregon should only be administered in the presence of a doctor or nurse.

It is possible that a small amount of medicine will remain in the cartridge after completing treatment with Puregon, even when all doses have been administered correctly. Do not attempt to use the remaining medicine. After administration of the last dose, the cartridge should be disposed of properly.

If You Use More Puregon than You Should

Tell your doctor immediately.

Taking too high a dose of Puregon can cause excessive stimulation of the ovaries (OHSS), which can manifest as stomach pain. If you feel unwell due to stomach pain, tell your doctor immediately. See also section 4, Possible side effects.

If You Forget to Use Puregon

If you miss a dose, do not take a double dose to make up for the missed doses.

? Contact your doctor.

If you have any further questions on the use of this medicine, ask your doctor.

4. Possible Adverse Effects

Like all medicines, this medicine can cause adverse effects, although not all people suffer from them.

Inform your doctor immediately if you notice:

Signs of a severe allergic reaction (anaphylactic reaction), such as swelling of the face, lips, throat, or tongue that causes difficulty swallowing or breathing, shortness of breath, feeling of loss of consciousness.

Severe Adverse Effects in Women

A complication of FSH is ovarian hyperstimulation. Ovarian overstimulation can trigger a disease called Ovarian Hyperstimulation Syndrome (OHSS), which can be a serious clinical problem. The risk of this occurring can be reduced by carefully controlling follicle development during treatment. Your doctor will perform ultrasound scans of your ovaries to carefully monitor the number of mature follicles. Your doctor may also check hormone levels in your blood. The first symptoms are stomach pain, discomfort, or diarrhea. In more severe cases, you may experience enlargement of the ovaries, fluid accumulation in the abdomen and/or chest, (which can cause sudden weight gain due to fluid accumulation) or the formation of blood clots in the circulatory system. See section 2 Warnings and Precautions.

If you experience stomach pain or any of these symptoms of ovarian hyperstimulation, contact your doctor immediately, even if they occur several days after the last injection.
