What it is and what it is used for

for

The active ingredient in Decapeptyl SR 11.25 mg is triptorelin. Triptorelin belongs to a group of medicines called gonadotropin releasing hormone (GnRH) agonists. Triptorelin is similar to the gonadotropin releasing hormone which occurs naturally in your body. In men, triptorelin lowers the levels of the hormone testosterone. In women, it reduces oestrogen levels. Decapeptyl SR 11.25 mg has three different uses. It is used in men, women and children to treat completely different conditions. Decapeptyl SR is available in two other strengths: Decapeptyl SR 3 mg is used once a month and Decapeptyl SR 22.5 mg is used once every 6 months. Not all dose strengths are approved for all indications. Ask your doctor if you would like to discuss changing your treatment. This leaflet gives information for all three uses of Decapeptyl SR 11.25 mg. Please read all the sections that are about you and your condition. MEN In men, Decapeptyl SR 11.25 mg is used to treat prostate cancer. WOMEN In women, Decapeptyl SR 11.25 mg is used to treat Endometriosis – a condition in which the tissue that normally lines the uterus (endometrium) grows in other places.

CHILDREN In children, Decapeptyl SR 11.25 mg is used to treat puberty that occurs at a very young age, i.e. before 8 years in girls and 10 years in boys (Central Precocious Puberty). This is called 'early puberty' in the rest of this leaflet.

What you need to know before you take it

e Decapeptyl SR 11.25 mg

MEN Do not use Decapeptyl SR 11.25 mg:

  • If you are allergic to triptorelin or similar types of drugs (other GnRH agonists) or any of the other ingredients of this medicine (listed in section 6). Warnings and precautions: Talk to your doctor or pharmacist before taking Decapeptyl SR 11.25 mg.
  • Patients taking GnRH analogues have reported depression. Sometimes depression can be severe and in rare cases lead to suicidal thoughts. These reports include cases where symptoms improved or stopped after the treatment was discontinued. Suicidal thoughts have mostly been reported in patients with a previous history of depression. If you are taking Decapeptyl SR 11.25 mg and subsequently develop depressed mood, worsening depression, or suicidal thoughts inform your doctor as soon as possible. Your doctor may want to monitor your depression during treatment.
  • If you are using medicines for delaying your normal blood clotting, you may experience bruising at the site of the intramuscular injection.
  • In adults, triptorelin may cause thinning of the bones (osteoporosis) with an increased risk of bone fractures. You should therefore tell your doctor if you have any of the below risk factors as he/she might give you bisphosphonate (drugs used to treat wark bones) to treat bone loss. Risk factors may include: o If you or any of your close family have thinning of the bones. o If you drink excessive amounts of alcohol, and/or smoke heavily. o If you take medicines over a long period of time that may cause thinning of the bones, for example medicines for epilepsy or steroids (such as hydrocortisone or prednisolone).
  • If any convulsions occur, inform immediately your doctor. There have been reports of convulsions in patients receiving triptorelin or similar medicines. These occurred in patients with or without medical history of epilepsy.
  • When you first start treatment with Decapeptyl SR 11.25 mg it actually increases the level of your hormones for a short time. This means that you may feel worse to begin with (see section 4 'Possible side effects' for more information). The doctor may give you some medicine (an anti-androgen) to prevent your symptoms from getting worse. After a short time, the amount of hormone will drop, and your symptoms will get better. If you suffer from urinary obstruction or spinal cord (nerves in your backbone) compression due to your prostate cancer spreading, your doctor will supervise you closely for the first few weeks of treatment. If you experience difficulty passing urine, bone pain, weakness of lower limbs or pins and needles sensation, contact your doctor immediately, who will assess and treat you appropriately.
  • Tell your doctor if you have diabetes.
  • Tell your doctor if you have any heart or blood vessel conditions, including heart rhythm problems (arrhythmia), or are being treated with medicines for these conditions. The risk of heart rhythm problems may be increased when using Decapeptyl SR 11.25 mg.

If you have an enlargement (benign tumour) of the pituitary gland that you were unaware of, this may be discovered during treatment. Symptoms include sudden headache, problems with eyesight and paralysis of the eye muscles. After surgical castration triptorelin does not induce any further decrease in serum testosterone levels. Diagnostic tests of pituitary gonadal function or sex organs conducted during treatment or after discontinuation of therapy with Decapeptyl SR 11.25 mg may be misleading. Testosterone decreasing agents may cause changes in ECG associated with heart rhythm abnormalities (QT prolongation). Tell your doctor if you have back pain, weakness, numbness or tingling in your legs. Treatment with GnRH analogues including Decapeptyl SR 11.25mg might increase the risk of anaemia (defined as a decrease in the count of red blood cells).

Your doctor may give you another drug to help you feel better during this time. Other medicines and Decapeptyl SR 11.25 mg: Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Decapeptyl SR 11.25 mg might interfere with some medicines used to treat heart rhythm problems (e.g. quinidine, procainamide, amiodarone and sotalol) or might increase the risk of heart rhythm problems when used with some other drugs (e.g. methadone (used for pain relief and part of drug addiction detoxification), moxifloxacin (an antibiotic), antipsychotics used for serious mental illnesses). Drugs which increase the level of a hormone called prolactin may react with Decapeptyl SR 11.25 mg. Many different kinds of drugs may increase prolactin levels. Driving and using machines: You may feel dizzy, tired or have problems with your sight such as blurred vision. These are possible side effects of treatment or from the underlying disease. If you experience any of these side effects, you should not drive or use machines. Decapeptyl SR 11.25 mg contains sodium This medicine contains less than 1 mmol (23 mg) sodium per dose, that is to say essentially 'sodium-free '. This medicine contains 2 mg of polysorbate 80 in each vial. Polysorbates may cause allergic reactions. Tell your doctor if you or your child have any know allergies. WOMEN Do not use Decapeptyl SR 11.25 mg:

  • If you are allergic to triptorelin or similar types of drugs (other GnRH agonists) or any of the other ingredients of this medicine (listed in section 6).
  • If you are pregnant or breast-feeding. Warnings and precautions: Talk to your doctor or pharmacist before taking Decapeptyl SR 11.25 mg.
  • Due to lack of clinical experience in women under 18 years of age, Triptorelin is not recommended in adolescent and young women as it might cause thinning of bone.
  • Patients taking GnRH analogues have reported depression. Sometimes depression can be severe and in rare cases lead to suicidal thoughts. These reports include cases where symptoms improved or stopped

If you have an enlargement (benign tumour) of the pituitary gland that you were unaware of, this may be discovered during treatment. Symptoms include sudden headache, problems with eyesight and paralysis of the eye muscles. You may have some vaginal bleeding in the first month of treatment. After that your periods normally stop. Tell your doctor if you have bleeding after the first month of treatment. Your periods should start approximately 5 months after the last injection.

You must use some form of contraception other than the 'pill' while you are having treatment and until you start your next period. Your doctor may suggest using a barrier method of contraception such as a condom or diaphragm (cap). Other medicines and Decapeptyl SR 11.25 mg: Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Drugs which increase the level of a hormone called prolactin may react with Decapeptyl SR 11.25 mg. Many different kinds of drugs may increase prolactin levels.

The following information is intended for medical or healthcare professionals only: INSTRUCTIONS FOR RECONSTITUTION 1. PREPARATION OF THE PATIENT BEFORE RECONSTITUTION •

Prepare the patient by disinfecting the injection site. This operation needs to be performed first because once reconstituted, the drug should be injected immediately.

2. PREPARATION OF THE INJECTION Two needles are provided in the box :

  • Needle 1 : a 20G needle (38 mm of length) without safety device to be used for reconstitution
  • Needle 2 : a 20G needle (38 mm of length) with safety device to be used for injection

The presence of bubbles on top of the lyophilisate is a normal appearance of the product. The following steps must be completed in a continuous sequence. 2a

  • Take out the ampoule containing the solvent. Tap any solution within the tip of the ampoule back to the main body of the ampoule.
  • Screw Needle 1 (without safety device) on to the syringe. Do not remove the needle protection yet.
  • Break open the ampoule with dot face up.
  • Remove the needle protection from Needle 1. Insert the needle in the ampoule and draw up all the solvent into the syringe.
  • Put aside the syringe containing the solvent. 2b
  • Take out the vial containing the powder. Tap any powder which has accumulated at the top of the vial back to the bottom of the vial.
  • Remove the plastic tab on top of the vial.
  • Take back the syringe containing the solvent, and insert the needle through the rubber stopper vertically into the vial. Inject the solvent slowly, so that, if possible, it washes down the entire upper part of the vial.

Page 11 of 13

2c

  • Pull up Needle 1 above the liquid level. Do not remove the needle from the vial. Reconstitute the suspension, by swirling gently from side to side. Do not invert the vial.
  • Continue swirling long enough (at least 30 seconds) to obtain a homogeneous and milky suspension.
  • Important: Check there is no unsuspended powder in the vial (if any powder clumps are present, continue swirling until they disappear). 2d
  • When the suspension is homogeneous, pull down the needle and without inverting the vial, draw up all of the suspension. A small amount will remain in the vial and should be discarded. An overfill is included to allow for this loss.
  • Grasp the coloured hub to disconnect the needle. Remove Needle 1 used for the reconstitution from the syringe. Screw on to the syringe Needle 2.
  • Move the safety sheath away from the needle and towards the syringe barrel. The safety sheath remains in the position you set.
  • Remove the needle protection from the needle.
  • Prime the needle to remove air from the syringe and inject immediately. 3. INTRAMUSCULAR INJECTION
  • To avoid sedimentation, inject immediately into the disinfected area as quickly as possible (within 1 minute from reconstitution).

4. AFTER USE • •

Activation of the safety system using a one-handed technique. Note: Keep your finger behind the tab at all times.

There are two alternatives to activate the safety system: • Method A : push the tab forward with your finger

Page 12 of 13

or •

Method B : push the sheath to a flat surface

•

In both cases press down with a firm quick motion until a distinct audible click is heard.

•

Visually confirm that the needle is fully engaged under the lock.

•

Used needles, any unused suspension or other waste materials should be disposed of in accordance with local requirements.

In patients treated with GnRH analogues for metastatic prostate cancer, treatment is usually continued upon development of castrate resistant prostate cancer.

Reference should be made to relevant guidelines.

Endometriosis

One intramuscular injection should be administered every 3 months. The treatment must be initiated in the first five days of the menstrual cycle. Treatment duration depends on the initial severity of the endometriosis and the changes observed in the clinical features (functional and anatomical) during treatment. The maximum duration of treatment should be 6 months (two injections).

A further course of treatment with Decapeptyl SR 11.25 mg, or with other GnRH agonists, beyond 6 months should not be undertaken due to concerns about bone density losses. In patients treated with GnRH analogues for endometriosis, the addition of an add-back therapy (ABT - an estrogen and progestogen) has been shown to reduce bone mineral density loss and vasomotor symptoms. Therefore, if appropriate, ABT should be co-administered with GnRH analogue taking into account the risks and benefits of each treatment.

Decapeptyl is also available as a 1-month treatment (Decapeptyl SR 3 mg) for endometriosis.

Central precocious puberty (before 8 years in girls and 10 years in boys)

One intramuscular injection should be administered every 3 months.

The treatment of children with Decapeptyl SR 11.25 mg should be under the overall supervision of a paediatric endocrinologist or of a paediatrician or endocrinologist with expertise in the treatment of central precocious puberty.

Treatment should be stopped around the physiological age of puberty in boys and girls and should not be continued in girls with a bone maturation of 12 to 13 years. There are limited data available in boys relating to the optimum time to stop treatment based on bone age, however it is advised that treatment is stopped in boys with a bone maturation age of 13-14 years.

4.3. Contraindications

Hypersensitivity to GnRH (gonadotropin releasing hormone), its analogues or to any of the excipients listed in section 6.1 (see section 4.8 Undesirable effects).

Pregnancy and lactation.

4.4. Special warnings and precautions for use

The use of GnRH agonists may cause a reduction in bone mineral density. In men, preliminary data suggest that the use of a bisphosphonate in combination with a GnRH agonist may reduce bone mineral loss. No specific data is available for patients with established osteoporosis or with risk factors for osteoporosis (e.g. chronic alcohol abuse, smokers, long-term therapy with drugs that reduce bone mineral density, e.g. anticonvulsants or corticosteroids, family history of osteoporosis, malnutrition, e.g. anorexia nervosa). Particular caution is therefore necessary since reduction in bone mineral density is likely to be more detrimental in these patients. Treatment with Decapeptyl SR 11.25 mg should be considered on an individual basis and only be initiated if the benefits of treatment outweigh the risk following a very careful appraisal. Consideration should be given to additional measures in order to counteract loss of bone mineral density.

Rarely, treatment with GnRH agonists may reveal the presence of a previously unknown gonadotroph cell pituitary adenoma. These patients may present with a pituitary apoplexy characterised by sudden headache, vomiting, visual impairment and ophthalmoplegia.

In patients undergoing treatment with GnRH agonists, an increased risk of depression was reported (which may be severe and includes rare case reports of suicidal ideation from post-marketing experience, including reports of positive dechallenge and reversible symptoms, and with the majority of reports occurring in patients with a background history of depression). Patients should be informed accordingly to contact a doctor as soon as possible if worsening depression occurs, and if suicidal ideation develops and treated as appropriate if symptoms occur. Patients with known depression should be monitored closely during therapy.

Convulsions have been reported with GnRH analogues, particularly in women and children. Some of these patients had risk factors for seizures (such as a history of epilepsy, intracranial tumors or co-medication with drugs known to present a risk of seizure reactions). Convulsions have also been reported in patients in the absence of such risk factors.

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially 'sodium-free'.

This medicine contains 2 mg of polysorbate 80 in each vial. Polysorbates may cause allergic reactions.

In men

Prostate cancer

Initially, Decapeptyl SR 11.25 mg, like other GnRH agonists, causes a transient increase in serum testosterone levels. As a consequence, isolated cases of transient worsening of signs and symptoms of prostate cancer may occasionally develop during the first weeks of treatment. During the initial phase of treatment, consideration should be given to the additional administration of a suitable anti-androgen to counteract the initial rise in serum testosterone levels and the worsening of clinical symptoms.

A small number of patients may experience a temporary worsening of signs and symptoms of their prostate cancer (tumour flare) and temporary increase in cancer related pain (metastatic pain), which can be managed symptomatically.

As with other GnRH agonists, isolated cases of spinal cord compression or urethral obstruction have been observed. If spinal cord compression or renal impairment develops, standard treatment of these complications should be instituted, and in extreme cases an immediate orchidectomy (surgical castration) should be considered. Careful monitoring is indicated during the first weeks of treatment, particularly in patients suffering from vertebral metastasis, at the risk of spinal cord compression, and in patients with urinary tract obstruction.

After surgical castration, Decapeptyl SR 11.25 mg does not induce any further decrease in serum testosterone levels.

Long-term androgen deprivation either by bilateral orchidectomy or administration of GnRH agonists is associated with increased risk of bone loss and may lead to osteoporosis and increased risk of bone fracture.

Androgen deprivation therapy may prolong the QT interval.

In patients with a history of or risk factors for QT prolongation and in patients receiving concomitant medicinal products that might prolong the QT interval (see section 4.5) physicians should assess the benefit risk ratio including the potential for Torsade de pointes prior to initiating Decapeptyl SR 11.25 mg.

In addition, from epidemiological data, it has been observed that patients may experience metabolic changes (e.g. glucose intolerance, fatty liver), and an increased risk of cardiovascular disease during androgen deprivation therapy. However, prospective data did not confirm the link between treatment with GnRH agonists and an increase in cardiovascular mortality. Patients at high risk for metabolic or cardiovascular diseases should be carefully assessed before commencing treatment and their glucose, cholesterol and blood pressure adequately monitored during androgen deprivation therapy.

Metabolic changes may be more severe in these high risk patients. Patients at high risk of metabolic or cardiovascular disease and receiving androgen deprivation therapy should be monitored at appropriate intervals not exceeding 3 months.

Administration of triptorelin in therapeutic doses result in suppression of the pituitary gonadal system. Normal function is usually restored after treatment is discontinued. Diagnostic tests of pituitary gonadal function conducted during treatment and after discontinuation of therapy with GnRH agonists may therefore be misleading.

Due to androgen deprivation, treatment with GnRH analogues can increase the risk of anaemia. This risk should be assessed in treated patients and monitored appropriately.

In women

It should be confirmed that the patient is not pregnant before prescription of triptorelin.

The use of GnRH agonists is likely to cause reduction in bone mineral density averaging 1% per month during a six-month treatment period. Every 10% reduction in bone mineral density is linked with about a two to three times increased fracture risk.

No specific data are available for patients with established osteoporosis or with risk factors for osteoporosis (e.g. chronic alcohol abusers, smokers, long-term therapy with drugs that reduce bone mineral density, e.g. anticonvulsants or corticoids, family history of osteoporosis, malnutrition, e.g. anorexia nervosa). Since reduction in bone mineral density is likely to be more detrimental in these patients, treatment with triptorelin should be considered on an individual basis and only be initiated if the benefits of treatment outweigh the risk following a very careful appraisal. Consideration should be given to additional measures in order to counteract loss of bone mineral density.

Endometriosis

GnRH agonist is not recommended for patients under the age of 18 years. Careful attention should be given to adolescent and young women (specially less than 16 years of age) who may not have reached maximum bone density.

In patients treated with GnRH analogues for endometriosis, the addition of ABT (an estrogen and progestogen) has been shown to reduce mineral density loss and vasomotor symptoms (see 'Posology and Method of Administration' section 4.2 for further information).

Used at the recommended dose, Decapeptyl SR 11.25 mg causes constant hypogonadotropic amenorrhoea. If vaginal haemorrhage occurs after the first month, plasma oestradiol levels should be measured and if levels are below 50 pg/mL, possible organic lesions should be investigated.

After withdrawal of treatment, ovarian function resumes and ovulation occurs approximately 5 months after the last injection. A non-hormonal method of contraception should be used throughout treatment including for 3 months after the last injection.

Since menses should stop during Decapeptyl SR 11.25 mg treatment, the patient should be instructed to notify her physician if regular menstruation persists.

In paediatric population

Central precocious puberty

In girls, it should be confirmed that the patient is not pregnant before prescribing triptorelin.

Treatment of children with progressive brain tumours should follow a careful individual appraisal of the risks and benefits.

Pseudo-precocious puberty (gonadal or adrenal tumour or hyperplasia) and gonadotropin-independent precocious puberty (testicular toxicosis, familial Leydig cell hyperplasia) should be precluded.

In girls, initial ovarian stimulation at treatment initiation, followed by the treatment-induced oestrogen withdrawal, may lead, in the first month, to vaginal bleeding of mild or moderate intensity.

After discontinuation of treatment the development of puberty characteristics will occur.

Information with regards to future fertility is still limited. In most girls, regular menses will start on average one year after ending the therapy.

Bone mineral density may decrease during GnRH agonist therapy for central precocious puberty. However, after cessation of treatment subsequent bone mass accrual is preserved and peak bone mass in late adolescence does not seem to be affected by treatment.

Slipped capital femoral epiphysis can be seen after withdrawal of GnRH agonist treatment. The suggested theory is that the low concentrations of oestrogen during treatment with GnRH agonists weaken the epiphysial plate. The increase in growth velocity after stopping the treatment subsequently results in a reduction of the shearing force needed for displacement of the epiphysis.

Idiopathic intracranial hypertension

Idiopathic intracranial hypertension (pseudotumor cerebri) has been reported in paediatric patients receiving triptorelin. Patients should be warned for signs and symptoms of idiopathic intracranial hypertension, including severe or recurrent headache, vision disturbances and tinnitus. If idiopathic intracranial hypertension occurs, discontinuation of triptorelin should be considered.

4.5. Interaction with other medicinal products and other forms of interaction

Drugs which raise prolactin levels should not be prescribed concomitantly as they reduce the level of GnRH receptors in the pituitary.

When Decapeptyl SR 11.25 mg is co-administered with drugs affecting pituitary secretion of gonadotropins, caution should be exercised and it is recommended that the patient's hormonal status be supervised.

Since androgen deprivation treatment may prolong the QT interval, the concomitant use of Decapeptyl SR 11.25 mg with medicinal products known to prolong the QT interval or medicinal products able to induce Torsade de pointes such as class IA (e.g. quinidine, disopyramide) or class III (e.g. amiodarone, sotalol, dofetilide, ibutilide) antiarrhythmic medicinal products, methadone, moxifloxacin, antipsychotics, etc. should be carefully evaluated (see section 4.4).

4.6. Fertility, pregnancy and lactation

Pregnancy

Triptorelin should not be used during pregnancy since concurrent use of GnRH agonists is associated with a theoretical risk of abortion or foetal abnormality. Prior to treatment, potentially fertile women should be examined to exclude pregnancy. Non-hormonal methods of contraception should be employed during therapy until menses resume.

Animal studies have not revealed any teratogenic effects. During post-marketing surveillance and in a limited number of pregnant women who were exposed inadvertently to triptorelin, there were no reports of malformation or foetotoxicity attributable to the product. However, as the number of patients is too small to draw conclusions regarding the risk of foetal malformations or foetotoxicity, if a patient becomes pregnant while receiving triptorelin, therapy should be discontinued.

Lactation

Triptorelin is not recommended for use during lactation.

Fertility

There is no clinical evidence to suggest a causal connection between triptorelin and any subsequent abnormalities of oocyte development or pregnancy or outcome.

4.7. Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed. However, the ability to drive and use machines may be impaired should the patient experience dizziness, somnolence and visual disturbances (being possible undesirable effects of treatment), or resulting from the underlying disease.

4.8. Undesirable effects

Clinical trials experience

General tolerance in Men (see section 4.4)

Since patients suffering from locally advanced or metastatic, hormone-dependent prostate cancer are generally old and have other diseases frequently encountered in this aged population, more than 90% of the patients included in clinical trials reported adverse events, and often the causality is difficult to assess. As seen with other GnRH agonist therapies or after surgical castration, the most commonly observed adverse events related to triptorelin treatment were due to its expected pharmacological effects. These effects included hot flushes and decreased libido.

With the exception of immuno-allergic (rare) and injection site (< 5%) reactions, all adverse events are known to be related to testosterone changes.

The following adverse reactions considered as at least possibly related to triptorelin treatment were reported. Most of these events are known to be related to biochemical or surgical castration.

The frequency of the adverse reactions is classified as follows: very common (≥1/10); common (≥1/100 to < 1/10); uncommon (≥1/1000 to < 1/100); rare (≥1/10000 to < 1/1000); not known, (cannot be estimated from the available data).

** Reported following initial administration in patients with pituitary adenoma

*** During post market experience convulsions have been reported in patients receiving GnRH analogues, including triptorelin.

Triptorelin causes a transient increase in circulating testosterone levels within the first week after the initial injection of the sustained release formulation. With this initial increase in circulating testosterone levels, a small percentage of patients (≤ 5%) may experience a temporary worsening of signs and symptoms of their prostate cancer (tumour flare), usually manifested by an increase in urinary symptoms (< 2%) and metastatic pain (5%), which can be managed symptomatically. These symptoms are transient and usually disappear in one to two weeks.

Isolated cases of exacerbation of disease symptoms, either urethral obstruction or spinal cord compression by metastasis have occurred. Therefore, patients with metastatic vertebral lesions and/or with upper or lower urinary tract obstruction should be closely observed during the first few weeks of therapy (see section 4.4).

Patients receiving long-term treatment by GnRH analogue in combination with radiation therapy may have more side effects, mostly gastrointestinal and related to radiotherapy.

The use of GnRH agonists to treat prostate cancer may be associated with increased bone loss and may lead to osteoporosis and increases in the risk of bone fracture.

General tolerance in Women (see section 4.4)

As a consequence of decreased oestrogen levels, the most commonly reported adverse events (expected in 10% of women or more) were headache, libido decreased, sleep disorder, mood changes, dyspareunia, dysmenorrhoea, genital haemorrhage, ovarian hyperstimulation syndrome, ovarian hypertrophy pelvic pain, abdominal pain, vulvovaginal dryness, hyperhidrosis, hot flushes and asthenia.

The following adverse reactions, considered as at least possibly related to triptorelin treatment, were reported. Most of these are known to be related to biochemical or surgical castration.

Long term tolerance in children population:

• The long-term clinical trial 2-54-52014-159 (NCT00909844) included 35 patients, age ranging from 4 to 10.4 years, who had received treatment (up to 4 years) with triptorelin 11.25 mg. More than half of patients (20 patients: 57.1%) reported at least one adverse event during the study, of which the most frequent were abdominal pain (17.1%), injection site pain (11.4%), headache and hot flush (each 8.6%). Overall, the safety profile was similar as seen in the other CPP studies.

General

Increased lymphocytes count has been reported with patients undergoing GnRH agonist treatment. This secondary lymphocytosis is apparently related to GnRH induced castration and seems to indicate that gonadal hormones are involved in thymic involution.

Reporting of suspected adverse reactions
