  SFDA PIL (Patient Information Leaflet (PIL) are under review by Saudi Food and Drug Authority)

-        Dostinex contains the active ingredient cabergoline. This medicine belongs to a class of medicines called ‘dopamine agonists’. Dopamine is produced naturally in the body and helps to transmit messages to the brain.

-        Dostinex is used to stop breast milk production (lactation) soon after childbirth, stillbirth, abortion or miscarriage. It can also be used if you do not want to continue to breast-feed your baby once you have started.

-        Dostinex can also be used to treat other conditions caused by hormonal disturbance which can result in high levels of prolactin being produced. This includes lack of periods, infrequent and very light menstruation, periods in which ovulation does not occur and secretion of milk from your breast without breast-feeding. Also in conditions in which high levels of prolactin are due to unknown causes (idiopathic hyperprolactinaemia) or are caused by tumours of the pituitary gland in both men and women.

-        Cabergoline mimics the action of dopamine to reduce the production of prolactin in the blood. Prolactin is the hormone which stimulates the breast to produce milk.

-        Dostinex should only be used in adults. It is not suitable for children under the age of 16 years.

-        You must talk to a doctor or pharmacist if you do not feel better or if you feel worse.


Do not take Dostinex:

 

-        If you are allergic to cabergoline, to other medicines called ergot alkaloids, (e.g. pergolide, bromocriptine, lisuride, ergotamine or ergometrine) or to any of the other ingredients of this medicine (listed in section 6)

-        If you have severe liver disease

-        If you have high blood pressure in pregnancy associated with swelling and protein in the urine (toxaemia of pregnancy)

-        If you are being treated with anti-psychotics or have a history of mental illness associated with child-birth (puerperal psychosis)

-        If you are pregnant or breast-feeding

-        If you will be treated with Dostinex for a long period and have stiff and inflamed heart valves (cardiac valvulopathy)

-        If you have had fibrotic reactions (scar tissue) affecting your abdomen, heart or lungs.

 

Warnings and precautions

 

Talk to your doctor or pharmacist before taking Dostinex if you have or had any of the following conditions:

-        Disease that involves the heart and blood vessels (cardiovascular disease)

-        Cold hands and feet (Raynaud’s syndrome)

-        Gnawing pain in the abdomen when hungry (peptic ulcer) or bleeding from the stomach and intestines (gastrointestinal bleeding)

-        History of serious mental disease, particularly psychotic disorders

-        Reduced liver function

-        Kidney function abnormality or kidney disease

-        Increased blood pressure after giving birth

-        Fibrotic reactions (scar tissue) affecting your heart, lungs or abdomen. In case you are treated with Dostinex for a long period, your physician will check before starting treatment whether your heart, lungs and kidneys are in good condition. They will also have an echocardiogram (an ultrasound test of the heart) taken before treatment is started and at regular intervals during treatment. If fibrotic reactions occur treatment will have to be discontinued

-        Low blood pressure (postural hypotension) or you are taking any medicines to lower your blood pressure.

 

If you have just given birth you may be more at risk of certain conditions. These may include high blood pressure, heart attack, convulsion, stroke or mental health problems. Therefore, your doctor will need to check your blood pressure regularly during the treatment. Speak immediately to your doctor if you experience high blood pressure, chest pain or unusually severe or persistent headache (with or without vision problems).

 

Tell your doctor if you or your family/carer notices that you are developing urges or cravings to behave in ways that are unusual for you and you cannot resist the impulse, drive or temptation to carry out certain activities that could harm yourself or others. These are called impulse control disorders and can include behaviours such as addictive gambling, excessive eating or spending, an abnormally high sex drive or an increase in sexual thoughts or feelings. Your doctor may need to adjust or stop your dose.

 

It is recommended that women on long term treatment with Dostinex for hormonal disorders should have regular gynaecological exams including smear tests. Your doctor will continue to monitor your medical condition while you are taking Dostinex tablets.

 

Other medicines and Dostinex

 

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

 

Some medicines can reduce the effectiveness of Dostinex, these include:

-        Medicines used to treat mental illness (e.g. antipsychotic medicines like chlorpromazine, haloperidol)

-        Medicines for nausea and vomiting (e.g. domperidone, metoclopramide)

 

Some medicines can increase the amount of Dostinex in your blood and so could increase the side effects, these include:

-        Medicines for Parkinson’s disease

-        Medicines for severe migraine headaches (e.g. pergolide, bromocriptine, lisuride, ergotamine, dihydroergotamine, ergometrine or methysergide)

-        Antibiotics (e.g. erythromycin).

 

Dostinex with food and drink

 

See section 3 ‘How to take Dostinex’.

 

Pregnancy, breast-feeding and fertility

 

Pregnancy

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should also take care not to become pregnant for at least one month once you have stopped taking this medicine. If you become pregnant during treatment with Dostinex, stop taking Dostinex and inform your doctor who will then monitor your pregnancy as Dostinex can result in congenital abnormalities if you use it during pregnancy.

 

Breast-feeding

As Dostinex will stop you producing milk for your baby, you should not take this medicine if you plan to breast-feed. If you need to take Dostinex you should use another method of feeding your baby.

 

Driving and using machines

Dostinex can cause drowsiness (somnolence) and sudden sleepy episodes, in some cases without any warning signs or awareness. You are advised not to drive or operate machines or engage in activities requiring mental alertness or coordination during treatment with this medicine. Your doctor will decide if you can continue treatment on Dostinex if this occurs.

 

Dostinex contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.


Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

 

It is recommended you take Dostinex with or after food to help reduce feelings of nausea or vomiting.

·        To prevent milk production (lactation): You should take 1 mg (two 0.5 mg tablets) on the first day after delivery.

·        To stop lactation once you have started to breast-feed: You should take 0.25 mg (one half of Dostinex 0.5 mg tablet) every 12 hours for two days.

·        To reduce prolactin levels in other conditions: You should initially take one 0.5 mg tablet (to be taken in two doses) spread out over a week (e.g. half a tablet on Monday and the other half of the tablet on Thursday). Your dose will be increased up to a maximum dose of 4.5 mg per week or until you have responded fully to treatment. The maximum dose should not exceed 3 mg per day.

 

When you first start taking the tablet, it is recommended you slowly change position when trying to sit, stand or lie down, this is because this medicine may cause a drop in blood pressure that could make you dizzy when you move from a position. It is also recommended that you avoid alcohol and other medicines that cause drowsiness as this could increase the risk of dizziness.

 

During treatment your doctor may need to check your blood pressure, particularly in the first few days of treatment. A gynaecological assessment may also be carried out on the cells of your cervix or womb lining.

 

If you take more Dostinex than you should

If you take too many Dostinex tablets, contact your doctor immediately or go to the nearest hospital casualty department. Symptoms of overdose may include nausea, vomiting, gastric complaints, low blood pressure when standing, confusion/psychosis or hallucinations.

 

If you forget to take Dostinex

If you forget to take a dose take the next one as normal and tell your doctor if you have trouble remembering to take your tablets. Do not take a double dose to make up for a forgotten dose.

 

If you stop taking Dostinex

Your doctor will advise you how long to take Dostinex. You should not stop until your doctor tells you.

 

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

  نشرة الدواء تحت مراجعة الهيئة العامة للغذاء والدواء (اقرأ هذه النشرة بعناية قبل البدء في استخدام هذا المنتج لأنه يحتوي على معلومات مهمة لك)

-        يحتوي دوستينكس على المكون الفعال كابيرجولين. ينتمي هذا الدواء إلى مجموعة من الأدوية تسمى "ناهضات الدوبامين". يتم إنتاج الدوبامين في الجسم بصورة طبيعية ويساعد على نقل الرسائل إلى الدماغ.

-        يُستخدم دوستينكس لإيقاف إنتاج لبن الثدي (إفراز اللبن) بعد الولادة أو ولادة جنين ميت أو الإجهاض المتعمد أو الإجهاض العرضي، بفترة وجيزة. ويمكن استخدامه أيضًا إذا لم تعد لديك الرغبة في الاستمرار في إرضاع طفلك بعد أن بدأتِ.

-        يمكن استخدام دوستينكس أيضًا لعلاج حالات أخرى تسببها اضطراب هرموني يمكن أن يؤدي إلى إنتاج الجسم لمستويات مرتفعة من البرولاكتين. تشمل هذه الحالات انقطاع الدورة الشهرية، وعدم انتظامها أو قلة كميتها، والدورات الشهرية التي لا يحدث فيها التبويض، وإفراز اللبن من ثدييك بدون الرضاعة الطبيعية. يمكن استخدامه أيضًا في حالات ارتفاع مستويات البرولاكتين التي لا يعرف سببها (فرط برولاكتين الدم مجهول السبب) أو التي يكون سببها وجود أورام في الغدة النخامية في الرجال والسيدات.

-        يحاكي كابيرجولين عمل الدوبامين لتقليل إنتاج البرولاكتين في الدم. البرولاكتين هو الهرمون الذي يحفز الثدي لإنتاج اللبن.

-        ينبغي استخدام دوستينكس فقط في البالغين. وهو غير مناسب للأطفال تحت سن ١٦ عامًا.

-        يجب أن تتحدثي إلى أحد الأطباء أو إلى صيدلي إذا لم تشعري بتحسن أو إذا ساءت حالتك.

 موانع استعمال دوستينكس:

 

-        إذا كنت تعانين من حساسية تجاه كابيرجولين أو تجاه أدوية أخرى تدعى قلويدات الإرجوت (مثل بيرجوليد أو بروموكريبتين أو ليسوريد أو إرجوتامين أو إرجومترين) أو أي من المكونات الأخرى لهذا الدواء (مدرجة في القسم ٦)

-        إذا كنت تعانين من مرض شديد بالكبد

-        إذا كنت تعانين من ضغط الدم المرتفع أثناء الحمل المرتبط بالإصابة بتورم ووجود بروتين في البول (تسمم الدم أثناء الحمل)

-        إذا كنت تخضعين للعلاج بالأدوية المضادة للذهان أو لديك تاريخ من الإصابة بمرض عقلي مرتبط بالولادة (الذهان النفاسي)

-        إذا كنت حاملًا أو ترضعين طفلك رضاعة طبيعية

-        إذا كنت ستخضعين للعلاج بدوستينكس لفترة طويلة وتعانين من تصلب والتهاب صمامات القلب (اعتلال صمامات القلب)

-        إذا كنت قد عانيت من قبل من تفاعلات تليفية (تكون نسيج ندبي) أصابت بطنك أو قلبك أو رئتيك.

 

 

الاحتياطات عند استعمال دوستينكس

 

تحدثي إلى طبيبك أو الصيدلي قبل تناول دوستينكس إذا كنت تعانين أو عانيت من قبل من أي من الحالات التالية:

-        ألم مزعج في البطن عند الجوع (قرحة هضمية) أو النزيف من المعدة والأمعاء (النزيف المعدي المعوي)

-        تاريخ من الأمراض العقلية الخطيرة، خاصة الاضطرابات الذهانية

-        انخفاض في وظائف الكبد

-        وظائف غير طبيعية للكلى أو أمراض الكلى

-        ضغط الدم المرتفع بعد الولادة

-        تفاعلات تليفية (تكون نسيج ندبي) أصابت قلبك أو رئتيك أو بطنك. في حالة إذا ما كنت ستخضعين للعلاج بدوستينكس لفترة طويلة، فسيقوم طبيبك بالتحقق قبل بدء العلاج مما إذا كان قلبك ورئتاك وكليتاك في حالة جيدة. سيقوم أيضًا بإجراء مخطط صدى القلب (اختبار للقلب بالموجات فوق الصوتية) قبل البدء في العلاج ومن ثَم على فترات منتظمة أثناء العلاج. في حالة حدوث تفاعلات تليفية، فسوف يتم إيقاف العلاج

-        ضغط الدم المنخفض (انخفاض ضغط الدم الانتصابي) أو إذا كنت تتناولين أي أدوية لخفض ضغط دمك.

 

إذا كنتِ قد أنجبتِ للتو، فقد تكونين أكثر عرضة للإصابة ببعض الحالات. هذه الحالات قد تتضمن ضغط الدم المرتفع، أو الأزمة القلبية، أو التشنجات، أو السكتة الدماغية أو مشكلات تتعلق بالصحة العقلية. لذلك، سيتعين على طبيبكِ فحص ضغط دمكِ بانتظام أثناء العلاج. تحدثي إلى طبيبكِ على الفور إذا أصبتِ بضغط الدم المرتفع، أو ألم الصدر أو صداع شديد أو مستمر (مصحوب أو غير مصحوب بمشكلات في الرؤية).

 

أخبري طبيبك إذا لاحظت أو إذا لاحظت أسرتك/من يعتني بك أنه تنشأ لديك رغبات ملحة أو توق شديد للتصرف بطرق غير معتادة بالنسبة لك ولا يمكنك مقاومة الدافع أو الحافز أو الإغراء للقيام بممارسات معينة يمكنها أن تلحق الأذى بك أو بالآخرين. تدعى هذه باضطرابات السيطرة على الاندفاع ويمكن أن تشمل سلوكيات مثل إدمان القمار أو الإفراط في تناول الطعام أو إنفاق النقود أو زيادة الشهوة الجنسية بشكل غير طبيعي أو زيادة في الأفكار أو المشاعر الجنسية. قد يحتاج طبيبك إلى تعديل جرعتك أو إيقافها.

 

يوصى بأن تخضع السيدات اللاتي يتلقين علاجًا طويل الأمد بدوستينكس من أجل علاج الاضطرابات الهرمونية لفحوصات نسوية منتظمة تشمل اختبارات المسحة. سيستمر طبيبك في مراقبة حالتك الطبية أثناء تناولك لأقراص دوستينكس.

 

التداخلات الدوائية من أخذ هذا المستحضر مع أي أدوية أخرى أو أعشاب أو مكملات غذائية

تناول دوستينكس مع الطعام والشراب

انظري القسم ٣ "طريقة استخدام دوستينكس".

 

الحمل والرضاعة

الحمل

إذا كنتِ حاملًا أو تعتقدين أنك ربما تكونين حاملًا أو تخططين للحمل، فاستشيري طبيبك أو الصيدلي قبل تناول هذا الدواء. ينبغي عليك أيضًا توخي الحذر لئلا تصبحي حاملًا، لمدة شهر واحد على الأقل بمجرد توقفك عن تناول هذا الدواء. إذا أصبحت حاملًا أثناء العلاج بدوستينكس، فتوقفي عن تناول دوستينكس وأخبري طبيبك الذي سيقوم حينها بمراقبة حملك، حيث إن دوستينكس يمكن أن يؤدي إلى حدوث تشوهات خلقية إذا استخدمتيه أثناء الحمل.

 

الرضاعة الطبيعية

نظرًا لأن دوستينكس سوف يوقف إنتاج جسمك للبن اللازم لإرضاع طفلك، ينبغي عليك عدم تناول هذا الدواء إذا كنت تخططين لإرضاع طفلك رضاعة طبيعية. إذا كنت تحتاجين لتناول دوستينكس، ينبغي عليك استخدام وسيلة أخرى لإرضاع طفلك.

 

تأثير دوستينكس على القيادة واستخدام الآلات

 

يمكن أن يسبب دوستينكس النعاس (الشعور بالرغبة في النوم) ونوبات نعاس مفاجئة، في بعض الحالات بدون أي علامات تحذيرية أو وعي بحدوثها. ننصحك بعدم القيادة أو تشغيل الآلات أو ممارسة النشاطات التي تتطلب تيقظًا أو تناسقًا ذهنيًا أثناء العلاج بهذا الدواء. سوف يقرر طبيبك إذا ما كان يمكنك الاستمرار في العلاج بدوستينكس في حالة حدوث هذا.

 

معلومات هامة حول بعض مكونات دوستينكس

يحتوي دوستينكس على اللاكتوز

إذا أخبركِ طبيبكِ بأنك مصابة بعدم تحمل بعض السكريات، فتواصلي مع طبيبكِ قبل تناول هذا المنتج الدوائي.

https://localhost:44358/Dashboard

احرصي دومًا على تناول هذا الدواء تمامًا كما أخبرك طبيبك أو الصيدلي. استشيري طبيبك أو الصيدلي إذا لم تكوني متأكدة مما يجب عليك فعله.

 

ينصح بأن تتناولي دوستينكس مع الطعام أو بعده للمساعدة على تقليل الشعور بالغثيان أو القيء.

·        لمنع إنتاج اللبن (إفراز اللبن): ينبغي عليك تناول ١ ملجم (قرصين ٠.٥ ملجم) في أول يوم بعد الولادة.

·        لإيقاف إفراز اللبن بعد أن بدأت في الرضاعة الطبيعية: ينبغي عليك تناول ٠.٢٥ ملجم (نصف قرص دوستينكس ٠.٥ ملجم) كل ١٢ ساعة لمدة يومين.

·        لخفض مستويات البرولاكتين في حالات أخرى: ينبغي عليك في البداية تناول قرص واحد ٠.٥ ملجم (يتم تناوله على جرعتين) مقسمًا على مدار أسبوع (مثال: نصف قرص في يوم الإثنين والنصف الآخر من القرص في يوم الخميس). ستتم زيادة جرعتك وصولًا إلى حد أقصى للجرعة يبلغ ٤.٥ ملجم في الأسبوع أو إلى أن تستجيبي استجابة كاملة للعلاج. ينبغى ألا يتجاوز الحد الأقصى للجرعة ٣ ملجم في اليوم.

 

عندما تبدئين في تناول القرص لأول مرة، يوصى بتغيير وضعك ببطء عند محاولة الجلوس أو الوقوف أو الاستلقاء، حيث إن هذا الدواء قد يسبب انخفاضًا في ضغط الدم مما يمكن أن يشعرك بالدوار عند الانتقال من وضع لآخر. يوصى كذلك بتجنب تناول الكحول والأدوية الأخرى التي تسبب النعاس حيث يمكن أن يزيد هذا من خطر الإصابة بالدوار.

 

من الممكن أن يحتاج طبيبك إلى فحص ضغط دمك أثناء العلاج، خاصة في الأيام القليلة الأولى من العلاج. من الممكن كذلك أن يتم إجراء تقييم نسوي تخصصي لخلايا بطانة الرحم أو عنق الرحم الخاصة بك.

 

الجرعة الزائدة من دوستينكس

إذا تناولت كمية من أقراص دوستينكس أكبر مما ينبغي، فاتصلي بطبيبك على الفور أو اذهبي إلى قسم الإصابات بأقرب مستشفى. يمكن أن تتضمن أعراض تناول جرعة مفرطة الغثيان أو القيء أو الشكاوى المتعلقة بالمعدة أو ضغط الدم المنخفض عند الوقوف أو التشوش/الذهان أو الهلاوس.

 

نسيان تناول جرعة دوستينكس

إذا نسيت تناول إحدى الجرعات، فتناولي الجرعة التالية كالمعتاد وأخبري طبيبك إذا واجهت صعوبة في تذكر تناول أقراصك. لا تأخذي جرعة مضاعفة لتعويض جرعة منسية.

 

التوقف عن تناول دوستينكس

سوف يخبرك طبيبك بالمدة التي ينبغي خلالها أن تتناولي دوستينكس. ينبغي عليك عدم التوقف عن تناول دوستينكس حتى يخبرك طبيبك بذلك.

 

إذا كان لديك مزيد من الأسئلة بشأن استخدام هذا الدواء، فاسألي طبيبك أو الصيدلي.

Dostinex 0.5 mg Tablets

One Dostinex tablet contains 0.5 mg cabergoline. Excipients with known effect: Each tablet contains 75.90 mg of lactose anhydrous. For the full list of excipients, see section 6.1.

Tablet. White, flat, oblong, with engraving “PU” divided by a score on one side; engraving “700” and light score above and below the central “0” on other side.

Inhibition/suppression of physiological lactation

Cabergoline is indicated for the inhibition of physiological lactation soon after delivery and for suppression of already established lactation:

1.    After parturition, when the mother elects not to breast feed the infant or when breast feeding is contraindicated due to medical reasons related to the mother or the new-born.

2.    After stillbirth or abortion.

 

Cabergoline prevents/suppresses physiological lactation by inhibiting prolactin secretion.

 

In controlled clinical trials, cabergoline given as a single 1 mg administration during the first day post-partum, was effective in inhibiting milk secretion, as well as breast engorgement and pain in 70 - 90% of the women.  Less than 5% of women experienced rebound breast symptomatology during the third post-partum week (which was usually mild in severity).

 

Suppression of milk secretion and relief of breast engorgement and pain are obtained in approximately 85% of nursing women treated with a total dose of 1 mg cabergoline given in four divided doses over two days.  Rebound breast symptomatology after day 10 is uncommon (approximately 2% of cases).

 

Treatment of hyperprolactinaemic disorders

Cabergoline is indicated for the treatment of dysfunctions associated with hyperprolactinaemia, including amenorrhoea, oligomenorrhoea, anovulation and galactorrhoea.  Cabergoline is indicated in patients with prolactin-secreting pituitary adenomas (micro- and macroprolactinomas), idiopathic hyperprolactinaemia, or empty sella syndrome with associated hyperprolactinaemia, which represent the basic underlying pathologies contributing to the above clinical manifestations.

 

On chronic therapy, cabergoline at doses ranging between 1 and 2 mg per week, was effective in normalising serum prolactin levels in approximately 84% of hyperprolactinaemic patients.  Regular cycles were resumed in 83% of previously amennorhoeic women.  Restoration of ovulation was documented in 89% of women with progesterone levels monitored during the luteal phase.  Galactorrhoea disappeared in 90% of cases showing this symptom before therapy.  Reduction in tumour size was obtained in 50 - 90% of female and male patients with micro- or macroprolactinoma.


Cabergoline is to be administered by the oral route.  Since in clinical studies cabergoline has been mainly administered with food and since the tolerability of this class of compounds is improved with food, it is recommended that cabergoline be preferably taken with meals for all the therapeutic indications.

 

Inhibition/suppression of physiological lactation

For inhibition of lactation cabergoline should be administered during the first day post-partum.  The recommended therapeutic dose is 1 mg (two 0.5 mg tablets) given as a single dose.

For suppression of established lactation the recommended therapeutic dosage regimen is 0.25 mg (one-half 0.5 mg tablet) every 12 hours for two days (1 mg total dose).  This dosage regimen has been demonstrated to be better tolerated than the single dose regimen in women electing to suppress lactation having a lower incidence of adverse events, in particular of hypotensive symptoms.

 

Treatment of hyperprolactinaemic disorders

The recommended initial dosage of cabergoline is 0.5 mg per week given in one or two (one-half of one 0.5 mg tablet) doses (e.g. on Monday and Thursday) per week.  The weekly dose should be increased gradually, preferably by adding 0.5 mg per week at monthly intervals until an optimal therapeutic response is achieved.  The therapeutic dosage is usually 1 mg per week and ranges from 0.25 mg to 2 mg per week.  Doses of cabergoline up to 4.5 mg per week have been used in hyperprolactinaemic patients.

 

The maximum dose should not exceed 3mg per day.

 

The weekly dose may be given as a single administration or divided into two or more doses per week according to patient tolerability.  Division of the weekly dose into multiple administrations is advised when doses higher than 1 mg per week are to be given since the tolerability of doses greater than 1 mg taken as a single weekly dose has been evaluated only in a few patients.

 

Patients should be evaluated during dose escalation to determine the lowest dosage that produces the therapeutic response.  Monitoring of serum prolactin levels at monthly intervals is advised since, once the effective therapeutic dosage regimen has been reached, serum prolactin normalisation is usually observed within two to four weeks.

 

After cabergoline withdrawal, recurrence of hyperprolactinaemia is usually observed.  However, persistent suppression of prolactin levels has been observed for several months in some patients.  Of the group of women followed up, 23/29 had ovulatory cycles which continued for greater than 6 months after cabergoline discontinuation.

 

Paediatric population

The safety and efficacy of cabergoline has not been established in subjects less than 16 years of age.

 

Use in the elderly

As a consequence of the indications for which cabergoline is presently proposed, the experience in elderly is very limited.  Available data do not indicate a special risk.


Hypersensitivity to cabergoline, any of the excipients listed in section 6.1 or any ergot alkaloid. History of pulmonary, pericardial and retroperitoneal fibrotic disorders. Cabergoline is contraindicated in patients with hepatic insufficiency and with toxaemia of pregnancy. Cabergoline should not be co-administered with anti-psychotic medications or administered to women with a history of puerperal psychosis. For long-term treatment: Evidence of cardiac valvulopathy as determined by pre-treatment echocardiography. (See section 4.4).

General:

The safety and efficacy of cabergoline have not yet been established in patients with renal and hepatic disease.  As with other ergot derivatives, cabergoline should be given with caution to patients with severe cardiovascular disease, Raynaud's syndrome, renal insufficiency, peptic ulcer or gastrointestinal bleeding, or with a history of serious, particularly psychotic, mental disorders.  Particular care should be taken when patients are taking concomitant psychoactive medication.

 

Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

 

Symptomatic hypotension can occur with cabergoline administration for any indication.  Care should be exercised when administering cabergoline concomitantly with other drugs known to lower blood pressure.

 

The effects of alcohol on overall tolerability of cabergoline are currently unknown.

 

Before cabergoline administration, pregnancy should be excluded and after treatment pregnancy should be prevented for at least one month.

 

Hepatic Insufficiency:

Lower doses should be considered in patients with severe hepatic insufficiency who receive prolonged treatment with cabergoline. Compared to normal volunteers and those with lesser degrees of hepatic insufficiency, an increase in AUC has been seen in patients with severe hepatic insufficiency (Child-Pugh Class C) who received a single 1 mg dose.

 

Postural Hypotension:

Postural hypotension can occur following administration of cabergoline.  Care should be exercised when administering cabergoline concomitantly with other drugs known to lower blood pressure.

 

Somnolence/Sudden Sleep Onset:

Cabergoline has been associated with somnolence. Dopamine agonists can be associated with sudden sleep onset episodes in patients with Parkinson’s disease.  Sudden onset of sleep during daily activities, in some cases without awareness or warning signs, has been reported uncommonly.  Patients must be informed of this and advised to exercise caution while driving or operating machines during treatment with cabergoline.  Patients who have experienced somnolence and/or an episode of sudden sleep onset must refrain from driving or operating machines. Furthermore a reduction in dosage or termination of therapy may be considered. (See section 4.7)

 

Impulse control disorders:

Patients should be regularly monitored for the development of impulse control disorders. Patients and carers should be made aware that behavioural symptoms of impulse control disorders including pathological gambling, increased libido, hypersexuality, compulsive spending or buying, binge eating and compulsive eating can occur in patients treated with dopamine agonists including Dostinex. Dose reduction/tapered discontinuation should be considered if such symptoms develop.

 

Inhibition/suppression of physiological lactation:

As with other ergot derivatives, cabergoline should not be used in women with pregnancy-induced hypertension, for example, preeclampsia or post-partum hypertension, unless the potential benefit is judged to outweigh the possible risk.

 

Serious adverse events including hypertension, myocardial infarction, seizures, stroke or psychiatric disorders have been reported in postpartum women treated with cabergoline for inhibition of lactation.  In some patients the development of seizures or stroke was preceded by severe headache and/or transient visual disturbances. Blood pressure should be carefully monitored after the treatment. If hypertension, suggestive chest pain, severe, progressive, or unremitting headache (with or without visual disturbances), or evidence of central nervous system toxicity develop, cabergoline should be discontinued and the patient should be evaluated promptly.

 

In post-partum studies with cabergoline, blood pressure decreases were mostly asymptomatic and were frequently observed on a single occasion 2 to 4 days after treatment.  Since decreases in blood pressure are frequently noted during the puerperium, independently of drug therapy, it is likely that many of the observed decreases in blood pressure after cabergoline administration were not drug-induced.  However, periodic monitoring of blood pressure, particularly during the first few days after cabergoline administration, is advised.

 

A single dose of 0.25 mg of cabergoline should not be exceeded in nursing women treated for suppression of established lactation to avoid potential postural hypotension (see section 4.2). A clinical study exploring the efficacy and tolerability of 0.5 mg of cabergoline given as a single dose for suppression of lactation has shown that the risk of side effects is approximately doubled in this indication if the drug is administered as a single dose of 0.5 mg.

 

Treatment of hyperprolactinaemic disorders:

Because hyperprolactinaemia accompanied with amenorrhoea/galactorrhoea and infertility may be associated with pituitary tumour, a complete evaluation of the pituitary is indicated before treatment with cabergoline is initiated.

 

Cabergoline restores ovulation and fertility in women with hyperprolactinaemic hypogonadism.

 

Because pregnancy might occur prior to reinitiation of menses, a pregnancy test is recommended at least every four weeks during the amenorrhoeic period and, once menses are reinitiated, every time a menstrual period is delayed by more than three days.  Women who wish to avoid pregnancy should be advised to use mechanical contraception during treatment with cabergoline and after discontinuation of cabergoline until recurrence of anovulation. As a precautionary measure, women who become pregnant should be monitored to detect signs of pituitary enlargement since expansion of pre-existing pituitary tumours may occur during gestation.

 

Before administration of cabergoline, pregnancy should be excluded. Because clinical experience is still limited and the product has a long half-life, as a precautionary measure it is recommended that once regular ovulatory cycles have been achieved women seeking pregnancy discontinue cabergoline one month before intended conception. Should pregnancy occur during treatment, cabergoline is to be discontinued.  As a precautionary measure, women who become pregnant should be monitored to detect signs of pituitary enlargement since expansion of pre-existing pituitary tumours may occur during gestation.

 

Regular gynaecological assessment, including cervical and endometrial cytology, is recommended for patients taking cabergoline for extensive periods.

 

Fibrosis and cardiac valvulopathy and possibly related clinical phenomena:

Fibrotic and serosal inflammatory disorders such as pleuritis, pleural effusion, pleural fibrosis, pulmonary fibrosis, pericarditis, pericardial effusion, cardiac valvulopathy involving one or more valves (aortic, mitral and tricuspid) or retroperitoneal fibrosis have occurred after prolonged usage of ergot derivatives with agonist activity at the serotonin 5HT2B receptor, such as cabergoline. In some cases, symptoms or manifestations of cardiac valvulopathy improved after discontinuation of cabergoline.

 

Erythrocyte sedimentation rate (ESR) has been found to be abnormally increased in association with pleural effusion/fibrosis. Chest x-ray examination is recommended in cases of unexplained ESR increases to abnormal values.

 

Valvulopathy has been associated with cumulative doses, therefore, patients should be treated with the lowest effective dose. At each visit, the risk benefit profile of cabergoline treatment for the patient should be reassessed to determine the suitability of continued treatment with cabergoline.

 

Before initiating long-term treatment:

All patients must undergo a cardiovascular evaluation, including echocardiogram to assess the potential presence of asymptomatic valvular disease. It is also appropriate to perform baseline investigations of erythrocyte sedimentation rate or other inflammatory markers, lung function/chest X-ray and renal function prior to initiation of therapy. In patients with valvular regurgitation, it is not known whether cabergoline treatment might worsen the underlying disease. If fibrotic valvular disease is detected, the patient should not be treated with cabergoline (see section 4.3).

 

During long-term treatment:

Fibrotic disorders can have an insidious onset and patients should be regularly monitored for possible manifestations of progressive fibrosis. Therefore, during treatment, attention should be paid to the signs and symptoms of:

·        Pleuro-pulmonary disease such as dyspnoea, shortness of breath, persistent cough or chest pain.

·        Renal insufficiency or ureteral/abdominal vascular obstruction that may occur with pain in the loin/flank and lower limb oedema as well as any possible abdominal masses or tenderness that may indicate retroperitoneal fibrosis.

·        Cardiac failure: cases of valvular and pericardial fibrosis have often manifested as cardiac failure. Therefore, valvular fibrosis (and constrictive pericarditis) should be excluded if such symptoms occur.

 

Clinical diagnostic monitoring for development of fibrotic disorders, as appropriate, is essential. Following treatment initiation, the first echocardiogram must occur within 3-6 months, thereafter, the frequency of echocardiographic monitoring should be determined by appropriate individual clinical assessment with particular emphasis on the above-mentioned signs and symptoms, but must occur at least every 6 to 12 months.

 

Cabergoline should be discontinued if an echocardiogram reveals new or worsened valvular regurgitation, valvular restriction or valve leaflet thickening (see section 4.3).

 

The need for other clinical monitoring (e.g. physical examination including, cardiac auscultation, X-ray, CT scan) should be determined on an individual basis.

 

Additional appropriate investigations such as erythrocyte sedimentation rate, and serum creatinine measurements should be performed if necessary to support a diagnosis of a fibrotic disorder.


The concomitant use of other drugs during early puerperium, particularly of ergot alkaloids, was not associated with detectable interactions modifying the efficacy and safety of cabergoline.

 

No information is available about the interaction between cabergoline and other ergot alkaloids; therefore, the concomitant use of these medications during long-term treatment with cabergoline is not recommended.

 

Since cabergoline exerts its therapeutic effect by direct stimulation of dopamine receptors, it should not be concurrently administered with drugs which have dopamine-antagonist activity (such as phenothiazines, butyrophenones, thioxanthenes, metoclopramide) since these might reduce the prolactin-lowering effect of cabergoline.

 

As with other ergot derivatives, cabergoline should not be used with macrolide antibiotics (e.g. erythromycin) due to increased systemic bioavailability of cabergoline.


There are no adequate and well-controlled studies from the use of cabergoline in pregnant women. Animal studies have not demonstrated teratogenic effects, but reduced fertility and embryo-toxicity were observed in association with pharmacodynamic activity (see section 5.3).

 

In a twelve year observational study on pregnancy outcomes following cabergoline therapy, information is available on 256 pregnancies.  Seventeen of these 256 pregnancies (6.6%) eventuated in major congenital malformations or abortion.  Information is available on 23/258 infants who had a total of 27 neonatal abnormalities, both major and minor.  Musculoskeletal malformations were the most common neonatal abnormality (10), followed by cardio-pulmonary abnormalities (5).  There is no information on perinatal disorders or long-term development of infants exposed to intra-uterine cabergoline.  Based on recent published literature, the prevalence of major congenital malformations in the general population has been reported to be 6.9% or greater.  Rates of congenital abnormality vary between different populations. It is not possible to accurately determine if there is an increased risk as no control group was included.

 

Cabergoline should only be used during pregnancy if clearly indicated and after an accurate benefit/risk evaluation. (See section 4.4).

Due to the long half-life of the drug and limited data on in utero exposure, women planning to become pregnant should discontinue cabergoline one month before intended conception. If conception occurs during therapy, treatment should be discontinued as soon as pregnancy is confirmed to limit foetal exposure to the drug.

In rats, cabergoline and/or its metabolites are excreted in milk.  No information is available on the excretion in breast milk in humans; however, mothers should be advised not to breast-feed in case of failed lactation inhibition/suppression by cabergoline.  Since it prevents lactation, cabergoline should not be administered to mothers with hyperprolactinemic disorders who wish to breast-feed their infants.


Patients should be careful when performing actions which require fast and accurate reaction during treatment initiation.

During the first days of cabergoline administration, patients should be cautioned about re-engaging in activities requiring rapid and precise responses such as driving an automobile or operating machinery.

 

Patients being treated with cabergoline and presenting with somnolence must be informed to refrain from driving or engaging in activities where impaired alertness may put themselves and others at risk of serious injury or death (e.g. operating machines) until such episodes and somnolence have resolved. (See section 4.4).

 


Adverse events are generally dose-related.  In patients known to be intolerant to dopaminergic drugs, the likelihood of adverse events may be lessened by starting therapy with cabergoline at reduced doses, e.g. 0.25 mg once a week, with subsequent gradual increase until the therapeutic dosage is reached.  If persistent or severe adverse events occur, temporary reduction of dosage followed by a more gradual increase, e.g. increments of 0.25 mg/week every two weeks, may increase tolerability.

The following undesirable effects have been observed and reported during treatment with cabergoline with the following frequencies: Very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to ≤1/100); rare (≥1/10,000 to ≤1/1,000); very rare (≤1/10,000), not known (cannot be estimated from the available data).

Symptoms of overdose would likely be those of over-stimulation of dopamine receptors e.g. nausea, vomiting, gastric complaints, postural hypotension, confusion/psychosis or hallucinations.

 

Supportive measures should be taken to remove any unabsorbed drug and maintain blood pressure, if necessary.  In addition, the administration of dopamine antagonist drugs may be advisable.


Pharmacotherapeutic group: Prolactine inhibitors, ATC code: G02CB03

 

Cabergoline is a dopaminergic ergoline derivative endowed with a potent and long-lasting PRL-lowering activity.  It acts by direct stimulation of the D2-dopamine receptors on pituitary lactotrophs, thus inhibiting PRL secretion.  In rats the compound decreases PRL secretion at oral doses of 3-25 mcg/kg, and in-vitro at a concentration of 45 pg/ml.  In addition, cabergoline exerts a central dopaminergic effect via D2 receptor stimulation at oral doses higher than those effective in lowering serum PRL levels.  The long lasting PRL-lowering effect of cabergoline is probably due to its long persistence in the target organ as suggested by the slow elimination of total radioactivity from the pituitary after single oral dose in rats (t½ of approximately 60 hours).

 

The pharmacodynamic effects of cabergoline have been studied in healthy volunteers, puerperal women and hyperprolactinaemic patients.  After a single oral administration of cabergoline (0.3 - 1.5 mg), a significant decrease in serum PRL levels was observed in each of the populations studied.  The effect is prompt (within 3 hours from administration) and persistent (up to 7 - 28 days in healthy volunteers and hyperprolactinaemic patients, and up to 14 - 21 days in puerperal women).  The PRL-lowering effect is dose-related both in terms of degree of effect and duration of action.

With regard to the endocrine effects of cabergoline not related to the antiprolactinaemic effect, available data from humans confirm the experimental findings in animals indicating that the test compound is endowed with a very selective action with no effect on basal secretion of other pituitary hormones or cortisol.  The pharmacodynamic actions of cabergoline not correlated with the therapeutic effect only relate to blood pressure decrease.  The maximal hypotensive effect of cabergoline as single dose usually occurs during the first 6 hours after drug intake and is dose-dependent both in terms of maximal decrease and frequency.


The pharmacokinetic and metabolic profiles of cabergoline have been studied in healthy volunteers of both sexes and in female hyperprolactinaemic patients.

 

After oral administration of the labelled compound, radioactivity was rapidly absorbed from the gastrointestinal tract as the peak of radioactivity in plasma was between 0.5 and 4 hours.

 

Ten days after administration about 18% and 72% of the radioactive dose was recovered in urine and faeces, respectively.  Unchanged drug in urine accounted for 2-3% of the dose.

 

In urine, the main metabolite identified was 6-allyl-8b-carboxy-ergoline, which accounted for 4-6% of the dose.  Three additional metabolites were identified in urine, which accounted overall for less than 3% of the dose.  The metabolites have been found to be much less potent than cabergoline in inhibiting prolactin secretion in vitro.  Cabergoline biotransformation was also studied in plasma of healthy male volunteers treated with [14C]-cabergoline: a rapid and extensive biotransformation of cabergoline was shown.

 

The low urinary excretion of unchanged cabergoline has been confirmed also in studies with non-radioactive product.  The elimination half-life of cabergoline, estimated from urinary excretion rates, is long (63-68 hours in healthy volunteers (using a radio-immuno assay), 79-115 hours in hyperprolactinaemic patients (using a HPLC method). 

 

On the basis of the elimination half-life, steady state conditions should be achieved after 4 weeks, as confirmed by the mean peak plasma levels of cabergoline obtained after a single dose (37 ± 8 pg/ml) and after a 4 week multiple regimen (101 ± 43 pg/ml).

In vitro experiments showed that the drug at concentrations of 0.1-10 ng/ml is 41-42% bound to plasma proteins.  Food does not appear to affect absorption and disposition of cabergoline.


There were maternotoxic effects but no teratogenic effects in mice given cabergoline at doses up to 8 mg/kg/day (approximately 55 times the maximum recommended human dose) during the period of organogenesis.

A dose of 0.012 mg/kg/day (approximately 1/7 the maximum recommended human dose) during the period of organogenesis in rats caused an increase in post-implantation embryofoetal losses. These losses could be due to the prolactin inhibitory properties of cabergoline in rats. At daily doses of 0.5 mg/kg/day (approximately 19 times the maximum recommended human dose) during the period of organogenesis in the rabbit, cabergoline caused maternotoxicity characterized by a loss of body weight and decreased food consumption. Doses of 4 mg/kg/day (approximately 150 times the maximum recommended human dose) during the period of organogenesis in the rabbit caused an increased occurrence of various malformations. However, in another study in rabbits, no treatment-related malformations or embryofoetotoxicity were observed at doses up to 8 mg/kg/day (approximately 300 times the maximum recommended human dose).
