Patient leaflet - Stacar 50 mg/12.5 mg/200 mg film-coated tablets

1. What Stacar is and what it is used for

Stacar contains three active substances (levodopa, carbidopa and entacapone) in one film-coated tablet. Stacar is used for the treatment of Parkinson's disease.

Parkinson's disease is caused by low levels of a substance called dopamine in the brain. Levodopa increases the amount of dopamine and hence reduces the symptoms of Parkinson's disease. Carbidopa

and entacapone improve the antiparkinson effects of levodopa.

2. W hat you need to know before you take Stacar

Do not take Stacar if you:

Ÿ are allergic to levodopa, carbidopa or entacapone, or any of the other ingredients of this medicine (listed in section 6)

Ÿ have narrow-angle glaucoma (an eye disorder)

Ÿ have a tumour of the adrenal gland

Ÿ are taking certain medicines for treating depression (combinations

of selective MAO-A and MAO-B inhibitors, or non-selective MAO-inhibitors)

Ÿ have ever had neuroleptic malignant syndrome (NMS – this is a

rare reaction to medicines used to treat severe mental disorders)

Ÿ have ever had non-traumatic rhabdomyolysis (a rare muscle

disorder)

Ÿ have a severe liver disease.

Warnings and precautions

Ÿ a liver problem, because your dose may need to be adjusted Talk to your doctor or pharmacist before taking Stacar if you have or have ever had:

Ÿ a heart attack or any other diseases of the heart including cardiac

arrhythmias, or of the blood vessels

Ÿ kidney or hormone-related diseases

Ÿ stomach ulcers or convulsions

Ÿ if you experience prolonged diarrhoea consult your doctor as it

may be a sign of inflammation of the colon

Ÿ any form of severe mental disorder like psychosis

Ÿ chronic wide-angle glaucoma, because your dose may need to be

adjusted and the pressure in your eyes may need to be monitored.

Consult your doctor if you are currently taking:

Ÿ antipsychotics (medicines used to treat psychosis)

Ÿ a medicine which may cause low blood pressure when rising from

a chair or bed. Be aware that Stacar may make these reactions worse.

Consult your doctor if during the treatment with Stacar you:

Ÿ notice that your muscles get very rigid or jerk violently, or if you

get tremors, agitation, confusion, fever, rapid pulse, or wide fluctuations in your blood pressure. If any of this happens, contact your doctor immediately

Ÿ feel depressed, have suicidal thoughts, or notice unusual changes

in your behaviour

Ÿ find yourself suddenly falling asleep, or if you feel very drowsy. If

this happens, do not drive or use any tools or machines (see also section 'Driving and using machines')

started to take Stacar. If this happens, your doctor may need to change the dose of your antiparkinson medicine

Ÿ experience diarrhoea: monitoring of your weight is recommended

Ÿ experience progressive anorexia, asthenia (weakness, exhaustion)

and weight decrease within a relatively short period of time. If this happens, a general medical evaluation including liver function should be considered

Ÿ feel the need to stop using Stacar, see section 'If you stop taking

Stacar.

Talk to your doctor or pharmacist if you think the effect of Stacar is too strong or too weak, or if you experience possible side effects. Tell your doctor if you or your family/carer notices you are developing:

Ÿ addiction-like symptoms leading to craving for large doses of

Stacar and other medicines used to treat Parkinson's disease

Ÿ alpha-methyldopa, used to treat high blood pressure Ÿ urges or cravings to behave in ways that are unusual for you or you cannot resist the impulse, drive or temptation to carry out certain activities that could harm yourself or others. These behaviours are called impulse control disorders and can include addictive gambling, excessive eating or spending, an abnormally high sex drive or a preoccupation with an increase in sexual thoughts or feelings. Your doctor may need to review your treatments.

Your doctor may take some regular laboratory tests during a long term treatment with Stacar.

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. If you must undergo surgery, please tell your doctor that you are using Stacar.

Stacar is not recommended to be used for treatment of extrapyramidal symptoms (e.g. involuntary movements, shaking, muscle rigidity and muscle contractions) caused by other medicines.

Children and adolescents

Experience with Stacar in patients under 18 years is limited. Therefore, the use of Stacar in children or adolescents is not recommended.

Other medicines and Stacar

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Do not take Stacar if you are taking certain medicines for treating depression (combinations of selective MAO-A and MAO-B inhibitors, or non-selective MAO inhibitors).

Stacar may increase the effects and side effects of certain medicines. These include:

Ÿ medicines used to treat depression such as moclobemide, amitriptyline, desipramine, maprotiline, venlafaxine and paroxetine

Ÿ rimiterole and isoprenaline, used to treat respiratory diseases

Ÿ adrenaline, used for severe allergic reactions

Ÿ noradrenaline, dopamine and dobutamine, used to treat heart diseases and low blood pressure

Ÿ apomorphine, which is used to treat Parkinson's disease.

The effects of Stacar may be weakened by certain medicines. These include:

Ÿ dopamine antagonists used to treat mental disorders, nausea and vomiting

Ÿ phenytoin, used to prevent convulsions

Ÿ papaverine used to relax the muscles.

Stacar may make it harder for you to digest iron.

Therefore, do not take Stacar and iron supplements

at the same time. After taking one of them, wait at

least 2 to 3 hours before taking the other.

Stacar with food and drink

Stacar may be taken with or without food. For some patients, Stacar may not be well absorbed if it is taken with, or shortly after eating protein-rich food (such as meats, fish, dairy products, seeds and nuts). Consult your doctor if you think this applies to you.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Do not breast-feed during treatment with Stacar.

Driving and using machines

Stacar may lower your blood pressure, which may make you feel light-headed or dizzy. Therefore, be particularly careful when you drive or when you use any tools or machines.

If you feel very drowsy, or if you sometimes find yourself suddenly falling asleep, wait until you feel fully awake again before driving or doing anything else that requires you to be alert. Otherwise, you may put yourself and others at risk of serious injury or death.

3. How to take Stacar

For adults and elderly

Ÿ Your doctor will tell you exactly how many tablets of Stacar to take each day.

Ÿ The tablets are not intended to be split or broken into smaller pieces.

Ÿ Take only one tablet each time.

Ÿ Depending on how you respond to treatment, your doctor may suggest a higher or lower dose.

Ÿ If you are taking Stacar 50 mg/12.5 mg/200 mg, 75 mg/18.75 mg/200 mg, 100 mg/25 mg/200 mg, 125 mg/31.25 mg/200 mg or 150 mg/37.5 mg/200 mg tablets, do not take more than 10 tablets per day.

Ÿ If you are taking Stacar 175 mg/43.75 mg/200 mg tablets, do not take more than 8 tablets of this strength per day.

Ÿ If you are taking Stacar 200 mg/50 mg/200 mg, do not take more than 7 tablets of this strength per day.

If you take more Stacar than you should

If you have accidentally taken more Stacar tablets than you should, talk to your doctor or pharmacist immediately. In case of an overdose you may feel confused or agitated, your heart rate may be slower or faster than normal or the colour of your skin, tongue, eyes or urine may change.

If you forget to take Stacar

Do not stop taking Stacar unless your doctor tells you to. In such a case your doctor may need to adjust your other antiparkinson medicines, especially levodopa, to give sufficient control of your symptoms. If you suddenly stop taking Stacar and other antiparkinsonian medicines it may result in unwanted side effects. Do not take a double dose to make up for a forgotten tablet.

Ÿ If it is more than 1 hour until your next dose: Take one tablet as

soon as you remember, and the next tablet at the normal time.

Ÿ If it is less than 1 hour until your next dose: Take a tablet as soon

as you remember, wait 1 hour, then take another tablet. After that carry on as normal.

Always leave at least an hour between Stacar tablets, to avoid possible side effects.

If you stop taking Stacar

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