What SIMPRAL is used for
SIMPRALis used to treat the symptoms of Parkinson's disease
Parkinson's disease is a disease of the brain that affects body movement.
The symptoms of Parkinson's disease are caused by a lack of dopamine, a naturally occurring chemical produced by certain brain cells.
Dopamine relays messages in the part of the brain that controls movement. When too little dopamine is produced, this results in Parkinson's disease.
SIMPRAL works by having a similar effect as dopamine in the brain.
How SIMPRAL works
SIMPRAL contains the active ingredient pramipexole dihydrochloride monohydrate.
Pramipexole dihydrochloride monohydrate belongs to a group of medicines known as "dopamine agonists", which bind to dopamine receptors.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
SIMPRAL is not addictive.
This medicine is available only with a doctor's prescription.
SIMPRAL is not recommended for use in children under 18 years of age as its safety and effectiveness in that age group have not been established.

How to take SIMPRAL
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
The usual dose is one tablet a day. Depending on how you respond to the treatment, your doctor may suggest a higher or lower dose.
Follow all directions given to you by your doctor or pharmacist carefully.
How to take it
Swallow the tablets whole with a full glass of water.
When to take it
Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.
How long to take it
Continue taking your medicine for as long as your doctor tells you to. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much SIMPRAL. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include nausea, vomiting, abnormal uncontrolled movements, hallucinations, agitation and dizziness or light-headedness.
While you are taking SIMPRAL
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking SIMPRAL.
Tell any other doctors, dentists and pharm
ists who treat you that you are taking this medicine.
If you feel that SIMPRAL is not helping your condition, tell your doctor or pharmacist.
Tell your doctor if, for any reason, you have not used SIMPRAL exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.
Tell your doctor as soon as possible if there is any worsening of your condition.
If you or your family notices an increase in compulsive behaviour, seek immediate medical advice.
Tell your doctor if you experience symptoms such as depression, apathy, anxiety, fatigue, sweating or pain after stopping or reducing your Simpral treatment. If the problems persist for more than a few weeks, your doctor may need to adjust your treatment.
Tell your doctor if you develop an inability to keep your body and neck straight and upright. For example, you may experience abnormal posture such as forward bending of the head and neck, forward bending of the lower back or sidewards bending of the back
Things you must not do
Do not take SIMPRAL to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor. It is important not to suddenly stop taking your SIMPRAL tablets, unless advised to do so by your doctor, since your condition may worsen.
If your doctor asks you to stop taking SIMPRAL, the dose will normally need to be reduced gradually over several days.
Things to be careful of
Be careful driving or operating machinery until you know how SIMPRAL affects you. This medicine may cause drowsiness, hallucinations and episodes of sudden onset of sleep, in some people.
Make sure you know how you react to SIMPRAL before you engage in any activities where impaired alertness may put yourself or others at risk of serious injury.
If you experience excessive drowsiness or an episode of sudden onset of sleep (while performing daily activities), do not drive or perform any potentially dangerous activities, and contact your doctor.
Be careful when drinking alcohol while you are taking this medicine.
Combining SIMPRAL and alcohol can make you more drowsy or sleepy.
Be careful getting up from a sitting or lying position. You may feel dizzy or lightheaded while taking SIMPRAL, especially during the first few weeks of treatment. If you wish to stand up, you should do so slowly.
Patients with Parkinson's Disease may have an increased risk of developing melanoma.
You should monitor your skin and see your doctor in case of any concerns.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SIMPRAL.
SIMPRAL helps most people with Parkinson's disease, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by the following list of side effects. You may not experience any of them.
