What SIMIPEX XR is used for
SIMIPEX XR is 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 binds to dopamine receptors and relays messages in the part of the brain that controls movement. When too little dopamine is produced, this results in Parkinson's disease. SIMIPEX XR works by having a similar effect as dopamine in the brain.
How SIMIPEX XR works
SIMIPEX XR 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 SIMIPEX XR has been prescribed for you. Your doctor may have prescribed SIMIPEX XR for another reason.
SIMIPEX XR is not addictive.
This medicine is available only with a doctor's prescription.
Use in children
SIMIPEX XR 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 SIMIPEX XR
Follow all directions given to you by your doctor or 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 label, 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. They may differ from the information contained in this leaflet.
If you are switching from the immediate-release pramipexole tablets:
Your doctor will base your dose of SIMIPEX XR tablets on the dose of the immediate-release Pramipexole tablets you were taking.
Take your immediate-release Pramipexole tablets as normal the day before you switch. Then take your modified release SIMIPEX XR tablets the next morning and do not take any more of the immediate-release Pramipexole tablets.
How to take it
Swallow the tablet whole with a full glass of water.
Do not chew, divide or crush SIMIPEX XR.
SIMIPEX XR tablets can be taken with or without food.
When to take it
Take SIMIPEX XR 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.
How long to take it
Continue taking SIMIPEX XR for as long as your doctor tells you. 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 the next dose when you are meant to.
Otherwise, take it as soon as you remember, then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you have 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 use your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor, pharmacist or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much SIMIPEX XR. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much SIMIPEX XR you may have nausea, vomiting, abnormal uncontrolled movements, hallucinations, agitation and dizziness or light-headedness.
While you are taking SIMIPEX XR
Things you must do
Tell all doctors and pharmacists who are treating you that you are taking SIMIPEX XR.
If you feel that SIMIPEX XR is not helping your condition, tell your doctor or pharmacist.
Tell your doctor if, for any reason, you have not used SIMIPEX XR 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 notice parts of SIMIPEX XR tablets in your stool (faeces). This may look like whole tablets. Your doctor may need to assess your response to therapy.
Tell your doctor if you experience symptoms such as depression, apathy, anxiety, fatigue, sweating or pain after stopping or reducing your SIMIPEX XR 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 give SIMIPEX XR to anyone else, even if they have the same condition as you.
Do not stop taking SIMIPEX XR or change the dose without checking with your doctor. It is important not to suddenly stop taking your SIMIPEX XR tablets, unless advised to do so by your doctor, since your condition may worsen.
If your doctor asks you to stop taking SIMIPEX XR, 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 SIMIPEX XR 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 SIMIPEX XR 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 taking SIMIPEX XR. Combining SIMIPEX XR 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 SIMIPEX XR, 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 SIMIPEX XR.
SIMIPEX XR 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 these lists of possible side effects. You may not experience any of them.
