What Sifrol is used for
Sifrol is used to treat the symptoms of Parkinson's disease and Restless Legs Syndrome (RLS).
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.
RESTLESS LEGS SYNDROME (RLS)
RLS is a neurological disorder in which there is an overwhelming urge to move the legs to stop unpleasant sensations.
The sensations vary from person to person and range from uncomfortable to irritating to painful. The symptoms usually occur when sitting or lying down - which often leads to problems falling or staying asleep. Sometimes the arms and body may be affected. Current evidence suggests that RLS may be due to faulty dopamine signals in certain areas of the brain.
How Sifrol works
Sifrol contains the active ingredient pramipexole hydrochloride monohydrate. It belongs to a group of medicines known as dopamine agonists, which bind to dopamine receptors. It is believed that Sifrol works by having a similar effect as dopamine in the brain.
Ask your doctor if you have any questions about why Sifrol has been prescribed for you.
Your doctor may have prescribed it for another reason.
Sifrol is not addictive.
This medicine is available only with a doctor's prescription.

How to take Sifrol
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
Sifrol is available in a number of tablet strengths. Your doctor or pharmacist will tell you which strength of Sifrol tablet and 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 dose varies from patient to patient. Your doctor may first start you on a low dose of Sifrol and slowly increase the amount of Sifrol until the right dose is reached to control your condition.
The usual starting dose is one Sifrol 0.125 mg tablet three times a day.
Depending on how you respond to the treatment, your doctor may increase your daily dose gradually in steps of 0.75 mg at weekly intervals until the right dose for your needs is reached. The maximum dose is 4.5 mg of Sifrol per day.
RESTLESS LEGS SYNDROME
The usual starting dose is one Sifrol 0.125 mg tablet once a day, usually 2 to 3 hours before you go to bed.
Depending on how you respond to the treatment, your doctor may increase your dose gradually every 4 to 7 days until the right dose for your needs is reached. The maximum dose is 0.75 mg of Sifrol per day.
Follow all directions given to you by your doctor or pharmacist carefully.
How to take it
Swallow the tablets with a full glass of water.
Sifrol can be taken with or without food.
When to take it
Take Sifrol 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 Sifrol 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.
RESTLESS LEGS SYNDROME
If you forget to take Sifrol before you go to bed and you wake up late in the night or early morning, do not take any Sifrol as you may have trouble waking in the morning.
Skip the dose you missed and take the next dose when you are meant to.
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, pharmacist or Poisons Information Centre (telephone 13 11 26) for advice, or go to Emergency at your nearest hospital if you think that you or anyone else may have taken too much Sifrol. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Sifrol you may have nausea, vomiting, abnormal uncontrolled movements, hallucinations, agitation and dizziness or light-headedness.
