What Sifrol ER is used for

Sifrol ER 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. Sifrol ER works by having a similar effect as dopamine in the brain.

How Sifrol ER works

Sifrol ER contains the active ingredient pramipexole hydrochloride monohydrate. It 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 Sifrol ER has been prescribed for you. Your doctor may have prescribed it for another reason.

Sifrol ER is not addictive.

This medicine is available only with a doctor's prescription.

How to take Sifrol ER

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 Sifrol tablets: Your doctor will base your dose of Sifrol ER tablets on the dose of the immediate-release Sifrol tablets you were taking.

Take your immediate-release Sifrol tablets as normal the day before you switch. Then take your extended-release Sifrol ER tablets the next morning and do not take any more of the immediate-release Sifrol tablets.

How to take it

Swallow the tablet whole with a full glass of water.

Do not chew, divide or crush Sifrol ER.

Sifrol ER tablets can be taken with or without food.

When to take it

Take Sifrol ER 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 ER 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 Emergency at your nearest hospital if you think that you or anyone else may have taken too much Sifrol ER. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much Sifrol ER you may have nausea, vomiting, abnormal uncontrolled movements, hallucinations, agitation and dizziness or light-headedness.

While you are taking Sifrol ER

Things you must do

Tell all doctors and pharmacists who are treating you that you are taking Sifrol ER.

Tell your doctor or pharmacist if you feel that Sifrol ER is not helping your condition.

Tell your doctor if, for any reason, you have not used Sifrol ER 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.

Things you must not do

Do not give Sifrol ER to anyone else, even if they have the same condition as you.

Do not stop taking Sifrol ER or change the dose without checking with your doctor. It is important not to suddenly stop taking your Sifrol ER tablets, unless advised to do so by your doctor, since your condition may worsen.

If your doctor asks you to stop taking Sifrol ER, 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 Sifrol ER 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 Sifrol ER 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 Sifrol ER. Combining Sifrol ER and alcohol can make you more drowsy or sleepy.

Be careful getting up from a sitting or lying position. You may feel dizzy or light-headed while taking Sifrol ER, especially during the first few weeks of treatment. If you wish to stand up, you should do so slowly.

You should monitor your skin and see your doctor in case of any concerns. Patients with Parkinson's disease may have an increased risk of developing melanoma.
