What is it and how is it used?

SIFROL belongs to a group of medicines known as dopamine agonists, which stimulate dopamine receptors in the brain. Stimulation of the dopamine receptors triggers nerve impulses in the brain that help to control body movements.

SIFROL is used to treat the symptoms of primary Parkinson?s disease. It can be used alone or in combination with levodopa (another medicine for Parkinson?s disease).

What do you have to consider before using it?

Do not take SIFROL
  • if you are allergic (hypersensitive) to pramipexole or to any of the other ingredients of the tablets (see Section 6, ?Further information?).

Take special care with SIFROL

Tell your doctor if you have (had) or develop any medical conditions or symptoms, especially any of the following:

  • Kidney disease.
  • Hallucinations (seeing, hearing or feeling things that are not there). Most hallucinations are visual.
  • Dyskinesia (e.g. abnormal, uncontrolled movements of the limbs). If you have advanced Parkinson?s disease and are also taking levodopa, you might develop dyskinesia during the up-titration of SIFROL.
  • Sleepiness and episodes of suddenly falling asleep.
  • Behavioural changes (e.g. pathological gambling, compulsive shopping), increased libido (e.g. increased sexual desire), binge eating.
  • Psychosis (e.g. comparable with symptoms of schizophrenia).
  • Vision impairment. You should have regular eye examinations during treatment with SIFROL.
  • Severe heart or blood vessels disease. You will need to have your blood pressure checked regularly, especially at the beginning of treatment. This is to avoid postural hypotension (a fall in blood pressure on standing up).
Children and adolescents

SIFROL is not recommended for use in children or adolescents under 18 years.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines, herbal remedies, health foods or supplements that you have obtained without a prescription.

You should avoid taking SIFROL together with antipsychotic medicines.

Take care if you are taking the following medicines:

  • cimetidine (to treat excess stomach acid and stomach ulcers);
  • amantadine (which can be used to treat Parkinson?s disease);
  • mexiletine (to treat irregular heartbeats, a condition known as ventricular arrhythmia);
  • zidovudine (which can be used to treat the acquired immune deficiency syndrome (AIDS), a disease of the human immune system);
  • cisplatin (to treat various types of cancers);
  • quinine (which can be used for the prevention of painful night-time leg cramps and for the treatment of a type of malaria known as falciparum malaria (malignant malaria));
  • procainamide (to treat irregular heart beat).

If you are taking levodopa, the dose of levodopa is recommended to be reduced when you start treatment with SIFROL.

Take care if you are using any medicines that calm you down (have a sedative effect) or if you are drinking alcohol. In these cases SIFROL may affect your ability to drive and operate machinery.

Taking SIFROL with food and drink

You should be cautious while drinking alcohol during treatment with SIFROL.
SIFROL can be taken with or without food.

Pregnancy and breast-feeding

Tell your doctor if you are pregnant, think you might be pregnant or if you intend to become pregnant. Your doctor will then discuss with you if you should continue to take SIFROL.

The effect of SIFROL on the unborn child is not known. Therefore, do not take SIFROL if you are pregnant unless your doctor tells you to do so.

SIFROL should not be used during breast-feeding. SIFROL can reduce the production of breast milk. Also, it can pass into the breast milk and can reach your baby. If use of SIFROL is unavoidable, breast-feeding should be stopped.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

SIFROL can cause hallucinations (seeing, hearing or feeling things that are not there). If affected, do not drive or use machines.

SIFROL has been associated with sleepiness and episodes of suddenly falling asleep, particularly in patients with Parkinson?s disease. If you experience these side effects, you must not drive or operate machinery. You should tell your doctor if this occurs.

How is it used?

Always take SIFROL exactly as your doctor has told you. The doctor will advise you on the right dosing.

Take SIFROL prolonged-release tablets only once a day and each day at about the same time.

You can take SIFROL with or without food. Swallow the tablets whole with water.

Do not chew, divide or crush the prolonged-release tablets. If you do, there is a danger you could overdose, because the medicine may be released into your body too quickly.

During the first week, the usual daily dose is 0.26 mg pramipexole. The dose will be increased every 5-7 days as directed by your doctor until your symptoms are controlled (maintenance dose).

Ascending dose schedule of SIFROL prolonged-release tablets Week Daily dose mg Number of tablets 1 0.26 One SIFROL 0.26 mg prolonged-release tablet. 2 0.52 One SIFROL 0.52 mg prolonged-release tablet, OR two SIFROL 0.26 mg prolonged-release tablets. 3 1.05 One SIFROL 1.05 mg prolonged-release tablet, OR two SIFROL 0.52 mg prolonged-release tablets, OR four SIFROL 0.26 mg prolonged-release tablets.

The usual maintenance dose is 1.05 mg per day. However, your dose may have to be increased even further. If necessary, your doctor may increase your dose up to a maximum of 3.15 mg of pramipexole a day. A lower maintenance dose of one SIFROL 0.26 mg prolonged-release tablet a day is also possible.

Patients with kidney disease

If you have kidney disease, your doctor may advise you to take the usual starting dose of 0.26 mg prolonged-release tablets only every other day for the first week. After that, your doctor may increase the dosing frequency to one 0.26 mg prolonged-release tablet every day. If a further dose increase is necessary, your doctor may adjust it in steps of 0.26 mg pramipexole.

If you have serious kidney problems, your doctor may need to switch you to a different pramipexole medicine. If during treatment your kidney problems get worse, you should contact your doctor as soon as possible.

If you are switching from SIFROL (immediate release) tablets

Your doctor will base your dose of SIFROL prolonged-release tablets on the dose of SIFROL (immediate release) tablets you were taking.

Take your SIFROL (immediate release) tablets as normal the day before you switch. Then take your SIFROL prolonged-release tablets next morning and do not take any more SIFROL (immediate release) tablets.

If you take more SIFROL than you should

If you accidentally take too many tablets,

  • Contact your doctor or nearest hospital casualty department immediately for advice.
  • You may experience vomiting, restlessness, or any of the side effects as described in chapter 4 ?Possible side effects?.

If you forget to take SIFROL

If you forget to take a dose of SIFROL, but remember within 12 hours of your usual time, take your tablet straightaway and then take your next tablet at the usual time.
If you forget for more than 12 hours, simply take the next single dose at the usual time. Do not take a double dose to make up for a forgotten tablet dose.

If you stop taking SIFROL

Do not stop taking SIFROL without first talking to your doctor. If you have to stop taking this medicine, your doctor will reduce the dose gradually. This reduces the risk of worsening symptoms.

If you suffer from Parkinson?s disease you should not stop treatment with SIFROL abruptly. A sudden stop could cause you to develop a medical condition called neuroleptic malignant syndrome which may represent a major health risk. The symptoms include:

  • akinesia (loss of muscle movement),
  • rigid muscles,
  • fever,
  • unstable blood pressure,
  • tachycardia (increased heart rate),
  • confusion,
  • depressed level of consciousness (e.g. coma).

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