Patient leaflet - Rasagiline Relonchem 1 mg tablets

1. What Rasagiline is and what it is used for

Rasagiline contains the active substance Rasagiline (as mesylate) and it is used for the treatment of Parkinson’s disease in adults. It can be used together with or without Levodopa (another medicine that is used to treat Parkinson’s disease).

With Parkinson’s disease, there is a loss of cells that produce dopamine in the brain. Dopamine is a chemical in the brain involved in movement control. Rasagiline helps to increase and sustain levels of dopamine in the brain.

2. What you need to know before you take Rasagiline

Do not take Rasagiline

  • If you are allergic to Rasagiline or any of

    the other ingredients of this medicine (listed in section 6).

  • If you have severe liver problems.

Do not take the following medicines while taking Rasagiline:

  • Monoamine oxidase (MAO) inhibitors (e.g. for treatment of

    depression or Parkinson’s disease, or used for any other indication), including medicinal and natural products without prescription e.g. St. John's Wort.

  • Pethidine (a strong pain killer).

You must wait at least 14 days after stopping Rasagiline treatment and starting treatment with MAO inhibitors or pethidine.

Warnings and precautions

Talk to your doctor before taking Rasagiline

  • If you have any liver problems.
  • You should speak with your doctor about any suspicious skin

    changes. Treatment with Rasagiline may possibly increase the risk of skin cancer.

Tell your doctor if you or your family/carer notices that you are developing unusual behaviours where you cannot resist the impulse, urges or cravings to carry out certain harmful or detrimental activities to yourself or others. These are called impulse control disorders. In patients taking Rasagiline and/or other medicines used to treat Parkinson’s disease, behaviours such as compulsions, obsessive thoughts, addictive gambling, excessive spending, impulsive behaviour and an abnormally high sex drive or an increase in sexual thoughts or feelings have been observed. Your doctor may need to adjust or stop your dose (see section 4).

Rasagiline may cause drowsiness and may cause you to suddenly fall asleep during daytime activities, especially if you are taking other dopaminergic medicinal products (used for the treatment of Parkinson’s disease). For further information please refer to section driving and using machines.

Children and adolescents

There is no relevant use of Rasagiline in children and adolescents.

Therefore, Rasagiline is not recommended for use under the age of 18.

Other medicines and Rasagiline

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Especially tell your doctor if you are taking any of the following medicines:

  • Certain antidepressants (selective serotonin reuptake inhibitors, selective serotonin-norepinephrine reuptake inhibitors, tricyclic or tetracyclic antidepressants).
  • The antibiotic ciprofloxacin used against infections.
  • The cough suppressant dextromethorphan.
  • Sympathomimetics such as those present in eye drops, nasal and oral decongestants and cold medicine containing ephedrine or pseudoephedrine.

The use of Rasagiline together with the antidepressants containing fluoxetine or fluvoxamine should be avoided.

If you are starting treatment with Rasagiline, you should wait at least 5 weeks after stopping fluoxetine treatment.

If you are starting treatment with fluoxetine or fluvoxamine, you should wait at least 14 days after stopping Rasagiline treatment.

Tell your doctor or pharmacist if you are smoking or intend to stop smoking. Smoking could decrease the amount of Rasagiline in the blood.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

You should avoid taking Rasagiline if you are pregnant, as the effects of Rasagiline on pregnancy and the unborn child are not known.

Driving and using machines

Ask your doctor for advice before you drive

and operate machines, since Parkinson’s

disease itself as well as the treatment with

Rasagiline may influence your ability to do so.

Rasagiline can make you feel dizzy or drowsy;

it can also cause episodes of sudden sleep

onset.

This might be enhanced if you take other medicines to treat the symptoms of your Parkinson’s disease, or if you take medicines which can make you feel drowsy, or if you drink alcohol while taking Rasagiline. If you have experienced somnolence and/or episodes of sudden sleep onset before, or while taking Rasagiline do not drive or operate machinery (see section 2).

3. How to take Rasagiline

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose of Rasagiline is 1 tablet of 1 mg taken by mouth once daily. Rasagiline may be taken with or without food.

If you take more Rasagiline than you should

If you think that you may have taken too many Rasagiline tablets, contact your doctor or pharmacist immediately. Take the Rasagiline carton/ blister with you to show the doctor or pharmacist.

Symptoms reported following overdose of Rasagiline included slightly euphoric mood (light form of mania), extremely high blood pressure and serotonin syndrome (see section 4).

If you forget to take Rasagiline

Do not take a double dose to make up for a forgotten dose. Take the next dose normally, when it is time to take it.

If you stop taking Rasagiline

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