How does this medication work? What will it do for me?
Rasagiline belongs to the family of medications known as monoamine oxidase inhibitors (MAOIs). It is used to treat Parkinson’s disease. It acts on the nervous system to increase the levels of a chemical called dopamine. Low dopamine levels in the brain are responsible for many of the symptoms of Parkinson’s disease, so this medication works by rebalancing the levels of dopamine.
This medication may be taken alone or in combination with levodopa or a dopamine agonist (i.e., ropinirole, pramipexole) to treat the symptoms of Parkinson’s disease.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Antidepressant medication: Severe reactions are possible when rasagiline is combined with medications and natural products used to treat depression. Avoid combining rasagiline and antidepressants. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, and changes in mental state including delirium and agitation. Coma and death are also possible.
If you have taken antidepressants recently, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Behaviour changes: People taking rasagiline have experienced abnormal behaviour such as compulsive gambling, compulsive shopping, hypersexuality, and binge eating. If you experience these symptoms or any other behaviour change while taking this medication, contact your doctor immediately.
Kidney function: Rasagiline should not be used by people with moderate or severe kidney function impairment. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function impairment: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. People with mild liver function impairment may be given 0.5 mg of rasagiline daily. Do not take rasagiline if you have moderate or severe liver function impairment.
Skin cancer: People taking this medication have a higher risk of developing skin cancer. It is unclear whether this increased risk is due to Parkinson’s disease or to rasagiline. You and your doctor should check your skin regularly for signs of skin cancer (e.g., moles that have an irregular shape or border, moles that change colour, or moles that are larger than 6 mm).

Be careful if driving or operating machinery while taking this medication.
