1. What Xadago is and what it is used for

Xadago is a medicine that contains the active substance safinamide. It acts to increase the level of a substance called dopamine in the brain, which is involved in the control of movement and is present in reduced amounts in the brain of patients with Parkinson’s disease. Xadago is used for the treatment of Parkinson’s disease in adults.

In mid- to late-stage patients experiencing sudden switches between being “ON” and able to move and being “OFF” and having difficulties moving about, Xadago is added to a stable dose of the medicine called levodopa alone or in combination with other medicines for Parkinson’s disease.

2. What you need to know before you take Xadago

Do not take Xadago

  • If you are allergic to safinamide or any of the other ingredients of this medicine (listed in section 6).
  • If you are taking any of the following medicines:
    • Monoamine oxidase (MAO) inhibitors such as selegiline, rasagiline, moclobemide, phenelzine, isocarboxazid, tranylcypromine (e.g. for treatment of Parkinson’s disease or depression, or used for any other condition).
    • Pethidine (a strong pain killer).
    You must wait at least 7 days after stopping Xadago treatment before starting treatment with MAO inhibitors or pethidine.
  • If you have been told that you have severe liver problems
  • If you have an eye condition which might put you at risk of potential damage to your retina (the light sensitive layers at the back of your eyes), e.g. albinism (lack of pigment in your skin and eyes), retinal degeneration (loss of cells from light sensitive layer at the back of the eye), or uveitis (inflammation inside of the eye), inherited retinopathy (inherited disorders of the vision), or severe progressive diabetic retinopathy (a progressive decrease of the vision due to diabetes).

  • Patients and carers should be made aware that certain compulsive behaviours such as compulsions, obsessive thoughts, pathological gambling, increased libido, hypersexuality, impulsive behaviour and compulsive spending or buying have been reported with other medicines for Parkinson’s disease.
  • Uncontrollable jerky movements may occur or worsen when Xadago is used together with levodopa.
