This medicine 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. Safinamide 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, Safinamide is added to a stable dose of the medicine called levodopa alone or in combination with other medicines for Parkinson’s disease.
Talk to your doctor before taking Safinamide
Safinamide is not recommended for use in children and adolescents, below 18 years old due to the lack of data on safety and efficacy in this population.
Tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines. Ask your doctor for advice before taking any of the following medicines together with Safinamide:
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
Pregnancy
Safinamide should not be used during pregnancy or by women of childbearing potential not practicing adequate contraception.
Breast Feeding
Safinamide is likely to be excreted in breast milk. Safinamide should not be used during breast feeding.
