Indications
Xadago (generically known as safinamide) is a prescription medication indicated to treat symptoms of Parkinson's disease. It can help improve symptoms such as shakiness, stiffness, and difficulty moving. It is given with levodopa and carbidopa to treat "wearing-off" episodes (muscle stiffness, loss of muscle control) in people with Parkinson's disease.
Safinamide belongs to a class of drugs known monoamine oxidase type B (MAO-B) inhibitor and works by blocking an enzyme in the brain that breaks down dopamine, a substance that helps regulate movement in the body. It works by increasing the levels of certain natural substances in the brain (such as dopamine). Parkinson's disease is thought to be caused by too little dopamine in the brain.
Uses and Dosage
Xadago is typically taken in tablet form by mouth, either with or without food as directed by your doctor, usually once daily. The dosage is based on your medical condition and how you respond to treatment. Do not increase your dose or take it more often than prescribed, as doing so will not improve your condition any faster and may increase your risk of side effects.
To get the most benefit from Xadago, take it regularly and at the same time each day. Do not stop taking this medication without consulting your doctor, as some conditions may worsen if the drug is stopped suddenly. Your doctor may gradually decrease your dose if necessary.
Eating a large amount of tyramine while taking safinamide, and for 2 weeks after stopping it, may cause a rare, but serious, high blood pressure reaction. Patients should avoid consuming foods high in tyramine, such as aged cheeses like Stilton cheese, and consult their doctor or dietician about which other foods to avoid. If feeling unwell after eating or drinking certain foods while taking this medication, seek medical advice. See also the Side Effects section for further information.
