Generic name: safinamide [sa-FIN-a-mide]
Dopaminergic antiparkinsonism drugs are a type of drug.

What is Xadago?

MAO-B is the type of inhibitor that Xadago is. This medicine works by letting a chemical called dopamine (pronounced “doe-pa-meen”) stay active in the brain for longer. Parkinson’s disease is linked to a lack of dopamine in the brain.

People with Parkinson’s disease are given Xadago along with levodopa and carbidopa to treat “wearing-off” events, which include stiff muscles and a loss of control over the muscles.


If your liver disease is very bad, you should not take Xadago.

TELL YOUR DOCTOR ABOUT EVERYTHING ELSE YOU TAKE. Some drugs can make you feel sick or even kill you if you take them within 14 days of taking Xadago.

This medicine can be taken with or without food.

People will need to check your blood pressure often.

Information dosage

Normal dose for an adult with Parkinson’s disease:

Initial dose: 50 mg once a day by mouth

Maintenance amount: After two weeks, the dose can be raised to 100 mg orally once a day, depending on the person’s needs and how well they handle it.

Maximum dose: 100 mg per day

Comment: It hasn’t been shown that higher amounts are more helpful, but they do increase the risk of side effects.

-This medicine has only been shown to work when used with levodopa/carbidopa.

Use: Along with levodopa/carbidopa to help people with Parkinson’s disease who are having “off” episodes.

What will happen if I don’t take a dose?

As soon as you remember, take the dose you forgot. If it’s almost time for your next dose, don’t take the one you missed. Do not take more medicine than usual to make up for the dose you missed.

What happens if I overdose?

What not to do

You shouldn’t eat foods high in tyramine while taking Xadago and for 14 days after you stop. These foods include pickled foods (like eggs or herring) and aged, salted, smoked, or fermented meats.

If you take safinamide and eat tyramine at the same time, it can raise your blood pressure to dangerous levels, which could lead to side effects that could kill you. While you are taking Xadago, you should become very familiar with the list of things you should not eat.

Some people who took this medicine fell asleep while working, driving, or doing other physical tasks during the day. Don’t drive or use equipment until you know how this medicine will make you feel.
