Patient Education

Amantadine


Amantadine is used to treat the symptoms of Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance) and other similar conditions. It is also used to control movement problems that are a side effect of certain medications used to treat Parkinson's disease. Amantadine extended-release capsules (Gocovri) are used along with the combination of levodopa and carbidopa (Rytary, Sinemet) to treat ''off'' episodes (times of difficulty moving, walking, and speaking that may happen when other medications wear off) in people with Parkinson's disease. It also is used to prevent symptoms of influenza A virus infection and for treatment of respiratory infections caused by influenza A virus. Amantadine is in a class of medications called adamantanes. It is thought to work to control movement problems by increasing the amount of dopamine in certain parts of the body. It works against influenza A virus by stopping the spread of the virus in the body.
