AMANTADINE prevents and treats infections caused by the
flu virus (
influenza). It works by slowing the spread of the
flu virus in your body and reducing how long your symptoms last. It will not treat
colds or infections caused by bacteria or other viruses. It will not replace the annual
flu vaccine. It may also be used to treat movement disorders, including those caused by
Parkinson disease and some medications. It works by balancing substances in your brain that help manage body movements and coordination. This reduces symptoms, such as body stiffness and
tremors.
