Amantadine may provide some limited improvement in ataxic symptoms, but is not recommended in children with cardiac abnormalities.
Amantadine and acyclovir may be helpful against certain viral pneumonias.
They include amantadine (Symmetrel, Symadine) and rimantadine (Flumandine), which work against Type A influenza, and zanamavir (Relenza) and oseltamavir phosphate (Tamiflu), which work against both Types A and B influenza.
Amantadine and rimantadine can cause side effects such as nervousness, anxiety, lightheadedness, and nausea.
As an alternative, they may receive a course of amantadine or rimantadine, which are also used as a protective measure against influenza.
