You should not use amantadine if you received a nasal flu vaccine in the past 14 days.
Do not receive a nasal flu vaccine while taking amantadine, and for at least 48 hours after your last dose. You may receive a flu shot (injection) while taking amantadine.
Avoid driving and doing other tasks or actions that call for you to be alert or have clear eyesight until you see how this amantadine affects you.
To lower the chance of feeling dizzy or passing out, rise slowly if you have been sitting or lying down. Be careful going up and down stairs.
Heat stroke has happened in people taking amantadine. Be careful in hot weather and during physical activity.
If you have kidney problems, talk with your doctor. Your dose may need to be changed based on how well your kidneys work. Deaths have happened in people with kidney problems whose dose was too high for their kidney function.
Do not stop taking amantadine all of a sudden without calling your doctor. You may have a greater risk of side effects. If you need to stop amantadine, you will want to slowly stop it as ordered by your doctor.
