Do not receive a nasal flu vaccine while using amantadine, and for at least 48 hours after your last dose. The vaccine may not work as well during this time, and may not protect you from influenza. You may receive a flu shot (injection) while taking amantadine.
Do not drink alcohol. Dangerous side effects could occur.
Avoid driving or operating machinery until you know how amantadine will affect you. Amantadine may impair your thinking or reactions. Some people taking this medicine have fallen asleep during normal daytime activities such as working, talking, eating, or driving. You may fall asleep suddenly, even after feeling alert. Be careful if you drive or do anything that requires you to be alert.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy.
Avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor's advice. Taking a stimulant together with amantadine can increase your risk of unpleasant side effects.
