Amantadine is an antiviral medicine that blocks the actions of viruses in your body.
Amantadine is used to treat Parkinson's disease and "Parkinson-like" symptoms such as stiffness or tremors, shaking, and repetitive uncontrolled muscle movements that may be caused by the use of certain drugs.
Amantadine is also used to treat or prevent influenza A in adults and children. It may not be effective during every flu season because certain strains of the virus may be resistant to amantadine. This medicine should not be used in place of getting a yearly flu shot. The Centers for Disease Control recommends an annual flu shot to help protect you each year from new strains of influenza virus.
Amantadine is available as tablets, capsules, and oral solution.
