Amantadine and Rimantadine for Influenza

These anti-viral medications have been available for decades, and are useful in the treatment and prevention of influenza A infection, but not for influenza B. For these medications to be effective, they need to be taken within 48 hours of the start of influenza symptoms, and are typically taken for 5 days, or for 24 to 48 hours after influenza symptoms go away.

Amantadine and rimantidine probably work by preventing the influenza virus from infecting and replicating inside the cells of a person’s respiratory tract. Side effects of these medications can be severe and often limit their use; rimantadine tends to have less severe side effects than amantadine.
