Symmetrel (Amantadine)

Zovirax (Acyclovir) is used to treat infections caused by certain types of viruses. It treats cold sores around the mouth (caused by herpes simplex), shingles (caused by herpes zoster), and chickenpox. This medication is also used to treat outbreaks of genital herpes. In people with frequent outbreaks, acyclovir is used to help reduce the number of future episodes. Acyclovir is an antiviral drug.

Symmetrel (Amantadine) may not be appropriate for treating or preventing all cases of the flu, depending on which virus is causing the infection. Amantadine does not work against all influenza viruses. Influenza A viruses in some locations may have developed resistance to amantadine, which will make it less effective. Amantadine works as an antiviral by blocking the activity of a specific protein in certain viruses they need to multiply and spread in the body. Amantadine may help relieve Parkinson’s symptoms or treat drug-induced movement problems by acting like dopamine in the brain to control movements.
