Is there medicine that can prevent or treat pandemic flu? How effective is it?
There are medicines, called antivirals, approved for use in the U.S. to prevent and treat flu. These antiviral medicines fight many kinds of flu. Health experts think antivirals could provide some protection against pandemic flu but it will depend on the virus. Antivirals are most effective when used as soon as possible after symptoms appear. The federal government has a national stockpile of antiviral medicines. Despite the stockpiling effort, there may not be enough for everyone.
