本文发表在 rolia.net 枫下论坛Three antiviral drugs (amantadine, rimantadine, and oseltamivir) are approved and commercially available for use in preventing flu. All of these medications are prescription drugs, and a doctor should be consulted before the drugs are used. When used for prevention, they are about 70% to 90% effective for preventing illness in healthy adults.

Four antiviral drugs (amantadine, rimantadine, zanamavir and oseltamivir) have been approved for treatment of the flu. If taken within 2 days of getting sick, these drugs can reduce the symptoms of the flu and shorten the time you are sick by 1 or 2 days. They also can make you less contagious to others. All of these drugs must be prescribed by a doctor and taken for 5 days. Antiviral drugs are effective only against influenza viruses. They will not help the symptoms associated with the common cold or many other flu-like illnesses caused by viruses that circulate in the winter.

All of the antiviral drugs are different in terms of who can take them, how they are given, any dosing changes based on age or medical conditions, and side effects. Your doctors will help decide whether you should get antivirals and which one you should get.更多精彩文章及讨论，请光临枫下论坛 rolia.net
