Many influenza viruses have become resistant to the effects of a category of antiviral drugs that includes amantadine and rimantadine (Flumadine). Health officials recommend the use of oseltamivir (Tamiflu) or, if oseltamivir can't be used, zanamivir (Relenza). These drugs must be taken within two days after the appearance of symptoms.
There is concern, however, that some types of bird flu may be developing resistance to oseltamivir. Chinese health officials have developed another type of flu medication that received accelerated approval from their government for the treatment of H7N9 bird flu.
