Serious Swine Flu Symptoms:

Fast breathing or trouble breathing
Bluish or gray skin color
Not drinking enough fluids
Severe or persistent vomiting
Not waking up or not interacting
Being so irritable, one does not want to be held
Flu-like symptoms improve but then return with fever and worse cough

Swine Flu Treatments :
As with the regular seasonal flu, antiviral flu medications, including Tamiflu (oseltamivir) and Relenza (zanamivir), are available to prevent and treat the swine flu.
What makes this confusing is that there were many reports this past flu season that the seasonal flu virus was resistant to Tamiflu. In fact, it was recommended that doctors go back to using older medicines like Symmetrel (amantadine) or Flumadine (rimantadine) with Tamiflu or Relenza instead, if someone had a seasonal influenza A (H1N1) virus infection.
In contrast, the swine influenza A (H1N1) virus seems to be resistant to older medications, but still sensitive to Tamiflu and Relenza.
