Mary - the evidence for any effect from Tamiflu is fairly shaky. If given with 48 hours may shorten duration of symptoms by 1 day. No evidence of any additional benefit in swine flu although the DOH and our CMO seem to pushing it as a miracle pill that will cure everyone and should be given to everyone with a cough and temperature. A medline search reveals no data on evidence of effectiveness after 48 hours.
