Is her cough normal with swine flu?

i have a little girl who is almost 2 and she has just been diagnosed with swine flu and has started taking tamiflu., for a while now she has had a nasty cough and she is asthmatic but the last few days it seems to have got worse! she has no Temperature but is not eating properly and cannot stop coughing even after taking her inhaler its even got to the stage where she has made herself sick from constant coughing!! can anyone tell me if im just being paranoid or should i be concerned
