Thought I would post the outcome in case anyone in a similar situation references this page in the future.

DD was not able to have a Swine Flu swab test performed, as she had already commenced the Tamiflu. It was agreed I should go on Relenza as a precautionary measure. Meanwhile DD is still out of sorts, but improving. We all got a little more shuteye last night

DD had been challenged with her initial prescription of Relenza, which is why she was switched to Tamiflu. She could not get the hang of the puffer. Now I am embarrassed to say I don't think I am doing an entirely good job of it either. I even watched the video on the Relenza website. But somehow, despite my best conscious efforts, more seems to go on my tongue, than down into my lungs where it should go The good news is that I still do not have a fever and I think we may be getting past DD's most infectious stage
