Suggest Medication For Flu Followed By Headaches & Blurred Vision

My daughter was diagnosed with flu 2 days ago and given antibiotics. 2 days later she has barely eaten, feels sick (stomach) intense headaches where she says she has blurred vision and finds it hard to focus, sore throat, occassional cough and is now complaining of numb fingers, dificulty breathing, being freezing when she feels extremely hot yet her hands are numb and is completely exhausted. I am from nz and it is 1:13am, is it worth taking her to the hopital??
