Hi...Thank you for consulting in Health Care magic.
Red bumps could be a toxic
urticaria or
allergy due to fever.
Fever of one day without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If she is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all.
Once
viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active.
Paracetamol can be given in the dose of 15mg/kg/dose every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
