Hi Neel,
Too bad that the antibiotics are not helping your father - perhaps other types of antibiotics could have better effect. It is very common that they never find the agent (bacteria, virus or fungi) that causes the fever so that they have to try different antibiotics and hope for response.
Remember that even paracetamol can decrease platelets so it is better to try to take as few as possible

As you probably know it takes several cycles before Dacogen is working. It is common that patients need supportive therapy with blood and platelet txs when they get Dacogen or Vidaza.
Since the fever can depends on an infection I think it is better to wait with Dacogen until your father is free from fever.
Kind regards
