It started off as a deep painful, cough and then a 2 days fever which I kicked through home remedies. Then returned after 3 days with fever ranging from 100-102 for the last 5 days. Started the Zpack and am dosing my fever with ibuprofen or Tylenol every 4 hours. At this point it's been almost 6 days of this and I don't know what else to do. Does the Zpack normally take this long?
