How to get rid of flue quickly?

Flu: If diagnosed early by your doctor within the first 2-3 days, then a prescription antiviral medication can help. Otherwise, it's just lots of sleep, warm fluids, ibuprofen, tylenol (acetaminophen) and more sleep. The fever and chills go away after a few days, but the cough and sore throat could last 1-2 weeks afterwards. If fevers go, then come back again, that's cause for concern and you should see your doc!
