Question: how long does the flu last with tamiflu?
Answer: Or at least shorten the time we spend in bed with it. So the antiviral drug oseltamivir (Tamiflu®), which helps your body bounce back faster from flu, holds a lot of appeal. Researchers find that taking oseltamivir within 48 hours of symptom onset can shave approximately one day from a typical seven-to-10-day illness.
