Must you take oseltamivir if you have contracted H1N1 influenza?

It is not necessary to take oseltamivir. Influenza A virus is usually caused by infection with the influenza virus. Oseltamivir is a neuraminidase inhibitor and an effective antiviral medication for treating both influenza A and B. If symptoms are mild, oseltamivir may not need to be taken. However, if symptoms are severe, treatment with medication should be carried out according to individual circumstances and under the guidance of a physician.
