It was not tamiflu. At the time of seeing the doctors my only symptom was complete lack of taste. The doctor referred me to an ENT where all sorts silly tests with ice cream like sticks were conducted. The coughing (a dry and sore cough) developed later and put me flat on my arse for about week. I didn't take any medication for the flu like symptoms.His Dr probably gave him tamiflu if it was done as an out patient. Wont work but no harm in trying.
