After accessing the full data on Roche's flu medicine Tamiflu, researchers raised concerns regarding the effectiveness of the medicine in a recent review and said governments who stockpile it are wasting billions of dollars.
The antiviral drug Tamiflu helped in reducing the risk of death by around 25 percent among adults who were hospitalized during 2009 H1N1 swine flu pandemic, a new report has claimed.
Genentech, which is a part of Roche, has announced that its liquid Tamiflu for children is currently in short supply.
New research showed there are no added health advantages to taking a double dose Tamiflu (Oseltamivir) when dealing with the flu, even though several doctors prescribe a double dose for patients who have more severe cases.
Doctors report that three patients infected with the bird flu, H7N9 are resistant to Tamiflu, an antiviral drug used to treat the virus.
