A leading British medical journal is asking the drug maker Roche to release all its data on Tamiflu, claiming there is no evidence the drug can actually stop the flu.
The drug has been stockpiled by dozens of governments worldwide in case of a global flu outbreak and was widely used during the 2009 swine flu pandemic.
Today, one of the researchers linked to the BMJ called for European governments to sue Roche.
"I suggest we boycott Roche's products until they publish missing Tamiflu data," wrote Peter Gotzsche, leader of the Nordic Cochrane Centre in Copenhagen. He said governments should take legal action against Roche to get the money back that was "needlessly" spent on stockpiling Tamiflu.
Last year, Tamiflu was included in a list of "essential medicines" by the World Health Organisation, which often prompts governments or donor agencies to buy the drug.
WHO spokesman Gregory Hartl said the agency recommended the drug be used to treat unusual influenza viruses like bird flu. "We do have substantive evidence it can stop or hinder progression to severe disease like pneumonia," he said.
In 2009, the BMJ and researchers at the Nordic Cochrane Centre asked Roche to make all its Tamiflu data available. At the time, Cochrane Centre scientists were commissioned by Britain to evaluate flu drugs. They found no proof that Tamiflu reduced the number of complications in people with influenza.
