The drug Tamiflu, given to tens of thousands of people during the swine flu pandemic, does nothing to halt the spread of influenza and the [UK] Government wasted nearly 500 million stockpiling it, a major study has found. The review, authored by Oxford University, claims that Roche, the drugs Swiss manufacturer, gave a false impression of its effectiveness and accuses the company of sloppy science. The study found that Tamiflu, which was given to 240,000 people in the UK at a rate of 1,000 a week, has been linked to suicides of children in Japan and suggested that, far from easing flu symptoms, it could actually worsen them. Roche claimed at the time of the 2009 swine flu outbreak that trials had shown that it would reduce hospital admissions and complications such as pneumonia, bronchitis or sinusitis. Based on [these claims], the Department of Health bought around 40 million doses of Tamiflu at a cost of 424 million and prescribed it to around 240,000 people. In 2009, 0.5 per cent of the entire NHS budget was spent on the drug. However, researchers from The Cochrane Collaboration, a not-for-profit organisation which carries out reviews of health data, found that Tamiflu only cut flu-like symptoms from seven days to 6.3 days and there was no evidence of a reduction in hospital admissions. Eight children who took the drug in Japan ended up committing suicide after suffering psychotic episodes. Other side effects included kidney problems, nausea, vomiting and headaches. Many people reported feeling anxious or depressed when taking the drug.
