Even if efforts to develop a vaccine are successful New Scientist, 26 March, p 1, it could take many months to produce the billions of doses needed in the event of a pandemic. At that meeting, FDA staff described reports of about 700 cases of psychiatric adverse events for both drugs and 25 cases of pediatric deaths in patients taking Tamiflu, reported to the agency through May 2007, No fatalities were reported for Relenza. 75mg tamiflu oken said he and his four partners at Charter Internal Medicine are each getting one or two calls a week from patients seeking the medicine. The changes to the label reflect observations from a growing body of data, which shows no evidence of a causal relationship between Tamiflu and the reported adverse events, Roche said in a statement. Taken over 75mg tamiflu a long time, benzodiazepines clearly create more problems than they solve. The run on Tamiflu was apparently spurred by government warnings, here and abroad, that chances for 75mg tamiflu a worldwide flu epidemic are rising, and by news that Southeast Asias H5N1 bird flu – the leading candidate for a pandemic – is moving westward. Swedish scientists say that Tamiflu – the frontline weapon in any bird-flu pandemic – cannot be broken down by sewage systems and this could help the virus mutate dangerously into a drug-resistant strain. The mutated H1N1 75mg tamiflu is a sub-type of influenza A. Tamiflu can save lives if it is given early, no more than two days after symptoms first appear. If each infected person passes the virus to fewer than two other people on average, then isolating and treating all cases and their contacts with antivirals could slow or even stop an epidemic, he calculates. It did not change its recommendation that Tamiflu be used to treat human cases of bird flu. Tamiflu is also used to reduce the chance of getting the flu in people aged 13 and older who have a higher chance of getting the flu because theyve been spending time with someone who has been inflicted with 75mg tamiflu the flu. Neither Japan – where Tamiflu is widely prescribed for seasonal flu – nor Hong Kong had seen increased resistance to date, it said. In the case of the first teenage death, Hurley said the boy had taken Tamiflu after first being treated with amantadine, an older anti-flu drug that is well-known for central nervous system 75mg tamiflu side effects. The St Louis-based company, whose clients include 16,000 private employers, labor unions, HMOs and government agencies, typically sees prescriptions for the drug rise in early fall. Terence J Hurley, a spokesman for Roche, the giant Swiss pharmaceutical house that makes Tamiflu, confirmed that prescriptions are up considerably compared to 75mg tamiflu last year at this time. 75mg tamiflu adverse events reported on the Japanese label include impaired consciousness, abnormal behaviors, hallucination and other psychological and neurological symptoms, Hurley said. In Japan, which uses Tamiflu for ordinary flu epidemics, the mutation appears in 16 per cent of treated children, yet such viruses almost never go on to infect others. It has become less lethal and is occurring in larger clusters than 75mg tamiflu past cases. The proposed mechanism of action of oseltamivir is inhibition of influenza virus neuraminidase with the possibility of alteration of virus particle aggregation and release. Roche is the only maker of Tamiflu, which takes more than six months to synthesize in a complicated and dangerous manufacturing process.
