The Indiana Attorney General’s Office is warning against shampoos, air filters and face masks that claim to prevent contraction of the H1N1 flu virus.Spokesperson Bryan Corbin says the FDA released a warning recently that a number of retailers are producing such products and that they are not FDA-approved and are ineffective.He says some online pharmacies are selling fraudulent flu treatments.“Some of these places have been selling what they call generic Tamiflu," says Corbin. "Well, for one, there is not a generic version of Tamiflu available on the market, and then when these things have been chemically analyzed according to the FDA, it turns out to be Tylenol crushed up with talcum powder, it’s a totally fraudulent drug.”Corbin says they’ve received no complaints from people in Indiana regarding such products, but wanted to alert Hoosiers of the scams.
