But Health Canada isn't so sure The Federal department, which monitors health product claims and performance, recently ordered Tambrands to remove the crescent moon on its packaging which heralds the safety of overnight use. Personally, I don't recommend overnight use at all. Liz Armstrong, co-author of the 1992 book, Whitewash, which explored the issue of chlorine content in menstural products and diapers, says tampon companies regularly downplay the possible health risks of TSS when marketing their products. There's an awful lot of nonsense in this kind of overnight recommendation. It's expedient for them to gloss over some of the problems associated with tampon use.
Any drug company tends to have their stable of doctors that substantiate that company's claims.
You take everything with a grain of salt. Tierno and his research partner Bruce Hanna are the only two independent tampon researchers in North America who aren't funded by tampon companies which retain the option of reviewing the research and may prevent researchers from publishing their findings in some cases. It's more than just playing politics with research - we're talking about life and death for tampon manufacturers here.
