March 3, 2009 --The first female sex patch received a lot of publicity after it was approved for use in Europe. But now a top medical journal is casting doubt that it works. A review of the drug Intrinsa finds the testosterone patches do not appear to do much to boost a woman's sex drive after menopause and the long term safety is still unclear. That's according to the Drug and Therapeutics Bulletin, which found the published evidence so far is based on highly selected women and only shows small improvements.
Intrinsa was not approved in the US. Regulators say there was a lack of evidence for long term safety.
