The US Food and Drug administration decided yesterday to approve the new female Viagra with a risk management program. The benefits of the drug, called fibanserin, are marginal; women having sex two to three times a month had sex one more time per month on average while on the drug. Meanwhile, side effects include sudden drops in blood pressure and the risk of fainting at unpredictable times. The FDA recommends that the drug require doctors to have specific licenses to prescribe it, and warn against the use of alcohol while taking the drug, among other precautions.

The libido-enhancing drug doesn't work like Viagra though. Women take fibanserin every day regardless of whether or not they want sex. Originally developed as an antidepressant (it didn't work), the pill works by altering brain chemistry (rather than increasing blood flow to the genitals, like in the case of male Viagra.)
