Since this site has had HIV scares and HIV+ members in the past, I did want to bring people's attention to this drug I hadn't heard of before. Truvada is a pill you take daily which gives you some protection against getting infected with HIV.
It is still controversial, not because of its effectiveness or minimal side effects, but because it has the untrue stigma of encouraging risky behavior.

It is being stigmatized in a way that no one would think to do to someone taking birth control every day.
If you are younger and sexually active, you should know there are new measures to keep you even more healthy that are likely covered by your (or your parents's) insurance.
