Recently I found out that there are meds with help of which you can treat and prevent HIV. Did you hear about it? Meds is called Truvada. Tenofovir/emtricitabine (Truvada) is a fixed-dose combination of two antiretroviral drugs used for the treatment of HIV/AIDS. It was developed by Gilead Sciences and consists of 300 milligrams of tenofovir disoproxil fumarate (of which 245 mg is tenofovir) and 200 milligrams of emtricitabine.
