Truvada is a branded PrEP HIV medication version of the generic PrEP HIV medicine, Emtricitabine / Tenofovir disoproxil fumarate (manufactured by Gilead Sciences Inc), that is commonly used for HIV prevention. PrEP stands for pre-exposure prophylaxis. It is the only pre exposure prophylaxis treatment recommended by the Centers for Disease Control and Prevention (CDC)Truvada HIV PrEP tablets can also be used alongside other HIV medications to help control and prevent HIV infections. It helps to decrease the amount of HIV in your body, allowing your immune system to work better. Emtricitabine/Tenofovir (generic Truvada) also lowers the chance of getting HIV-based complications and helps with improving the quality of life of people with HIV. If you believe you may be HIV positive, it is recommended to take a HIV test as HIV testing is the only way to accurately determine your HIV status. Alongside Emtricitabine, Truvada contains the original form of tenofovir as tenofovir disoproxil fumarate (TDF). This is the key difference compared to the alternative HIV-1 infection PrEP treatment, Descovy (Tafero EM), which contains a newer form of tenofovir called tenofovir alafenamide (TAF).
