HIV NRTI / NNRTI combinations are used to treat and manage HIV-1 infection. These medications work by blocking the virus's ability to make copies of itself in your body, which helps to prevent the spread of the infection and to improve your immune system. They come in oral form, making them easy to take. Examples include Atripla, Symfi, and Odefsey. Work with your HIV specialist to decide which medication best fits your treatment plan.
