Reyataz is a prescription medicine used with other anti-HIV medicines to treat people who are infected with the human immunodeficiency virus (HIV). Reyataz is a type of anti-HIV medicine called a protease inhibitor. Reyataz helps to block HIV protease, an enzyme that is needed for the HIV virus to multiply. Reyataz may lower the amount of HIV in your blood, help your body keep its supply of CD4 (T) cells, and reduce the risk of death and illness associated with HIV.

Reyataz does not cure HIV infection or AIDS. People taking Reyataz may still get opportunistic infections or other conditions that happen with HIV infection. It is very important that you see your healthcare provider regularly while taking Reyataz.

Even if you are taking Reyataz, you may still pass HIV to other people through sexual contact, sharing needles, or being exposed to your blood. For your health and the health of others, it is important to always practice safer sex and never use or share dirty needles.
