Reyataz

Generic name: atazanavir sulfate

What is Reyataz?

Reyataz is a prescription HIV-1 (Human Immunodeficiency Virus-type 1) medicine that is used with other antiretroviral medicines to treat HIV-1 infection in adults and children 3 months of age and older and who weigh at least 11 pounds (5 kg). HIV-1 is the virus that causes AIDS (Acquired Immunodeficiency Syndrome).

Reyataz should not be used in children younger than 3 months of age.

When used with other antiretroviral medicines to treat HIV-1 infection, Reyataz may help:

  • reduce the amount of HIV-1 in your blood. This is called “viral load”.
  • increase the number of CD4+ (T) cells in your blood that help fight off other infections.

Reducing the amount of HIV-1 and increasing the CD4+ (T) cells in your blood may help improve your immune system. This may reduce your risk of death or getting infections that can happen when your immune system is weak (opportunistic infections).

Reyataz does not cure HIV-1 infection or AIDS. You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses.
