Norvir is for adults who are infected with the human immunodeficiency virus (HIV), the virus which causes AIDS. Norvir is prescribed for use in combination with other antiretroviral medicines.

Norvir is not a cure for HIV infection or AIDS. People taking Norvir may still develop infections or other serious illnesses associated with HIV disease and AIDS. It is important that you take Norvir every day exactly as your doctor prescribed it. Even if you feel better, do not stop taking Norvir without talking to your doctor.
