Also, please read this leaflet each time you renew the prescription, just in case anything has changed. This is a summary and not a replacement for a careful discussion with your doctor.

Alert: Find out about medicines that should NOT be taken with VIRACEPT. Please also read the section “MEDICINES YOU SHOULD NOT TAKE WITH VIRACEPT”. WHAT IS VIRACEPT AND HOW DOES IT WORK? VIRACEPT is used in combination with other antiretroviral drugs in the treatment of people with human immunodeficiency virus (HIV) infection. Infection with HN leads to the desbuclion of CD4 T cells, which are important to the immune system.After a large number of CD4 cells have been destroyed, the infected person develops acquired immune deficiency syndrome (AIDS). VIRACEPT works by blocking HIV protease (a protein-cutting enzyme), which is required for HN to multiply. VIRACEPT has been shown to significantly reduce the amount of HIV in the blood. Although VIRACEPT is not a cure for HN or AIDS, VIRACEPT can help reduce your risk for death and illness associated with HIV. Patients who took VIRACEPT also had significant increases in the number of CD4 cell count. VIRACET should be taken together with other antireboviral dnrgs such as Retrovirf’ (zidovudine, AZI), Epivir" (lamivudine, 3TC), or Zerit° (stavudine, d41). Taking VIRACEPT in combination with other antiretroviral drugs reduces the amount of HN in the body (viral load) and raises CD4 counts. VIRACEPT may be taken by adults, adolescents, and children 2 years of age or older. Studies in infants younger titan 2 years of age are now taking place. DOES VIRACEPT OURE HW OR AIDS? VIRACEPT is not a cure for HN infection orAlDS. People taking VIRACEPT may still develop opportunistic infections or other conditions associated with HN infection. Some of these conditions are pneumonia, herpes virus infections, Mycobacterium avium complex (MAC) infections, and Kaposi's sarcoma. There is no proof that VIRACEPT can reduce the risk of transmitting HN to others through sexual contact or blood contamination. WHOSHOULDORSHOULD NOTTAKEVIRACEPT?
