What Viramune XR is used for
Viramune XR is used in the treatment of the infection caused by the Human Immunodeficiency Virus (HIV-1). HIV-1 is the main
virus responsible for the development of Acquired Immunodeficiency Syndrome (AIDS).
Viramune XR contains the active ingredient Nevirapine. Nevirapine belongs to a group of antiretroviral medicines called non-nucleoside
reverse transcriptase inhibitors (NNRTIs). It works by inhibiting or interrupting the enzyme reverse transcriptase that the
HIV virus needs to multiply.
Viramune XR does not cure or prevent HIV-1 infection or AIDS, but it does hinder the growth of HIV-1.
Viramune XR is prescribed in combination with other antiretroviral medicines which hinder the growth of HIV-1 in other ways.
When these medicines are taken with Viramune XR, the growth of HIV-1 is hindered more effectively.
Viramune XR has not been shown to reduce the likelihood that you will develop the illnesses associated with advanced HIV-1
infection. It is important for you to continue seeing your doctor regularly.
Viramune XR does not reduce or prevent transmission of HIV-1 to others through sexual contact or blood contamination.
