Isentress general information

What is Isentress used for?

Isentress tablets 400mg are used to treat Human Immunodeficiency Virus (HIV) infection, in combination with other HIV medications.  This combination therapy is known as highly active antiretroviral therapy (HAART).  HIV impairs the immune system by attacking specific immune cells called CD4+ cells that are involved in fighting infection, which can lead to opportunistic life-threatening infection (infections that would not normally be harmful).  If too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS).  Isentress tablets 400mg help prevent or slow down the ability of HIV to replicate, which reduces the viral load by keeping the amount virus down to a low level and this results in an increase in CD4 cell numbers, so that the immune system can recover reducing the risk of disease progression.
