How does Lexiva work?
Lexiva works by blocking a specific HIV enzyme that prevents HIV replication. When Lexiva is taken in combination with other HIV medications the goal is to prevent the virus from further weakening the immune system. If Lexiva is effective expect to see an increase in T-cells (CD4 T-lymphocytes) and decrease in HIV viral load.

Does Lexiva need to be taken every day?
Not everyone will respond to Lexiva, however you can improve your chances Lexiva will work by taking ALL your medications everyday. Taking all your medications on schedule everyday is the best way to keep the HIV virus under control. Missing doses gives the virus a chance to develop resistance and a resistant virus can be difficult to treat.

How should Lexiva be taken?
