What Is Resistance?

Resistance means HIV has mutated, or changed, so that medicines no longer work the way they should. Resistance can occur with HIV medicines, including INTELENCE® (etravirine).

Over time, resistance can lead to a higher viral load and fewer CD4+ cells. When medicine can no longer fight resistance, it is called treatment failure. The best way to handle treatment failure is to change medicines. However, you should not change or stop taking your medicine without talking to your healthcare professional first.

Resistance is one more reason why medicine must be taken as prescribed

Once HIV becomes resistant, there may be fewer treatment options to turn to. This is why it is so important to stick with the prescribed treatment plan and to tell your healthcare professional if there are any problems in taking HIV medicines.

Talk to your healthcare professional to learn more about resistance.
