What is HIV Medication Resistance?

Every person who lives with HIV faces the risk of developing medication resistance. Resistance means that your treatment can fail as the virus changes and grows. This may cause your CD4+ cell count to go down and your viral load to eventually go up. Medication resistance may also limit your future treatment options. Your healthcare provider will monitor your numbers, and will order a blood test to check for resistance if he or she has any concerns.

One way you may develop resistance is by not staying 100% adherent to your treatment regimen.

If you have concerns about resistance, talk to your healthcare provider about why a medication with a high genetic barrier to resistance might be right for you.
