I'd like to avoid resistance testing, if possible. I'm in Brazil and it is very expensive here. Please, reply to this. I am very worried. Assuming your are taking all your meds correctly and at the appropriate doses, there may be a problem.
Resistance is possible.
It gets a little tricky after that. This is where resistance testing would be helpful. Likewise with nelfinavir, depending on which mutations, if any are present, determines whether you go to another protease inhibitor, or use a different class drug like sustiva. I think in any case a change is in order. Experts appearing on this page are independent and are solely responsible for editing and fact-checking their material.
