Lamivudine 300 mg VS Emtricitabine 200 mg

Question

Dear Doc,

Hope this email finds you well. I really need your advise. My viral load is undetectable now with CD4 500 plus. But if from time to time I switch my meds : Efavirenz+Lamivudine+Tenofovir disoproxil fumarate with TEEVIR (Efavirenz+Emtricitabine+Tenofovir disoproxil fumarate) would that be a problem??

I heard both are atripla, yet sometimes the meds are not available, so I switch between those two options. Would there be any side effect? Or do you recommend just stick to only one type of meds?

B/rgds, Alloysius

Answer

In most cases persons can switch between those fairly comparable regimens (main difference is between the emtricitabine and lamivudine) with minimal side effect difference or change in viral control. KH
