Thank you for getting in touch with us. From what I make out, your friend underwent an ELISA
test 2 years ago and it came positive. It would have been better if your friend had undergone the Western Blot test before starting with treatment. Western Blot is the confirmatory test for HIV
and treatment is started only after it is positive. It would have been better if you had told us if he took any medicines for HIV. The medicines you have mentioned here are not for HIV and are of different classes. I would recommend your friend to get in touch with an Internal Medicine specialist and undergo Elisa and Western Blot once again. If the results are positive, he can start with antiretroviral medicines. If it is negative, which is quite possible, then he can start his life all over again. Hope this helps.
