Can you take atripla and azt (zidovudine) at the same time?

Yes, but...: You can, though it's an unusual combination. Azt (zidovudine) is no longer widely used in the U.S. Because of toxicity. Atripla alone is effective treatment against HIV infection in someone without drug resistance. The combination of azt (zidovudine) and Atripla could be used in someone with a modest degree of resistance to the nucleoside analog class of antiretrovirals, but it wouldn't be my first choice.
