PEP for someone already with HIV to prevent superinfection
Oct 2, 2009
Hi doctor, I'm am on Atripla for the last 7 months with undetectable viral load. Last night I was having sex with a man with unknown status, he was the insertive partner and the condom broke-during anal sex. I told him about my status and he should probably seek PEP, he didn't seem to panic and now I can't stop thinking that he also had HIV (although he said he did not) and passed me a resistant strain. Does it make sense to add more medications to my regimen to prevent transmission of a resistant strain? It's possible that he had a virus resistant to one or more components of atripla, I am extremely worried. Should I run to an emergency room?

Hello and thanks for your interesting question.
In brief, in my opinion, the answer is no. I'd have to think that given that the risk of superinfection appears to be pretty low AND that your liaison has an unknown (rather than known drug-resistant, HIV+) status, that the additional benefit of adding more medications to your Atripla is low.
It's not unreasonable to go to your primary healthcare provider (hopefully it's not an emergency room, if your receiving Atripla) and let them know of your exposure. My worry for you isn't getting drug-resistant HIV superinfection, but rather hepatitis, syphilis, gonorrhea or chlamydia.
Be well and best of health to you, BY
