Q and A


I have started PEP and want to know if I will be okay?

I had sex with a transexual man. I was on top and without me realizing the condom had ruptured, I washed myself and went home. But I did not feel comfortable. So I sent a text asking the man I had just had sex with if he was HIV positive, to which he answered, yes. I freaked out and went inmediately to the internet and did some research. I read about PEP, so the next morning I went to the clinic and I was placed on – Truvada 200 mg, Norvir 100 mg and Reyataz 300 mg. This was 36 hours after the incident.

I have had no side effects. But for the last two days, I have felt as if I have some fever. I tested my temperature and it is within the normal parameters of 98.2 and 98.7. Please tell me do I have a shot to be well? The person I had sex with told me that his viral count is below 40. Please help.


Thank you for your question.

I am sorry to know that you are distressed. What is important is that you have taken the right steps to giving yourself a chance of remaining  uninfected. PEP is effective the earlier that you take it and should be taken within 72 hours of being exposed to HIV. You started PEP within that time frame.

Additionally, as the person who you had sex with is on treatment with an undetectable viral load, then your chances of an HIV infection are much more reduced than if that person was not on treatment.

If you take the PEP as prescribed this will reduce the small chance that you were exposed to HIV.

Symptoms do not occur this soon after an exposure.

Good luck.

    Hi Faith,

    If you have been exposed to HIV then it’s a good idea to take PEP.

    However, if your man is taking HIV meds (called ART) and has an undetectable viral load, then HIV can not be transmitted. And that’s even if you don’t use condoms. Please see more info at this link to Undetectable = Untransmittable.

    Hi Fikile,

    Tenemine is a generic form of Truvada. Truvada used on its own is called PrEP. PrEP is used to prevent HIV infection.

    Tenemine can be used with other HIV drugs as treatment (called ART) for someone who is HIV positive. If you have been taking ART and have an undetectable viral load you can not transmit HIV even if you don’t use condoms. Please see U=U here.

    Hi Emza,

    It’s good that you went to the doctor before 72 hours. The sooner you start PEP the better.

    And now that you’ve finished PEP you need to wait 28 days to have another test to check that it’s worked.

    For more info about PEP please see this link.
