No, there is not. Your PEP would have had no effect. EWH
Thank you for your response doctore. I'm sorry, i didn't quite understand the response. Is there any chance of a false negative for the exposure of 6 months ago because of beginning a PEP 2 days prior to the test?
Welcome to our Forum. The risk of getting HIV from oral sex, in the unlikely situation that your partner was HIV infected is very, very low. Here is a copy of a comment regarding oral sex and HIV that I have made to another person on the Forum- "The quoted figure for HIV risk, if one has oral sex with an infected partner is less than 1 in 10,000 and, in my estimation that is too high. Some experts state there is no risk at all from oral sex. Neither of us on this site have ever seen or reading the medical literature of a convincing instance in which HIV was passed by oral sex. "
If you were my patient, I would not have given you PEP following oral sex and may not have given it to you following heterosexual genital sex with a partner of unknown status that is not your question and I acknowledge that you don’t mention why you may have needed PEP). I am not trying to "shoot the messenger" here but PEP is expensive and the medications have a number of side effects. For doctors to just give PEP without making a commitment or arrangements for follow-up is, in my estimation, unprofessional.
Getting back to your question however, recent PEP would have had no effect on your risk for seroconversion from the earlier exposure, had it been risky. I hope this is helpful information for you. EWH
