[Question #287] std ps

35 months ago
Dear Doctors, about 4 months ago I had casual vaginal sex with a female sex worker, a condom was used.  Since then I have had a lot of anxiety and I was prescribed Melex and Paxil, both are anti anxiety drugs.  I was tested for HIV (4th generation Duo test) and also VDRL, at 8 weeks and then at 12 weeks, all came back negative.  Do the anti anxiety drugs Im taking could have affected the test results, are there any other tests I should be considering protected sex?  Thank for your support and help.

Sorry, I will like to correct my question, probably is not clear.  Dear Doctors, about 4 months ago I had casual vaginal sex with a female sex worker, a condom was used.  Since then I have had a lot of anxiety and I was prescribed Melex and Paxil, both are anti anxiety drugs, also I am taking regularly Attacand for high blood pressure.  I was tested for HIV (4th generation Duo test) and also VDRL, at 8 weeks and then at 12 weeks, all came back negative.  Do these  drugs Im taking could have affected the test results, are there any other tests I should be taking considering the risk I had having protected sex?  Thank for your support and help.

Welcome back to the forum. But it is distressing to see you remain so concerned about an exposure that carried no significant risk of infeciton.

There are no drugs or medications that have any effect on the reliability of tests for HIV, syphilis, or any other STD. That includes all the drugs you mention. Dr. Hook already answered your concerns about syphilis. Your negative HIV duo test also is conclusive.

I do not recommend any other STD tests on account of this exposure.

I hope these comments help you to move on without worry. Best wishes and stay safe--  HHH, MD

To clarify, there are no drugs at all that have any effect on HIV. Some antibiotics of course can interfere with testing for syphilis or other bacterial STDs. But no worries about the drugs you have taken recently.

dear Doctor, just to be sure, are both these tests 100% conclusive at the 84th day or 12 weeks, thank you.

Yes. The duo HIV test is 100% conclusive at any and all times 4 weeks or more after the last exposure.

thank you, what about the vdrl?, is it also conclusive (100%) at 12 weeks?

Yes. VDRL is conclusive any time 6 weeks or more after exposure, and forever after that (as discussed with Dr. Hook a couple of weeks ago).

That completes the permitted two follow-up questions and replies, and so ends this thread. Hopefully you won't need to ask anything more about the exposure a few months ago. It is clear you acquired no STD and need not give it another thought. Best wishes and stay safe.
