Syphillis false negative due to antibiotics?
Hi,
I had my doctor pre-emptively treat me after an episode of unprotected vaginal sex for STDs with IM shot of rocephin and PO Zithromax. This was one week after exposure and tests for NGU and chlamydia did come back negative. Almost 8 weeks after the exposure I had a syphillis test and it was negative. I never had any symptoms of primary or secondary syphillis, but now my husband has a weird rash and my googling for answers has led to all kinds of scary things. Do you think the antibiotics would have caused false negative? Could I have never had symptoms and still have it? I tested negative for HIV with duo at 8, 10 weeks and Oraquick at home swab at 6, 6 1/2, 18 months. Trying to move past a bad decision and not attribute every health problem that pops up to this.

Thank you! That and the fact that I never developed a rash or any other symptoms should help ease my mind!
Syphilis is rare in straight men and in devloped countries. I would not be cocnerned with syphilis. The fact you have a negative test is good and if anything the medication you took could have cured syphilis but doubt you even had it to begin with.
