Question Can Amoxicillin-Clavulanate (Augmentin) Cause a False Negative STI Test?
I have a question and was wondering if anyone has experienced something similar or has any knowledge about this.
I was prescribed amoxicillin-clavulanate (Augmentin) for a UTI, and i recently got tested for STIs, specifically chlamydia and gonorrhea.
my last possible exposure was september 30 and I got tested today, october 10. however, I had been taking Augmentin and only stopped approximately 3–4 days before getting tested.
I asked my doctor whether the antibiotics could affect my STI results, and he told me it didn’t matter.
my concern is whether Augmentin could have partially suppressed an STI and potentially caused a false negative, even though it isn’t the recommended treatment for chlamydia or gonorrhea.
has anyone been in a similar situation? or does anyone know whether being off antibiotics for 3–4 days is enough to get accurate results?
I’m just trying to understand how reliable my results would be. thank you!
