Doxy only cures chlamydia if I am correct. I got treated for both chlamydia and gonorrhea just in case when I thought I wasn't cured and it was two different medications.
may be from a yeast infection due to the doxy you were taking for acne. What Vance didn't say was that we do not advise on self medicating so, if that is why you are asking, it is strictly unadvised.
Even though you were taking doxy, it doesn't mean you were taking the correct dosage to cure chlamydia if you had it.
