I had been tested positive for syphilis with VDRL titre 1:16 reactive and 1:32 minimal reactive. I received 2 penicillin injections with gap of 21 days . But the titre has settled at 1:8 and is not moving down even after taking pentids 400 tablets continuously for 40 days after second injection. The treatment period has now reached to 60 days.How should I proceed with my treatment? And how long would it take to treat this stage of syphilis.
Although those are not recommended regimens for treatment of syphilis, the VDRL titer can remain positive for months to years after successful treatment.
