I started herxing 3 days after I started the doxycycline, and pretty much herxed for weeks. It didnt stop until I plataued, and then my Dr added zithromax, and i started herxing again, but mildly and less often. Then she switched me from doxy to bactrim, and i herxed a few times and now very rarely. are you herxing at all?
