Sometimes it takes a couple rounds of meds to completely clear up an RI. Also a lot of times if the RI keeps coming back, it is most likely related to husbandry somehow. You can take her back into the vet and have another culture done(im assuming you had a culture done in the first place to determine the exact bacteria it was and to make sure the Baytril was most effective on it). Took my beardie 2 rounds of Baytril to clear her up plus keeping her temps up and giving her heat at night as well. RIs can be a real pain to deal with.
