Any medication can cause nausea and vomiting in individual patients and both urinax and antibiotics could be contributing. If the discomfort and straining has resolved you should discuss withdrawing the urimax with your vet. It would be useful to know how long she has been on the antibiotics - I would recommend a repeat urine sample if longer than 5-7days to see if the condition has cleared and it may be possible to withdraw the medication to see if this resolves the vomiting. If so, a repeat sample after 7-10days would be recommended to check for any relapse given the short treatment time.
