Please consider attempting to clarify which infectious agent(s) you're dealing with. This is done best by PCR testing which is pricey but very specific and sensitive. I'm primarily interested in the feline herpesvirus (FHV-1) which is most common but doesn't respond to antibiotics; instead, an antiviral drug such as famciclovir should be considered; Chlamydophila and Mycoplasma - both of which are best addressed with doxycycline. Care has to be taken when receiving a positive FHV-1 diagnosis by PCR because prior vaccination will confound the diagnosis. If no other infectious agents are identified, however, active FHV-1 should be assumed to be present.
Please respond with further questions or concerns if you wish.
Hello, this is Dr. Jess. Just clarifying, is your question whether or not more azithromycin may be indicated? How long of a course of this did your kitty take before?
Ok, just making sure.
