My cat was diagnosed with feline herpes virus by a veterinary ophthamolgist after a month of worsening eye symptoms. My regular vet wasn't sure what was going on. The opthamologist prescribed oral famciclovir for two weeks and lysine gel. Has anyone had experience with treating herpes keratitis with famciclovir? It doesn't appear to be very effective in the studies I have read. I am hoping someone has had some experience with it.
