My vet prescribed Doxylin/Doryx/Vibravet or Doxycycline for my cat.  What does that mean?

Doxycycline is an antibiotic drug, used to treat a variety of illnesses in cats.  It is sold in Australia under the brand names Apex Doxy,  Doxylin, Doryx and Vibravet, as well as under the drug name Doxycycline.   The different brands offer the same active ingredient in different strengths and different delivery methods (tablet, suspension, paste, etc) and you should check with your vet if you intend to change between the brands.. 

Doxylin is often used by vets to treat cats with upper respiratory infections, sometimes called “kitty colds”, because Doxylin treats a broad spectrum of bacteria.  It can also be used to treat infections of the mouth (including periodontal disease) and urinary tract infections.  Doxycycline can also be used in the treatment of heartworm in cats - it attacks a bacteria found inside heartworms, weakening the heartworm.
