bottle of compounded doxycylcine suspension for cats

Doxycycline is an antibiotic commonly prescribed by veterinarians for cats with a variety of illnesses.

One of doxycylcine’s most frequent uses is for “kitty colds” or upper respiratory infections because it is effective against a broad spectrum of bacteria. Generally doxycycline is well tolerated with minimal side effects in cats.

What is Doxycycline?

Doxycycline is an antibiotic in the class called tetracyclines. These antibiotics are bacteriostatic. That means they prevent bacteria from reproducing but do not kill the bacteria outright. Stopping the bacteria from reproducing, and therefore the infection from worsening, gives the body’s immune system the opportunity to kill the bacteria and cure the infection. Tetracycline antibiotics are effective against a broad spectrum of bacteria types making them very useful in veterinary medicine.

Doxycycline comes in several formulations which are used interchangeably in veterinary medicine. It is readily available from your regular veterinarian or a local pharmacy as it is commonly used in human medicine as well.

Doxycycline is not FDA approved for use in cats in the United States, therefore its use is considered “off-label” or “extra-label.” Many medications commonly used in veterinary medicine fall into this category. This does not mean it is less safe or less effective. Any medication used off-label should be under the close guidance of your veterinarian.
