Doxycycline Use in Animals

Doxycycline is a tetracycline antibiotic used to treat bacterial infections in humans and animals. It works by inhibiting the synthesis of protein within bacteria, thus causing the death of the organism. For animal use, it can be obtained only by prescription from a veterinarian.

Examples of bacterial infections in animals which can be combated with the use of this drug are urinary tract and respiratory infections, and any blood-borne infections. This might include those that occur as the result of a wound. Doxycycline is especially useful against tick-borne diseases such as Rocky Mountain spotted fever.

Side Effects

As with all drugs, Doxycycline should not be given to animals with a history of allergy to antibiotics. It may also interact with other drugs. If a pet is on any other medication, a veterinarian should be consulted. Antacids are known to interact with this drug. Diarrhea and vomiting have been observed, as well as discoloration of the teeth.

Dosing Information

Doxycycline is available in three forms -- tablets, oral liquid suspension and an injectable solution. Syringes made for pet use are available at pet supply stores. It should be taken every 12 hours, but not with any medications containing calcium. Calcium may prevent absorption of the antibiotic.

This antibiotic is not effective against viral or fungal infections. A pet owner who suspects that their animal may have an infection should have the pet diagnosed by a veterinarian to determine whether this product is right for them.
