Cefovecin Antibiotic Injection for Dogs & Cats

Convenia is an injectable antibiotic. It treats infections caused by susceptible strains of Staphylococcus intermedius and Streptococcus canis in dogs and Pasteurella multocida in cats. Convenia pet medications typically require only one subcutaneous administration, which provides 14 days of effectiveness against bacterial infections.

Convenia treats susceptible skin infections, abscesses, and pyoderma in cats and dogs. Its potency allows for successful treatment usually with only a single administration. Convenia is generally well tolerated and is safe for young pets and adults. 

Benefits of Convenia:

  • Treats many of the most common skin infections
  • Useful for wounds, abscesses, and pyoderma
  • One use kills bacteria for 7 to 14 days, and typically provides full treatment
  • Easily administered via subcutaneous injection
  • Well tolerated by most pets
  • Safe for use in young cats and dogs

Convenia is only intended for use in cats and dogs. Do not administer to other species. Do not use in any animal for which it was not prescribed. Not for use in humans.

For subcutaneous injection only.

Follow the specifications of the prescription.

CAUTION: The susceptibility of the infection should be determined prior to use. Use with non-susceptible organisms will not provide benefit and increases the risk of antibiotic-resistant strains.

If no improvement is seen within 3 to 4 days, contact your veterinarian for reconsideration of the diagnosis and treatment plan.

Do not exceed one dose in cats and two doses in dogs.

Not for use in animals with an allergy to cefovecin, other cephalosporins, or penicillins. Anaphylaxis may occur and requires emergency veterinary treatment, possibly including epinephrine, oxygen, corticosteroids, intravenous fluids or antihistamines, airway management, or other therapies.

Consult your physician or a poison control center in the event of human exposure. Convenia may trigger allergic reactions in susceptible human individuals during handling. Such individuals should avoid contact with the skin and mucous membranes.

The safety of Convenia in animals younger than 4 months of age and in lactating and breeding animals has not been proven.

The long-term effects at the site of injection have not been determined.

It takes up to 65 days for 97% of this medication to be eliminated from the system. Animals experiencing adverse effects should be monitored for the duration of this period.

Side effects may include irritation at the site of injection, diarrhea, emesis, diminished appetite, and lethargy. Additional side effects in dogs may include bloody stool, flatulence, increased rumbling in the stomach, and dehydration. Additional side effects in cats may include inappropriate urination, hyperactivity, and strange behavior. Consult your veterinarian about any adverse reactions that are particularly bothersome to your pet.

Convenia may interact with NSAIDs, anticonvulsants, propofol, cardiac medications, behavioral medications, and other drugs and supplements. Consult your veterinarian before concurrently administering any other drugs or supplements.

Positive direct Coombs' test results, false positive reactions for glucose in the urine, and falsely elevated urine protein determinations have occurred with use of some cephalosporins. These and other antimicrobials may also cause lowered albumen values.

Cephalosporins have been associated with myelotoxicity, causing a toxic neutropenia. Other hematological reactions may include anemia, neutropenia, hypoprothrombinemia, thrombocytopenia, prolonged prothrombin time and partial thromboplastin time, platelet dysfunction and temporary increases in serum aminotransferases.

Use or discard the contents of the vial within 28 days of reconstitution.
