Most Asked

  • What type of medication is CONVENIA® (cefovecin sodium)?

    CONVENIA is part of the group of antibiotics called cephalosporins. It is manufactured and distributed by Zoetis.

  • What infections or conditions does CONVENIA treat?

    CONVENIA treats common bacterial skin infections in dogs, including superficial pyoderma in dogs as well as abscesses and wounds for both cats and dogs. These conditions can cause itching, scratching, licking and biting.

  • How does scratching and biting make skin conditions so much worse?

    When your pet's skin is broken or damaged by scratching, chewing or rubbing, it creates an opportunity for additional or secondary infections, allowing bacteria that’s normally kept out to penetrate your pet’s skin.

  • How is CONVENIA different from most antibiotics approved for feline and canine bacterial skin infections?

    CONVENIA is unique in this category for two reasons: 1) It’s injectable, and 2) a single dose actively fights infections for a long time. In studies, a single injection of CONVENIA was found to be the equivalent of 14 days of orally dosed antibiotics* (e.g., tablets or pills, some of which have to be administered by pet owners as often as twice daily).

  • How does CONVENIA work?

    CONVENIA kills the bacterium by breaking down its cell wall. Within 30 minutes of being injected under the skin, detectable concentrations of CONVENIA are at the site of infection. Within four hours, on average, it reaches a high enough concentration to start killing bacteria.1 CONVENIA will continue killing bacteria in the infected tissue for the full treatment period — 14 days.*


  • What is the price per injection for CONVENIA?

    The cost will vary based on the size of your pet. Your veterinarian will be able to answer this for you.

  • Where can I buy CONVENIA? Is it available at pharmacies or pet supply stores?

    CONVENIA is a prescription-only product. It is an injection that must be administered by a veterinary professional.

Strength and Duration

  • What is the dosage of CONVENIA, or how is it dosed?

    CONVENIA is administered by your veterinarian as an injection under the skin. The dosage is based on your pet’s weight.

  • How long does it take CONVENIA to start working in a dog or cat?

    Every pet and every infection is different. Peak blood levels are seen within 2.0 hours in cats2 and 6.2 hours in dogs.1 This means that CONVENIA can start killing the bacteria quickly. However, this is not when you would expect to see a difference in the skin. Based on the severity of the infection, your veterinarian is best able to predict when a difference in the skin is likely.

  • How long does CONVENIA last or stay in the system of a dog or cat?

    As with any medication, it takes some time for the body to completely eliminate a drug. A drug’s half-life is the time it takes to eliminate half of the drug from the body. The half-life of CONVENIA is 6.9 days in cats and 5.5 days in dogs.3 After this time, the drug continues to decline in concentration and could exist in small amounts for up to 65 days.3 This does not mean that CONVENIA works for this long or, if there is a side effect, that the side effect will last that long. If you have any questions or concerns, please call Zoetis at 888-ZOETIS1 (888-963-8471). Find DVM product information »

  • How often can my dog or cat receive a shot or injection of CONVENIA?

    For cats, CONVENIA should be administered as a single, one-time injection. For dogs, a veterinarian may later administer a second dose under specific circumstances if your dog’s response to therapy is not yet complete.

  • Have there been any reported adverse reactions or side effects to CONVENIA?

    Allergic reactions to CONVENIA are possible. The primary side effects reported with CONVENIA injections in cats and dogs are vomiting, diarrhea, lethargy and decreased appetite. These side effects are uncommon, similar to the incidence rates of other antibiotics. Zoetis takes its responsibility to collect information on side effects very seriously. We have a call center where you can report any adverse reactions or ask any questions. Please call Zoetis at 888-ZOETIS1 (888-963-8471).


  • What are the benefits of CONVENIA?

    An injection of CONVENIA, delivered by your veterinarian, provides your pet with:

    1. Fast treatment: Reaches peak antibiotic blood levels within 6.2 hours and works around the clock for up to 14 days to eliminate common bacterial skin infections and their signs.*
    2. Stress-free dosing: Up to two weeks of treatment with one injection*,1,2 means your pet doesn’t have to take daily pills, and you don’t have to worry about keeping a dosing schedule.
    3. Peace of mind: Confidence that your pet is getting the full course of medication recommended by your veterinarian.

  • The animal shelter where I volunteer serves many homeless pets with skin conditions. Do you have a shelter outreach program?

IMPORTANT SAFETY INFORMATION: People with known hypersensitivity to penicillin or cephalosporins should avoid exposure to CONVENIA. Do not use in dogs or cats with a history of allergic reactions to penicillins or cephalosporins. Side effects for both dogs and cats include vomiting, diarrhea, decreased appetite/anorexia and lethargy. See full Prescribing Information.

* In clinical studies, a single injection of CONVENIA was clinically equivalent to a 14-day antibiotic regimen.

In a U.S. efficacy study, only 14% of dogs treated for skin infections required a second injection.
