Convenia (cefovecin sodium) is a cephalosporin antibiotic that is administered by veterinarians to treat certain skin infections in animals, including strains of Staphylococcus. The drug has been approved by government agencies in the US and Europe, but adverse reactions are possible and some pet owners report severe symptoms following treatment.
Common Side Effects
Field tests conducted by Convenia's manufacturer indicate that the drug can produce several notable negative symptoms in animal patients, which are indicated on the warning label. These include diminished appetite, diarrhea, lethargy, body tremors and vomiting. Local swelling at the site of injection is also possible. Pets with these symptoms should be seen by a vet immediately, as malnourishment and dehydration from fluid loss can cause lasting harm to your furry friend's health.
Animals that are sensitive to penicillin and related antibiotics can experience a severe reaction after an injection. Humans handling the drug can also be affected if they are hypersensitive. Take your pet to the vet if any new symptoms emerge in the hours or days following treatment. Signs of severe allergic reaction include skin rash, labored breathing, bodily weakness and seizures.
The long-term effects of Convenia are still unknown, as are the impact that the drug has on pregnant and very young animals. It is also possible for the antibiotic to interact negatively with other medicines, including non-steroidal anti-inflammatory drugs.
