Cefovecin
También conocido como: Convenia
**What is Cefovecin (Convenia)?** Cefovecin is a long-acting antibiotic given by injection at the veterinary clinic. It is highly effective for treating certain skin and soft tissue infections. **Key Points for Pet Owners:** * **Convenience:** A single injection provides days to weeks of antibiotic therapy, eliminating the need for you to give daily pills or liquids at home. * **Long-Lasting:** This drug stays in your pet's body for approximately 2 months (up to 65 days) after the injection. * **Side Effects:** While generally very safe, some pets may experience tiredness, decreased appetite, or vomiting. Because the drug stays in the system for a long time, if your pet has an allergic reaction or severe side effect, they may require veterinary care for an extended period. * **Action Required:** Contact your veterinarian immediately if you notice any facial swelling, hives, severe vomiting, diarrhea, or extreme lethargy after your pet receives this injection.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

What it is used for
- Skin infections due to S. intermedius or S. canis (Group G) (USA Label)
- Skin and soft tissue infections (UK Label)
- Severe infections of the gingival and periodontal tissues (UK Label)
- Urinary Tract Infections (UK Label)
- Skin, soft tissue, urinary tract infections, and severe periodontal disease

How it is given
Possible side effects
- Lethargy and depression
- Anorexia
- Vomiting
- Mild to moderate increases in liver enzymes (ALT, GGT)
- Increases in BUN and moderately elevated serum creatinine (observed in cats)
- Injection site irritation, vocalization, and transient edema
- Hypersensitivity reactions and anaphylaxis (rare but potentially fatal)
- Myelotoxicity creating toxic neutropenia (rare class effect)
- Anemia, thrombocytopenia, and prolonged coagulation times (rare class effect)
Cautions & contraindications
- Known allergy or hypersensitivity to cefovecin, other cephalosporins, or penicillins (beta-lactams)
- Small herbivores (e.g., guinea pigs, rabbits) due to risk of fatal dysbiosis
- Dogs or cats less than 4 months of age (USA label) or less than 8 weeks of age (UK label)
- > **Prolonged Duration Warning:** Because cefovecin can persist in the body for up to 65 days, any adverse reactions (such as hypersensitivity or gastrointestinal upset) may require prolonged symptomatic and supportive treatment. * **Renal Impairment:** Cefovecin is primarily eliminated via renal mechanisms. Use with caution in animals with severe renal dysfunction. * **Breeding/Lactation:** Safe use in breeding or lactating animals has not been definitively established, though cephalosporins are generally considered safe. Weigh risks vs. benefits. * **Laboratory Interference:** May cause false-positive urine glucose (copper reduction methods), falsely elevated creatinine (Jaffe reaction at high doses), falsely lowered albumin, and false-positive direct Coombs' tests.
Drug interactions
- Carprofen: May compete for plasma protein binding sites, potentially increasing the free (active) concentrations of either drug.
- Furosemide: May compete for plasma protein binding sites.
- Doxycycline: May compete for plasma protein binding sites.
- Ketoconazole: May compete for plasma protein binding sites.
- NSAIDs, Propofol, Cardiac, Anticonvulsant, and Behavioral medications: Concurrent use of highly protein-bound drugs may compete with cefovecin binding and cause adverse reactions, though actual clinical significance is not fully established.
- NSAIDs: Competition for plasma protein binding, potentially altering free drug concentrations
