Skin and soft tissue infections in dogs:

A single subcutaneous injection. If required, treatment may be repeated at 14 day intervals up to a further three times. In accordance with good veterinary practice, treatment of pyoderma should be extended beyond complete resolution of clinical signs.

Severe infections of the gingival and periodontal tissues in dogs:

A single subcutaneous injection of 8 mg/kg bodyweight (1 ml per 10 kg bodyweight).

Skin and soft tissue abscesses and wounds in cats:

A single subcutaneous injection. If required, an additional dose may be administered 14 days after the first injection.

Urinary tract infections in dogs and cats:

A single subcutaneous injection.

To ensure a correct dosage, bodyweight should be determined as accurately as possible to avoid underdosing.

Contra-indications, warnings, etc

Do not use in cases of hypersensitivity to cephalosporin or penicillin antibiotics.

Do not use in small herbivores (including guinea pigs and rabbits).

Do not use in dogs and cats less than 8 weeks old.

On very rare occasions gastrointestinal signs, including emesis and/or diarrhoea have been observed.

In very rare cases neurological signs and injection site reactions have been reported after use.

If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary surgeon.

It is prudent to reserve third generation cephalosporins for the treatment of clinical conditions, which have responded poorly, or are expected to respond poorly, to other classes of antimicrobials or first generation cephalosporins. Use of the product should be based on susceptibility testing and take into account official and local antimicrobial policies.

The fundamental requirement of the treatment of periodontal disease is mechanical and/or surgical intervention by the veterinarian.

The safety of Convenia in dogs and cats has not been established during pregnancy and lactation. Treated animals should not be used for breeding for 12 weeks after the last administration.

The safety of Convenia has not been assessed in animals suffering from severe renal dysfunction.

Pyoderma is often secondary to an underlying disease. It is, therefore, advisable to determine the underlying cause and to treat the animal accordingly.

Caution should be exercised in patients that have previously shown hypersensitivity reactions to cefovecin, other cephalosporins, penicillins, or other drugs. If an allergic reaction occurs, no further administrations of cefovecin should be administered and appropriate therapy for beta-lactam hypersensitivity should be instituted. Serious acute hypersensitivity reactions may require treatment with epinephrine and other emergency measures, including oxygen, intravenous fluids, intravenous antihistamine, corticosteroids, and airway management, as clinically indicated. Veterinarians should be aware that reappearance of the allergic symptoms may occur when symptomatic therapy is discontinued.

Concurrent use of other substances that have a high degree of protein binding (e.g. furosemide, ketoconazole, or non-steroidal anti-inflammatory drugs (NSAIDs)) may compete with cefovecin binding and thus may cause adverse effects.

Repeated dosing (eight administrations) in 14-day intervals at five times the recommended dose was tolerated well in young dogs. Slight and transient injection site swellings were observed after the first and second administration. A single administration of 22.5 times the recommended dose caused transient oedema and discomfort at the injection site. Repeated dosing (eight administrations) in 14-day intervals at five times the recommended dose was tolerated well in young cats. A single administration of 22.5 times the recommended dose caused transient oedema and discomfort at the injection site.

In the absence of compatibility studies, this veterinary medicinal product must not be mixed with other veterinary medicinal products.

User warnings:

Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross sensitivity to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

Do not handle this product if you know you are sensitised or if you have been advised not to work with such preparations.

Handle this product with care to avoid exposure, taking all recommended precautions.

If you develop symptoms following exposure, such as a skin rash, you should seek medical advice and show the doctor this warning. Swelling of the face, lips or eyes or difficulty in breathing are more serious symptoms and require urgent medical attention. If you know you are allergic to penicillins or cephalosporins, avoid contact with contaminated litter. In the event of contact, wash skin with soap and water.

Pharmaceutical precautions
