Summary for the public


What is Convenia?

Convenia contains cefovecin, an antibiotic which is given by injection (under the skin). It is used for dogs and cats.

There are two vials in each pack of Convenia, one vial containing a powder, and one vial containing the diluent. The powder is dissolved in the diluent before use to make up a solution for injection.


What is Convenia used for?

Convenia is used to treat infections caused by certain specific bacteria (see the SPC for further details). It is generally given as a single injection, and the effect of the injection lasts for up to 14 days. Depending on the infection concerned, the injection can be repeated if necessary (up to three times).

Convenia is used in dogs to treat skin and soft tissue infections; these are infections on the skin and in the layers just below the skin, such as wounds, abscesses and pyoderma (a skin infection with a rash and pustules). It is also used in dogs to treat urinary tract infections caused by certain specific bacteria.

Convenia is used in cats to treat skin and soft tissue infections, such as wounds and abscesses. It is also used in cats to treat urinary tract infections caused by certain specific bacteria. 


How does Convenia work?

The active substance in Convenia is cefovecin which belongs to a class of antibiotics called third generation cephalosporins. All these cephalosporin antibiotics, including cefovecin, kill bacteria by disrupting the building of the bacterial cell walls, so the bacteria die and the infection is cured. Like other antibiotics, cefovecin is not effective against all types of bacteria.

Cefovecin differs from other similar cephalosporin antibiotics as it stays in the dog’s or cat’s body for a very long time after it has been injected. One injection lasts for up to 14 days.


How has Convenia been studied?

Data from laboratory studies with different bacteria showed that cefovecin was effective against the bacteria specified in the product information (SPC and package leaflet).

Convenia has been studied in dogs with skin and soft tissue infections (where it was compared to another antibiotic containing amoxicillin and clavulanic acid) and in dogs with urinary tract infections (where it was compared to another cephalosporin antibiotic, cefalexin).

Convenia has also been studied in cats with skin and soft tissue infections (where it was compared to another antibiotic containing amoxicillin and clavulanic acid), and in a small study in cats with urinary tract infections, where it was compared with cefalexin. The studies measured the rate at which the infections were cured.


What benefit has Convenia shown during the studies?

In all studies, Convenia was as effective in curing the infection as the comparator antibiotic. Convenia has the benefit of a long duration of activity.


What is the risk associated with Convenia?

No side-effects have been reported with Convenia to date. However, it should not be used in dogs or cats which have shown an allergy to any cephalosporin or penicillin-type antibiotics.

Convenia should also not be used in dogs or cats of less than 8 weeks old, or in dogs or cats with severe kidney problems (renal dysfunction).

It would be dangerous to use Convenia in other animals such as guinea pigs and rabbits (it is not licensed for use in these species). As no studies have been made in breeding animals with Convenia and it has an exceptionally long duration in the body, Convenia should not be used in pregnant or lactating dogs or cats. Treated animals should not be used for breeding for 12 weeks after the last injection of Convenia.


What are the precautions for the person who gives the medicine or comes into contact with the animal?

Cephalosporin and penicillin antibiotics can cause allergies in humans, and sometimes these allergies can be very serious. Convenia should therefore not be handled by anyone who is hypersensitive (allergic) to such antibiotics, or by anyone who has been advised not to work with them. Anyone allergic to penicillins or cephalosporins should also avoid contact with litter used by dogs or cats treated with Convenia.

Convenia should be handled with care and all the recommended precautions be taken to avoid exposure to the product. If any symptoms occur after accidental exposure to Convenia, for example a skin rash, then the advice of a doctor should be sought immediately. Swelling of the face, lips or eyes, or any difficulty breathing are more serious symptoms and require urgent medical attention.


Why has Convenia been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Convenia exceed the risks for the treatment of dogs and cats with certain specified skin, soft tissue and urinary tract infections and recommended that Convenia should be given a marketing authorisation. The benefit-risk balance may be found in module 6 of this EPAR.

4.5
Special precautions for use
Special precautions for use in animals
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 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.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
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.
3
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.
4.6 Adverse reactions (frequency and seriousness)
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 the use of the
product.
4.7 Use during pregnancy, lactation or lay
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.
4.8 Interaction with other medicinal products and other forms of interaction
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.
4.9
Amounts to be administered and administration route
Skin and soft tissue infections in dogs:
A single subcutaneous injection of 8 mg/kg bodyweight (1 ml per 10 kg bodyweight). 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 of 8 mg/kg bodyweight (1 ml per 10 kg bodyweight). 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 of 8 mg/kg bodyweight (1 ml per 10 kg bodyweight).
To reconstitute, withdraw 10 ml of the supplied diluent from its vial and add to the vial containing the
lyophilised powder. Shake the vial until the powder is seen to have fully dissolved.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Antibacterials for systemic use (cephalosporins).
ATCvet code: QJ01DD91.
5.1
Pharmacodynamic properties
Cefovecin is a third generation cephalosporin with a broad-spectrum of activity against Gram-positive and
Gram-negative bacteria. It differs from other cephalosporins in that it is highly protein bound and has a
long duration of activity. As with all cephalosporins, the action of cefovecin results from the inhibition of
bacterial cell wall synthesis; cefovecin has bactericidal activity.
Cefovecin exhibits in-vitro activity against Staphylococcus pseudintermedius and Pasteurella multocida
which are associated with canine and feline skin infections. Anaerobic bacteria such as Bacteroides spp.
and Fusobacterium spp. collected from feline abscesses were shown to be susceptible. Porphyromonas
gingivalis and Prevotella intermedia collected from canine periodontal disease were also shown to be
susceptible. In addition, cefovecin exhibits in-vitro activity against Escherichia coli which is associated
with canine and feline urinary tract infections.
In-vitro activity against these pathogens as well as against other skin and urinary tract pathogens collected
during a European (Denmark, France, Germany, Italy and United Kingdom) MIC survey (1999 – 2000)
and during European (France, Germany, Spain and United Kingdom) clinical efficacy and safety field
studies (2001 – 2003) are listed below. Periodontal isolates were collected during a European (France and
Belgium) clinical efficacy and safety field study (2008).

3
Some of these pathogens (e.g. S. aureus ) exhibited natural in vitro resistance to cefovecin
4
The clinical significance of these in vitro data has not been demonstrated.
Resistance to cephalosporins results from enzymatic inactivation (-lactamase production), from reduced
permeability by porin mutations or change in efflux, or by selection of low-affinity penicillin-binding
proteins. Resistance may be chromosomal or plasmid-encoded and may be transferred if associated with
transposons or plasmids. Cross resistance with other cephalosporins and other beta-lactam antibacterial
agents can be observed.
When applying a proposed microbiological breakpoint of S  2 g/ml, no resistance to cefovecin was
detected in Pasteurella multocida, Fusobacterium spp. or Porphyromonas spp. field isolates. When
applying a proposed microbiological breakpoint of I  4 g/ml, cefovecin resistance in
S. pseudintermedius and beta-haemolytic Streptococci isolates was less than 0.02 % and 3.4 % in
Prevotella intermedia isolates. The percentage of cefovecin resistant isolates in E. coli , Prevotella oralis ,
Bacteroides spp. and Proteus spp. were 2.3 %, 2.7 %, 3.1 % and 1.4 %, respectively. The percentage of
cefovecin resistant isolates in coagulase negative Staphylococcus spp. (e.g. S. xylosus , S. schleiferi ,
S. epidermidis ) is 9.5 %. Pseudomonas spp., Enterococcus spp., and Bordetella bronchiseptica isolates are
inherently resistant to cefovecin.

5.2
Pharmacokinetic particulars
Cefovecin has unique pharmacokinetic properties with extremely long elimination half-lives in both dogs
and cats.
In dogs, when cefovecin was administered as a single subcutaneous dose of 8 mg/kg bodyweight,
absorption was rapid and extensive; peak plasma concentration at 6 hours was 120 g/ml and
bioavailability approximately 99 %. Peak concentrations in tissue cage fluid of 31.9 μg/ml were measured
2 days after administration. Fourteen days after administration, the mean cefovecin concentration in
plasma was 5.6 μg/ml. Plasma protein binding is high (96.0 % to 98.7 %) and the volume of distribution is
low (0.1 l/kg). Elimination half-life is long – approximately 5.5 days. Cefovecin is primarily eliminated
unchanged via the kidneys. At fourteen days after administration, urine concentrations were 2.9 μg/ml.
In cats, when cefovecin was administered as a single subcutaneous dose of 8 mg/kg bodyweight,
absorption was rapid and extensive; peak plasma concentration at 2 hours was 141 g/ml and
bioavailability approximately 99 %. Fourteen days after administration the mean cefovecin concentration
in plasma was 18 g/ml. Plasma protein binding is high (more than 99 %) and the volume of distribution
is low (0.09 l/kg). Elimination half-life is long – approximately 6.9 days. Cefovecin is primarily
eliminated unchanged via the kidneys. At ten and fourteen days after administration, urine concentrations
were 1.3 g/ml and 0.7 g/ml, respectively. Following repeated administrations at the recommended dose,
elevated concentrations of cefovecin were observed in plasma.

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.

ADVICE ON CORRECT ADMINISTRATION
To ensure a correct dosage, body weight should be determined as accurately as possible to avoid
underdosing.
In the absence of compatibility studies, this veterinary medicinal product must not be mixed with other
veterinary medicinal products.
Pyoderma is often secondary to an underlying disease. It is, therefore, advisable to determine the
underlying cause and to treat the animal accordingly.
10. WITHDRAWAL PERIOD
Not applicable.
11. SPECIAL STORAGE PRECAUTIONS
Keep out of the reach and sight of children.
Do not use after the expiry date stated on the carton.
Shelf-life after reconstitution according to directions: 28 days.

As with other cephalosporins, the colour of the reconstituted solution may darken during this period.
However, if stored as recommended, potency is not affected.
Before reconstitution:
Store in a refrigerator (2 C – 8 C). Do not freeze.
Store in the original package in order to protect from light.
After reconstitution:
Store in a refrigerator (2 C – 8 C). Do not freeze.
Store in the original package in order to protect from light.
12. SPECIAL WARNING(S)
For the animal:
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.
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.
For the user:
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:
21
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.
13. SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE
MATERIALS, IF ANY
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal
products should be disposed of in accordance with local requirements.

15. OTHER INFORMATION
Cefovecin is a third generation cephalosporin with a broad-spectrum of activity against Gram-positive and
Gram-negative bacteria. It differs from other cephalosporins in that it is highly protein bound and has a
long duration of activity. As with all cephalosporins, the action of cefovecin results from the inhibition of
bacterial cell wall synthesis; cefovecin has bactericidal activity.
Cefovecin exhibits in vitro activity against Staphylococcus pseudintermedius and Pasteurella multocida
which are associated with canine and feline skin infections. Anaerobic bacteria such as Bacteroides spp.
and Fusobacterium spp. collected from feline abscesses were shown to be susceptible. Porphyromonas
gingivalis and Prevotella intermedia collected from canine periodontal disease were also shown to be
susceptible. In addition, cefovecin exhibits in-vitro activity against Escherichia coli which is associated
with canine and feline urinary tract infections.
Resistance to cephalosporins results from enzymatic inactivation (-lactamase production) or from other
mechanisms. Resistance may be chromosomal or plasmid-encoded and may be transferred if associated
with transposons or plasmids. Cross resistance with other cephalosporins and other beta-lactam
antibacterial agents can be observed. When applying a proposed microbiological breakpoint of S  2
g/ml, no resistance to cefovecin was detected in Pasteurella multocida , Fusobacterium spp. and
Porphyromonas spp. field isolates. When applying a proposed microbiological breakpoint of I  4 g/ml,
cefovecin resistance in S. pseudintermedius and beta-haemolytic Streptococci isolates was less than
0.02 % and 3.4 % in Prevotella intermedia isolates. The percentage of cefovecin resistant isolates in E.
coli , Prevotella oralis , Bacteroides spp. and Proteus spp. were 2.3 %, 2.7 %, 3.1 % and 1.4 %,
respectively. The percentage of cefovecin resistant isolates in coagulase negative Staphylococci spp. (e.g.
S. xylosus , S. schleiferi , S. epidermidis ) is 9.5 %. Pseudomonas spp., Enterococcus spp., and Bordetella
bronchiseptica isolates are inherently resistant to cefovecin.
22
Cefovecin has unique pharmacokinetic properties with extremely long elimination half-lives in both dogs
and cats.
The product is available in a single pack size composed of a vial containing the freeze-dried powder, and a
second vial containing the diluent. Reconstitution yields 10 ml of solution for injection.
