For the treatment of pain and inflammation associated with degenerative joint
disease in dogs in cases where continuous treatment exceeding one month is
indicated.
Do not use in dogs less than 12 months of age and/or less than 5 kg body weight.
Do not use in dogs suffering from gastro-intestinal disorders including ulceration
and bleeding.
Do not use where there is evidence of a haemorrhagic disorder.
Do not use in cases of impaired renal or hepatic function.
Do not use in cases of cardiac insufficiency.

Issued: October 2023
AN: 01444/2022
Do not use in pregnant, breeding or lactating dogs.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Do not use in case of known hypersensitivity to sulphonamides.
Do not use concomitantly with glucocorticoids or other Non-Steroidal Anti-
Inflammatory Drugs (NSAIDs), see section 4.8.
Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there is a
potential risk of increased renal toxicity.
Dogs aged 12 months or more:
Common
(1 to 10 animals / 100 animals treated):
Vomiting, Diarrhoea.Uncommon
(1 to 10 animals / 1,000 animals
treated):
Apathy, Appetite loss.
Bloody diarrhoea, Melaena.
Renal disorder (degradation of renal
biochemistry parameters and impaired
renal function).*
Rare
(1 to 10 animals / 10,000 animals
treated):
Gastric ulcer, Small intestine ulcer.
*In rare cases these adverse reactions may be fatal.
If an adverse event following the administration of Trocoxil occurs, no further tablets
should be administered and general supportive therapy, as applied to clinical
overdose with NSAIDs, should be applied. Particular attention should be paid to
maintaining haemodynamic status.
Gastrointestinal protectants and parenteral fluids, as appropriate, may be required
for animals that experienced gastrointestinal or renal adverse events. Veterinarians
should be aware that clinical signs of adverse events may continue when
supportive therapy (such as gastro protectants) is discontinued.

Issued: October 2023
AN: 01444/2022
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian,
to either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See section “Contact details”
of the package leaflet.
Do not administer other NSAIDs or glucocorticoids concurrently or within 1 month of
the last administration of Trocoxil.

i. Special precautions for use in animals
Mavacoxib exhibits an extended plasma half life (up to > 80 days, see section 5.2)
due to its low rate of elimination. This corresponds to a duration of effect of 1-2
months after administration of the second dose (and following doses). Care should
be taken to avoid treatment of animals that might not tolerate prolonged NSAID
exposure. A maximum treatment administration of 6.5 months continuous therapy is
recommended so as to manage plasma levels of mavacoxib in animals which
exhibit reduced elimination
Animals should undergo a thorough clinical examination before commencing
treatment with Trocoxil and appropriate laboratory tests to monitor haematology
and clinical chemistry are recommended. Animals with evidence of impaired renal
or hepatic function, or with evidence of a protein or blood losing enteropathy are not
suitable for treatment with Trocoxil. It is recommended to repeat the clinical
examination one month after commencing treatment with Trocoxil and prior to
administration of the third dose with additional monitoring of clinical pathology as
appropriate during treatment.
Mavacoxib is excreted via bile and in dogs with hepatic disorders reduced
elimination and thus excessive accumulation could occur. For this reason, dogs
with hepatic disorders should not be treated.
Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there is a
potential risk of increased renal toxicity. Concurrent administration of potentially
nephrotoxic medicinal products should be avoided.
Ensure appropriate hydration and haemodynamic status when animals receiving
Trocoxil undergo anaesthesia and/or surgical procedures or develop conditions
which may result in dehydration or compromised haemodynamic status. The key
aim of intervention is to maintain renal perfusion. Patients with underlying renal
disease may experience exacerbation or decompensation of their renal disease
while on NSAID therapy. (See also section 4.6).

ii. Special precautions to be taken by the person administering the veterinary
medicinal product to animals
In case of accidental self-ingestion, seek medical advice immediately and show the
package leaflet or the label to the physician.
Ingestion of the product may be harmful for children, and prolonged
pharmacological effects leading to e.g. gastrointestinal disorders may be observed.
To avoid accidental ingestion, administer the tablet to the dog immediately after
removal from the blister packaging.
People with known hypersensitivity to NSAIDs should avoid contact with the
veterinary medicinal product.
Do not eat, drink, or smoke when handling the product. Wash hands after handling
the product.
Special precautions for the protection of the environment:
Not applicable.
No drug interaction studies have been performed. In common with other NSAIDs,
Trocoxil should not be administered simultaneously with other NSAIDs or
glucocorticosteroids. Risks for interactions have to be accounted for throughout the
effect period i.e. 1-2 months after administration of Trocoxil. Dogs should be
carefully monitored if Trocoxil is administered simultaneously with an anticoagulant.
NSAIDs are highly bound to plasma proteins and may compete with other highly
bound substances, such that concomitant administration may result in toxic effects.
Pre-treatment with other anti-inflammatory substances may result in additional or
increased adverse effects. To avoid such effects when Trocoxil is to be
administered in replacement of another NSAID, ensure an appropriate treatment-
free period of at least 24 hours before administering the first dose of Trocoxil. The
treatment-free period should however, take into account the pharmacology of the
medicinal products used previously. Should another NSAID be administered after
Trocoxil treatment, a treatment-free period of at least ONE MONTH should be
ensured to avoid adverse effects.
Concurrent administration of potentially nephrotoxic veterinary medicinal products
should be avoided.
This veterinary medicinal product does not require any special storage conditions.
