Do not use concomitantly with corticosteroids or other non-steroidal anti-
inflammatory drugs (NSAIDs).

and diarrhoea.

Generally of a transitory nature and reversible when treatment is stopped.
If adverse reactions like vomiting, repeated diarrhoea, faecal occult blood, sudden
weight loss, anorexia, lethargy, degradation of renal or hepatic biochemistry
parameters occur, use of the product should be stopped and the advice of a
veterinarian should be sought. As with other NSAIDs, serious adverse effects can
occur and, in very rare cases, may be fatal.
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 the package leaflet for
respective contact details.

Special precautions for use in animals
The recommended dose, see section 4.9, should not be exceeded.
Use in very young animals, or animals with suspected or confirmed impairment of
renal, cardiac or hepatic function may involve additional risk. If such use cannot be
avoided, those dogs require careful veterinary monitoring.
Avoid use in dehydrated, hypovolaemic or hypotensive animals, as there is a
potential risk of increased renal toxicity. Concurrent administration of potentially
nephrotoxic drugs should be avoided.
Use this product under strict veterinary monitoring where there is a risk of
gastrointestinal bleeding, or if the animal previously displayed intolerance to
NSAIDs. Renal and/or hepatic disorders have been reported in very rare cases in
dogs administered the recommended treatment dose. It is possible that a proportion
of such cases had sub-clinical renal or hepatic disease prior to the commencement
of therapy. Therefore, appropriate laboratory testing to establish baseline renal or
hepatic biochemistry parameters is recommended prior to and periodically during
administration.
The treatment should be discontinued if any of these signs are observed: repeated
diarrhoea, vomiting, faecal occult blood, sudden weight loss, anorexia, lethargy,
degradation of renal or hepatic biochemistry parameters.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Wash hands after use of the product.
In case of accidental ingestion, seek medical advice immediately and show the
package leaflet or the label to the physician.
Divided tablets should be returned to the original package.
Special precautions for the protection of the environment
Not applicable.
Other precautions
Not applicable.
increased adverse effects and accordingly a treatment-free period with such drugs
should be observed for at least 24 hours before the commencement of treatment
with the veterinary medicinal product. The treatment-free period, however, should
take into account the pharmacokinetic properties of the products used previously.
The veterinary medicinal product must not be administered in conjunction with other
NSAIDs or glucocorticosteroids. Gastrointestinal tract ulceration may be
exacerbated by corticosteroids in animals given non-steroidal anti-inflammatory
drugs.
Concomitant treatment with molecules displaying action on renal flow, e.g. diuretics
or Angiotensin Converting Enzyme (ACE) inhibitors, should be subject to clinical
monitoring. Concurrent administration of potentially nephrotoxic drugs should be
avoided as there might be an increased risk of renal toxicity. As anaesthetic drugs
may affect renal perfusion, the use of parenteral fluid therapy during surgery should
be considered to decrease potential renal complications when using NSAIDs peri-
operatively.
Concurrent use of other active substances that have a high degree of protein
binding may compete with firocoxib for binding and thus lead to toxic effects.
Store in the original package.
Place the tablet on a
flat surface, with its
scored side facing up

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
In dogs ten weeks of age, at the start of treatment, at dose rates equal or greater to
25 mg/kg/day (5 times the recommended dose) for three months, the following signs
of toxicity were observed: bodyweight loss, poor appetite, changes in the liver
(accumulation of lipid), brain (vacuolisation), duodenum (ulcers) and death. At dose
rates equal or greater to 15 mg/kg/day (3 times the recommended dose) for six
months, similar clinical signs were observed, albeit that the severity and frequency
were less and duodenal ulcers were absent.
Revised: July 2024
AN: 00396/2023 Page 5 of 7
In those target animal safety studies, clinical signs of toxicity were reversible in
some dogs following cessation of therapy.
In dogs seven months of age, at the start of treatment, at dose rates greater than or
equal to 25 mg/kg/day (5 times the recommended dose) for six months,
gastrointestinal adverse effects, i.e. vomiting were observed.
Overdose studies were not conducted in animals over 14 months of age.
If clinical signs of overdosing are observed, discontinue treatment.
4.11 Withdrawal period(s)
Not applicable.
