Typical undesirable effects associated with NSAIDs, such as vomiting, soft
faeces/diarrhea, faecal occult blood, loss of appetite and lethargy have been
reported. These adverse reactions occur generally within the first treatment week
and are in most cases transient and disappear following termination of the
treatment but in very rare cases may be serious or fatal.
If adverse reactions occur, use of the product should be stopped and the advice
of a veterinarian should be sought.
As with other NSAIDs there is a risk of rare renal or idiosyncratic hepatic adverse
events.

Refer to Sections 4.3 and

Special precautions for use in animals
Use in dogs less than 6 weeks of age, or in aged dogs, may involve additional risk.
If such a use cannot be avoided, dogs may require careful clinical management.
Avoid use in any dehydrated, hypovolaemic or hypotensive dog, as there is a
potential risk of increased renal toxicity.
Concurrent administration of potential nephrotoxic drugs should be avoided.
NSAIDs can cause inhibition of phagocytosis and hence in the treatment of
inflammatory conditions associated with bacterial infection, appropriate concurrent
antimicrobial therapy should be instigated.
Do not administer other NSAIDs concurrently or within 24 hours of each other.
Some NSAIDs may be highly bound to plasma proteins and compete with other
highly bound drugs, which can lead to toxic effects.
Special Precautions to be taken by the Person Administering the Veterinary
Medicinal Product to Animals
In the event of accidental ingestion of the tablets, seek medical advice and show
the doctor the package leaflet. Wash hands after handling the product.
Carprofen must not be administered with glucocorticoids.
Refer also to section 4.5
Store in a dry place in the original package. Protect from light.
Not applicable.
