given pre-operatively at the time of induction of anaesthesia. The use of a 1 ml
graduated syringe is recommended to measure the dose accurately.
Clinical trial evidence in dogs and cats suggests only a single dose of carprofen is
required in the first 24 hours perioperatively; if further analgesia is required in this
period a half dose (2 mg/kg) of carprofen may be given to dogs (but not to cats) as
necessary.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
In dogs, to extend analgesic and anti-inflammatory cover post-operatively, parenteral
therapy may be followed with carprofen tablets at 4 mg/kg/day for up to 5 days.
For administration of the veterinary medicinal product a 21-gauge needle should be
used.
The cap can be punctured up to 20 times. When puncturing more than 20 times, use

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 safe use in the target species:
Do not exceed the recommended dose or duration of treatment.
Due to the longer half life in cats and narrower therapeutic index, particular care
should be taken not to exceed the recommended dose and the dose should not be
repeated.
Use in aged dogs and cats may involve additional risk.
If such use cannot be avoided, such animals may require a reduced dosage and
careful clinical management.
Avoid use in any dehydrated, hypovolaemic or hypotensive animals, as there is a
potential risk of increased renal toxicity.
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.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Care should be taken to avoid accidental self-injection.
Carprofen, in common with other NSAIDs, has been shown to exhibit
photosensitising potential in laboratory animals. Avoid skin contact with the veterinary
medicinal product. Should this occur, wash the affected area immediately.
People with known hypersensitivity to carprofen or to any of the excipients should
avoid contact with the veterinary medicinal product.
