Do not administer to horses, cattle or pigs that have previously shown a hypersensitivity to ketoprofen. Do not administer other non-steroidal anti-inflammatory drugs (NSAIDs) concurrently or within 24 hours of each other. Use is contraindicated in animals suffering from cardiac, hepatic or renal disease, where there is the possibility of gastrointestinal ulceration or bleeding, where there is evidence of a blood dyscrasia or hypersensitivity to the product.

Special warnings for each target species

Use in any animal less than 6 weeks of age or in aged animals may involve additional risk. If such use cannot be avoided animals may require a reduced dosage and careful management. Avoid use in any dehydrated, hypovolaemic or hypotensive animals as there is a potential risk of increased renal toxicity.

Special precautions for use in animals

Avoid intra-arterial injection. Do not exceed the stated dose or duration of treatment.

Special precautions to be taken by the person administering the product to animals

In case of accidental self-injection seek medical advice. Wash hands after use. Avoid splashes on the skin and eyes. Irrigate thoroughly with water should this occur. If irritation persists seek medical advice.

Adverse reactions

In common with all NSAIDs, due to their action of inhibition of prostaglandin synthesis, there can be the possibility in certain individuals of gastric or renal intolerance.

Use during pregnancy, lactation or lay

As the effects of ketoprofen on fertility, pregnancy or foetal health of horses have not been determined, Ketofen 10% should not be administered to pregnant mares. Ketofen 10% may be given to pregnant and lactating cattle. It is indicated for use in lactating sows.


Some NSAIDs may be highly bound to plasma proteins and compete with other highly bound drugs which can lead to toxic effects. Concurrent administration with nephrotoxic drugs should be avoided.

Amounts to be administered and administration route


For use in musculoskeletal conditions, the recommended dosage is 2.2 mg ketoprofen/kg i.e. 1 ml/45 kg bodyweight, administered by intravenous injection once daily for up to 3 to 5 days.

For use in equine colic, the recommended dosage is 2.2 mg/kg (1 ml/45 kg) bodyweight, given by intravenous injection for immediate effect. A second injection may be given if colic recurs.

The recommended dose is 3 mg ketoprofen/kg bodyweight, i.e. 1 ml/33 kg bodyweight, administered once by deep intramuscular injection.

Does it work?

How does this drug work? My 6yr old horse has just started treatment with it for a low level osteosteoarthritis in his right front fetlock. Can he lead a normal riding club level type life? How many years will he be rideable for?

Ketofen is an anti-inflammatory drug which provides some relief from pain. It will not cure the arthritis in any way, bit helps reduce the symptoms. However arthritis varies considerably between different individuals and it is very difficult to predict how it will progress over time. Lots of factors can influence it. General advice would be to keep exercise to a moderate level. Strenuous or prolonged periods of exercise should always be avoided. Ideally a similar daily routine should be maintained every day, rather than some days with minimal exercise and others which much more. Provide a gentle warm-up period at the start of exercise and very importantly keep the horse slightly lean. Many horses with arthritis are slightly overweight and many people find this appearance quite pleasing, but it puts a great deal more wear and tear for the joints to deal with. A lean horse will have much less trouble from arthritis. Your horse might do well for many years, but a level of weakness will remain.
