Chanazone is indicated for the treatment of musculoskeletal conditions in the horse where relief from pain and a reduction in the associated inflammation is required, e.g. in lameness associated with osteoarthritic conditions, bursitis, laminitis and soft tissue inflammation, particularly where continued mobility is considered desirable.
It is also of value in limiting post surgical inflammation, myositis and other soft tissue inflammation.
It can be used as an anti-pyretic where this is considered advisable e.g. in viral respiratory infections.
Do not use in animals with known hypersensitivity to the active substance.
Use is contra-indicated in animals suffering from cardiac, hepatic or renal disease, where there is the possibility of gastro-intestinal ulceration or bleeding or where there is evidence of a blood dyscrasia.
Do not use in animals suffering from thyroid disease.
Do not use in animals with severe hypertonia.
Do not use in animals with lesions in the intestinal mucosa, caused by parasitic infestations.
In common with other NSAIDs that inhibit prostaglandin synthesis, there may be gastric and/or renal intolerance. This is usually associated with overdosage and such events are rare. Recovery is usual on cessation of treatment and following the initiation of supportive symptomatic therapy.
Blood dyscrasia may occur.
Ponies are very sensitive to gastric ulceration with this product, even at therapeutic doses (diarrhoea, ulceration in the mouth and hypoproteinaemia may also be seen).
If adverse reactions occur, treatment should be discontinued and the advice of a veterinarian should be sought.
If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary surgeon.
