Active Ingredient:



Each sachet of 5g contains 1g of Phenylbutazone. Off white to yellow powder. 


The product 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.

Phenylbutazone powder can be used as an anti-pyretic where this is considered advisable e.g. in viral respiratory infections.

Dosage and administration:

For oral use.
The recommended dose rate is 4.4 – 8.8 mg/kg per day.
For each 450 kg bodyweight the following dosage guide should be used according to individual response:
Day 1 - 4.4 mg phenylbutazone/kg of bodyweight twice daily, (equivalent to two sachets or 10 g of the product twice daily).
Day 2 - 4 2.2 mg phenylbutazone /kg of bodyweight twice daily, (equivalent to one sachet or 5 g of the product twice daily) followed by 2.2 mg phenylbutazone /kg of bodyweight daily, (equivalent to one sachet or 5 g of the product daily) or on alternate days as required.
If no response is evident after 4-5 days, discontinue treatment. Hay may delay the absorption of phenylbutazone and so the onset of a clinical effect. It is advisable not to administer hay immediately prior to, or during the administration of the product.
For ease of administration the product may be mixed with a quantity of bran or oats before each treatment.
The therapeutic index of phenylbutazone is low. Do not exceed the stated dose or duration of treatment.

Horses: Not for use in horses intended for human consumption. Treated horses should never be slaughtered for human consumption. The horse must be declared as not intended for human consumption under national horse passport regulation.
