Chanazone® Oral Powder for Horses 1g

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.
