For oral administration in the food at a dose rate of 0.3 mg dembrexine per kg bodyweight twice daily: for example, for a 500kg horse, 30 g (6 level measures) of powder twice daily.
For small horses, ponies and foals the dose is administered pro rata according to the bodyweight, i.e. at a rate of 2 level measures per 170 kg bodyweight.
Add to the feed immediately prior to administration. Discard any remaining medicated feed.
An improvement in clinical signs is usually seen within five days. Treatment should be continued until complete remission occurs (usually a total period of 12 to 14 days) but should not exceed 28 days. The horse's condition should be reassessed after this period before any further treatment is proposed.
In cases complicated by the presence of micro-organisms or where pyrexia is present, the simultaneous use of suitable chemotherapeutic agent is recommended.
