The dosage is 8.8 mg of the active substance per kg body weight daily, (equivalent to 10 ml solution per 142 kg body weight) administered in the drinking water of pigs for 3 to 5 days, depending on the severity of the infection and/or the duration of the disease. To ensure an intake of 8.8 mg/kg daily it is important to know the weight of the animals to be treated and to measure accurately their drinking water consumption. Administer the calculated dose (based on the animals’ weight) in approximately one half of the daily water requirements, to ensure consumption of the correct dose. Unmedicated water should then be provided each day after the medicated water has been consumed. Where a water medicator is used the appropriate stock solution should be made up according to the makers’ instructions. Any medicated water not consumed within 24 hours should be discarded. Additionally, water intake levels should be monitored at frequent intervals during medication. Fresh solutions of Tiamvet®-medicated drinking water should be made up each day.
