Article 4
1. Biocidal products, feed additives or other substances used in drinking water shall not be used simultaneously with a veterinary medicinal product where there is evidence of negative interactions or incompatibilities between those products and the veterinary medicinal product when added to drinking water. 2. Veterinary medicinal products containing an anticoccidial or antihistomonal active substance shall not be used in feed containing the same substance as a feed additive authorised as a coccidiostat or a histomonostat with a maximum content. 3. For active substances other than anticoccidial or antihistomonal substances, where the active substance in the veterinary medicinal product is the same as a substance in a feed additive contained in the feed, the total content of that active substance in the feed once the veterinary medicinal product has been mixed into it or added onto its surface shall not exceed the maximum content set out in the prescription.
