Paragraph 17 Writing the prescription
The person who writes the prescription must—
give a copy to the person incorporating the veterinary medicinal product into the feedingstuffs or to the distributor of the feedingstuffs;
give one copy to the keeper of the animals to be treated;
keep a copy himself.
He must be satisfied that—
there is no undesirable interaction between the veterinary medicinal product and any feed additive used in the feedingstuffs; and
the active substance of the veterinary medicinal product is not the same as an active substance in any feed additive used in the feedingstuffs.
For the avoidance of doubt, a veterinary surgeon may prescribe either a veterinary medicinal product authorised for that species and condition, or under the cascade.
The requirement for a written prescription does not apply in relation to a veterinary medicinal product supplied to a person specified in paragraph 6(2) for incorporation into feedingstuffs in their premises, but in this case paragraph 5 of Schedule 3 applies in relation to the supply of the veterinary medicinal product.
It is an offence to fail to comply with this paragraph.
