29/11/2021 SPC Update

Please note changes

4.5.i. Due to the significant likelihood of cross-contamination of non-treated animals with this product due to grooming (licking), all animals in a group should be treated at the same time and treated animals should be kept separately from non-treated animals throughout the withdrawal period. Non-compliance with this recommendation may lead to residues violations (see section 4.11) or in very rare cases, it can lead to adverse events (see section 4.6) in non-treated animals.

It is not advisable to administer the product when Hypoderma lineatum larvae are localised in the periaesophagic region, or when Hypoderma bovis larvae are situated in the spinal canal. Seek professional veterinary advice to determine the best period of use.
