To obtain optimal benefit from the action of Dectomax solution for injection, it is recommended that cattle which are set-stocked should be treated at turnout and eight weeks later. Studies have demonstrated that, used in this way, Dectomax will reduce the build-up of infective larvae on pasture and can protect animals from parasitic gastro-enteritis and parasitic bronchitis throughout the grazing season. To obtain these results, all animals must be included in the programme and untreated cattle must not be introduced on the pasture. Treated cattle should always be monitored according to good husbandry practices. Treatment with Dectomax solution for injection at turnout and eight weeks later of cattle set-stocked for the grazing season can protect against clinical disease caused by lungworm and may allow the development of naturally acquired immunity. However, due to the unpredictable nature of lungworm epidemiology, clinical signs of lungworm disease may on occasion be seen, particularly towards the end of the grazing season, if the season is long. If this occurs, cattle should be further treated with an anthelmintic effective against lungworm.

Dosage and administration:
Dectomax is a clear, sterile solution. In common with other non-aqueous formulations the product contains no antimicrobial preservative. Dry, sterile equipment and aseptic procedures should therefore be used when administering Dectomax to animals. Swab the septum before removing the dose. When the temperature of the formulation is below 5°C, syringeability may be improved by gently warming the injecting equipment and product.

When treating groups of animals, use only the Dectomax automatic dosing device and vented draw-off apparatus. When treating individual animals syringes must be filled from the vial through a dry, sterile draw-off needle that has been placed in the vial stopper. Vial stoppers must not be broached more than 20 times.

To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.

A single treatment of 1ml (10mg doramectin) per 50kg bodyweight, equivalent to 200mcg/kg bodyweight, administered in the region of the neck by subcutaneuous injection.

A single treatment of 1ml 10mg doramectin) per 33kg bodyweight, equivalent to 300 mcg/kg bodyweight, administered by intramuscular injection for the treatment and control of Psoroptes ovis (sheep scab mite) and adult Nematodirus battus. In addition, adequate bio-security measures should be implemented to prevent re-infestation. Ensure that all sheep which have been in contact with infested sheep are treated. After treatment contact between treated infected and untreated uninfected flocks must be avoided for at least 14 days.
