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.
Cattle
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.
Sheep
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.
Suggested dose rates for Psoroptes ovis (sheep scab mite) and Nematodirus battus: 1 ml/33 kg bodyweight (300 mcg/kg). Sheep over 16 kg bodyweight:
Bodyweight | Dose |
17 - 25 kg | 0.75 ml |
26 - 33 kg | 1.0 ml |
34 - 41 kg | 1.25 ml |
42 - 50 kg | 1.5 ml |
51 - 58 kg | 1.75 ml |
59 - 66 kg | 2.0 ml |
67 - 74 kg | 2.25 ml |
75 - 83 kg | 2.5 ml |
84 - 91 kg | 2.75 ml |
92 - 99 kg | 3.0 ml |
In young lambs of less than 16 kg bodyweight seek veterinary advice regarding the use of appropriate sized needles and of 1 ml disposable syringes graduated in increments of 0.1 ml or less. Suggested dose rates at 1 ml/33 kg bodyweight (300 mcg/kg) in young lambs:
Bodyweight | Dose |
Less than 4 kg | 0.1 ml |
5 - 6 kg | 0.2 ml |
7 - 10 kg | 0.3 ml |
11 - 13 kg | 0.4 ml |
14 - 16 kg | 0.5 ml |
For treatment of gastro-intestinal roundworms, lungworms and nasal bots, administer Dectomax solution for injection once at a dosage of 200 mcg doramectin per kilogram of bodyweight by the intramuscular route. Each ml contains 10 mg of doramectin, sufficient to treat 50 kg of bodyweight.
