Dosage is 0.5 ml/50 kg bodyweight, equivalent to 1.0 mg moxidectin/kg bodyweight, given by a single subcutaneous injection in the ear. Determine cattle weight to ensure correct dose rate is used. Do not overdose. Do not use in animals less than 100kg or more than 500 kg body weight.

The injection should be given subcutaneously in the ear, using an 18 gauge, 25–40 mm hypodermic needle. Any single dose syringe may be used with the 50 ml bottle. The 50 ml vial stoppers must not be broached more than 20 times. Use automatic syringe equipment for the 200 ml vial. The dorsal (outer) surface of the ear should first be cleansed with antiseptic and allowed to briefly air dry. The injection should be given subcutaneously in the loose skin on the dorsal (outer) surface of the ear, just distal to (ie slightly away from) the edge of the ear cartilage (see diagram). To accomplish this, feel for the edge of the ear cartilage closest to the head, on the dorsal (outer) surface of the ear. From this landmark, taking care to avoid blood vessels (artery, vein), the needle is inserted subcutaneously starting at a point approximately 3 to 3.5 cm distal (away from the head) and directed towards the base of the ear. Advance the needle to the hub, then gently aspirate (pull back the plunger of) the syringe to confirm that the needle is not in a blood vessel. Upon injection, the resulting depot of injected material should end up a slight distance away from the edge of the ear cartilage. Following administration, the needle is withdrawn from the skin as pressure is applied for several seconds with the thumb at the point of insertion.

The injection site is approximately 3.5 cm (1.5 inches) away from the edge of the ear cartilage.

Use one hand to grasp and steady the ear.

Inject subcutaneously using an 18 gauge x 25-40 mm needle.

Inject contents. Depot should end up slightly away from the edge of the ear cartilage.

Apply pressure at the point of the ear cartilage.

Apply pressure at the point of insertion as the needle is withdrawn from the skin to help seal the opening.

Due to the long lasting protection against Dictyocaulus viviparus and the stomach worms, Ostertagia ostertagi and Haemonchus placei, a single treatment with CYDECTIN 10% LA for Cattle at turn-out helps control parasitic bronchitis (lungworm) and parasitic gastro-enteritis throughout the grazing season by reducing the build-up of infective larvae on pasture associated with these parasites. For best results the injection should be given to each calf of target weight to be grazed together immediately prior to being turned out to pasture. Animals should be set stocked throughout the grazing season or moved to a pasture which has not been grazed by other cattle earlier in the season.
