Ivomec Classic Injection for Cattle and Sheep is a sterile non-aqueous solution for injection containing 10 mg/ml ivermectin.


Ivomec Classic Injection for Cattle and Sheep is indicated for the effective treatment and control of roundworms, lungworms and eyeworms when given at the recommended dosage level of 200 mcg ivermectin per kg bodyweight to sheep and cattle.

It may also be used as an aid in the control of biting lice (Damalinia bovis) and the mange mite (Chorioptes bovis), but complete elimination may not occur.

Persistent Activity in Cattle:

When cattle have to graze on pasture contaminated with infective larvae of cattle nematodes, treatment with Ivomec Classic Injection for Cattle and Sheep at the recommended dose rate of 1ml per 50kg bodyweight controls re-infection.

To obtain optimal benefit from the persistent activity of Ivomec Classic Injection for Cattle and Sheep for grazing animals, it is recommended that calves which are set-stocked in the first grazing season should be treated 3, 8 and 13 weeks after the day of turn-out. This can protect the animals from parasitic gastro-enteritis and lungworm disease throughout the grazing season, provided they are set-stocked, all the calves are included in the programme and that no untreated cattle are added to the pasture. Treated animals should always be monitored according to good husbandry practices.

For the treatment and control of sheep scab Psoroptes ovis, two injections with a seven-day interval are required to treat clinical signs of scab and to eliminate mites. Benzimidazole-resistant strains of Haemonchus contortus and Ostertagia circumcincta are also controlled. Sheep scab (Psoroptes ovis) is an extremely contagious external parasite of sheep. Following treatment of infected sheep, great care must be taken to avoid re-infestation, as mites may be viable for up to 15 days off the sheep. It is important to ensure all sheep which have been in contact with infected sheep are treated. Contact between treated infected and non-treated, non-infected flocks must be avoided until at least 7 days after the last treatment.

Dosage and Administration:

Ivomec Classic Injection for Cattle and Sheep should be given only by subcutaneous injection, using aseptic precautions, at the recommended dosage level of 200 mcg ivermectin per kg bodyweight under the loose skin in front of, or behind, the shoulder in cattle and in the neck in sheep. To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Cattle: For cattle dose at the rate of 1ml per 50kg of bodyweight.

Sheep: For sheep dose at the rate of 0.1ml per 5kg of bodyweight.

When treating sheep of less than 16kg, seek veterinary advice regarding the use of 1 ml disposable syringes graduated in increments of 0.1 ml. For the treatment of individual sheep, a syringe not exceeding 2.0 ml and calibrated in increments of 0.1 ml should be used.

The injection may be given with any standard automatic or single-dose or hypodermic syringe. Use of a sterile 17 gauge × ½ inch needle is suggested. Replace with a fresh sterile needle after every 10 to 12 animals. Injection of wet or dirty animals is not recommended.
