IVOMEC Classic Injection for Cattle and Sheep 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 with the following parasites of cattle:

Prolonged Activity
Dictyocaulus viviparus up to 28 days
Ostertagia ostertagi up to 21 days
Oesophagostomum radiatum up to 21 days
Cooperia spp. up to 14 days
Trichostrongylus axei up to 14 days
Haemonchus placei up to 14 days

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.

Ostertagia circumcincta
O. trifurcata
Haemonchus contortus
Trichostrongylus axei
T. colubriformis
T. vitrinus
Cooperia curticei
O. venulosum
Nematodirus filicollis
Chabertia ovina
Trichuris ovis
Dictyocaulus filaria
Protostrongylus rufescens
Adult Stages
Nasal Bots:
Oestrus ovis
Mange Mites:
Psoroptes ovis

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.

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, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.
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.

Lactating ewes

dave merriman

is it safe to use Ivomectin in lactating ewes as a treatment for coccidiosis?

  • VioVet Staff

IVOMEC Classic Injection for Cattle and Sheep can be administered to
cows and ewes at any stage of pregnancy or lactation provided that the
milk is not intended for human consumption. Ivomec contains Ivermectin though which is not effective against coccidia, I recommend using a coccidiostat wormer instead. Vecoxan is an over the counter coccidia treatment but it is intended for use in lambs/calves, coccidia is not a disease that normally affects adult ewes significantly. I recommend discussing treating the condition with your vet as prescription medications may be required.

Using for dogs

Ella Hever

  • VioVet customer since 2016
  • From: , Israel

Can this product be used for dogs?
Thank you

  • VioVet Staff

The active ingredient, Ivermectin, can be used in some breeds of dog safely but Ivomec is only licensed for use in cattle and sheep. This means any use in dogs is off license, I recommend contacting your vet for off license medication advice.

Can you administer orally instead of injection

  • VioVet Staff

Ivomec comes in either injectable or pour-on form, not oral. You can find the pour on version in the link here.
