Discovered and developed by scientists from the Merck Research Laboratories, IVOMEC contains ivermectin, a unique chemical entity. Its convenience, broad-spectrum efficacy and wide safety margin make it an excellent antiparasitic product for cattle, sheep and swine. One low-volume dose effectively controls internal and external parasites of cattle and swine and internal parasites of sheep that can impair health and productivity.


IVOMEC Injection is a ready-to-use sterile solution containing the following ingredients per mL: 10 mg ivermectin, 0.40 mL glycerol formal and propylene glycol q.s. ad 1 mL. IVOMEC Injection is formulated to deliver the recommended dose level of 200 µg ivermectin per kg of body weight in cattle and sheep when given subcutaneously at the rate of 1 mL per 50 kg. In swine, IVOMEC Injection is formulated to deliver the recommended dose level of 300 µg ivermectin per kg body weight when given subcutaneously at the rate of 1 mL per 33 kg. Studies show that IVOMEC Injection is stable for five years when stored under normal conditions.

Active Ingredient

Ivermectin is the first in a series of antiparasitic agents derived from the avermectin family of compounds. The avermectins are highly active, broad-spectrum antiparasitic agents isolated from fermentation of the soil organism Streptomyces avermitilis.

Eye worms: Thelazia spp.

Lungworms: *Dictyocaulus viviparus (adults and fourth stage larvae)

Cattle grubs (internal parasitic stages): Hypoderma bovis; H. lineatum

Sucking lice: Linognathus vituli; Haematopinus eurysternus; Solenopotes capillatus

Mites: Sarcoptes scabiei var. bovis; Psoroptes ovis (syn. P. communis var. bovis)

*IVOMEC Injection given at the recommended dosage controls infections of Dictyocaulus viviparus, Ostertagia ostertagi and Oesophagostomum radiatum for 21 days after treatment; Haemonchus placei, Trichostrongylus axei, Cooperia punctata and Cooperia oncophora for 14 days after treatment.


Cattle: Ivermectin Injection is to be given subcutaneously only, to reduce risk of potentially fatal clostridial infection of the injection site. Animals should be appropriately restrained to achieve the proper route of administration. Use of a 16-gauge, 1/2 to 3/4” needle is suggested. Inject under the loose skin in front of or behind the shoulder (see illustration).

When using the 50 mL, 250 mL or 500 mL package size, use only automatic syringe equipment. Use sterile equipment and sanitize the injection site by applying a suitable disinfectant. Clean, properly disinfected needles should be used to reduce the potential for injection site infections. No special handling or protective clothing is necessary.
