DOSAGE:
Cattle:Vetrimec 1% Injection should be given only by subcutaneous injection under the loose skin in front of or behind the shoulder at the recommended dose level of 200 mcg of ivermectin per kilogram of body weight. Each mL of Vetrimec 1% contains 10 mg of ivermectin, sufficient to treat 110 lb (50 kg) of body weight (maximum 10 mL per injection site).
Swine: Vetrimec 1% Injection should be given only by subcutaneous injection in the neck of swine at the recommended dose level of 300 mcg of ivermectin per kilogram (2.2 lb) of body weight. Each mL of Vetrimec 1% contains 10 mg of ivermectin, sufficient to treat 75 lb of body weight.
Do not underdose. Ensure each animal receives a complete dose based on a current body weight. Underdosing may result in ineffective treatment, and encourage the development of parasite resistance.
ADMINISTRATION
Cattle: Vetrimec 1% 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, 500 mL or 1000 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.
Swine: Vetrimec 1% (ivermectin) Injection is to be given subcutaneously in the neck. Animals should be appropriately restrained to achieve the proper route of administration. Use of a 16- or 18- gauge needle is suggested for sows and boars, while an 18- or 20- gauge needle may be appropriate for young animals. Inject under the skin, immediately behind the ear (see illustration).
When using the 50 mL, 250 mL, 500 mL or 1000 mL package size, use only automatic syringe equipment. As with any injection, sterile equipment should be used. The injection site should be cleaned and disinfected with alcohol before injection. The rubber stopper should also be disinfected with alcohol to prevent contamination of the contents. Mild and transient pain reactions may be seen in some swine following subcutaneous administration.
Recommended Treatment Program
Swine:At the time of initiating any parasite control program, it is important to treat all breeding animals in the herd. After the initial treatment, use Vetrimec 1% (ivermectin) Injection regularly as follows:
BREEDING ANIMALS
Sows: Treat prior to farrowing, preferably 7-14 days before, to minimize infection of piglets.
Gilts: Treat 7-14 days prior to breeding.
Treat 7-14 days prior to farrowing.
Boars: Frequency and need for treatments are dependent upon exposure. Treat at least two times a year.
FEEDER PIGS
(Weaners/Growers/Finishers)
All weaner/feeder pigs should be treated before placement in clean quarters.
Pigs exposed to contaminated soil or pasture may need retreatment if reinfection occurs.
NOTE:
(1) Vetrimec 1% Injection has a persistent drug level sufficient to control mite infestations throughout the egg to adult life cycle. However, since the ivermectin effect is not immediate, care must be taken to prevent reinfestation from exposure to untreated animals or contaminated facilities. Generally, pigs should not be moved to clean quarters or exposed to uninfested pigs for approximately one week after treatment. Sows should be treated at least one week before farrowing to minimize transfer of mites to newborn baby pigs.
(2) Louse eggs are unaffected by Vetrimec 1% Injection and may require up to three weeks to hatch. Louse infestations developing from hatching eggs may require retreatment.
(3) Consult a veterinarian for aid in the diagnosis and control of internal and external parasites of swine.
Special Minor Use
Reindeer: For the treatment and control of warbles (Oedemagena tarandi) in reindeer, inject 200 micrograms ivermectin per kilogram of body weight, subcutaneously. Follow use directions for cattle as described under ADMINISTRATION.
American Bison: For the treatment and control of grubs (Hypoderma bovis) in American bison, inject 200 micrograms ivermectin per kilogram of body weight, subcutaneously. Follow use directions for cattle as described under ADMINISTRATION.
