Valcor (Doramectin/Levamisole) Injection for Cattle

Cattle wormer, Valcor (doramectin and levamisole injection), is labled for the treatment and control of gastrointestinal roundworms, lungworms, eyeworms, grubs, sucking lice, and mange mites in beef cattle 2 months of age and older and in replacement dairy heifers less than 20 months of age. Not for use in beef bulls intended for breeding over 1 year of age, dairy calves, and veal calves. This injectable cattle wormer is the first and only combination endectocide in the United States that offers protection against internal and external parasites in cattle.

Inject this cattle wormer subcutaneously in the neck as a single dose at a dosage of 0.2 mg doramectin (0.91 mg/lb) and 6 mg of levamisole hydrochloride per kg (2.72 mg/lb) of body weight. Each mL of Valcor contains 5 mg doramectin and 150 mg of levamisole hydrochloride which is sufficient to treat 55 lb (25 kg) of body weight. Do not inject more than 10 mL per injection site. 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.

Use this cattle wormer product within 45 days of the first puncture. Puncture the 100 mL vial a maximum of 6 times and the 250 mL and 500 mL vials a maximum of 28 times, using a luer-lock syringe and needle no larger than 18 gauge. If anticipated to exceed maximum number of punctures, the use of automatic injection equipment or a repeater syringe is recommended. When using a draw-off spike or needle with bore diameter larger than 18 gauge, discard any product remaining in the vial immediately after use. Cattle must not be slaughtered for human consumption within 15 days following last treatment with this drug product.
