ADVERSE REACTIONS SECTION

LOINC: 34084-4Updated: 8/13/2025

ADVERSE REACTIONS

This product is likely to cause swelling at the injection site. Tissue damage at the injection site may also occur, including possible granulomas and necrosis. These reactions have resolved without treatment. Local tissue reaction may result in trim loss of edible tissue at slaughter. A single death attributed to clostridial infection associated with the injection of VALCOR® was reported in a non-pivotal effectiveness study. Observe cattle for injection site reactions. If injection site reactions are suspected, consult your veterinarian. This product is not for intravenous or intramuscular use. Hypersalivation may be observed; however, this reaction will disappear within a few hours. If this condition persists, a veterinarian should be consulted.

WARNINGS SECTION

LOINC: 34071-1Updated: 8/13/2025

WARNINGS AND PRECAUTIONS

WITHDRAWAL PERIODS AND RESIDUE WARNINGS:
Cattle must not be slaughtered for human consumption within 15 days following last treatment with this drug product. Not for use in female dairy cattle 20 months of age or older, including dry dairy cows; use in these cattle may cause drug residues in milk and/or in calves born to these cows or heifers. Not for use in beef calves less than 2 months of age, dairy calves, and veal calves. A withdrawal period has not been established for this product in pre- ruminating calves.

User Safety Warnings:
Not for human use. Keep out of reach of children. If accidental eye contact occurs, flush eyes immediately with water for 15 minutes and seek medical attention. If wearing contact lenses, flush eyes immediately with water before removing lenses then continue rinsing for at least 15 minutes. Do not eat, drink or smoke while handling the product. Wash hands after use. Take care to avoid accidental self-injection. If accidental injection occurs, seek medical attention and provide product package insert to medical professional. To obtain a Safety Data Sheet(s), contact Zoetis Inc. at 1-888-963-8471 or www.zoetis.com.

Animal Safety Warnings and Precautions:
Use of levamisole in cattle treated in the last few days with cholinesterase inhibitors such as organophosphates or with morantel may enhance the toxic effects of levamisole. Use together with caution.

Destruction of Hypoderma larvae (cattle grubs) at the period when these grubs are in vital areas may cause undesirable hostparasite reactions including the possibility of fatalities. Killing H. lineatum when it is in the tissue surrounding the gullet may cause bloat; killing H. bovis when it is in the vertebral canal may cause staggering or paralysis. These reactions are not specific to treatment with VALCOR™ and can occur with any successful treatment of grubs. Cattle should be treated either before or after these stages of grub development. Consult your veterinarian concerning the proper time for treatment. Follow recommended dosage carefully.

Reproductive safety has not been evaluated in bulls intended for breeding.

Environmental Warnings:
Studies indicate that when doramectin comes in contact with the soil, it readily and tightly binds to the soil and becomes inactive over time. Free doramectin may adversely affect fish and certain aquatic organisms. Do not permit water runoff from feedlots to enter streams or ponds. Do not contaminate water by direct application or by the improper disposal of drug containers. Dispose of containers in an approved landfill or by incineration.

As with other avermectins, doramectin is excreted in the dung of treated animals and can inhibit the reproduction and growth of pest and beneficial insects that use dung as a source of food and for reproduction. The magnitude and duration of such effects are species and life-cycle specific. When used according to label directions, the product is not expected to have an adverse impact on populations of dung-dependent insects.

Other Warnings:
Parasite resistance may develop to any dewormer and has been reported for most classes of dewormers. Treatment with a dewormer used in conjunction with parasite management practices appropriate to the geographic area and the animal(s) to be treated may slow the development of parasite resistance. Fecal examinations or other diagnostic tests and parasite management history should be used to determine if the product is appropriate for the herd, prior to the use of any dewormer. Following the use of any dewormer, effectiveness of treatment should be monitored (for example, with the use of a fecal egg count reduction test or another appropriate method). A decrease in a drug’s effectiveness over time as calculated by fecal egg count reduction tests may indicate the development of resistance to the dewormer administered. Your parasite management plan should be adjusted accordingly based on regular monitoring.

DESCRIPTION SECTION

LOINC: 34089-3Updated: 8/13/2025

DESCRIPTION

VALCOR® injection is a ready-to-use, colorless to pale yellow, sterile solution containing 0.5% w/v doramectin and 15% w/v levamisole hydrochloride, for subcutaneous administration at a dose rate of 1 mL/25 kg of body weight to deliver a dose of 0.2 mg of doramectin and 6 mg of levamisole hydrochloride per kg of body weight. Each mL of VALCOR® contains 150 mg levamisole hydrochloride, 5 mg doramectin, 20 mg benzyl alcohol, 2.5 mg meglumine, 0.1 mg butylated hydroxyanisole (BHA), 0.1 mg butylated hydroxytoluene (BHT), and glycerol formal q.s.

DOSAGE & ADMINISTRATION SECTION

LOINC: 34068-7Updated: 8/13/2025

DOSAGE AND ADMINISTRATION

Inject subcutaneously in the neck as a single dose at a dosage of 0.2 mg doramectin (0.091 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 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.
