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.

Feed for one (1) day. No prior withdrawal of feed or water necessary. When feed containing Safe-Guard® has been fed for 1 day according to the above rates, a total intake of 2.27 mg fenbendazole per pound of body weight is assured.

Store at or below 25 °C (77 °F).

Excursions up to 40 °C (104 °F) are permitted.


Safe-Guard Cattle Top Dress Pellets must be spread uniformly on top of the daily ration. Sufficient bunk space must be available so all animals can eat at the same time to ensure uniform consumption of the pellets. All cattle must be eating normally to ensure that each animal consumes an adequate amount of the pellets.

Withdrawal Periods and Residue Warnings: Milk taken during treatment and for 60 hours after the last treatment must not be used for human consumption. Cattle must not be slaughtered for human consumption within 13 days following last treatment with this drug product. 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.

WARNING: KEEP THIS AND ALL DRUGS OUT OF THE REACH OF CHILDREN. NOT FOR USE IN HUMANS. The Safety Data Sheet (SDS) contains more detailed occupational safety information. For customer service, adverse effects reporting, and/or a copy of the SDS, call 1-800-211-3573. For additional information about adverse drug experience reporting for animal drugs, contact FDA at 1-888-FDAVETS, or

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.

Colorado Serum


GENERAL INFORMATION: This product has been shown to be effective for the vaccination of healthy horses, cattle, sheep, goats, and swine against tetanus. This product was licensed prior to the requirement to establish a minimum age for use. The duration of immunity is unknown. For more information regarding efficacy and safety data, see

Safety in pregnant animals is unknown.

Tetanus Toxoid is prepared by detoxifying tetanus toxin in such a manner as to allow the antigenic properties to remain intact. Product is purified, concentrated and adjuvanted to provide a low dose effective immunizing agent.

Each serial is tested for purity, safety, and potency in accordance with USDA requirements.

Tetanus is caused by a neurotoxin produced by growth of Clostridium tetani, an anaerobic (lives without air) micro-organism, in necrotic tissue. Affected animals become stiff, have difficulty swallowing, and have an increased pulse rate. Breathing is labored. Spasmodic contractions of the muscular system occur, such as contracting muscles of the jaw.

Spasmodic contractions of the muscular system occur, such as contracting muscles of the jaw. Thus, the term “lockjaw” is often used. Legs and tail are often stiff with abdominal muscles contracted. Tetanus stricken animals may be unusually sensitive to light and heat. Temperature of the animal generally remains normal, elevating only shortly before death.

Protective antibody levels usually occur about two weeks after the second injection of the primary immunization series. In contrast, administration of Tetanus Antitoxin is recommended for immediate, emergency, passive treatment of exposed animals with unknown vaccination history or with signs of tetanus infection.

DIRECTIONS: Do not vaccinate within 21 days before slaughter. Store at 2-8° C. Do not freeze. Do not mix with other products. Shake well before use. Use entire contents when first opened.

PRECAUTIONS: A transitory local reaction may occur at injection site. Anaphylactoid reaction may occur following administration of products of this nature. If noted, administer adrenalin or equivalent. In case of human exposure, consult a physician.

DOSAGE & ADMINISTRATION: For primary immunization, two doses should be administered subcutaneously or intramuscularly approximately 30 days apart. Use intramuscularly for horses as local reactions are more likely to occur if injected subcutaneously.

Horses: 1 ml IM

Cattle: 1 ml SC or IM

Sheep, Goats, Swine: 0.5 ml SC or IM

Historically, annual single dose revaccination has been recommended. Contact veterinarian for advice.

OTHER INFORMATION: Contains thimerosal and formalin as preservatives. Tetanus Toxoid Concentrate is available in single dose size packaged 10 vials to the carton, and in 10 dose vials.
