It is a sterile suspension indicated for use in lactating dairy cattle for (1) the treatment of clinical mastitis associated with Coagulase-Negative Staphylococci, Streptococcus Dysgalactiae, and Escherichia Coli and (2) the treatment of diagnosed subclinical mastitis associated with Coagulase-Negative Staphylococci and Streptococcus Dysgalactiae.

Ceftiofur is a broad-spectrum cephalosporin antibiotic that exerts its effect by inhibiting bacterial cell wall synthesis. Like other ß-lactam antimicrobial agents, cephalosporins inhibit cell wall synthesis by interfering with the enzymes essential for peptidoglycan synthesis. This effect results in lysis of the bacterial cell and accounts for the bactericidal nature of these agents. Ceftiofur has demonstrated in vitro activity against coagulase-negative staphylococci, Streptococcus dysgalactiae, and Escherichia coli.

As with all drugs, the use of SPECTRAMAST LC Sterile Suspension is contraindicated in animals previously found to be hypersensitive to the drug. This formulation is clinically safe and non-irritating to the udder of lactating dairy cows.

Keep away from children and animals. Following intramammary infusion with antibiotics in lactating cows, milk obtained during treatment and during the milk discard period should be properly discarded and not fed to calves. SPECTRAMAST LC is intended for use in lactating dairy cattle with mastitis associated only with the specified labeled pathogens. To assure responsible antimicrobial drug use, it is expected that subclinical mastitis will be diagnosed using a positive culture or other pathogen-specific test in addition to any other appropriate veterinary medical evaluation prior to treatment. Cows with systemic clinical signs caused by mastitis should receive other appropriate therapy under the direction of a licensed veterinarian. After successful treatment, reinfection may occur unless good herd management, sanitation, and mechanical safety measures are practiced. Affected cows should be watched carefully to detect recurrence of infection and possible spread to other animals. * Penicillins and cephalosporins can cause allergic reactions in sensitized individuals. Topical exposures to such antimicrobials, including ceftiofur, may elicit mild to severe allergic reactions in some individuals. Repeated or prolonged exposure may lead to sensitization. Avoid direct contact of the product with the skin, eyes, mouth and clothing. Sensitization of the skin may be avoided by wearing protective gloves. Persons with a known hypersensitivity to penicillin or cephalosporins should avoid exposure to this product. In case of accidental eye exposure, flush with water for 15 minutes. In case of accidental skin exposure, wash with soap and water. Remove contaminated clothing. If allergic reaction occurs (e.g., skin rash, hives, difficult breathing), seek medical attention.
