> **Important Note for Producers**: This medication is primarily used in dairy and beef cattle for localized infections. * **Administration Technique**: Ensure the teat end or vulva is thoroughly cleaned and disinfected with alcohol before infusion to prevent introducing new environmental bacteria. * **Withdrawal Times**: Strictly follow the prescribed milk discard and slaughter withdrawal times to prevent illegal drug residues in the food supply. Note that low-producing cows may require extended withdrawal periods. * **Allergic Reactions**: Watch for signs of hypersensitivity, such as hives, swelling, or sudden breathing difficulty. Contact your veterinarian immediately if these occur.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

- > **Cross-Reactivity**: Use cautiously in patients with documented hypersensitivity to other beta-lactam antibiotics (e.g., penicillins, cefamycins, carbapenems) due to potential cross-reactivity. * **Pregnancy**: Cephalosporins cross the placenta.
