DOSAGE & ADMINISTRATION SECTION

LOINC: 34068-7Updated: 5/1/2025

DOSAGE AND ADMINISTRATION:

Enrofloxacin 100 mg/mL provides flexible dosages and durations of therapy.

Enrofloxacin 100 mg/mL may be administered as a single dose for one day for treatment and control of BRD (cattle), for treatment and control of SRD or for control of colibacillosis (swine), or for multiple days for BRD treatment (cattle). Selection of the appropriate dose and duration of therapy for BRD treatment in cattle should be based on an assessment of the severity of the disease, pathogen susceptibility and clinical response.

Cattle:

**Single-Dose Therapy (BRD Treatment):**Administer, by subcutaneous injection, a single dose of 7.5-12.5 mg/kg of body weight (3.4-5.7 mL/100 lb).

**Multiple-Day Therapy (BRD Treatment):**Administer daily, a subcutaneous dose of 2.5-5 mg/kg of body weight (1.1-2.3 mL/100 lb). Treatment should be repeated at 24-hour intervals for three days. Additional treatments may be given on Days 4 and 5 to animals that have shown clinical improvement but not total recovery.

Single-Dose Therapy (BRD Control): Administer, by subcutaneous injection, a single dose of 7.5 mg/kg of body weight (3.4 mL/100 lb). Examples of conditions that may contribute to calves being at high risk of developing BRD include, but are not limited to, the following:

  • Transportation with animals from two or more farm origins.
  • An extended transport time with few to no rest stops.
  • An environmental temperature change of ≥30°F during transportation.
  • A ≥30°F range in temperature fluctuation within a 24-hour period.
  • Exposure to wet or cold weather conditions.
  • Excessive shrink (more than would be expected with a normal load of cattle).
  • Stressful arrival processing procedures (e.g., castration or dehorning).
  • Exposure within the prior 72 hours to animals showing clinical signs of BRD.

Administered dose volume should not exceed 20 mL per injection site.

*Dose volumes have been rounded to the nearest 0.5 mL within the dose range.

Swine:
Administer, either by intramuscular or subcutaneous (behind the ear) injection, a single dose of 7.5 mg/kg of body weight (3.4 mL/100 lb). Administered dose volume should not exceed 5 mL per injection site.

For the control of colibacillosis, administration should be initiated within the first 60 days post-weaning when clinical signs are present in at least 2% of the animals in the group. If no improvement is noted within 48 hours, the diagnosis should be reevaluated.
