Resflor vet.
ATC code
Species
Cattle.
Indications
Treatment of respiratory infections caused by Mannheimia haemolytica, Pasteurella multocida, Mycoplasma bovis and Histophilus somni associated with pyrexia.
Dose to be administered and administration route
Subcutaneous use.
40 mg/kg florfenicol and 2.2 mg/kg flunixin (2 mL/15 kg body weight) to be administered by a single injection.
The dose volume given at any one injection site should not exceed 10 mL.
It is recommended to treat animals in the early stages of the disease and to evaluate the response to treatment 48 hours after injection. The anti-inflammatory component of the veterinary medicinal product, flunixin, may mask a poor bacteriological response to florfenicol in the first 24 hours after injection. If clinical signs of respiratory disease persist or increase, or if relapse occurs, treatment should be changed, using another antibiotic, and continued until clinical signs have resolved.
The injection should only be given in the neck.
Swab septum before removing each dose. Use a dry sterile needle and syringe.
To ensure a correct dosage, body weight should be determined as accurately as possible.
Adverse reactions
Cattle:
|
Very common
(>1 animal / 10 animals treated): |
Injection site swelling1 |
|
Very rare
(<1 animal / 10,000 animals treated, including isolated reports): |
Anaphylactic-type reaction2 |
1 becomes palpable 2-3 days after subcutaneous injection. The duration of the injection site swellings ranged from 15-36 days post-injection. Grossly, this is associated with minimal to mild irritation of the subcutis. Extension into the underlying muscle was noted in only a few instances. By 56 days post-dosing, no gross lesions were observed that would require any trim-out at slaughter.
2these reactions may be fatal.
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.
