Resflor for Cattle

Resflor 250mL Injection is intended for cattle under the applicable product authorization.

Bovine respiratory disease is a complex condition that can involve multiple bacterial and viral pathogens, environmental factors and management stress.

Risk factors may include:

• Transportation
• Weaning
• Commingling
• Poor ventilation
• Temperature changes
• Overcrowding
• Nutritional stress
• Other underlying infections

Early veterinary assessment can help determine whether antimicrobial treatment is appropriate.

Florfenicol and Flunixin Meglumine

The combination in RESFLOR GOLD brings together two pharmacologically different active ingredients.

Florfenicol is an antimicrobial used against susceptible bacterial pathogens.

Flunixin meglumine is a non-steroidal anti-inflammatory drug (NSAID) used to control inflammation and fever.

The FDA describes RESFLOR GOLD as an antimicrobial and NSAID combination.

This combination does not mean that every case of respiratory disease will respond to treatment. Correct diagnosis and appropriate antimicrobial selection remain important.

Resflor and Bovine Respiratory Disease

RESFLOR GOLD is approved in the U.S. for treatment of BRD associated with Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis, along with control of BRD-associated pyrexia in beef and non-lactating dairy cattle.

Respiratory disease may present with:

• Fever
• Coughing
• Nasal discharge
• Increased respiratory effort
• Depression
• Reduced appetite
• Reduced activity
• Poor growth
• Reluctance to move

Cattle showing significant respiratory signs should be assessed promptly by a veterinarian.

Signs of Respiratory Disease in Cattle

Recognizing respiratory illness early can be important for herd health.

Producers should monitor cattle for changes in:

Respiration: increased breathing effort, coughing or abnormal respiratory sounds.

Temperature: elevated body temperature may accompany infectious disease.

Appetite: sick cattle may eat less or stop eating.

Behavior: affected animals may become depressed or less responsive.

Nasal discharge: discharge can occur with respiratory infections.

A diagnosis should not be based on a single symptom. Veterinary examination and herd-level disease information can help determine the appropriate treatment strategy.

Resflor 250mL Injection Dosage and Administration

The correct dosage should always be taken from the current label applicable to the product and country.

For the U.S. RESFLOR GOLD label, the labeled dose is 40 mg florfenicol/kg body weight plus 2.2 mg flunixin/kg body weight, equivalent to 2 mL per 15 kg (6 mL per 100 lb) once, administered subcutaneously. The U.S. label specifies administration in the neck and limits the amount to 10 mL per injection site.

Do not assume these instructions apply to every product sold under the Resflor name internationally.

The 250mL bottle is the package size, not a single-animal dose.

Safety and Precautions

Resflor contains an antimicrobial and an NSAID, so appropriate veterinary oversight is important.

The current U.S. labeling includes reproductive and periparturient precautions relating to flunixin. The FDA notes that reproductive performance, pregnancy and lactation effects have not been determined and warns about potential effects around calving.

Before treatment, discuss the animal’s:

• Pregnancy status
• Reproductive status
• Medical history
• Current medications
• Previous treatment
• Hydration status
• Disease severity

Do not administer Resflor to animals or species outside the approved label without specific veterinary direction.

Withdrawal and Food-Animal Considerations

Because Resflor is used in food-producing cattle, withdrawal requirements are especially important.

Withdrawal periods vary according to the exact product, country and regulatory approval. The current U.S. label should be consulted for applicable meat and other food-safety requirements rather than relying on information from an unrelated market.

Never sell or slaughter treated cattle for food outside the applicable withdrawal requirements.

Responsible Antibiotic Use

Florfenicol is an antimicrobial, so responsible use is important.

Antibiotics should be used when a susceptible bacterial infection is appropriately diagnosed or when treatment meets the applicable veterinary indication.

Responsible antimicrobial management includes:

• Veterinary diagnosis
• Appropriate product selection
• Correct dosing
• Correct administration
• Following the complete labeled treatment instructions
• Maintaining treatment records
• Monitoring response
• Avoiding unnecessary antimicrobial use

If cattle do not respond as expected, veterinary reassessment may be necessary.

Storage and Handling

Store Resflor 250mL Injection according to the current manufacturer’s instructions.

Before use, inspect:

• Product name
• Active ingredients
• Concentration
• Expiration date
• Bottle integrity
• Storage conditions
• Appearance of the solution

Do not use an expired, damaged or improperly stored injectable product.
