Presentation

Solution for injection containing gamithromycin 150mg/ml. Also contains monothioglycerol 1mg/ml.

Uses

For use in cattle for therapeutic and preventative treatment of bovine respiratory disease (BRD) associated with Mannheimia haemolytica, Pasteurella multocida and Histophilus somni.

The presence of the disease in the herd should be established before preventative treatment.

Dosage and administration

A single subcutaneous injection of 6 mg gamithromycin/kg bodyweight (equivalent to 1 ml/25 kg bodyweight) in the neck.

To ensure correct dosage bodyweight should be determined as accurately as possible to avoid underdosing.

Contra-indications, warnings, etc

Keep out of the reach and sight of children.

For animal treatment only

Do not use in case of hypersensitivity to macrolide antibiotics or to any of the excipients.

Cross-resistance may occur with other macrolides. Avoid simultaneous administration of antimicrobials with a similar mode of action such as other macrolides or lincosamides.

Use of the product should be based on susceptibility testing and take into account official and local policies on the use of antimicrobials in farm animals.

During clinical trials transient injection site swellings were observed. Visible injection site swellings may develop in up to 45% of treated animals associated with occasional, slight pain evident for one day. The swellings typically resolve within 3 to 14 days but may persist in some animals for up to 35 days after treatment.

Clinical studies have demonstrated the wide margin of safety for gamithromycin injection in cattle. In a young adult cattle study, gamithromycin was administered by subcutaneous injection at 6, 18 and 30 mg/kg (1, 3 and 5 times the recommended dose) and repeated three times at 0, 5 and 10 days (three times the recommended duration of use). Injection site reactions were noted in a dose-related manner.

Based on laboratory animal data, gamithromycin has not produced any evidence of selective developmental or reproductive effects. The safety of gamithromycin during pregnancy and lactation has not been evaluated in cattle. Use only according to the risk/benefit assessment by the responsible veterinarian.
