The recommended dosage rate is 15 mg/kg bodyweight, which is equivalent to 1 ml/10 kg. If necessary, the dose may be repeated after 48 hours.
The following is intended as a guide |
Animal | Specimen weight (kg) | Dose (volume) |
Sheep | 65 | 6.5 ml |
Lamb | 10 | 1.0 ml |
Dog – large | 35 | 3.5 ml |
– medium | 20 | 2.0 ml |
– small | 10 | 1.0 ml |
Cat | 5 | 0.5 ml |
Shake the vial well before use. Inject by the subcutaneous or intramuscular route (dogs and cats) or the intramuscular route only (sheep), then massage the injection site. (For ease of administration in dogs and cats, needles no finer than 20 gauge should be used). If the volume to be given is greater than 5 ml (sheep) it should be divided and injected into two separate sites. The suspension is not suitable for intravenous or intrathecal administration.
In common with other penicillin preparations, hydrolysis takes place rapidly in the presence of water. It is important, therefore, that a dry syringe is used when extracting suspension for injection, to avoid contaminating the remaining contents of the vial with drops of water. Do not broach the vial more than 40 times.
