Dosage and Administration

For intramuscular or subcutaneous administration to cattle and intramuscular administration to pigs at a single dose rate of 1 mL per 15 kg of live bodyweight (20 mg oxytetracycline per kg bodyweight).

It is recommended that the maximum dose at any one site is 10 mL in cattle and 5 mL in pigs to minimize local tissue irritation at the injection site. Intramuscular injections should be made deep into the fleshy part of the muscle such as the neck. Subcutaneous injections should be administered in the neck region.

Following administration, temporary localised swelling may be observed at the site of injection for several days. This is due to the high concentration and long acting effect of the product.

NOROMYCIN™ LA 300 Injectable Solution should be warmed to body temperature prior to administration.

If clinical improvement is not observed after 48 hours, clinical re-evaluation may be required. In non-responsive cases, consideration may be given to the use of an alternative antibiotic.

Note: Treatment with Noromycin™ LA 300 only, in severe disease cases, may be insufficient.
