Dosage & Administration

A single dose of 6 mg gamithromycin/kg body weight (equivalent to 1 ml/25 kg body weight) into the neck (cattle and pigs) or anterior to the shoulder (sheep). To ensure correct dose, body weight should be determined as accurately as possible to avoid underdosing.

  • Subcutaneous injection.
  • For treatment of cattle over 250 kg and sheep over 125 kg body weight, divide the dose so that no more than 10 ml (cattle) or 5 ml (sheep) are injected at a single site.


  • Intramuscular injection.
  • The injection volume should not exceed 5 ml per injection site.

The cap may be safely punctured up to 60 times. For multiple vial entry, an automatic dosing device is recommended to avoid excessive broaching of the stopper.
