After injection, grasp the end of the teat firmly, then gently massage the medication up the teat canal into the milk cistern.

Treated quarters should not be milked for at least six hours after treatment but should be milked at regular intervals thereafter. Treatment may be repeated at 12 hour intervals, up to a total of three doses, as indicated by the clinical response.
