The table below indicates some usual dosing recommendations for milbemycin oxime issued by manufacturers or documented in the scientific literature. They may not be approved in some countries.
|Dosing recommendations for MILBEMYCIN OXIME
|Warning!: Tolerance and safety margin in dogs with the MDR-1 mutation (e.g. Collies) sensitive to ivermectin are higher for milbemycin oxime than for ivermectin. Consequently the recommended dose can be admnistered to dogs with de MDR-1 mutation, however puppies are more sensitive. In sensitive dogs the recommended dose of 0.5 mg/kg should not be exceeded bacause the therapeutic margin is lower than in the non-sensite dogs.|
