Please note that these directions refer to products containing Milbemycin Oxime only, and may not be applicable to products containing a combination of ingredients.

Milbemycin Oxime tablets may be offered directly to the animal as a treat, added to food, or administered as a tablet medication. Monitor the animal to ensure that no part of the tablet is lost or rejected. If it is not entirely consumed, redose once with the full recommended dose as soon as possible.

The most common problems caused by Milbemycin Oxime occur from incorrect dosing. Ensure that you are using the correct product for your animal’s type and weight; never use a product intended for dogs to treat cats.
