A method of producing a self-take anthelmintic that includes active components that are undesirable to at least one sense of a target animal. The active ingredients including praziquantel are mixed with artificial beef and yeast components and subjected to a first compression.

Thereafter, the material is subjected to a second compression to form a final self-take tablet.
