CLEAR WORMER is a dog wormer from BOB MARTIN containing nitroscanate, a generic version of ELANCO's LOPATOL.
Nitroscanate is a broad-spectrum anthelmintic effective against gastrointestinal roundworms and tapeworms introduced in the late 1970s ((by CIBA-GEIGY → NOVARTIS → ELANCO). Use in dogs is moderate to low, particularly after the introduction of more modern dog wormers in the last two decades. It is neither used in livestock, nor in agriculture.
