Guest guest Posted April 14, 2006 Report Share Posted April 14, 2006 I was wondering if anyone know if a topical dog treatment we use which is made by Pfizer and called Revolution which is a heart worm and tick parasite treatment could be toxic. The active ingredient is selamectin which contains (5Z,25S)-25-cyclohexyl-4'-O-de(2,6-dideoxy-3-0-methyl-sigma-L-arabino-hexopy ranoayl)-5-demethoxy-25-de(1-methylpropyl)-22,23-dihydro-5-hydroxyiminoaverm ectin A1a. If this is toxic, does anyone know of a less toxic treatment? Thanks! Dave Quote Link to comment Share on other sites More sharing options...
