Panacur-wormer: In dogs, it is useful against roundworms, hookworms, and the more difficult to treat whipworms. It is effective against the Taenia species of tapeworm but not against the Common tapeworm, Dipylidium caninum. It is also effective against giardia (an intestinal protozoan which is contagious to both humans and pets) as well as several species of lungworm and even some flukes. http://www.marvistavet.com/html/body_panacur.html
