Products that cause sudden death or paralysis of ascarids, particularly [[Parascaris equorum|''Parascaris equorum'']] within the small intestine.  Adult ascarids are large and thus readily cause small intestinal impaction.  It has been suggested that disruption of the surface of the ascarid releases antigenic fluids that inhibit intestinal muscular activity, thereby increasing the likelihood of intestinal obstruction.  Anthelmintics that are suspected to induce episodes of ascarid impaction include(37):
